| Use | anticoagulant rodenticide, strong toxicity, effective against resistant rat species, good palatability, with acute and chronic rodenticide effect. Used for the control of wild and domestic rodents. For the prevention and control of harmful rats in farmland, a bait point shall be set up every 50m2 of the route for harmful rats to enter and exit, and 5-10g of drug shall be administered at each point. If necessary, the toxic bait to be taken off shall be replenished, and it shall be effective in 4-8 days. A bait point was set every 5m for the prevention and treatment of rats. 20~30g per point, if necessary, the poison bait should be added for about 1 week. is a highly toxic rodenticide, used in urban, rural, residential, hotel, restaurant, warehouse, car, anti-rodent The second generation anticoagulant rodenticide for ship and field environment. The product is efficient, broad-spectrum, can effectively control a variety of rodents, a bait can make the rat poisoning death. |
