Population Trend of Onion Thrips and Its Botanical Approach to Sustainable Management

This research is about onion (Allium cepa L.) which is an important commonly grown vegetable in kitchen gardens and for commercial purposes throughout the globe its crucial. Plant phytochemicals are playing an important role in pest management, and when combined with synthetic pesticides, they increase toxicity due to a synergistic effect. The current study compares effectiveness of Lantana camera leaf extract and its combination with diamethoate 30EC against onion thrips were compared. It has resulted that thrips colonization began on the 9th SMW and peaked on the 15th SMW. Thrips colonization was maximum at high temperature and low rainfall but relative humidity depleting the thrip population. All treatments were found to be significantly more effective than the control against thrips. Lantana camera leaves extracts at 50 g L-1 as the sole and in combination with dimethoate 30EC between 150 and 250 mL ha(-1) were found to be a promising combination.
