| Abstract | ||
| Laboratory study was conducted to evaluate the toxic effect for a number of modern chemical insecticides were Calpso480SC (Thiacloprid) and Confidor200SL (Imidacloprid) and Procliam (Emamectin benzoate) and) Spintor24SC( spinosad) with three concentrations included (Average Field= AF) and (AF- 50%) and (AF+ 50%) in the growth and reproduction of two biological control fungal Beauveria bassiana and Trichoderma harzianum and biological control bacterial Bacillus thuringiensis var kurstak. The results showed differences of inhibitory effects of tested insecticides in the growth and conidia production of Beauveria bassiana , Spintor was less inhibiting and reduction for conidia. (22%) ,while not causing inhibition of the vegetative growth of the fungus (0.00%) at the concentration (AF- 50%) , results showed that all insecticides were compatible with Beauveria bassiana at three concentrations of the insecticides except Confidor, which showed moderate toxicity at the concentration (AF+ 50%).While the results showed tested chemical insecticides did not have inhibitory effect on the vegetative growth of the fungus T.harzianum at three concentrations except calpso at the concentration (AF+ 50%) which showed inhibition in the vegetation growth by reducing percentages for fungi colony reached 85.94%, while insecticides showed differences in inhibitory effect for conidia by reduction ranged from 07.09 to 01.28% at the concentration(AF- 50%) , all pesticides were compatible with the fungus T.harzianum at concentrations (AF) and (AF- 50%), while showed the concentration (AF+ 50%) of calpso ,proclaim and spintor toxic effect for T.harzianum .The results showed that the pesticide Spintor of more tested pesticides compatibility with B. thuringiensis var kurstak at the concentration(AF- 50%) . | ||
