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 fruit fly damage occurs in large areas in different bitter melon production areas every year, and at the same time, the risk of pesticide residues is caused by improper use of chemical pesticides.

Embodiment 1

[0020] The invention provides a method for preventing and controlling bitter gourd fruit flies by using a photosynthetic high-fat film agent, which comprises a photosynthetic high-fat film agent. 150 parts, 30 parts of repellents, 8 parts of emulsifiers, 3 parts of co-emulsifiers, 40 parts of thickeners, and 800 parts of water; after utilizing the photosynthetic high-fat film agent to add water to dilute, bitter gourd is sprayed, comprising the following steps:

[0021] A1: At the seedling stage of bitter gourd, after diluting the photosynthetic high-lipid film agent with water 600 times, spray the bitter gourd every 12 days; during this period, the amount of pesticides and chemical fertilizers can be reduced or some pesticides, chemical fertilizers, foliar fertilizers, hormones, etc. can be replaced.

[0022] A2: At the bud stage of bitter gourd, after diluting the photosynthetic high-lipid film agent with water 500 times, spray the bitter gourd every 9 days; at the same time,...

Abstract

The invention provides a method for preventing and controlling balsam pear drosophila melanogaster by using a photosynthetic high-fat film agent. The photosynthetic high-fat film agent is included, and is prepared from, by weight, 150 parts of a dodecyl alcohol, 150 parts of a cetyl alcohol, 30 parts of a repellent, 8 parts of an emulsifier, 3 parts of a co-emulsifier, 40 parts of a thickener and800 parts of water; after being diluted with water by using the photosynthetic high-fat film agent, balsam pears are sprayed. The method can effectively reduce the invasion of the drosophila melanogaster, the time for the repellent to remain on the balsam pears can achieve a sustained effect, and the effect of preventing the drosophila melanogaster is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural plant protection, in particular to a method for preventing and controlling bitter melon fruit flies by using a photosynthetic high-fat membrane agent. Background technique [0002] Bitter melon is native to East India and is widely cultivated in tropical to temperate regions of the world. It is widely cultivated in the north and south of my country. Bitter gourd tastes sweet and bitter. It is mainly used as a vegetable and can also be candied. Ripe pulp and arils are also edible. However, after the bitter gourd blooms and bears fruit, it is often damaged by fruit flies. [0003] Drosophila is an important pest of tropical and subtropical melons, vegetables and fruits in my country. It has strong fecundity and wide range of hosts, and its damage can be seen all year round, causing major economic losses. It is also an important pest in the international trade of agricultural products; only b...
