The repellency of cow dung for controlling rodents was evaluated in the wheat field of Dinajpur during December 2010 to June 2012. Four different concentrations of cow dung solution i.e. 0%, 5%, 10% and 30% were used for controlling rats. At ripening stage of wheat 20% cow dung solution was found effective (50% success) followed by 10% poultry litter solution (40% success) and 5% cow dung solution (10% success).

To find out the effectiveness and locally available repellent for rodent control
The experiment was conducted in the wheat field of Dinajpur, during December, 2010 to June 2012. where clear signs of rodent infestation were detected. There were four treatments of this experiment viz.. 0%, 5%, 10% and 20% cow dung solution were used for controlling rats with untreated control where no cow dung was used. Only active burrows were used for this experiment. Burrows having clear symptom of rat inside with fresh soil in the opening were considered as active burrows. Ten active burrows were used for each treatment. Before applying treatment all the active burrows were identified properly. Foot tracts activities were taken for two nights for both pre and post treatments operations.
Preparation of Cow dung and poultry litter solution
Cow dung was prepared by mixing a certain amount of cow dung in water. For preparing 20% , 10%, 5% cow dung solution; 200g, 100g and 50g cow dung was mixed with 1 (one) L of water respectively. This mixture was blended for about 5 minutes and put in a water pot. These solutions were used for treating active rat burrow.
Cow dung solutions were applied inside the burrow opening of active burrow system. Two liters of cow dung solution were applied by water pot in one active burrow system in each treatment. The prepared solution was applied in the evening and continued for consecutive two days. In case of untreated control treatment, active burrow systems were treated with pure drinking water only. After applying the treatments the entire burrow opening were closed by soil. After application of the treatments, rodent activities were observed up to seven days. Efficacy of the treatment was judged on the basis of rodent activities based on active burrow opening and foot print on the tracking tiles.
VPD Annual Report, BARI, Gazipur
Thirty thousand
The effectiveness of cow dung solution for controlling rodents in. It is revealed that the rodent controlling success differed significantly (1% level) among the treatments. In active burrow count method, the rodent controlling efficacy for 20%, 10% and 5% cow dung solution was 50.00%, 40.00% and 10.00% respectively in wheat fields. Twenty per cent cow dung solution showed the highest success (50.00%) . Only 10.00% success was recorded in case of untreated control treatment where no cow dung was used. The result showed the more or less similar efficacy in case of tracking tile count methods .The findings of the experiment could be used as a eco-friendly tool for integrated rodent management, which will be used as environmentally sound and cost effective technology for controlling burrowing rats compared with the present method of rat control.
