Corn borer is one of the important pests that harm the growth of corn, and poses a serious threat to the yield and quality of corn. The following are some specific control methods for corn borerworm.
*Analyse. The corn borer mainly eats the larvae inside the corn stalks, and in severe cases, it can cause the corn plant to break, reduce yield and even die. This poses a serious hazard to the growth and yield of corn.
Prevention and control methods. Biocontrol.
Release of natural enemies: Introduce natural enemies such as parasitic wasps and predatory natural enemies to effectively control corn borers.
Cultivation of insect-resistant varieties: choose corn varieties with strong resistance to plant to reduce the harm of corn borerworm.
Agronomic measures. Reasonable dense planting: Appropriate adjustment of corn density, through reasonable dense planting can reduce the spread and damage degree of corn borerworm.
Dredging and drainage: keep the corn field ventilated and light-transmitting, remove stagnant water in time, and reduce the chance of corn borer breeding.
Chemical control. Spraying insecticides: In the early stage of corn damage or when adults appear in large numbers, spraying with effective insecticides is used to control the number of corn borers.
Rotation of pesticides: Regularly change insecticides using different mechanisms to avoid insect infestation resistance to specific pesticides.
Integrated control. Monitoring and control: regularly inspect the field, keep abreast of the occurrence of corn borerworm, and scientifically formulate prevention and control plans.
Light trapping: The use of light sources to trap adult worms and reduce their reproductive numbers, thereby reducing the breeding of larvae.

For the control of corn borerworm, we can adopt a variety of means such as biological control, agronomic measures, chemical control and integrated control. Through scientific control measures, the damage of corn borer to corn can be effectively reduced, and the yield and quality of corn can be improved. Hopefully, the above suggestions will help you better control the corn heartworm and ensure the healthy growth and harvest of corn.
