Insect netting is a net used to protect vegetables, fruits, and flowers from damage caused by insects.
By using insect netting, it is possible to reduce the use of pesticides and to grow healthy and safe crops without pesticides. However, since there are many types of insect netting, including fineness of mesh, color, and reflectivity, it is important to use a product that is appropriate for the size and characteristics of the insects to be controlled.
Insect netting is used as a tunnel covering in open field cultivation, as well as on the sides, skylights, and openings of greenhouses. In particular, it is an indispensable material for pesticide-free and pesticide-reduced cultivation.
For example, cruciferous vegetables, such as cabbage and broccoli are known to be susceptible to pest damage from caterpillars, yarrow weevils, aphids, and stink bugs. Insect damage to vegetables is often caused by larvae, but insect netting can prevent adult insects from flying in and laying eggs.
Features of insect netting are that while it prevents insects of a certain size from entering, it does not easily interfere with the growth of vegetables, fruits, flowers, etc., because it is made with ample light, air, and moisture permeability.
The advantage of insect netting is that, once installed, the netting is effective for a long period until it deteriorates. In addition to damage from insects, it can also be effective in protecting crops from rain and wind. Another advantage is that water can be sprayed from the top of the net.
Insect netting can also be used in tunnel and greenhouse cultivation to prevent damage from insects.
In order to protect crops from insect netting, it must be put up before the adult insects fly over. Also, gaps in the net will allow pests to enter, so the net must be carefully stretched without gaps.
Please note that if the timing of putting up insect netting is delayed, the pests will not be able to get out, and a large infestation may occur. The timing of pest outbreaks differs slightly from region to region, so be sure to obtain accurate information.
Although insect netting provides light permeability and breathability, it can attract muck and mold depending on the growing environment, so it is important to keep a close watch on the netting.
Insect netting is usually made of white polyethylene, but there are also red-colored products (which insects do not like) and types with silver thread are available. There are also various types of nets for households and agriculture, in terms of mesh size (mesh size), color, length, and so on.
Insect netting is available in mesh sizes ranging from as small as 0.25 mm to as large as 4 mm and is capable of blocking the entry of insects. The finer the mesh, the better the netting is able to block the entry of minute insect pests, but the permeability and air permeability are slightly reduced.
|0.4 mm||Thrips, whiteflies, ladybugs, tobacco moths, spider mites, and stink bugs|
|0.6 mm||Leafhoppers and leafhoppers|
|1.0 mm||Weevils, caterpillars, and leafhoppers|
|2 to 4 mm||Whiteflies and green lacewing moths|
Using insect netting of the appropriate size for the pest will minimize the amount of labor required to remove insects. Note, however, that the rust mite, which sucks the juice of fruits such as apples and mandarin oranges and vegetables, is small (about 0.1 mm in length) and cannot be protected with insect netting.
A new type of insect netting for greenhouse cultivation is now available that contains a long-lasting chemical. Since the amount of chemical used is not insecticidal, but just enough to make it difficult for pests to come close to the net, dead insects do not get stuck in the mesh and ventilation inside the greenhouse can be maintained.
Since the product contains chemicals, it cannot be used for sticky rice cultivation or tunnel cultivation, where it is in direct contact with the crop. Even in greenhouse cultivation, it is best not to use this product if you are committed to pesticide-free cultivation.
The types and sizes of pests that are likely to be attracted to crops vary depending on the type of crop. When selecting an insect netting, it is important to know in advance the size of the pests that will damage your crops, and choose an insect netting with a smaller mesh than the size of the pests.
In addition, insect netting should be properly applied prior to the outbreak of pests to prevent infestation.
