1. Hanging time: use from seedling stage and planting stage to maintain uninterrupted use and effectively control the development of pests.
2. Hanging quantity: in the early stage of prevention and control, 3-5 pieces of armyworm board can be hung per mu in greenhouse or open field to detect insect density. When the amount of lure on the armyworm board increases,
20*10cm
Fruit tree each 2 pieces, insect density peak can increase the number of armyworm board
3. Hanging method: wire through the two hanging holes of armyworm board, fixed it, hanging on the hanging rope in the greenhouse or the branches of fruit trees in the orchard: in the open environment, the upper split bamboo clip the middle of the armyworm board, and then inserted into the underground fixed; Or insert the supporting frame of the armyworm board in the ground, and then fix the two hanging holes of the armyworm board on the supporting frame.
4. Hanging position: for low raw vegetable crops, the hanging height should be 10-15cm from the upper part of the crop, which can be adjusted according to the actual height of the crop; On the rack vegetables should be along the line, so that the armyworm board vertical hanging in the middle of two lines of plants in the upper part or the upper part; For fruit trees, it can be hung directly from branches with sparse leaves.
5. Post-treatment: When the number of sticky pests on the board is large, use hacksaw blade or wood and bamboo slices to scrape off the insect body in time, which can be reused and has a better effect in the greenhouse.
