Current prevention and control of walnut pests and diseases

In recent years, due to the harm of walnut limb moth, anthrax, black spot, etc., the problem of black walnuts has been aggravated, which has seriously affected the yield and quality of walnuts. Currently, at the peak of these three kinds of pests and diseases, fruit farmers should seize the time and take effective measures to prevent and control them.

?? Walnut moth extermination methods: walnut exhumation moth commonly known as walnut black, adults in June to July, larvae in July the most serious harm. The insects have relatively weak antibiotic resistance, and they can choose the pollution-free pesticide 10% empermethrin EC 1500-2000 times, 15% imidacloprid 3000 times, and begin to control at the end of June. After 7 to 10 days, it can be sprayed once more.

?? Anthracnose and black spot prevention and treatment methods: These two diseases can cause fruit rot, is a relatively serious disease in walnut production. Moreover, both of these diseases occurred at the peak of the July-August rainy season. Before the rainy season comes, choose 50% carbendazim 800-1000 times, 50% thiophanate-methyl 500-800 times for control.
