Embodiment Construction

[0012] The experimental site is Jianxin Village, Farm Town, Xiuwen County, Guizhou Province, with an altitude of 1270 meters. The soil type is Chaomu field, and the previous crop is rapeseed, with a medium fertility level. The tomato variety is Hongfu No. 8, the plant spacing is 56cm, the row spacing is 65cm, and there are 1900-2000 plants per mu. The test plots are randomly arranged, each plot is 20m 2 , repeat 3 times. Use a knapsack sprayer to spray stems and leaves, apply 50 kg of pesticide solution per mu, and apply pesticides 3 times at intervals of 10 days.

[0013] The experimental design concentration is:

[0014] Treatment (1) 200 times solution of borax;

[0015] Treatment (2) 300 times liquid of 0.5% chitosan aqueous solution;

[0016] Treatment (3) 20% morpholine hydrochloride · copper acetate wettable powder 300 times liquid;

[0017] Treatment (4) 100 times solution of borax, 100 times solution of 0.5% chitosan aqueous solution and 100 times solution of 20%...

Abstract

The invention discloses a method for preventing tomato virus diseases, wherein borax 100-300 times liquid, 0.5% chitosan agent 100-300 times liquid, 20% moroxydine hydrochloride.copper acetate wettable powder 100-500 times liquid are sprayed to stems and leaves after being uniformly mixed with each other, and tomato plants are uniformly sprayed for one time every 10 days, and are sprayed for three times together, thereby being capable of achieving obvious prevention effects. The method for preventing the tomato virus diseases is safe and innocuous for growth of tomato plants and tomato fruits, reduces yield loss, has the advantages of simple operation, low prevention cost and excellent prevention effect, is easy to generalize, and brings great profits for vegetable growers.

Description

technical field [0001] The invention relates to a method for preventing and treating tomato virus diseases, and belongs to the technical field of vegetable disease prevention and control. Background technique [0002] Tomato (Tomato) is a herbaceous plant of the genus Tomato in the family Solanaceae. It is one of the most important vegetables in our country. important position. With the increase of cultivated varieties, the expansion of planting area and the diversification of planting methods, the occurrence of tomato diseases and insect pests is becoming more and more serious. The main diseases in the tomato production process in my country include tomato virus disease, gray mold, late blight, bacterial wilt, fusarium wilt, etc. Tomato virus diseases, especially tomato mosaic virus disease and cucumber mosaic virus disease, occur in protected areas in my country It is especially common and has become one of the most serious diseases in tomato production in protected areas...
