Abstract:
Coriander aphid Hyadaphis coriandri (DAS) is one of the major constraints in the production of coriander. In order to find out the effective biopesticides and fungicides against Hyadaphis coriandri experiment was carried out in field condition. The relative efficacies of different combinations of biopesticides and pesticides were tested in different concentration. Among the different combinations of treatments, Acetamiprid + Propiconazole (first spray) + Carbendazim (second spray) was the most effective with mean 1.48 AI after first spray and 1.29 AI after second spray over untreated control 2.26 AI (first spray) and 2.79 AI (second spray). The highest seed yield kg/ha (1149.00), gross income Rs 103,410 ha^-1, net income Rs 59394 ha^-1 and B:C ratio 2.34:1 was obtained in the treatments combination of Acetamiprid + Propiconazole (first spray) + Carbendazim (second spray) closely followed by Lecanicillium lecanii + Propiconazole (first spray) + Carbendazim (second spray).
