Abstract | ||||
Afield experiment was conducted of DirabNegm, district, sharkia governorate, Egypt, during 2019 growing season to evaluate the effect of four bioinsecticides namely propargite (skanmite, 73%EC), abamectin (spiner10%sc), thiamethoxam 15.24%+ abamectin 3.23%(Agreflex 18.6% sc.) and B.T (protecto 9.4%wp) against the green peach aphid myzuspersicae (sulzer) attacking potato and tomato plants, using different doses.Summarized results revealed that m Agroflex recorded annual or seasonal average effects expressed as highest reduction percentages on aphid in festation (74.67%) followed by skanmite (73.65%), protecto (73.51%) and spiner (69.59% against aphid infesting potato plants, the same order of the effiviency of the tested bioinsecticides was noticed in tomato plants except aswitch in position between skanmite and protecto. | ||||
