Problems solved by technology

However, in production practice, when field operators come in and out, it is very easy to bring insects or eggs into the field, or when people come in and out, bemisia tabaci fly into the field, and the reproduction speed is fast, which leads to the waste of previous prevention efforts
[0004] Breeding disease-resistant varieties is currently the most effective way to control tomato yellow leaf curl virus, and it is also the most successful technical solution at present. However, this solution brings difficulties to breeding, and many materials that are not resistant to yellow leaf curl virus must be Transplanting into disease-resistant materials is time-consuming and labor-intensive, requires a large initial investment, and there are many failures in breeding

Embodiment 1

[0026] A method for preventing tomato yellow leaf curl virus disease. Planting non-toxic tomato seedlings in two large sheds A and B, the two sheds are separated by 500 meters, 200 plants per shed, with an area of ​​66.7 square meters per shed, and then placed in the same belt Two tomato seedlings with poisonous insects and 20 jute plants were treated with A to open all the surroundings of the greenhouse, and for treatment B, they were isolated from the outside with 40 mesh gauze around the greenhouse to observe the disease.

[0027] deal with Number of diseased plants in 20 days Number of diseased plants in 40 days Number of diseased plants in 60 days A000 B0105200

[0028] In this example, treatment A shows that Bemisia tabaci does not like the smell of jute and escapes from the surroundings of the greenhouse. Although greenhouse A has a poison source, there is no vector, so there is no disease. Treatment B shows that the smell of jute is not fatal to Bemisia tabaci It can o...

Embodiment 2

[0030] A method for preventing tomato yellow leaf curl virus disease. The method is to plant jute in tomato planting areas. Specifically, the tomato planting area is an open field. 2-3 days before transplanting, first clean up all the toxin sources on the open field where the tomatoes are to be planted, including weeds, dead branches, etc., and then transplant the jute and the tomatoes at the same time. In the open field, the jute is evenly distributed in a star-like shape between the gap rows of tomatoes on the open field. The density of the jute is based on reaching the tomato planting area without new virus infection. The planting ratio of tomato to jute used in this embodiment is 6:1. After this prevention method, it has a good preventive effect on the drug-resistant Q-type Bemisia tabaci, and the tomatoes in the tomato planting area basically have no disease and do not affect the normal production.

Embodiment 3

[0032] A method for preventing tomato yellow leaf curl virus disease. The method is to plant jute in tomato planting areas. Specifically, the tomato planting area is an open field. 2-3 days before transplanting, first clean up all the poison sources on the open field where the tomatoes are to be planted, and plant the jute in the flower pots and place them in the open field. During the operation, the flower pots for planting jute are moved out of the field, and after the field operation is completed, the flower pots for planting jute are moved into the field. The flower pots for planting jute are evenly distributed among the rows of tomato gaps on the open ground. The density of jute is based on reaching the tomato planting area without new virus infection. The planting ratio of tomato to jute used in this embodiment is 10:1. After this preventive method, the tomatoes in the tomato planting area basically do not get sick and do not affect the normal production.

Abstract

The invention discloses a method of preventing tomato yellow leaf curl virus disease. The method includes the step of planting jute in a tomato planting area and / or surroundings thereof, so that the virus transmission route is interrupted and the occurrence of tomato yellow leaf curl virus disease is prevented. The invention opens up a new way of preventing tomato yellow leaf curl virus disease, the operation is very simple and effective, the cost is small, and the method is easy to popularize.

Description

Technical field [0001] The invention relates to a method for preventing and controlling tomato diseases, in particular to a method for preventing tomato yellow leaf curl virus (TYLCV). Background technique [0002] Plants infected with tomato yellow leaf curl virus are dwarfed, grow slowly or stagnant, the top leaves are often slightly chlorotic, yellow, and smaller, the edges of the leaves are rolled up, the leaves are thickened, and the texture of the leaves becomes hard. The veins on the back of the leaves often appear purple. In the early stages of growth and development, the infected plants were severely dwarfed and could not bloom normally. In the late stage of growth and development, only the upper leaves and new buds of the infected plants show symptoms, the number of fruit is reduced, the fruit becomes smaller, and the fruit is unevenly colored (red and impermeable) at the mature stage, and basically loses its commercial value. [0003] At present, the main method of prev...
