Producers are being urged to follow a three-point rodent control plan this autumn, to avoid significant infestations later in the year.
Thorough farm checks, consistent baiting schedules, and the use of effective baits will all be key to an effective control plan, according to BASF.
“Thorough preparation is particularly important at this time of year,” says the company’s Sharon Hughes.
This is because resistance to some anticoagulant baits, and the requirement for producers to be trained in order to purchase greater than 30ppm anticoagulant rodenticide baits, has changed how they can effectively target rodents.
"Baiting needs to be planned and consistent, using a highly palatable product to control rodent numbers on farms,” she says.
“It is believed that all baits have a high rate of efficacy and that rodents have little to no resistance to them.
“But this is not the case. Rats have already shown resistance to first-generation anticoagulants, as well as the second-generation anticoagulants difenacoum and bromadiolone."
The company has developed Storm Ultra Secure(r), a 25ppm flocoumafen-based bait to control rodent infestations on farms.
“However, the type and concentration of the active in rodent baits is only one factor in effectively controlling infestations in rural areas,” stresses Miss Hughes. “Preparation, consistent baiting schedules, and well-placed bait will all help to control farm rodent infestations.”
