According to the extent of damage to the crops and irrigation canals the Nesokia indica is one of the most important rodent pests in Iran. Cymag is a registered product in the country to control Citellus fulvus and large amount of it is available at present. With the aim of studying the effect of it on the N. indica experiments were conducted under field conditions in Tehran and Kerman Provinces. The experiments were performed in a completely randomized block design in four replicates with two experimental and one control block with the extend of about 500 square meters each. The treatment blocks included 2-8 g Cymag/complex burrow (based on the average volume of the burrows), and 1-2 Phostoxin tablets/complex burrow, and the third block was the control without any rodenticide. Percentage success was estimated using Henderson and Tilton (1955) formula. The results show the success of about 98 and 96.4 percent using Cymag and 88.5 and 89.5 percent using Phostoxin tablets in Tehran and Kerman provinces respectively. Higher efficacy observed in Tehran province could be due to higher moisture present in the soil of this province. Since Cymag is highly toxic, it must be used by trained personnel and farmers using suitable safety measures.
