Embodiment Construction

[0010] After actual investigation, it is proved that the related factors of its incidence include:

[0011] Site conditions: light on sunny slopes and heavy on shaded slopes.

[0012] Cultivation environment: poor ventilation and light transmission, interplanting high-stalk crops, serious disease.

[0013] Varieties: Dahongpao is heavy, bean pepper, and dog pepper are light.

[0014] Cultivation conditions: scattered pepper trees are light, and sliced ​​pepper trees are heavy.

[0015] In view of the above characteristics, the measures taken include:

[0016] 1. Manual control methods

[0017] ①Clean the garden to eliminate overwintering pathogens.

[0018] ② Strengthen fertilizer and water management and enhance tree vigor.

[0019] ③ Cultivate disease-resistant varieties, mixed with Dahongpao.

[0020] 2. Chemical control measures

[0021] ① From early June to late July, spray with tebuconazole (or triadimefon, propiconazole) 600-800 times liquid.

[0022] ②Spray 1:2:600 Bordeaux mixture (1 ...

Abstract

The invention aims to provide a prickly ash rust preventing method. Particularly, the prickly ash rust preventing method comprises the following measures: firstly, manual pastoral management measures: 1, cleaning the pastoral field and killing overwintering diseases; 2, reinforcing fertilizer and water management and enhancing tree vigor; and 3, growing disease-resistant species and planting other species and Dahongpao tea species in a companion manner; and secondly, chemical control method: 1,during early June to late July, spraying with 600 to 800-fold liquid of tebuconazole, triazolone or propiconazole; and 2, after fruit harvesting as well as before sprouting in spring, spraying with Bordeaux mixture composed of cupric sulfate, calcium oxide and water at the weight ratio of 1:2:600. Field tests prove that the prickly ash rust preventing method has a very good preventing and controlling effect on prickly ash rust.

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...
