Grasp the tigers in the corn field

In the prevention and control of ground tigers, measures must be taken to combine moths, weeding, pharmacy, and artificial control to effectively control the damage.

It is the best policy to control adult tigers by trapping adult insects, which can greatly reduce the number of first generation larvae. The method is to use black light and sweet and sour liquid to trap.

Eliminating weeds and weeds is the spawning place of the tigers. It promptly removes weeds from the ground, the ground, and the Tianji road, and takes them to the field for timely treatment or manure, which can eliminate some eggs or larvae.

Spray control in the evening with 2.5% deltamethrin EC 2000 times solution or 4.5 days Longbao beta-cypermethrin EC 3500 ~ 4000 times solution or 50% phoxim EC 1000 times solution spray.

Applicator toxic soil, sand prevention drug with 50% phoxim 0.5 kg amount of water, mixed with 100 kg fine soil injection, or parts of 20% with a mevinphos permethrin EC 2000 parts sand mix uniform field applicator.

Bait trap for fourth instar larvae with more than bait trap better. The 0.5 kg of 90% water-Open trichlorfon, add approximately 5 liters of water, sprayed on the saute soapstock (also used instead of cottonseed husks) with stir Serve. 4 to 5 kilograms of poison bait per acre , applied in the evening.

In instar agent IRRIGATING larger dichlorvos EC with 80% or 50% phoxim, 0.2 kg of drug per acre IRRIGATING watered 400 kg, applied to the plant stem or prevention.

Artificially catching the damaged land, when there is a broken seedling in the field, the topsoil or wheat straw near the broken seedlings can be opened in the morning to kill the young larvae.
