Because the tigers are extremely harmful to the growth of corn, we need to be able to detect and prevent their spread in time and reduce losses.
The general way is as follows:
Poison bait method: use 2.5% cyfluthrin or high chlorine • chlorpyrifos or high chlorine • chlorpyrifos 150g plus 1kg of water, spray and spray on 10kg wheat bran (or corn husk, or gluten), mix while spraying, mix evenly Made of poison bait. In the evening, sprinkle around the corn seedlings to trap the small tiger larvae, and use 5 kg of poison bait.
Spray method: The serious occurrence of the plot is sprayed after 5 pm. Use 2.5% cyfluthrin EC 2000-4000 times solution, or 40% chlorpyrifos EC 800-1000 times solution, or 25% thiamethoxam water dispersant 2000 times solution spray control. Soil treatment: use 50% phoxim or 40% chlorpyrifos plus water spray sand mixed fine soil 40 kg, piled up for 4 hours. In the evening, the seedlings were applied to the roots of the seedlings, and 20 kg of poisonous soil was used per mu.
Manual capture: a census of seedlings, captured from the victim seedlings.
The above several methods are commonly used, and the effect is remarkable.
