To Evaluate the Efficacy the new formulation of ready-for-use bait Samirat ® 2% against Nesokia indica and Microtus socialis in Kerman and West Azerbaijan provinces in Iran

Customarily Zinc phosphide poisoned bait has to be prepared on the field which is timeconsuming and hazardous to the users and the environment, hence ready-for-use zincphosphide baits (Samirat® 2%) was produced as wax pellets to overcome thesedifficulties. Samirat® efficacy was evaluated against rodents in West Azarbaijan andKerman provinces. Experiments were performed in RCBD with 5 treatments and fourreplicates. The results in West Azarbaijan show that 5 grams of Samira® with per-baiting for M. socialis with 84.69% showed the highest efficacy. However, in Kermanprovince the treatment of 10 grams and 5 grams Samirat® without pre-baiting for N.indica with 71.99% and for M. socialis with 71.41% showed maximum efficacyConsidering the acceptable efficacy and ready- for-use nature of Samirat® it is muchsafer, less hazardous and easier to use this new formulation than the commonly prepared zinc phosphide bait to control the rodent pests.
