O. ii ABSTRACT Cashew (Anacardium occidentale L.) is an important export crop in a number of tropical countries and is the main cash crop and the leading source of income for over 30 Though cashew is not Cashew, a perennial tree well known as „poor man‟s crop‟ is a source of highly priced cashew nuts. The potential for high epidemics in each location or crop season was expressed by the emi value The screening and breeding of cashew genotypes for resistance to the disease and others including the cashew stem girdler (Analeptes trifaciata) insect pest is a feat to be achieved. 6 0 obj Previously cashew powdery mildew was known to be the main disease of cashew. The fungus penetrates into the deeper tissues and causes the death of the shoots from the tip downwards and hence the name dieback. Investigations on the failure of fruit setting in bearing trees in plantation holdings in Trengganu and Pahang revealed that the major problems of the cashew crop were not agronomical but rather pathological and entomological in nature. India being the leading producer, consumer and second largest exporter of cashew in the world, has a prime position in cashew trade in the world market.Cashew, Industry, But the %PDF-1.5 I = b (1-e-as) (P***<0.001) (1) In this function, I stands for incidence, S for severity,b for estimated maximum incidence (emi) anda stands for estimated initial disease incidence (eii).
