Evaluation of Bromadiolone Against House Mouse (Mus Domesticus) Populations in Irrigated Soybean Crops. Ii. Economics.

摘要: The economics of controlling house mice [M. musculus] using 0.005% bromadiolone-treated wheat placed in bait stations within soyabean crops was evaluated New South Wales during 1989 when mouse densities were approx. 200-300/ha. Damage by to assessed up 200 m into 2 (1 with and 1 without) on each farms just before baiting, 22 42 d after baiting. Mouse damage crop always <10%, greatest patches high density. similar at the perimeters 100 crops, but from perimeters, less prevalent. By differences losses relative pre-baiting levels minimal. Estimates caused 3 principal growing regions obtained all farmers who grew soyabeans 1988-89. combined growers these about $A2 million.
