Description

Technical field

[0001] The invention belongs to the technical field of agricultural crops, and particularly relates to a method for preventing and controlling Zanthoxylum bungeanum disease. Background technique

[0002] Pepper rust causes a large number of pepper leaves to fall off after picking peppers, which affects the accumulation of nutrients in the year. When the weather picks up, the second buds will germinate and consume nutrients, which will affect the yield and quality of the next year.

[0003] Rust mainly damages the leaves. At the initial stage of the disease, water-soaked chlorotic spots with a diameter of 2 to 3 mm appear on the front of the leaves, and round yellow-brown urea piles appear on the back of the corresponding leaves. Many piles of urea are arranged in a ring. In the later stage of the disease, the chlorotic spots develop into 3-6 mm dark brown necrotic spots. The leaf back produces brown, orange-red wax paper teliospore piles, the protrusions are not br...
