The yellow smear is mainly used to control vegetables and fruit tree pests, such as mites, whiteflies, and yellow strips.
The suspension height of the yellow stalk of the armyworm is optimally 5 to 10 cm above the growth point of the crop, and the suspension height is adjusted as the crop grows.
The hanging time for controlling mites and yellow bells is generally in early April, and the hanging time for controlling white mites is generally in early May. After the emergence of vegetables and the occurrence of pests after transplanting, the yellow board of the armyworm is suspended. The earlier the better, the better the whole vegetable production period will be used.
The size of the yellow board of sticky insects is 20 cm × 30 cm, 30 sheets per mu.
Use one end of the plastic rope or wire to fix it on the scaffolding and the other end to the reserved hole on the yellow plate.
It is distributed in a zigzag shape or in parallel with the row direction. According to the experiment, the effect of the yellow-plate attracting insect in the east-west direction is better than that in the north-south direction.
When the area of ​​the sticky insect on the yellow board of the armyworm is more than 60%, the effect of the armyworm is reduced. The pests on the board should be removed or the yellow board should be replaced in time. When the stickiness of the yellow board is not sticky, it should be replaced in time.
