Abstract

Aim: The aim of this study was to assess the performance of botanical extracts against cotton whitefly in the field conditions.

Materials and Methods: This experiment was done at Adaptive Research Farm Rahim Yar Khan, Punjab. Synthetic pesticides were excessively consumed to control crop pests but abundant use of chemicals may implicate the whole ecosystem badly in the end. Botanical spray was used against sucking pests to delay the application of first pesticide for maximum number days.

Results: All plant products showed varying toxicity against whitefly of Bt cotton 24, 36 and 48 hours after application. Tobacco + neem and kortomma each @ 1483g/ha proved to be more effective (75.4%) against cotton whitefly followed by tobacco+ kortomma each @1483g/ha i.e (66.9%) whitefly mortality. The pest scouting data of trial plot clearly show the decrease in pest population after application of neem extract i.e (55.8%).

Conclusion: It was concluded that all the botanicals proved to be effective for controlling cotton whitefly but the combined effect of these botanicals Tobacco + neem and kortomma.
