FIELD APPLICATION OF STEINERNEMA-FELTIAE IN THE FORM OF BAITS AGAINSTTHE GREASY CUTWORM AGROTIS-IPSILON IN AN OKRA FIELD IN EGYPT

Field tests were conducted to determine the effectiveness of wheat bra n baits based on Steinernema feltiae compared to the pathogen Bacillus thuringiensis and the organophosphorus compound hostathion against Ag rotis ipsilon infesting Okra, Hibiscus esculentis cultivations. Signif icant larval reduction was observed in all treated plots after applica tion with a significant increase in the yield compared to the control plots. The yield was significantly affected by varying the number of I JS of the entomogenous nematode in the baits.
