In vitro efficacy of fenazaquin 18.3% w/w (200 SC) against Polyphagotarsonemus latus Banks (Acari: Tarsonemidae) in chilli ​

Yellow mite, Polyphagotarsonemus latus is one of the important pests in chilli ecosystem and causes considerable yield loss. Synthetic acaricides play a major role in the management of yellow mites. A novel pesticide, fenazaquin 18.3% w/w (200 SC) was evaluated under laboratory conditions against two standard checks viz., fenazaquin 10 EC and spiromesifen 22.9% SC that are frequently used in vegetable ecosystems with water as control, in an effort to find more effective alternatives to the existing chemicals. Various doses of fenazaquin 18.3% w/w (200 SC) tested exhibited significant mortality. After 6 days of treatment, 100% mortality was recorded in fenazaquin 18.3% w/w (200 SC) @ 1.25 and 1.60 ml/l followed by 95% in fenazaquin 10 EC @ 2.5 ml/l, 92.5 % in fenazaquin 18.3% w/w (200 SC) @ 1 ml/l and 87.5% in spiromesifen 22.9% SC @ 0.80 ml/l.
