Current study was conducted to check the efficacy of different zinc phosphide formulations (Hit rat + crushed wheat, hit rat + sweat, ractophos + crushed wheat and ractophos + sweat) in the form of baits, Agtoxin and ultrasonic repellant devices against rats in a sugarcane field. Experiments were conducted in field area of sugarcane crop in Chak No. 33 J.B. Faisalabad, Pakistan for two consecutive years 2017 and 2018. The crop was sown in February, while treatments were applied from June to October. Data regarding the number of burrows was taken in November, while tile activity was recorded on a fortnight basis. The yield was recorded at the crop harvest. The efficacy was calculated in the form of reduction in number of burrows, decrease in infestation, decrease in sugarcane yield and recording the activity of rats on tiles placed in sugarcane fields. Results revealed that highest reduction in a number of burrows was found in agtoxin (96.25%) and then in hit rat + crushed wheat bait application (87.54%), while a lowest reduction in a number of burrows was observed in the ultrasonic repellant device (58.73%). The highest decrease in infestation was observed in hit rat + crushed wheat treatment (84.21%) while the lowest was in the ultrasonic devices (40.23%). The highest yield of sugarcane was recorded in hit rat + crushed wheat (943.14 M/acre) while the lowest was in the ultrasonic repellant device (853.05 mond/acre). Minimum rat activity was observed in Hit rat and crushed wheat treatment while maximum in repellant device treatment in both the years in tile experiment. The present study results indicated that Hit rat + crushed wheat treatment proved best among all the treatments. The yield of sugarcane can be enhanced and infestation of sugarcane by rats can be reduced by the use of this application treatments, which will enhance the profit of sugarcane farmers.
