Do Different Specifications of the Anti-insect Netting Have Any Impact on Plant Growth？

In recent years, with the increasing application of pesticides and chemical fertilizers, food pollution has become increasingly serious. To this end, more pollution-free production technologies have been explored, and insect nets are one of them.

1. Specifications of Anti-Insect Nettings

Common insect nets generally have the following specifications: 20 meshes, 30 meshes, 40 meshes, 60 meshes, 80 meshes, and 100 meshes. The larger the value, the denser the mesh.

(Ps. The specifications of the insect net can also be adjusted according to the required size.)

2. The Impact on Plant Growth

2.1  Effect of Pest Control

Different mesh insect nets have different control effects on insect pests. The more mesh, the better the insect control effect.

For example, the control effect of 20, 40, and 60 mesh insect control nets for diamondback moths all reached more than 90%, which is due to the large size of the diamondback moths. But for vegetable aphids, a 60-mesh insect net is more suitable than the previous two, because the latter has a smaller body and requires a denser mesh to block it.

2.2 The Impact on yield

Planting needs to take into account the needs of light, temperature, humidity, and other elements.

Studies have shown that the pore size of insect nets can affect the growth of plants. The smaller the mesh number is, the larger the pores of the insect control net are. Therefore, the pest control effect is poor for small insects, and the resistance to rain wash is also small; the larger the mesh number, the smaller the pores of the insect control net. Although the effect of preventing small pests and resisting rain wash is good, it will lead to serious shading and temperature rise in the net, and the plants will appear yellow, withered, and other undesirable phenomena.

It can be seen from this that the choice of the anti-insect netting is not the smaller the mesh, the better the effect. According to the plant's own needs - pest control, temperature and humidity, light, etc. - it is best to select the appropriate specifications.
