Abstract/ Executive Summary:

The experiment was conducted in the field of Central station, Dhaka in Randomized plot(3mx3m) with three replications. To evaluated the efficacy of green neem leaf extract and turmeric powder extact against jute yellow mite. Pesticidal activity of neem (Azadiracta indica) was found promising which exhibit the mortality as well as feeding activities of jute yellow mite and could help evolve eco-friendly and bio-alternatives, as a part of Integrated Pest Management(IPM). After sufficient natural infestation builds up in the field, turmeric powder (1:40) and green neem leaf (1:20) extract were sprayed on the plants. The control plants were remaining untreated. Each treatment was replicated 3 times. Percent materials. Fibre weight was taken for calculating percent yield increased over control. Both the materials showed equal performance, about 52% mortality after 72 hrs of exposure. The highest percent reduction of infestation was recorded from turmeric powder (28.34%) treated plots followed by green neem.

Keywords: Evaluate, Plant materials, Yellow mite, Jute

Location: Central station, Dhaka

Start Date: 30-03-2003

End Date: 30-10-2003

Program Area: Pest Management

Commodity: Jute

Objectives:

i. To evaluate the effectiveness ofgreen neem leaf extract and turmeric powder extract.

ii. Find out the most appropriate dose of selected plant materials

Methodology:

Preparation of green neem leaf extract Fresh green leaves were collected from the campus of BJRI, Dhaka. The collected leaves were washed under running tap water. Hundred grams of Air dried leaves were taken into an electric blender with 1000 ml of water. After blending the leaves well, the mixture was filtered through a fine cloth then the extract was considered as 1:10 neem leaf extract. Similarly 1: 20 and 1:30 neem leaf extracts were prepared by adding 2000 ml and 3000 ml of water with 100g of leaves, respectively.

Preparation of Turmeric powder extracts:One hundred gram of turmeric powder were soaked separately in 1000 ml, 2000 ml and 3000 ml of water and kept for 2 hours, then filtered through linen cloth to prepare 1:10, 1:20 and 1:30 (materials : water) turmeric powder extracts. Prepared extracts were sprayed in yellow mite infested plants and calculate % mortality and % reduction of infestation.
