Fusarium spp., one of the most important pathogens which causes wilt disease of guava (P. guajava L.) is a major threat to guava cultivation (Misra and Pandey, 1996, Misra, 2006). The name Fusarium oxysporum f. psidii is proposed for the causal organism. This cultivar is being used in breeding programme to develop mango varieties resistant I tolerant to malformation at the Central Institute for Subtropical Horticulture, Lucknow. Wilt is a pernicious disease of guava in India. 1968. Guava wilt disease is characterised by yellow to reddish colouration leaves and their and subsequent premature defoliation. CAUSAL ORGANISM Anthracnose is caused by Gloeosporium psidii,or … Several pathogenic fungi, nematodes and bacteria were found associated with the wilted trees of guava around the world; however, Fusarium spp. Fruit Canker (Restalotia psidii Pat.) This presentatation was presented by Bipin karki,BIjendra pradhan, Bivek Gyawali and Dorna Giri at IAAS Paklihawa. In South Africa,Septofusidiumsp. Communities and local institutions organized to participate in decision-making processes regarding the conservation and sustainable use of tropical fruit tree genetic resources Pathogenicity tests were performed in pot experiments to confirm the causal agent of the disease. Since, it is highly remunerative crop; disease is extremely important. WELCoME Some chemical changes in guava fruits infected by. Methodologies and good practices that use tropical fruit tree genetic resources are identified and/or developed The name Fusarium oxysporum f. psidii is proposed for the causal organism.
