The roots of worms and snails in corn fields
The larvae of corn that harm the rhizomes are two-pointed moths, and can be controlled by PuZun 3000 times solution spray. There are three ways to control snails, one is agricultural control: (1) Cultivation with mulching. (2) Using clean gardens, eradicating weeds, timely cultivating, draining water and other measures to destroy snails and spawning sites. (3) Ploughing in the fall caused part of the overwintered adult shellfish, larvae and eggs to be exposed to the ground and freeze to death, sunburned, or eaten by natural enemies. The second is to manually capture: do traps in the field, so that the snails lurk under the traps and catch them before dawn. Set up lime belt: Lime belt on the edge of the ditch, land or crop, 1 to 5 kg of quick lime. Third, chemical control: (1) Polyaldehyde was used to mix 2.5% to 6% of effective baits such as beancake powder or corn flour, which was baited in field ridges in the evening. (2) Sprinkle 10% Mita granules or 10% poly acetaldehyde granules 2 to 2.5 kg per acre in the field. (3) When the snail does not sneak into the soil in the early morning, spray it with 800 times of copper sulfate, 100 times of ammonia, or 1% salt water.
