• In order to overcome limitations and hazardous nature of acute rodenticides, lengthy baiting programme and possibility of resistance, new series of rodenticides have been developed and known as single dose anti-coagulants or second generation anti-coagulants.
These rodenticides (Bromodiolone) combines better qualities of acute and chronic rodenticides.
• For effective and successful rodent control, the following programme should be adopted on large areas at a time on community approach.
• Chronic or multi-dose rodenticides (at present only anti-coagulants) are much safer than acute rodenticides because they are less toxic to the non-target species. But they have to be fed for 5 - 7 days to obtain desired results, which increases the cost of operation
Day-1: Identify live burrows and place 15 g bromodiolone concentrate bait inside the burrow.
Day-2: Repeat Bromodiolone baiting in active or live burrows.
Day-3: Eliminate residual population through trapping or fumigation with burrow fumigator Principles
• Grow same maturity group cultivars on large areas to restrict the availability of the vulnerable stage (Reproductive) of the crop.
• Reduce the number and size of the bunds, keep them clean to locate burrows and avoid harborage.
• Rodent control operations should be taken up on large area at a time.
• It checks cross infestation or migration of rodents from untreated fields to treated fields.
• All the control operations should be completed before the crop attains primordial initiation stage since at this stage the rodents are invariably attracted to the rice crop.
• Rodenticides should be made available before beginning of the season.
