Field Evaluation of Some Eco-Friendly Formulations against Strawberry White grubs in Egypt
Ahmed Mohamed Ezzat Abd El-Salam
Field evaluation of Imidacloprid and bio-formulations was carried out with irrigation water against the white grubs, Pentodon algerinum at El-Behera Governorate, Egypt. The results revealed that Imidacloprid was the highest effective followed by bio-catch and nimbecidine was the lowest effective .The first application revealed that the effective all formulations were did not significantly after the 1st week from application. While, the 2nd week from application, Imidacloprid, Metarhizium anisopliae formulation and Nimbecidine achieved 78.0, 75.0 and 67.2 % reduction in live white grub larvae, respectively. The second application clearly confirmed the efficiency of these compounds. Although, the biocompounds are slower effective than the chemical insecticide against the white grubs but these are the safest for humans and the environment. I think that used another ways with biocompounds through an integrated pest program that would be lead to the better control against the white grubs.
