Beta-cypermethrin is a pyrethroid insecticide with high biological activity, and it is a high-efficiency isomer of beta-cypermethrin, which has contact toxicity and stomach toxicity. Wide insecticidal spectrum, fast knockout speed and higher insecticidal activity than cypermethrin. It is suitable for controlling pests and sanitary pests on cotton, vegetables, fruit trees, tea, trees and other plants.
1, cotton aphid, thrips: control when the aphid plant rate reaches 30% or the leaf-rolling plant rate reaches 5%. Use 30-50ml of 4.5% EC per mu, add 40-50kg of water and spray evenly.
2. Cotton Orioles and Red Orioles: Apply pesticide at the peak of the second and third generation cotton eggs. Use 30-50ml of 4.5% EC per mu, add 40-50kg of water and spray evenly.
3. Pieris rapae and Lepidoptera minor: the larvae are controlled at 2-3 years old, and 20-40ml of 4.5% emulsifiable concentrate is used per mu, and 40-50kg of water is added, and sprayed evenly.
4. Vegetable aphid: In the peak period of wingless aphid occurrence, 20-30ml of 4.5% EC is used per mu, 40-50kg of water is added and sprayed evenly.
5. Citrus leaf miner: control in the early stage of bamboo shoots and the peak period of egg incubation. Dilute with 4.5% emulsifiable concentrate and water for 2,250-3,000 times per mu, and spray evenly.
6, citrus red wax scale: control in the peak of egg incubation. Dilute 900 times with 4.5% EC water and spray evenly.
7. Ectropis obliqua: Apply pesticide at the peak of 2-3 instar larvae, with 25-40ml of 4.5% emulsifiable concentrate per mu and 60-75kg of water, and spray evenly.
8. Bemisia tabaci: Apply the pesticide at the 2nd-3rd instar larval stage, with 25-40ml of 4.5% emulsifiable concentrate per mu, 60-75kg of water, and spray evenly.
9. All kinds of Dendrolimus punctatus, Dendrolimus punctatus and Hyphantria cunea: During the emergence period of 2 ~ 3 instar larvae, 4,000 ~ 8,000 times of 4.5% EC was used for spraying, and the amount of aircraft spraying was 60 ~ 150ml per inclination.
10. sanitary pests: to control adult mosquitoes and houseflies, use 0.2-0.4g of 4.5% wettable powder per square meter, dilute it 250 times with water, and spray it for retention. To control cockroaches, use 0.9 g of 4.5% wettable powder per square meter in cockroach habitats and activity places, dilute it with water 250 to 300 times, and spray it for retention. To control ants, use 4.5% wettable powder 1. 1-2.2g per square meter, dilute it with water for 250-300 times, and carry out retention spraying.
Applicable crops
Beta-cypermethrin is a broad-spectrum insecticide with high insecticidal activity against many pests. It can be used for all kinds of fruit trees, vegetables, grains, cotton, camellia oleifera and other crops, as well as all kinds of trees, plants, tobacco budworm, cotton bollworm, diamondback moth, beet armyworm, Spodoptera litura, tea geometrid, red bollworm, aphid, liriomyza sativae, beetle, stinkbug, psyllid, thrips, moth eater and leaf curl moth.
use technology
Beta-cypermethrin is mainly used for spraying to control various pests. Generally, 4.5% dosage form or 5% dosage form is mixed with 1500-2000 times liquid, or 10% dosage form or 100 g/L EC is mixed with 3000-4000 times liquid, which has the best spraying effect in the early stage of pest occurrence.
Matters needing attention
Beta-cypermethrin has no systemic effect, so it must be sprayed evenly and thoughtfully. The interval of safe recovery is generally 1 0 days. It is toxic to fish, bees and silkworms, and cannot be used in bee farms, mulberry fields and their surrounding areas. It is necessary to avoid the pollution of fish ponds, rivers and other waters by liquid medicine.
