    Evaluation of integrated rodent pest management technology in fodder crops
    (Punjab Agricultural University, Ludhiana, 2022) Gurpreet Kaur; Babbar, Bhupinder Kaur
    Bajra and berseem act as reservoir crops to the rats. By managing rats in bajra and berseem, we can control rat damage in the upcoming and surrounding crops also. Till now, no work has done on rodent pest management in berseem and bajra. Surveys were conducted in three villages, Noorpurbet, Khairabet and Bhaga khurdh, district Ludhiana to determine the critical stage of rodent management in both crops. Results revealed abrupt increase in their population at two different stages in both crops and after harvesting or irrigation in surrounding fields. It was hypothesized that management of rodents at the determined critical stages in small patches of both crops could also reduce rodent damage in surrounding crop fields at a much-reduced rate. Comparison of different rodent management methods used in bajra and berseem on the basis of % reduction in rodent activity using Kruskall Wallis H test, duration of efficacy, cost of application, effect of management in surrounding fields revealed that integration of repellent based formulation (RBF-developed in our laboratory) with trapping is the most effective and ecologically safe method of rodent management. Integration of RBF (about 100 pouches/acre) with trapping (10 traps/acre) in surrounding fields reduced rodent infestation (65.8 to 97.6%) in both RBF treated bajra fields and in surrounding maize fields for 55 days at a cost of Rs 1161/-. Trapping efficacy of rats was found to increase near RBF treated surrounding fields. Testing of NSA bait (with both toxic and antifertility properties and developed in our laboratory) in bajra crop fields as a reservoir crop also revealed its both toxic and antifertility effects in real field conditions and can be used to reduce rodent infestation for long duration
