Abstract

The date palm tree has the special important in the lives of the inhabitants of tropical regions. Among the pests of date palms, rodents (rats) cause damage to the tree and its crop in various ways like many other crops. In Kerman province the Bandicoot rat is the most common species. Rats weaken and eventually dry out date especially by digging tunnels inside the root mass and trunk of the palm tree. In this study, five common rodenticides in the country were compared in a randomized complete blocks design with six treatments and three replications in a palm orchard in the Shahdad region of Kerman province. Rodenticides were included Semirat, Brodifacoum with two formulations of pasta and wheat poisoned bait, Zinc phosphide, and Aluminum phosphide tablets. Results showed that Aluminum phosphide with 88.7% had the highest pest control rate, followed by Brodifacoum (wheat bait) with 70.3, Zinc phosphide with 69, and Brodifacoum (pasta) with 59.3 mortality rate, showed almost the same percentage of effectiveness. Finally, the rodenticide Semirat with 40% had the lowest pest control rate.
