Abstract/ Executive Summary:

Fifty gm of jute seed (CVL-1 & O-4) and Castor seeds were crushed and soaked with 1 liter of water to get 1:20 ratio of concentration. All the tested plant materials except Merigold gave result in controlling yellow mite over control (Above 50% mortality). Green neem leaves showed best result followed by O-4 jute over control (Above 50% mortality). Green neem leaves showed best result followed by O-4 jute seed dust, Mehgonj, Castor, CVL-1 jute seed dust and Allamonda giving 60.59, 57.71, 57.67, 56.22 and 50.52% mortality, respectively.

Location: Central station

Start Date: 30-03-2006

End Date: 30-10-2006

Program Area: Pest Management

Commodity: Jute

Objectives:

1.To minimize the use of pesticides in pest control program.

2.To investigate the effectiveness of indigenous plant materials for the control of jute pests.

Methodology:

Jute plants were grown in pot at greenhouse premises.After sufficient natural infestation build up in the potted plants,different concentrations of selected plant materials were sprayed on the infested plants.The control plants were kept untreated and each treatment was replicated 4 times. Number of infested plants were recorded before spray and 3, 5 and 7 days after spray. leaf samples were collected and examined under bionocular microscope at 24, 48 and 72 hrs after spray and calculated percent mortality according to Abbot,sformula.
