1. The trapping pots are installed in fields that are planted with cruciferous crops such as cabbage, cauliflower, cabbage, greens, kale, and radish.
2. Two traps per acre are placed, and the distance between the basin and the basin is to be kept substantially equally. The pots should be solid, and the adjacent plots should take care of each other and should not be too concentrated.
3. The lure is located in the middle of the 1-2 cm above the bowl surface, and the lure is fastened with thin iron wire. The thin wire is fixed on both sides with foam and put into the basin, one for each pot.
4. Pour clear water into the basin. The water level is 1~2cm below the pot mouth. A small amount of detergent may be added to the pot to increase the trapping effect.
5. The surface of the bowl is always 10 to 20 cm above the vegetable surface. The field can use cement bricks to trap pots. Every 1-2 days, salvage the moths in the pot. Frequently add water or replace fresh water. Temporary replacement lures are generally replaced 30 to 40 days.
Second, the matters needing attention
1. Place the trapping pots in the field and lay them out in a checkerboard arrangement.
2. Avoid non-cruciferous crops such as garlic and celery that have a repellent effect on adults of Plutella xylostella.
3. In order to avoid the trapping pots being fixed at the same position for a long time and causing the behavior of the diamondback moth to warn and seek help, the trapping effect should be moved in a certain direction each month.
