Abstract/ Executive Summary:

Experiments were conducted at Central station, Dhaka and JAES, Manikgonj in Randomized plots with 3 replications, to see the effectiveness of new acaricides. Acaricides Vitasul 80WP, Agrovet DF 80 @ 2.2 kg/ha. were found effective in controlling yellow mite giving 81.16 and 85.55% mortality, respectively at Central Station, Dhaka fter 72 hours of exposure. The percent deduction of plant infestation at 10 days after treatment were about 90% at Central station and more than 99% at JAES, Manikgonj. Vitasul 80WP, Agrovet DF 80 @ 2.2 kg/ha. may be recommended to grower for the control of yellow mite.

Keywords: Effect, new, acaricides, yellow mite, jute

Location: Central station, Dhaka and JAES, Manikgonj

Start Date: 30-03-2008

End Date: 30-11-2008

Program Area: Pest Management

Commodity: Jute

Objectives:

1. To see the effectiveness of some new acaricides against jute yellow mite

2. Recommendation of acaricides against jute yellow mite

Methodology:

Experiments were conducted at Central station, Dhaka and JAES, Manikgonj in Randomized plots with 3 replications. After sufficient natural infestation of yellow mite built up in the field, selected chemical acaricides; Agrovet DF 80 and Vitasul 80 WP were sprayed along with standard acaricides Prosulf DF 80 @ 0.12% a.i. ( 2.2kg/ha) . The control plots were remain untreated. Population of mite was recorded by examining leaf sample ( 1 sq.cm ) under bionocular microscope before spray and corrected percentage of mortality was observed at 24, 48 and 72 hours after spray only at Central station, Dhaka. Percent reduction of plant infestation was recorded at 3, 7 and 10 days after treatment in both the test places.
