THE EFFICIENCY OF SALICYLIC ACID WITH DELTAMETHRIN AND FLUPYRADIFURONE INSECTICIDES FOR THE CONTROL OF MYZUS PERSICA (SULZER) ON BROCCOLI

Abstract

The results of the study showed the possibility of using Salicylic acid in interference with Deltamethrin and Flupyradifurone in reducing the population density of green peach aphid insect Myzus persica on the broccoli plant Brassica oleracea var. italica, where the Salicylic acid showed an effective role in controlling on the insect with the concentration of 200 mg.L-1 and reducing the population density of the insect to 2.04 and 1.86 insect leaf-1 after 7 days of completing the first and second sprays, respectively, The both pesticides Deltamethrin and Flupyradifurone contributed in reducing the average of the population density of the insect from 7.58 insect leaf-1 in control treatment to 0.52 and 0.45 insect leaf-1, respectively.The interference of the Salicylic acid at concentration of 200 mg.L-1 with Deltamethrin and Flupyradifurone had a significant effect on controlling on the insect, where the population density of the insect reduced to 0.8 and 0.5 insect leaf-1, respectively after 3 days of the first spray compared to 10.76 insect leaf-1 in the control treatment. The effect of Salicylic acid and the two pesticides Deltamethrin and Flupyradifurone and their interference among them were also reflected positively on some of the chemical characteristics on the leaves broccoli plant, that were represented by the ratio of Protein and the concentration of enzyme of Peroxides compared to the control treatment.
