Abstract

Severity of inflorescence dieback in three cashew accessions varied significantly with treatment types, least dieback severity was recorded in Brazilian medium accession treated with aqueous extract of Carica papaya leaf. Cashew accessions showed no significant difference in severity of inflorescence dieback when treated with C. papaya, carbendazim, Ageratum conyzoides, carbendazim and C. papaya combination, carbendazim and A. conyzoidescombination in one season. Significant differences were recorded in number of nut yield in Brazilian medium accession treated with carbendazim and Indian large accession treated with mancozeb and A. conyzoides combination. Highest number of nut was recorded in Brazilian medium accessions treated with carbendazim and A. conyzoides combination but not significantly different from carbendazim while some other accessions showed no significant difference in number of nuts. The best yield of cashew was recorded in Brazilian large accession treated with mancozeb with C. odoratacombination but the yield response of Indian large accession to integrated disease management was least among the three accessions trials. The integrated disease management systems generally improve yield of cashew accessions.
