Apr. 23, 2021

With a service life of 4-6 years in general and up to 10 years, filet anti insect are shaped like window screens, with 

resistance to UV, heat, water, corrosion, aging and high tensile strength, non-toxic and tasteless. They have the 

advantages of shad, worth being popularized.

The Role of Greenhouse Insect-proof Nets

Greenhouse Insect-proof Nets' installation for greenhouses is very necessary,  it can play four major roles.

1. Greenhouse Insect-proof Nets can prevent insects effectively

Basically vegetables can keep from cabbage worms, diamondback moths, aphids and other kinds of insect pests.

Covered with insect-proof nets, agricultural products can effectively keep from cabbage worms, diamondback moths, 

tobacco caterpillars, striped flea beetles, daikon leaf beetles, aphids and other pests. According to the test, the 

effectiveness of the net against cabbage worms, diamondback moths, cowpea moths and American leaf miners is 

94-97%, and its effectiveness against aphid is 90%.

2. Greenhouse Insect-proof Nets can prevent disease

Virus transmission can bring disastrous consequences to greenhouse cultivation, especially aphids transmission. But 

insect-proof nets can cut off the transmission of diseases by pests, greatly reducing the incidence of viral disease, with 

about 80% control efficacy.

3. Greenhouse Insect-proof Nets can regulate the humidity and temperature of air and soil

The test showed that in July and August, covered with the 25-mesh white Insect Proof Net Cover In Greenhouse, the 

temperature in the morning and evening is the same as the open field, while the noon on a sunny day is about 1℃ 

lower than the open field. In March and April, the temperature in these nets is 1-2℃ higher than that in the open field, 

and the 5cm ground temperature is 0.5-1℃ higher than that in the open field, which can effectively protect against frost.

In addition, these nets can block part of the rain from falling into the greenhouses, reduce the humidity in the field, 

decrease the disease, and reduce the evaporation of water in the greenhouses on sunny days.

4. Greenhouse Insect-proof Nets have shading effect

The strong light in summer will inhibit the nutritional growth of vegetables, especially leafy vegetables. 

While agricultural anti insect net can play a certain role in shading and generally the shading rate of 20-22 mesh silver 

gray nets is 20-25%.
