How to prevent and control pests and diseases in walnut cultivation
How to prevent and control pests and diseases when growing walnuts? Please give guidance. Here are two walnut pest and disease control methods for reference: Control method for the walnut shoot borer: The walnut shoot borer, commonly known as "walnut black," has adults that appear from June to July, and larvae that cause the most serious damage in July. This pest has weak resistance to pesticides, so you can choose pollution-free pesticides such as 10% cyhalothrin EC at 1500-2000 times dilution, or 15% imidacloprid at 3000 times dilution, and begin control at the end of June. Spraying once more after 7-10 days gives better results.

Control methods for anthracnose and black spot disease: Both of these diseases can cause fruit rot and are relatively serious diseases in walnut production. Moreover, both diseases peak during the rainy season in July-August. Before the rainy season arrives, choose 50% carbendazim at 800-1000 times dilution or 50% thiophanate-methyl at 500-800 times dilution for control.
