From mid-August to early September, it is the earliest stage of the threat of corn earworms. The pests that threaten corn include cotton bollworm, corn borer, armyworm, peach aphid, sorghum strips, and autumn caterpillars. With the increase of planting cornices in recent years, the intercropping and intercropping area has provided multiple sources for corn earworms and the formation of concentrated damage during the ear period, which has a greater impact on the yield and quality of corn. In the year of the occurrence of corn earworms, generally one to two percent reduction in yield and affect grain quality. According to the author's investigation, the occurrence and damage of corn earworms have two major characteristics: First, due to the difference between the silking stage of corn and the planting plots, the extent of the damage is very different. In the same year, early and scattered plots of corn were planted on silk plots. The rate of damage to maize earworms was as high as 60% to 80%; The rate is generally 10% to 30%. Second, corn earworms are dominated by bollworms and corn borers, accounting for 80% to 90%, and the remaining pests only account for 10% to 20%. To master the characteristics of the occurrence of corn earworms, we can take effective control measures. The earliest period of prevention and control of corn earworms: The filaments of the ear begin to wilt and the corn pollination has just ended. Premature prevention and treatment during the prosperous period of the ear, will affect the pollination of the corn; if the prevention and treatment are too late, the pests have penetrated into the ear to cause harm, leading to difficulties in control and prevention and control. The period from mid-August to the end of August in China's Huang-Huai Region is the main period for the majority of summer maize flowering and pollination. To prevent and control corn ear-worms, we must seize the best period of prevention and control and implement comprehensive prevention and control. After removing the flour from the silk corn, timely cut off the filaments together with the 1 to 2 cm loquat leaves on the top of the ear with scissors, and take all the sheared things out of the field to centralize the treatment to prevent pest transfer hazards. Pesticide control Pesticides are used immediately when there are 25% to 30% of the pests or 40 pests of 100 plants. Use 80% of dichlorvos EC 800 times, apply cotton thread liquid to scab the filaments, or use 2.5% deltamethrin EC 200~300 drops into the top of the ear of corn, dropping 6~10 drops of each ear (ie 8 (10ml); or with 2.5% lambda-cyhalothrin EC 1500 times, or 4.5% beta-cypermethrin EC 1500x, directed at the head and filiform spray; or with 3% phoxim granule 400 per mu 500 grams, with 5-6 kilograms of fine sand, sprinkled between the leaves of the upper and lower leaves of the filaments and the ear.
