In: Diagnostic Criteria for Plants and Soils, Chapman, H.D. By the application of these strategies the anthracnose problem can be managed properly with better economic benefits and small risk of health hazard effects. Anthracnose can survive on … Changes in the constituents of guava fruits at different developmental stages. Integration of various management practices has brought success in some crops (Raut, 1990; Singh et al., 1990; Adisa, 1985). Each type was isolated from peach, apple, and pecan. Prevalence and control of guava fruit anthracnose. Motiramni, Y.P. They found young immature guava fruits were free from infection while mature fruits were infected readily and this difference might be due to concentration of potassium ion at different developmental stages have been found.

The Second Edition of this bestseller brings together basic plant pathology methods published in diverse and often abstract publications. Role of potassium in the pathogenesis of Colletotrichum gloeosporioides, in guava fruits. The post harvest diseases recorded during the survey from Keywords: Antagonistic fungi, anthracnose, guava, disease management, PGPR INTRODUCTION Guava (Psidium guajava L.) an important member of family Myrtaceae L. is assumed to be originated from Southern part of Mexico. It has slander like trunk with smooth red green bark. did not show any clear pattern of hyphal interaction and inhibited the growth about 90.90%. The purpose of the present study was to explore the possibility of integration of various approaches for control of guava anthracnose. Guava trees are seriously damaged by the citrus flat mite brevipa1pus californicus. Bayletan at 20 ppm, Daconil at 20 ppm, Ridomil Gold at 60 ppm showed 29 mm, 37.3 mm and 42.6mm growth of, Overall view of colony growth of C. gloeosporioides in all tested fungicides. Gypsum alone had no effect on development of disease. Urea, gypsum, cowdung+SOC and SOC produced highest (4.8-6.8%) surface area infection among all other treatments with SOC supporting the highest. The highest incidence and severity of postharvest diseases of the fruits were recorded in September, March, August and March, whereas the lowest incidence and severity were, Mango (Mangifera indica) is the most important fruit crop in the world as well as in Pakistan, called the king of fruits. Probably, the management approaches worked well under such above mentioned conditions. As Aspergillus species except A. fumigatus caused more than 50% of inhibition similar results were obtained by Pandey et al. But this has not been tried in case of guava anthracnose. As condições ótimas para a infecção do fruto foram sob temperatura de 26 e 27ºC, para 'Kumagai' e de 25 e 26ºC, para 'Pedro Sato', com 24 horas de molhamento. Many commercial producers think to give up the cultivation of guava owing to a great loss by the disease. Gray isolates produced gray colonies on PDA, grew slightly or not at all on benomyl-amended medium, had conidia with rounded ends, and had similar RFLP patterns that were distinct from pink isolates. Efficacy of different fungicidal chemistries (Topsin-M, Antracol, Captan, Benlate and Bavistin) was evaluated in vitro by the poison food technique against Colletotrichum gloeosporiodes. Under humid conditions, the necrotic lesions become covered with … These results are very much promising from the view point of non-chemical control of guava fruit anthracnose. Cowdung+MOC (ghani), TSP, Urea amended plants suffered from moderate infection of fruit anthracnose. Colletotrichum gloeosporiodes was isolated with maximum infestation frequency (61.66 %). Disease severity was low during the experimental period, perhaps because of low inoculum pressure or unfavorable weather. Guava. But this has not been tried in case of guava anthracnose. Foliar spray: No disease observed in tilt sprayed plants. Chohan, 1970. (2002). The fungus develops from the … It contains vitamins A, B, C plus some minerals and good for health (Baradi, 1975). The guava plant starts commercial yield from 3 rd year onward under good management practices. Aspergillus flavus and Pseudomonas florescence were found to be the most effective treatments among fungi and PGPR evaluated respectively in inhibiting the colony growth of C. gloeosporioides. Soil solarization. Aliette was the most effective at all concentrations followed by mancozeb which was effective at 20 and 40 ppm concentrations but less at 60 ppm. 147-152. Keywords: Antagonistic fungi, anthracnose, guava, disease management, PGPR INTRODUCTION Guava (Psidium guajava L.) an important member of family Myrtaceae L. is assumed to be originated from Southern part of Mexico. These investigations provide fresh information on the current status of mango anthracnose on inflorescence in orchards of mango zone in Pakistan, regarding chemical control against Colletotrichum gloeosporiodes under in vitro conditions and serve as a guide for the future management strategy against this holistic disease of mango. Manures also supply all of the essential major and minor elements. The treatments with their doses are shown in Table 1. Currently there are only three fungicides registered for use on avocado. Management Ensure trees receive adequate fertilization, irrigation and and are properly pruned to avoid stress on the plants and promote air circulation through the canopy; periodic applications of a copper based fungicide is usually enough to control the disease.
