There are many insect pests that can be controlled by acetamiprid, such as cucumber aphids, whitefly, and dried pests. For different pests and diseases, the configuration method of acetamiprid is different. Let's follow the small series to understand.
1. Cucumber aphids are applied in the early stage of aphid, with 3% emulsifiable concentrate 40~50mL/667m2, water 60~75L, evenly sprayed, which has good control effect on melon. In rainy years, the efficacy can last for more than 15 days.
2. Apple aphids are applied in the growth stage of apple tree shoots and in the early stage of rapid growth of aphids. Spray with 3% EC 2 000 ~ 2 500 times, or spray 40 ~ 50 mL per 100 L water, it is quick-acting to aphids and resistant to rain. Scour, the duration of the effect is more than 20 days.
3. Citrus aphids are sprayed and controlled in the occurrence of aphids, using 2-3 emulsifiable concentrates of 2,000 to 2,500 times, or 40 to 50 ml of 3% emulsifiable concentrate per 100 liters of water. Spray, has excellent control effect on citrus aphids and long-lasting effect, and has no phytotoxicity to citrus at normal dosage.
4. When the whitefly is in the early stage of the population and the insect population density is still low, it is sprayed with 3% emulsifiable concentrate of 000 to 2,000 times. Due to the overlapping of the insects, each insect state exists at the same time, and it is impossible to kill all the insect states in one dose, and it is necessary to continuously control several times.
5. Leafhopper, hummer, hibiscus, etc. spray with 3% emulsifiable concentrate 2,000 to 2 500 times, or 5% emulsifiable concentrate 5,000 to 10,000 times liquid spray, or 20% soluble powder 8,000 to 10,000 times liquid spray .
6. Light-shouldered star-shaped beetle, pink-necked beetle and other dry pests can be injected into the tree with a diameter of l. 8 ~ lmL per plant.
