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

Pricklyash Ruct is prevented and treated method

Technical field

The invention belongs to the agricultural crops technical field, particularly a kind of Chinese prickly ash pest control method.

Background technology

Pricklyash Ruct causes the green pepper leaf to come off in a large number after adopting green pepper, affects then nutrient accumulation, when weather gets warm again after a cold spell, sprout the secondary bud and consume nutrient, thereby impact comes annual production and quality.

Rust main harm blade, their early stage, 2-3 millimeters water soaking mode chlorisis of diameter spot appears in face of blade, and circular yellowish-brown uredium appears in corresponding leaf back, and many urediums are arranged in ring-type.Morbidity later stage chlorisis spot develops into 3-6 millimeters deep brown necrotic plaques.Blade back produces brown, orange red paraffin paper teleutosorus, and projection is not broken, rounded or Long Circle.

The occurrence regularity of green pepper rust is: rust general mid or late June begins to occur, and 7-September, early and middle ten days was the morbidity Sheng phase, and rust occurs with weather closely related, and the summer, the rainfall in autumn is many and when frequent, disease is large the generation easily.The many lower blade of rust begin morbidity, and to vertical spread, before and after the fruit maturation, a large amount of fallen leaves, October the sick leaf light that falls, the secondary bud occurs.Germ can be propagated by air-flow, infects frequent again.

Summary of the invention

The object of the invention provides a kind of Pricklyash Ruct and prevents and treats method.

Specifically, Pricklyash Ruct is prevented and treated method, and it comprises following measure:

First: artificial rural area control measures: 1. clear garden, eliminate the germ that survives the winter; 2. strengthen rich water quality management, strengthen tree vigo(u)r; 3. cultivate disease-resistant variety, with other kinds and the companion planting of clovershrub kind;

Second: the chemical control way: 1. at the beginning of 6 months-late July, with Tebuconazole or triazolone or propiconazole 600-800 times of liquid spraying; 2. behind the fruit harvesting, before germinate spring, each sprays the 1:2:600 bordeaux mixture one time, and bordeaux mixture consists of: copper sulphate 1 weight portion, lime 2 weight portions, water 600 weight portions.

The present invention has good control efficiency through field trial to Pricklyash Ruct.

Embodiment

Investigate through actual, prove that its occurring degree correlative factor comprises:

Land occupation condition: tailo is light, and Schattenseite is heavy.

Planting environment: ventilation and penetrating light is bad, a kind long-stalked crop, and morbidity is serious.

Kind: clovershrub is heavy, the beans green pepper, and the dog green pepper is light.

Cultivation condition: scattered green pepper tree is light, and the green pepper tree is heavy in flakes.

For above characteristics, Adopts measure comprises:

1, artificial control's way

1. the germ that survives the winter is eliminated in clear garden.

2. strengthen rich water quality management, strengthen tree vigo(u)r.

3. cultivate disease-resistant variety, with the clovershrub companion planting.

2, chemical control way

1. at the beginning of 6 months-and late July, with Tebuconazole (or triazolone, propiconazole) 600-800 times liquid spraying.

2. behind the fruit harvesting, before germinate spring, each sprays a 1:2:600 bordeaux mixture (1 jin in copper sulphate, 2 jin in lime, 600 jin in water).

Claims (1)

1. Pricklyash Ruct is prevented and treated method, it is characterized in that comprising following measure:
