Abstract: Many plant extracts could be considered as natural effective tool against yellow mite instead of synthetic chemicals. The research was aimed at studying the effects of plant extracts on Polyphagotarsonemus latus Banks infestation and jute yield production. This experiment was conducted in Manikganj, Bangladesh following randomized complete block design with three replications. Treatments were Neem oil 3% (T1), Neem leaf extract @ 1:30 (T2), Mahagoni seed extract @ 1: 10 (T3) Turmeric powder extract @ 1: 40 (T4), Garlic paste extract @ 1:30 (T5) and control (T6). Percent reduction of mite population was found in neem oil (87.94%), neem leaf extract (85.76%) and garlic paste extract (86.48%) at 72 hrs after spray. After 7 days of spraying, Neem oil treated plot received the best reduction (89.05 %) followed by neem leaf extract (87.03%), Mahogany (79.60%), turmeric (78.02%), and garlic (80.06%), respectively. Neem oil treated plot showed highest fibre yield (2.95tha-1). Control plot showed highest mite infestation with lowest yield contributing attributes. Neem oil/leaf extract and mahogany seed extracts were found effective to control yellow mite infestation resulting higher fibre yield production.
