Sticky yellow plate suspension height is very important

The yellow moldworm is a low-cost, better-effect physical insecticide used in modern agriculture. It is a physical control technology that uses insect coloration to trap agricultural pests. In order to exert the green prevention and control effect of the yellow body of the sticky insect, it is very important to use it correctly, and the hanging height of the yellow board of the sticky insect is very important.

The height of the yellow stalk of the armyworm is different, so the killing effect of the pest is different. Generally speaking, the height of the suspension should be adjusted with the increase of the plant. For example, when the vegetable is in the seedling, the height of the yellow plate should be higher than the seedling 10-15 cm. When the height of the plant is close to the sticky board, the sticky board It should be adjusted as the plant height increases; when setting the blue board, the suspension height should be the same as the crop.

In addition, in different seasons, the suspension height of the yellow smear may also be different, which is set according to the activity characteristics of the pest. For example, in the low temperature season in winter, the light and temperature in the upper part of the plant, especially near the growth point, are very suitable, and the pests mostly feed on the young parts of the growth point, so the sticky board should be hung near the growth point. In the summer high temperature and strong light season, the pests are concealed in the cool places between the plants for feeding. Therefore, most of the sticky insect boards should be placed at a position about 15 cm below the growth point between the plants. The sticky insect board can be fixed with bamboo poles or directly suspended on the sling.

In short, although the use of the yellow smear is very simple, it can only exert its proper effect if it is used correctly. It can help the production of vegetable planting bases, tea gardens, etc. by reasonably setting the height and quantity of the yellow smear. The site will better carry out the green prevention and control work of pests, and provide strong support and protection for the creation of green pollution-free production bases. For large-scale planting sites, it is also possible to combine other physical control devices such as solar insecticidal lamps to achieve a multiplier effect.
