Abstract/ Executive Summary:

An experiment was conducted during 2009-2010 at Regional Agricultural Research Station, Jamalpur to findout the effective fungicide against leaf spot and rust disease of groundnut. Among the tested seven fungicides of different groups, all the fungicides reduced the disease over control but the fungicides Sinazeb and Rajland was the best against the disease like standard fungicide contaf. The highest yield was also found from the contaf treated plot(1.5 t/ha) was statistically identical with Sinazeb and Rajland treated plot.

Keywords: Groundnut, Leaf spot, Rust

Location: RARS, Jamalpur

Start Date: 01-11-2009

End Date: 18-05-2010

Program Area: Pest Management

Commodity: Fungicide

Objectives:

To find out the effective fungicide against leaf spot and rust disease of groundnut.

Methodology:

An experiment was conducted at Regional Agricultural Research Station, Jamalpur during rabi season 2009-2010 to find out the some new fungicides for controlling the leaf spot and rust disease of groundnut. Five new fungicides namely Sinazeb, Rajland, Nuben, Amicomil, and Sincar including a standard fugicides contaf was used in the experiment. The treatments ie. six fugicides and one udsprayed control were arranged in the experiment following Randomized Comple to block Design (RCBD) with three replications where the unit plot size was 3 m x 1.8m.Seeds of the groundnut variety Dhaka-1 was sown in the field on 01 November 2009. Fungicide application was started just from the initiation of the disease an continued on 4 times at 10 days interval. After maturing crop was harvested on May 18, 2010. Data on disease incidence, Disease severity, Yield and yield contributing characters were recorded and analyzed statistically

Achievement/Findings:

Results of the experiment revealed that in cases of leaf spot disease the lowest disease severity was observed from the statndard fungicide Contaf (12.2%) that was statistically identical with the disease severity of the fungicide Sinazeb, (15.1%) and Rajland (16.2%). In case of rust disease the lowest disease severity (10.1%) was observed with the application of contaf that was statistically identical with the fungicide Sinazeb (13.3%) and Rajland (15.1%). Incase of yield the highest yield (1.58 t/ha) was found from the contaf treated plot that was statistically identical with Rajland (1.19 t/ha) and Sinazeb (1.11 t/ha) treated plot.
