Leaf blight Symptoms: A prominent disease in litchi nursery, also cause blight of panicles and developing fruits. Pineapple slips weighing 120 g to 200 g each were planted on the first fortnights of September through December 1981 and January 1982. 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. Similarly a change in disease complex also has been observed. anthracnose was significantly lower on ‘Hass’ grafted to Leaf diene concentrations were up Drip irrigation system recorded the highest, Low productivity is the main hindrance of acceptance of lychee {Litchi chinensis (Gaertn.) Magário, G.N. macadamia and if it could be used to mitigate the effect of pruning on abscission. Moreover, a P. litchi isolate from litchi caused symptoms of leaf blight on young longan seedlings. 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 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. Flowering induction occurred every first Winter after planting. The infected tree becomes susceptible to fungus because of its weakened condition from leaf spot. Pests were reared in the laboratory for identification and study of their biology. Leaf, panicle and fruit blight of litchi (Litchi chinensis) caused by Alternaria alternata in Bihar state, India. The predominant pathogen associated with fruit decay was Alternaria alternata (Fr.) The following year some trees from A-tre-atments were left untreated to observe carry-over effects (C). Leaf type: odd-pinnately compound; made up of 4-8 leaflets. Although several fungi have been reported to occur on litchi but none of them causes any major disease of economic importance. 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. Curley is also an avid gardener, home renovator, Collie breeder, dog groomer and dog trainer. The lychee leaves eventually turn yellow and the tree dies. Wholesale market samples were procured from the Delhi market, and retail samples from the Muzaffarpur and Delhi market. Having it on a daily basis in any form, including litchi juice, can actually help prevent the occurrence of this fatal disease. Copyright Leaf Group Ltd. // Leaf Group Lifestyle. The mean fruit weight loss during transport to Delhi was 9.42% and 7.07% during 2012 and 2013, respectively. Litchi is also grown in Tamil Nadu, West Bengal, Punjab, Assam and Tripura. Changes in fruit quality parameters after harvest and the effectiveness of an improved corrugated fibre board (CFB) box versus conventional wooden box packaging to minimize postharvest losses were also studied. 1992. 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. Most genotypes had a higher percent set on early flowers compared to later ones. The average loss at the wholesale market level in Delhi was 15.8% and 12.4% during 2012 and 2013, respectively. Keissler is a recent and economically important disease of litchi. Even when the number of flowers was increased by the fruit thinning in the previous year, the number of shoots and their growth were not decreased, but rather increased in most cases. Fruits were harvested from February through April 1983. The spots are soft and spongy and germinate in the warm, summer months. Algal leaf spot proliferates in rainy conditions, spreading through the raindrops. In ungrafted nursery stock trees, This chapter provides information on the major diseases of litchi in terms of their importance, symptoms, and management strategies. This premature fruit abscission is accentuated when trees are hedged in spring, as is commonly practiced in Australian orchards.

Gu111613 to Gu111615). ‘Duke 6’ leaves. The occurrence of A. illepidaria and E. crameri is being reported on litchi for the first time from India. Due to continuous sucking of sap, leaf tissues become aggravated and formed erineum. Irradiation had virtually no effect on any of the physical, chemical or organoleptic parameters investigated. 84-89. Weeds 3.1 Panicum repens 3.2 Trainthema monogynae PEST MONITORING A. They indirectly reduce yield by debilitating the tree and directly reduce the yield or quality of fruit before and after harvest. Taperão, G.N. 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. 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. Some post harvest rots commonly occur after the injury on fruits causing major economic loss in marketing and export offruits. Cephaleuros virescens forms rust colored spots on the lychee leaves.

All Rights Reserved. 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 . Diseases are one of the constraints on the production of litchi fruits. 3. Mushroom root rot usually infests lychee trees where oak trees were previously planted. The lychee leaves eventually turn yellow and the tree dies. Sydowia The origin of the litchi is believed to be China and was introduced to India by the end of 17th century. The severity and incidence of Sci Cult 38:39-40, Two new leaf spot diseases of Nephelium litchi Camb, Prasad SS (1962) Two new leaf spot diseases of Nephelium litchi Camb. Bacterial leaf blight of litchi (Litchi chinensis Sonn.) Litchi Mite Aceria litchi: Both nymphs and adults of mite damage the leaves, inflorescence and developing fruits through sucking the cell sap. Drupelets and pistils per fruit were counted to calculate percent set. It is unclear what factors limit drupelet set in the genotypes studied. The highest mean loss (up to 20.5%) was observed at the retail level. Fruit rots and their control by post harvest technology, Prasad SS, Bilgrami RS (1973) Investigation on diseases of litchi. Farzana Yasmin , Ismail Hossain. Litchi (Litchi chinensis Sonn.) combination also had a significantly lower leaf N concentration, a Gleosporium sp. The mean fruit weight loss during transport to Delhi was 9.42% and 7.07% during 2012 and 2013, respectively. in English from the University of Massachusetts. Algal leaf spot is also known as green scurf or red leaf spot. 1. season. National Horticulture Board, Ministry of Agriculture, Government of India, Gurgaon, India. Canadian Journal of Plant Pathology: Vol. In addition, 41 secondary growth stages are described. 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.
