Studies on the bioefficacy of the botanical biocide formulations from seven different aromatic and medicinal herbs against coconut eriophyid mite, revealed that herbal formulations were significantly effective. Highest reduction in mite population was observed after fourth application in West Bengal (88.97%), followed by Karnataka (83.89%) state field trials. The highest numbers of mites per sq.cm of counting dish were observed on three month old nuts both in treated as well as untreated samples over all the trial farms.
