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.
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%.
