Field trials of brodifacoum, chlorophacinone and coumatetralyl against desert rodents in India

Abstract

Held trials were conducted in 18 1-ha plots arranged as a 6×3 randomised block to evaluate brodifacoum (0.002%), chlorophacinone (0.0075%) and coumatetralyl (0.0375%) for the control of desert rodents, predominantly Meriones hurrianae Jerdon. Success was measured by counts of inhabited burrows before and four days after the treatment period of ten days. Average kills were 90.5, 83.2 and 81.1 % respectively. It is concluded that all three poisons are effective, but brodifacoum performed significantly better than either chlorophacinone or coumatetralyl.

Field Efficacy of Anticoagulant Rodenticides Against Rat Infestation in Oil Palm Plantation

“…The laboratory study by Marsh et al (1977) reported that 0.005% of chlorophacinone was able to achieve complete control against deer mice, Peromyscus maniculatus in four days of free choice feeding test. A comparative study by Mathur and Prakash (1984) showed high efficacy of up to 90.5% The poor result of warfarin bait treatment aligned with past literature which reported that the poor efficacy of the compound that contributed to poor control in the field was largely due to resistance (e.g. Wood and Chung, 1990;Wood and Liau, 1977).…”

Rodent control in practice: tropical field crops.

“…Their hoarding behaviour would probably make multiple-dose anticoagulant baits costly to use except in low-level maintenance control programmes. Nevertheless, the use of chlorophacinone and coumatetralyl, as well as the single-dose anticoagulant brodifacoum, each formulated in a pearl millet base, reduced active burrows by 83, 81, and 91%, respectively, after 10 days (Mathur and Prakash, 1984).…”
