Abstract

In present trial combination of propargite 50% + bifenthrin 5% SE, was evaluated against Tetranychus urticae. The results indicated that propargite 50% + bifenthrin 5% SE @ 1,150 ml/ha recorded the highest per cent reduction of mites over the control (91.31%) followed by lower doses of the same product tested. The combination of two chemicals was more effective than the individual chemicals tested. The effectiveness of this product also gave maximum fruit yield (9.53 t/ha) with C: B ratio as 1: 6.26.
