Control method of Zanthoxylum bungeanum rust disease

Abstract

The invention discloses a control method of the Zanthoxylum bungeanum rust disease and belongs to the field of forest pest and disease control. According to the method, a Zanthoxylum bungeanum tree is trimmed in winter, dead branches and fallen leaves are cleared, a garden is disinfected, an overwintering protective agent for the Zanthoxylum bungeanum tree is prepared for root-irrigating treatment, and then, the overwintering protective agent for the Zanthoxylum bungeanum tree is diluted with water for 10-100 times and then sprayed to the tree; (2) in the middle ten days of May in the next year, a Zanthoxylum bungeanum rust disease preventive is prepared, sprayed to the tree 2-3 times and sprayed once every other 10 days; disease spots are removed once found, attapulgite powder, 80% mancozeb wettable powder and 50% carbendazim wettable powder are added to the Zanthoxylum bungeanum rust disease preventive and mixed uniformly, and an agent is prepared and sprayed and / or irrigated to roots 2-4 times and sprayed and / or irrigated once every other 4-6 days. By means of the method, the Zanthoxylum bungeanum rust disease can be prevented, the Zanthoxylum bungeanum tree can be inhibited from suffering from the rust disease, pathogenic bacteria of the Zanthoxylum bungeanum rust disease can be killed, the effect is remarkable, and the yield and the quality of Zanthoxylum bungeanum are improved.

Description

technical field [0001] The invention belongs to the field of prevention and control of forest diseases and insect pests, in particular to a method for preventing and treating pepper rust. Background technique [0002] Chinese prickly ash (scientific name: Zanthoxylum bungeanum Maxim.) is a small deciduous tree of Rutaceae, Zanthoxylum genus, up to 7 meters high; thorns on the stem, short thorns on the branches, and pubescent branches in the current year. Leaf rachis often have very narrow leaf wings; leaflets are opposite, ovate, elliptic, sparsely lanceolate, with finely cracked teeth on leaf margins, and oil spots between teeth. The back of the leaf is pilose, and the back of the leaf has reddish-brown markings. Inflorescences terminal or on top of lateral branches, tepals yellow-green, roughly the same shape and size; style obliquely dorsiflexed. The fruit is purple-red, with scattered slightly raised oil spots. The flowering period is April-May, and the fruiting period...

Problems solved by technology

[0003] Pepper rust causes a large number of pepper leaves to fall off after picking peppers, which affects the accumulation of nutrients in the current year. When the weather warms up, secondary buds will germinate and consume nutrients, thus affecting the yield and quality of the next year.
