Abstract/ Executive Summary:

An experiment was conducted at PRSS, Joydebpur Gazipur and RARS, Rahmatpur, Barishal during 2011-2012. Results reveled that for PRSS, Joydevpur Gazipur, the lowest CLS disease severity was found in Secure 600 WG treated plot (2.00%) where BARI Mung-6 was used and the highest disease severity was found in untreated, plot treated plot where BARI Mung-4 was used as well as yield (1471 kg/ha) and yield attributes (pod length, plant/pod and 100 seed wt) also higher among the all treatments. Result reveled that for RARS, Rahmatpur, Barishal, Bavistin (0.15%) gave the lowest PDI (22) and highest yield (1450 Kg/ha) in controlling Cercospora leaf spot of Mungbean followed by Secure 600 WG (1204 Kg/ha).

Keywords: Management package,Cercospora leaf spot, Mungbean

Location: PRSS,BARI, Joydebpur Gazipur and RARS, Rahmatpur

Start Date: 00-00-2011

End Date: 00-00-2012

Program Area: Pest Management

Commodity: Mungbean

Objectives:

To find out the effective fungicide for controlling cercospora leaf spot of mungbean

Methodology:

The experiment was conducted at RARS, Barisal and Pulses Research Sub-Station, Joydevpur Gazipur during 2011-2012. The experiment was laid out in a well-prepared land. The design was RCB having 3 replications. The variety used was BARI Mung-1. There were 6 treatments namely Neem leaves extract (1:10), Score (0.2%), Secure 600 WG (Fenamidone + Mancozeb) (0.2%), Bavistin (0.15%) and two check i.e. BARI Mung-1, BARI Mung-6. The crop was sown on 10 February 15 March of 2012 ar Gazipur and Barishal, respectively. Five sprays were given at an interval of 10 days while the first one was applied just at the appearance first disease symptom. Disease data were recorded before every spray using 0-8 rating scale which developed by Mehta and Haque (1994) as follows; Where 0 = free from spot, 1 = 0.1-3.0% leaf area infection, 2 = 3.1-6% leaf area infection, 3 = 6.1-12% leaf area infection, 4 = 12.1-25 % leaf area infection, 5 = 25.1-50.% leaf area infection, 6 = 50.1-75 % leaf area infection, 7 = 75.1-87 % leaf area infection and 8 = above 87 % leaf area infection. Percent disease index (PDI) was computed from the final data. The data was analyzed statistically for DMRT. (Zaman et al., 1982) Percent Disease Index (PDI) was computed.
