A BIO-PESTICIDE BASED ON NUCLEOPOLYHEDROVIRUS FOR THE MANAGEMENT OF TEAK PEST HYBLAEA PUERA

摘要

This invention relates to the production of a wettable powder biopesticide fonnulation containing a naturally occurring microorganism, the nucleopolyhedrovirus of the teak defoliator, Hyblaea puera as the active ingredient and talc as carrier, activated carbon as protectant against deterioration by ultra violet rays in sunlight and polyvinyl alcohol as dispersing agent, all mixed in a specific proportion, which is effective in controlling the teak defoliator, Hyblaea puera, which can withstand the damaging effect of ultraviolet rays in sunlight during field application and which has a storage life with retention of over fifty percent infectivity upto eighteen months when stored, in dark at room temperature of about 28°C +- 4°C.
