Problems solved by technology

However, the use of these methods has its own limiting factors, and there are loopholes in prevention and control, so that tomato whitefly damage occurs in large areas in greenhouse planting areas in different regions every year, and at the same time, the risk of pesticide residues is caused by improper use of chemical pesticides.

Embodiment 1

[0018] The embodiment of the present invention provides a method for preventing and controlling greenhouse tomato whitefly by using a photosynthetic high-fat film agent, including a photosynthetic high-fat film agent, and the photosynthetic high-fat film agent is composed of the following components by weight ratio: 200 parts of dodecyl alcohol, 50 parts of cetyl alcohol, 10 parts of emulsifier, 5 parts of co-emulsifier, 40 parts of thickener, and 800 parts of water; after diluting the photosynthetic high-fat film agent with water, the greenhouse tomato is sprayed, including the following steps:

[0019] A1: At the seedling stage, before the disease appears, dilute the photosynthetic high-lipid film agent with water to 800 times, and spray the tomato every 10 days; in case of high temperature, increase the dilution multiple and spray to prevent leaf burns. Be sure to be careful, even and thoughtful when spraying, so that a layer of film is adhered to the surface of the plants t...

Embodiment 2

[0030] Biological activity observation

[0031] Refers to the effect of controlling whitefly in greenhouses. The photosynthetic high-lipid film agent was tested on tomatoes grown in greenhouses. The control group was purchased from the market with the pesticide acetamiprid, and the usage was used according to the instructions on the product label. Calculated as follows:

[0032]

[0033] In the formula:

[0034] PT——control effect, unit is percentage (%)

[0035] PT 0 ——the number of pre-medicated insects in the chemical treatment area, the unit is head;

[0036] PT 1 ——the number of worms in the chemical treatment area, the unit is head;

[0037] CK 0 ——the number of living insects in the blank control area before spraying, the unit is head;

[0038] CK 1 ——The number of living insects in the blank control area after spraying, the unit is head.

Abstract

The invention provides a method for preventing and controlling greenhouse tomato whiteflies in a greenhouse by using a photosynthetic high-fat film agent. The method is characterized by adopting the photosynthetic high-fat film agent, wherein the photosynthetic high-fat film agent is prepared from, by weight, the following components: 200 parts of dodecanol, 50 parts of hexadecanol, 8 parts of anemulsifier, 5 parts of a co-emulsifier, 40 parts of a thickener and 800 parts of water. After the photosynthetic high-fat film agent is diluted by adding water, greenhouse tomato crops are sprayed. The method for preventing and controlling tomato whiteflies in the greenhouse by using the photosynthetic high-fat film agent has the advantages of being simple, high in efficiency, environmentally friendly and free of pollution, and has the promotion effects of improving the quality of tomatoes and guaranteeing the quality of tomatoes and selling the tomatoes in advance.

Description

technical field [0001] The invention relates to the technical field of agricultural plant protection, in particular to a method for preventing and controlling whitefly on tomato in greenhouses by using a photosynthetic high-fat film agent. Background technique [0002] Tomato originates in South America and is widely cultivated in the north and south of my country. Tomato fruit is rich in nutrition and has a special flavor. Can be eaten raw, cooked, processed tomato paste, juice or whole fruit canned. But in the process of greenhouse tomato cultivation, it will be damaged by whitefly. [0003] Whitefly is also known as whitefly. Belongs to Hemiptera whitefly family. It is a worldwide pest that occurs all over my country and is an important pest of crops grown in greenhouses. It has a wide range of hosts, including cucumbers, kidney beans, eggplants, tomatoes, peppers, wax gourds, beans, lettuce, cabbage, celery, green onions, peonies, etc. There are 653 species of plan...
