Abstract/ Executive Summary:

An experiment was conducted during 2009-2010 cropping season to evaluate some new fungicides in controlling Alternaria blight disease of mustard in the field of RARS, Jamalpur. There were five fungicides namely; Movral, Telus, Alphadione, Memoral and Arodione with check Rovral were sprayed @ 0.2%, 4 times at 10 days interval. The experiment was laid out in RCB Design with 3 replications. Significantly the highest disease reduction (90.7%) was obtained from Movral treated plot that was identical with Memoral, Arodione and Rovral treated plot. Moreover, maximum yield (1.75t/ha) was obtained from Movral treated plot followed by Memoral, Arodione and Rovral treated plot.

Program Area: Pest Management

Commodity: Mustard

Objectives:

To evaluate some new fungicides against Alternaria blight disease of mustard

Methodology:

The field study to find out the efficacy of fungicides against Alternaria blight disease of mustard (Var. BARI Sharisha 15) was conducted at RARS, Jamalpur during 2009-2010. Five different fungicides namely: Movral, Telus, Alphadione, Memoral and Arodione were included in the experiment. The experiment was designed in RCBD with 3 replications. Where plot size was 2.4m x 2m with 30 cm row spacing and each fungicides were sprayed @ 0.2 % according to the design at 10 day intervals beginning from the first appearance of the disease and continued to 4 times. Disease incidence, plant height (cm), no. of pod/plant, no. of seed/pod, yield /plot and seed yield (t/ha) were recorded.

Achievement/Findings:

The highest disease reduction (90.7%) was recorded on Movral treated plot whereas the maximum disease incidence was found from control plot. Disease reduction of Movral treated plot was statistically identical with Arodione, Memoral and Rovral treated plot. Maximum yield (1.75 t/ha) was obtained from the Rovral treated plot that was statistically identical with Arodione, Memoral and Rovral treated plot. The lowest yield (0.79 t/ha) was obtained from the control plot.
