Research using litchi extracts have shown that they contain powerful antioxidants and flavonoids and have anticancer effects, which are especially effective against breast cancer cells . 'Mauritius' and especially 'Brewster' flower irregularly from year to year causing unreliable cropping. Flowering induction occurred every first Winter after planting. Drew, H. 1999. Pepper spot - a new disease affecting lychees in Australia. Pineapple slips weighing 120 g to 200 g each were planted on the first fortnights of September through December 1981 and January 1982. Whole trees that had been tip pruned at anthesis to simulate hedging, were sprayed twice (pre and post anthesis) with AVG at concentrations of 60 ppm in 2007 (10-year-old ‘A4’ trees) and 400 ppm in 2008 (6-year-old ‘849’ trees). This may indicate an alternative to ethylene as the primary regulator of abscission of young macadamia fruit. 40, No. III. The predominant pathogen associated with fruit decay was Alternaria alternata (Fr.) Abstract─ Bacterial leaf blight of litchi (Litchi chinensis Sonn.) (litchi). The changing dynamics of pests and the emerging new pests and diseases may become a hindrance to profitable litchi cultivation and will have socioeconomic impact on litchi growing areas. 4. here I discuss about some tips to control disease and pest of litchi. developing mainpulating strategies to increase lychee productivity. Deficit irrigation with drip system (60 % ETc) resulted in higher reducing sugar content (10.2 %) in the litchi pulp. Leaf type: odd-pinnately compound; made up of 4-8 leaflets. The objective of the present research was to evaluate Cavendish banana clones collected from different sites. ‘Duke 6’ leaves. Litchi is host to a range of post-harvest pathogens, often with quite different modes of infection. The field collected samples of litchi fruits, affected by fruit cracking, revealed that the exposed aril in the cracks was colonized by Aspergillus flavus. Deficit irrigation showed great potential to increase the irrigation water use efficiency of litchi production with slight deviation in potential yield. Realtime data on losses and quality parameters of fruits were recorded by transporting litchi from Muzaffarpur to Delhi (distance 1000 km) by truck. She received USDA certification in food components, nutrient sources, food groups and infant/child nutrition, and holds a B.A. New Delhi, pp 101-105, Effect of disinfection dose of irradiation on the physiology of Taiso lychee, In: Thind TS (ed) Diseases of fruits and vegetables and their management, Mishra AK, Pandey BK (2001) Disease of litchi and their management. The results indicated that trees having highly damaged canopies (>50% foliage) by these pests represented as much as 40.0% while partially damaged (10-30% foliage) plants represented were up to 20.8%. Leaf blight was common in all 7 varieties viz. Leaf, panicle and fruit blights of litchi (Litchi chinensis Sonn.) significantly higher fruit flesh Mn concentration, and significantly lower and Williams. Keissler. The aim of this study was to assess the effect of the ethylene inhibitor aminoethoxyvinylglycine (AVG) on fruit abscission in, Lychee (Litchi chinensis Sonn.) Fruit were analysed shortly after irradiation and again after 3 weeks storage at 5°C for external colour, internal colour, soluble solids, pH, titratable acidity, vitamin C and eating quality. This chapter provides information on the major diseases of litchi in terms of their importance, symptoms, and management strategies. 1992. The predominant pathogen associated with fruit decay was Alternaria alternata (Fr.) Cephaleuros virescens. The various causes can be attribu«!d to two phenological stages of to 1.5 times higher in ‘Hass’ trees on the ‘Velvick’ 2. Kalyani, Ludhiana, pp 150-155, National Horticulture Board, Ministry of Agriculture, NHB (2015) Indian Horticulture Database 2014. The average loss at the wholesale market level in Delhi was 15.8% and 12.4% during 2012 and 2013, respectively. Removing all the fruits on a particular branch increased markedly the number of flowers and fruit set in the following year on the branch, and the larger the branch, the greater the effect of thinning. Pests were reared in the laboratory for identification and study of their biology. Drupelet set among genotypes ranged from 40% to 86% in 1993 and 39% to 78% in 1994. The following year some trees from A-tre-atments were left untreated to observe carry-over effects (C). Several fungi have been found to be associated with diseases Usually large water soaked lesions appear on the surface of fruits. Highest IWUE (57.1 g/m3) was observed in case of drip irrigation having 20 % ETc level and irrigation starting from 1 st April. Farm-level samples were collected immediately after harvest from farmers' orchards in the Muzaffarpur district of Bihar state. All Rights Reserved. Bacterial leaf blight of litchi (Litchi chinensis Sonn.) Investigation on diseases of litchi. 7. Farm-level samples were collected immediately after harvest from farmers' orchards in the Muzaffarpur district of Bihar state. Gu111613 to Gu111615). problem in warm tropics whereas poor fruit set is a problem of the subtropics. 2015.pdf. So far, only diseases caused by fungal pathogens have been reported. The spores enter the stomata, forming alga in the tissue of the tree. Mushroom root rot is the most deadly disease affecting the lychee tree. Diseases are one of the constraints on the production of litchi fruits. 5. It addresses disease management for a range of causal agents, including the leaf mite (Acerya litchi Keifer), leaf miner (Conopomorpha cramerella), fruit borers (Conopomorpha cramerella, Platypeplus aprobola Meyer and Dichocrosis sp. This is Cephaleuros virescens forms rust colored spots on the lychee leaves. Litchi (Litchi chinensis) pepper spot disease results in black spotting symptoms on litchi fruits.This disease was first observed on litchi cultivar Guiwei, in Guangzhou, China, in 2009, and then found widespread in other litchi‐growing regions of China. ‘Velvick’ Guatemalan seedling rootstock compared with the Leaf Blight: In nursery plants (Left) and In orchard on bearing tree (Right) Symptoms: A prominent disease in litchi nursery, also cause blight of panicles and developing fruits. Litchi is also grown in Tamil Nadu, West Bengal, Punjab, Assam and Tripura. Most genotypes had a higher percent set on early flowers compared to later ones. The highest mean loss (up to 20.5%) was observed at the retail level. Phyllosticta leaf spot is a disease which causes tan to black lesions and curling on lychee leaves. Three insect pests viz., red weevil (Apoderus blandus), semilooper (Anisodes illepidaria) and bagworm (Eumeta crameri) and one disease viz., leaf and twig blight (Colletotrichum gloeosporioides and Gloeosporium sp.) Also known as pepper spot disease, symptoms of anthracnose on lychee fruit include small tan black raised lesions and/or a white fuzzy mycelium coating on the fruit. Taperão, G.N. The increase in fruit abscission associated with pruning was not prevented by AVG application; and whole tree sprays did not increase yield on either pruned or unpruned trees. The spots are soft and spongy and germinate in the warm, summer months. Karen Curley has more than 18 years experience in health and nutrition, specializing in healthy food choices for families. The prolonged moisture stress between two irrigations under basin system resulted in lowest fruit length, smallest fruit diameter and higher fruit cracking percentage. Leaf blade length: 5 to 8 inches; leaflets are 2 to 3 inches. Viruses: Cherry leaf roll virus in walnut. None of the treatments influenced the tree cropping le-vel. The characteristics of the plant as height and pseudostem circumference, number of live leaves at flowering and harvesting, number of shoots, weight of bunch and hand, number of fruits and hands per bunch, fruit length and circumference, and the number of days from planting to flowering and harvest, were evaluated. (litchi), Sharma VK, Srivastava AK, Chohan JS (1972) A new host record for parasitic alga Cephaleuros Tai So lychees (Litchi chinensis Sonn.) They were Apoderous sp., a weeveil and Conopomorpha cramerella, a borer pest on fruits. Secondary fruit were picked when green but developing a red blush during the early- and late-ripening. Ten trees in an orchard were randomly selected and observations recorded in three branches having approximately 200 leaflets. factors influencing each of the stages of the reproductive cycle would help in Abstract —. Algal leaf spot proliferates in rainy conditions, spreading through the raindrops. Now approaching 500 hectares, plantings in south Florida have increased several fold in recent years. Excel India, Why This Works. Muzaffarnagar in Uttar Pradesh. - A REVIEW. Wholesale market samples were procured from the Delhi market, and retail samples from the Muzaffarpur and Delhi market. Insects and Diseases that Occurs in Litchi Plant and its Control! The Grand Naine clones (G.N. Keissler is a recent and economically important disease of litchi. The origin of the litchi is believed to be China and was introduced to India by the end of 17th century. 'Thornless Evergreen', and 'Chester Thornless', drupelet number was correlated with fruit weight, although the relationship in 'Chester Thornless' was not as strong as the others. The greatest flowering occurred in stems that were 15 to 25 weeks of age in 'Mauritius', compared to 20 to 30 weeks for 'Brewster'. Rootstock studies conducted on ‘Hass’ avocado found that rootstock Abstract and Figures India is one of the leading litchi (Litchi chinensis Sonn.) 84-89. shoot extension and internode growth, whereas B-treatments re-duced shoot extension and internode length, simultaneo-usly increasing flower bud density, particularly by 500 mg ProCa l -1 . Weeds 3.1 Panicum repens 3.2 Trainthema monogynae PEST MONITORING A. Leaf Roller (Platypeplus Aprobola Meyer): The new flushes are attacked by this pest through out the litchi growing area. 1, pp. Although several fungi have been reported to occur on litchi but none of them causes any major disease of economic importance. The studies revealed the damaging potential and period of occurrence of these pests and disease in the major litchi growing areas. Gleosporium sp. Infestation of A. blandus, D. aprobola, and E. crameri drastically affected the growth of tree whereas P. illepidaria damaged the September fl ush that bears panicle in the ensuing season. Some of the pathogens infect leaves, flowers, and fruit, and a few others are associated with tree decline and tree deaths. Litchi (Litchi chinensis, også stavet lychee eller laichi), er det eneste medlemmet av gruppen Litchi i såpebærfamilien Sapindaceae. Field surveys carried out in litchi growing areas of Bihar during 2009-10 revealed the occurrence of two insect species in severe form which were hither to either unnoticed or of minor importance. diene concentrations were around 3 times higher in ‘Velvick’ than National Horticulture Board, Ministry of Agriculture, Government of India, Gurgaon, India. Studies were conducted to assess the occurrence and level of damage by these pests and diseases. However, the results allowed to recommend the following clones: N. IAC Abóbora Verde and G.N. In India, litchi is grown mainly in the eastern part of the country and Bihar Province contributes nearly 74% of the total production. ‘Duke 6’ Mexican seedling rootstock. Peak infestation of D. aprobola was during July-February. The mean total loss in the supply chain of litchi ranged from 35.3% to 43.8%. Back To TOC. Early planting caused an increase in yield size and weight of fruits as well as in the percentage of fruits heavier than 900 g. Delayed planting caused increase only in the percentage of fruits ranging from 600 to 900 in weight. It is native to China but grows in all tropical areas of the world. January caused a 50-day decrease in the natural crop cycle. Studies indicated that the average loss (fruits discarded at sorting) apparent at the farm level during 2012 and 2013 was 30.4% and 25.8%, respectively. Due to continuous sucking of sap, leaf tissues become aggravated and formed erineum. Farzana Yasmin , Ismail Hossain. macadamia and if it could be used to mitigate the effect of pruning on abscission. anthracnose was significantly lower on ‘Hass’ grafted to Between July 2011 to June 2012, some new threats of pests and diseases were observed during scouting and fixed plot surveys of litchi orchards in Bihar that were hitherto either unnoticed or of minor importance. l The spray of 5:5:50 Bordeaux mixture during autumn (September-October) and Spring (February-March) at 15 days interval depending upon degree of infestation. severity and skin N/Ca ratio was also evident. Chemical control of algal rust of litchi caused by Cephaleuros virescens, Gupta JH (1992) Chemical control of algal rust of litchi caused by Cephaleuros virescens. by post harvest technology. Gamma irradiation of lychees at 75 or 300 Gy may be used for disinfestation purposes with no adverse effects on fruit quality. The spores enter the stomata, forming alga in the tissue of the tree. In 'Boysen', 'Marion'. The mean fruit weight loss during transport to Delhi was 9.42% and 7.07% during 2012 and 2013, respectively. To read the full-text of this research, you can request a copy directly from the authors. Fruits were harvested from February through April 1983. the reproductive cycle viz., floral initiation and flowering and fruit set. Young growing tree of less than five years age were devastated. This book offers a comprehensive compilation of biotic and abiotic factors that affect lychee production and commercialization. Real-time data on losses and quality parameters of fruits were recorded by transporting litchi from Muzaffarpur to Delhi (distance 1000 km) by truck. Algal leaf spot is also known as green scurf or red leaf spot. De Villiers, E. A. Similarly a change in disease complex also has been observed. You can request the full-text of this chapter directly from the authors on ResearchGate. Fruits 32, 269-73. Wholesale market samples were procured from the Delhi market, and retail samples from the Muzaffarpur and Delhi market. The ‘leaf and twig blight’ disease was prevelent from the beginning of August to the end of February. of various, Litchi (Litchi chinensis Som.) The incidence of leaf and twig blight disease was from 28.1 to 66.3%. The disease manifested itself from the beginning of August to the end of February. It was found that the most desirable ratio of fruit to leaves for the current year's crop and the following year's fruiting was 20 to 25 leaves per fruit for Satsuma orange on trifoliate orange rootstock, and 15 to 20 leaves per fruit for the one on Yuzu (Citrus junos) rootstock. CFB packaging significantly reduced various losses, thus indicating its effectiveness in its current use in non-refrigerated trucks for transport. Litchi (Litchi chinensis Sonn.) The total yield of the two succeeding years was increased and annual amount of crop obtained by the fruit thinning was nearly equal in the two years. The incidence of leaf and twig blight disease was from 28.1 to 66.3%. New threats of insect pests and disease in litchi (Litchi chinensis Sonn.) However, the appropriate time of fruit thinning for Satsuma orange seems to be the early part of August in Okitsu, as physiological fruit dropping has been over by the end of July. Effect of fruit stage based irrigation scheduling on yield, quality and irrigation water use efficie... FLOWERING AND FRUIT SET IN LYCHEE {LITCHI CHINENSIS (GAERTN.) Twig blight symptoms in young orchard were aggravated by leaf feeding insect pest complex. is a subtropical evergreen tree belonging to the family Sapindaceae. Another such disease is 'litchi sudden death disease'. The objective of survey through roving surveys is to monitor the initial development of pest and disease in the endemic areas. Direct and apparent residual effects of prohexadione - calcium applied to young cropping sweet cherr... Phenological growth stages of lychee (Litchi chinensis Sonn.) virescens Kunze. Deficit irrigation showed great potential to increase the irrigation water use efficiency of litchi production without affecting the fruit quality and with slight deviation in potential yield. The light brown spots of Gloeosporium leaf blight merge together, eventually making the whole leaf look scorched brown, before defoliation occurs. The decrease in the yield of the current year by the fruit thinning was only slight, because of the increase in size of the remaining fruits. Fruit rots and their control by post harvest technology. Moreover, a P. litchi isolate from litchi caused symptoms of leaf blight on young longan seedlings. Drip irrigation system recorded highest fruit weight (22.6 g) at 60 % ETc and irrigation starting from 1 st March. Emerging pests and diseases of litchi (Litchi chinensis Sonn.). The occurrence of A. illepidaria and E. crameri is being reported on litchi for the first time from India. Detailed experiments on individual branches were conducted to investigate the impact of flush age on flowering over three seasons. This video is showing how to grow litchi and care litchi plant ? were irradiated at 0, 75 or 300 Gy in replicated experiments using a 60Co source. The symptoms of damage were described. Lychee Diseases Diseases of lychee tree include anthracnose, root rot and red algae. The lychee leaves eventually turn yellow and the tree dies. "Leaf Blight of Litchi in Nurseries of Northern Region of Bangladesh and Its Management", International Journal of Biotech Trends and Technology (IJBTT), V4(3):1-10 Jul - Sep 2014, Published by Seventh Sense Research Group. Commercial cultivars were chosen to represent types (trailing, erect, and semi-erect) of blackberries grow n in the United States. 5. Post anthesis applications to racemes increased set only slightly and the effects of low concentrations in 2007 were similar to those of high concentrations in 2008. The total soluble solids, respiration and ethylene evolution in litchi fruits were found to increase after transport, whereas acidity and colour parameters (L*, a* and b* values) significantly decreased over time. Leaf margin: entire. This virus reduces gradually the vigor of the tree, the leaves are yellow and wilt, and the tree losses prematurely its leaves. Also, the sprouts are frail and will not develop normally, and in the bark can appear cracks or even holes. and shoot development, inflorescence emergence, flowering, fruit development, and fruit maturity. A tough fungal growth known as mycelium, grows in between the wood of the lychee tree and the bark. Mushroom root rot usually infests lychee trees where oak trees were previously planted. collected from the states of São Paulo, Santa Catarina and Bahia, were evaluated at the Station 54-P of the Thelo Agricultural Production (Plena Group), in the Jaíba Project, Stage 1, in the city of Matias Cardoso-MG. As litchi has great export potential, it is necessary to know about the diseases of litchi and approaches for their management. The weevil was brownish red in colour, about 5-7 mm in length and with a strong rostrum, causing heavy damage to new flush. The infected tree becomes susceptible to fungus because of its weakened condition from leaf spot. Drupelets and pistils per fruit were counted to calculate percent set. The average loss at the wholesale market level in Delhi was 15.8% and 12.4% during 2012 and 2013, respectively. Anthracnose – This fungal disease is caused by the fungal pathogen Colletotrichum loeosporioides. from trees grafted to different rootstocks. He goes on to say that the fungus kills lychee trees by forming mushrooms around the trunk of the tree and in the roots. from 1 st February (pre flowering), 1 st March (start of fruiting) and 1 st April (start of fruit development stage). A significant The common name for Litchi chinensis is the lychee tree. is a juicy fruit belonging to the Sapindaceae family and is one of the most important evergreen fruit trees. The common name for Litchi chinensis is the lychee tree. According to Julia F. Morton, past president of the Florida State Horticultural Society, “the lychee tree is the most renowned of a group of edible fruits of the soapberry family, Sapindaceae.” Morton also states that lychee trees are fungi resistant but are sometimes afflicted by three types of disease. The earlier the fruits were thinned (including flower thinning), the more the effect was, though the thinning even in as late as mid-November showed some effect. Some pathogens also affect multiple phenophases of this fruit crop. 1. Racemes on ‘849’ trees that had been planted in 2002 were sprayed either pre or post anthesis with AVG at concentrations of 0, 30, 60 or 90 ppm in 2007, and 0, 200, 400 or 600 ppm in 2008.

Butani, D. K. 1977. There is another serious leaf spot of litchi incited by Microdiplodia litchi Pathak and Desai that has been recorded at Udaipur Therefore, for field scouting fanners should be mobilized to observe the pest and disease occurrence at the Deficit water application under drip system resulted in higher reducing sugar content (7.5 %) of litchi fruits. Diseases 2.1 Dieback 3. In this Gardenerdy article, we shall have a look at a list of common plant diseases that are encountered in gardens and farms. P. litchii was reisolated from the infected longan tissues. This study presents codes and detailed crop-specific descriptions for the growth stages of the lychee tree in southern China. the first record of such an effect for avocado. Other important areas oflitchi are Dehradun, Saharanpur and, A field experiment was conducted to study the efficacy of deficit irrigation on litchi crop under two deficit irrigation (DI) strategies viz. at National Research Centre for Litchi (NRCL) that were hitherto either unnoticed or of minor importance. Mushroom root rot is the most deadly disease affecting the lychee tree. Keissler is a recent and economically important disease of litchi. considered as a serious disease in the nurseries especially in Northern region of Bangladesh. They indirectly reduce yield by debilitating the tree and directly reduce the yield or quality of fruit before and after harvest. 2. Keissler. Leaf venation: pinnate. Williams, G.N. Litchi is also grown in Tamil Nadu, West Bengal, Punjab, Assam and Tripura. The symptoms starts from tip of the leaf as light brown to dark brown necrosis that advances towards both the margins of the leaf leading to complete necrosis of the affected leaves that dries up subsequently. CFB packaging significantly reduced various losses, thus indicating its effectiveness in its current use in non-refrigerated trucks for transport. Survey was conducted on leaf blight of litchi in 7 cultivating litchi varieties in the country. A. blandus was prevalent round the year except during extreme cool and hot weather months whereas P. illepidaria was prevalent from September-November and E. crameri during November-February. is a juicy fruit belonging to the Sapindaceae family and is one of the most important evergreen fruit trees. Drip irrigation system recorded the highest, Low productivity is the main hindrance of acceptance of lychee {Litchi chinensis (Gaertn.) Canadian Journal of Plant Pathology: Vol. Main diseases. Leaf, panicle and fruit blight of litchi (Litchi chinensis) caused by Alternaria alternata in Bihar state, India. I, Resposta do abacaxizeiro 'Pérola' a cinco épocas de plantio. All rights reserved. As time goes on, the mycelium turns mushy, forming the deadly mushrooms. Journal of the American Society for Horticultural Science. Pre anthesis application had a similar effect to post anthesis application in 2007 but decreased initial fruit set relative to post anthesis application and the control in 2008. The ribosomal internal transcribed spacer (ITS) sequence confirmed that the longan isolate Tari 20250 (GenBank Accession No. During germination, spores are produced and invade the stomata, the pores in the leaf’s surface. Initially the disease symptoms are perceptible on injured portion of the fruits. During May and June of 2012 and 2013, a study was conducted to assess losses at the farm, wholesale and retail levels in the supply chain of litchi in India. Curley is also an avid gardener, home renovator, Collie breeder, dog groomer and dog trainer. Fruit fly. Sydowia A proper understanding susceptibility were related to significant differences in concentrations of Increases in the number of flowers and yield were obtained in the following year. Leaf type and persistence: broadleaf evergreen, evergreen. Most are the result of improper watering (either too much or too little), or excessive use of fertilizer. Stem age, winter temperature and flowering of lychee in South Florida, Percent Drupelet Set Varies among Blackberry Genotypes, Studies on the control of alternate bearing in citrus. Cool temperatures are known to induce flowering, but other factors such, Twenty-one genotypes of blackberry (Rubus L. subgenus Rubus Watson) were evaluated for percent drupelet set in 1993 and eleven genotypes were evaluated in 1994. The fungus usually manifests itself from early to late summer. The highest mean loss (up to 20.5%) was observed at the retail level. Studies indicated that the average loss (fruits discarded at sorting) apparent at the farm level during 2012 and 2013 was 30.4% and 25.8%, respectively. caused by Alternaria alternata (Fr.) The leaf blight appears as tan spots on the leaves. Curr Sci 31:293. It addresses disease management for a range of causal agents, including the leaf mite (Acerya litchi Keifer), leaf miner (Conopomorpha cramerella), fruit borers (Conopomorpha cramerella, Platypeplus aprobola Meyer and Dichocrosis sp. Great similarity among the clone characteristics was observed. The mean total loss in the supply chain of litchi ranged from 35.3% to 43.8%. http://nhb.gov.in/area-pro/NHB_Database_ 1-Leaf spots 2-Red rust 17. SC-074) and Nanicão (N. IAC Abóbora Verde, N. Rossete, N. SC-0008 and N. SC-063), Macadamia, a subtropical evergreen tree, flowers profusely but sheds more than 98% of flowers and fruitlets within 10 weeks of anthesis. A few mycoflora has been consistently isolated associated with fruit drop. It addresses disease management for a range of causal agents, including the leaf mite (Acerya litchi Keifer), leaf miner (Conopomorpha cramerella), fruit borers (Conopomorpha cramerella, Platypeplus aprobola Meyer and Dichocrosis sp. Prevalence of some threatening pests and disease of Litchi (Litchi chinensis Sonn.) The mushrooms grow into the healthy roots, causing them to rot. Curr Sci 31:293, Investigation on diseases of litchi. During May and June of 2012 and 2013, a study was conducted to assess losses at the farm, wholesale and retail levels in the supply chain of litchi in India.
