Abstract

An experiment was conducted to evaluate the bioefficacy of Lannate against leaf defoliators of soybean. Soybean variety PK 416 was sown in the plots (4.5x3 m2) with 45x5 cm spacing. Eight treatments i.e. Lannate 40 SP @ 200, 250, 300, 350, 450, 800 g ai/ha, Triazophos @ 0.8 l/ha along with untreated control were given as two sprays given at 68 and 82 days after sowing. Results indicate that spray of Lannate 40 SP @200, 250, 300, 350, 400, 800g ai/ha along with Triazophos @ 0.8l/ha and untreated control was done at 68 days and 82 days of sowing in crop. Lannate 40SP @ 400g ai/ha gave effective control of Tobacco caterpillar and green semilooper and significantly gave higher yield over untreated control. Triazophos@0.8l/ha proved least effective. No phototoxic symptoms were observed on any of the treatments.
