Abstract

The field trials to evaluate the bio-efficacy of different doses of Pyriproxyfen 8% + Clothianidin 3.5 SE as foliar spray against sucking pests of cotton were conducted at Agricultural Research Station-Borwat Farm, Banswara (Rajasthan) during Kharif 2016 and 2017. The results of the investigation revealed that the ready mix molecule of Pyriproxyfen 8% + Clothianidin 3.5 SE @ 1500 ml and 1250 ml ha-1 were very effective in providing protection against sucking pests of cotton viz. whiteflies, jassids and thrips with highest mean seed cotton yield (1986 & 1831 kg ha-1, respectively) and were statistically at par. The next best treatments were Diafenthiuron 50 WP @ 600 g ha-1, followed by Clothianidin 50 WDG @ 50 g ha-1. None of the treatments showed any symptoms of phytotoxicity.

Conclusion

In the present investigatons, bio-efficacy of different doses of ready mix molecule Pyriproxyfen 8% + Clothianidin 3.5 SE as foliar spray was tested against cotton sucking pests, which revealed that the above said molecule @ 1500 ml and 1250 ml ha-1 was found most effective. The greater dose of the chemical also did not result in any symptoms of phytotoxicity on the crop.
