First, the occurrence and degree of harm
The second generation of corn borers has been observed with moderate infestation in certain areas. The most significant damage is occurring in late spring and summer corn crops. In our city, summer corn covers a large area, and if proper prevention and control measures are not taken, the infestation rate could exceed 35%. This level of infestation can severely impact yield and crop quality, making timely action essential.Second, the occurrence period and prevention window
The adult stage of the second-generation corn borer occurred between June 19 and July 3. The egg hatching period was from June 25 to July 10. Based on this, the optimal periods for prevention and treatment were scheduled as follows: the first window from June 27 to July 2, and the second window from July 8 to July 13. These timings are crucial to ensure effective control before the larvae cause extensive damage.Third, the agents and methods for prevention and control
1. During the heart leaf stage of summer corn, apply a mixture of corn snacks or earthworms with soil through foliar spraying. This method helps to target the pests directly and reduce their population effectively. 2. Use Kono special killing agent at a dosage of 50 grams mixed with two bags of water (equivalent to 100 pounds). Apply it evenly by spraying the entire plant, focusing on the heart leaves and tassels. This treatment also helps in controlling other pests like aphids. 3. For late-sown spring corn, apply a well-proportioned mixture of the special killing agent and spray it uniformly on the female ears, the upper and middle parts of the leaf sheaths, and the corn sheath. This approach is particularly effective against corn sheath blight and other related diseases. By following these strategies, farmers can significantly reduce the impact of the corn borer and protect their crops from serious damage. Regular monitoring and timely intervention are key to successful pest management. (Hubei Dangyang Agricultural 110 Service Center)Stainless Steel Wire Mesh
