Abstract/ Executive Summary:

To evaluate the efficacy of nine new acaricides against jute yellow mite an experiment was carried out at JAES, Manikganj and Jute Research Sub-station Tarabo, Narayanganj during the jute-growing season (April-August) 2018. Revenge 1.8EC, Actos 1.8EC, World 1.8EC, Haba 1.8%, Lock 12SC, Himectin 1.8EC, Biomectin 1.8EC, Best Albatin 1.8EC, Power Prid 95SP respectively were found effective for controlling jute yellow mite giving more than 87% reduction of infestation and at JAES, Manikganj and more than 85% reduction of infestation at Tarabo, Narayanganj at 7^th day after spray. All acaricides can be recommended for farmer’s use.

Program Area: Pest Management

Commodity: Pesticide, Jute

Objectives:

To evaluate the efficacy of new acaricides against jute yellow mite for recommendation of farmer's use

Methodology:

During the jute growing season, April–August 2018 an experiment was conducted in two different locations JAES, Manikganj, Tarabo, Narayanganj following Randomized Complete Block Design (RCBD) with three replications. A standard tossa variety O-9897 was sown at the mid of April and allowed to build up a natural infestation in the fields. After sufficient infestation in all the plots, new acaricide Revenge 1.8EC, Actos 1.8EC, World 1.8EC, Haba 1.8%, Lock 12SC, Himectin 1.8EC, Biomectin 1.8EC, Best Albatin 1.8EC, Power Grid 95SP, Haysulf 80DF (Standard) @ 600ml/ha, 600ml/ha, 600ml/ha, 600ml/ha, 500ml/ha, 600ml/ha, 600ml/ha, 600ml/ha, 250gm/ha and 1 kg/ha were sprayed in the plot. The control plots were treated with water. Percent reduction of the infested plant was recorded at 7^th days after spray. The percent reduction of infestation in each treatment was calculated by using the following formula:

% Reduction = [( No. of infested plant before spray – No. of infested plants after spray)/ No. of infested plants before spray]× 100

Achievement/Findings:

All tested acaricides can be recommended for the farmers’ use. This new chemical acaricide will help to overcome the resistance problem of yellow mite against chemical acaricides. Besides this, farmers will have a chance to select alternate chemical acaricides according to availability and cost.
