The main dosage form is 6% suspension, 25% water dispersible granules
Mechanism of action Ethyl polybactericide Mechanism of action is to act on nicotinic acetylcholine receptors and r-aminobutyric acid receptors in insect nerves, causing the insect body to be insensitive to excitatory or inhibitory signaling responses, affecting normal neural activity until death.
Control objects are mainly used to control lepidoptera larvae, thrips and leafminers, etc., and have a good control effect on small cabbage moths, beet nocturnal moths, leafminer flies, thrips, twill noctus moths, and pod borers.
Characteristics of action
Ethyl polybactericide has gastric toxicity and touch killing effect, is more biologically active than polybactericide, has a wider insecticidal spectrum, and can be comparable with newly emerging insecticides such as indigovirus, methylphenidate, etc., with better quick efficacy, longer shelf life, and efficient control of Lepidoptera larvae, thrips and leafminer flies.
Prevention and control objects
It is mainly used for the control of lepidoptera larvae, thrips and leafminer flies, etc., and has a good control effect on a variety of pests such as armyworms, apple beet moths, pear yellow lice, small cabbage moths, beet noctus, leafminer flies, thrips, twill noctus moths, bean pod borers, rice and rice longitudinal leaf borer, dimen borer, arbutus fruit fly, cucumber American spotted fly and so on.
Use technology
1. To control armyworms, spray evenly with 2.5% ethyl polybactericide suspension 1000-1500 times liquid during the blooming period of young larvae. It can effectively control the pest of armyworms.
Thrips
2. For the prevention and control of apple beetle moth, 2.5% ethyl polybactericide suspension can be used to spray 800-1000 times liquid, and the prevention and control effect is outstanding, and the effective period can reach more than 14 days.
3. Control of beet nocturnal moth, small cabbage moth, apply medicine at the young larval stage, use 2.5% ethyl polybactericide suspension 50-100 ml to water spray per 667 square meters, and the best effect of evening application. Use once every 7 days, 2-3 times.
Cabbage moth
4. To prevent and control thrips, the drug should be applied before the peak of thrips, and 6% multi-bactericide 1000-1500 times liquid can be used to spray evenly in the active parts of thrips.
5. The control of rice longitudinal leaf borer should be applied 1-2 times during the peak period of 1-2 year old larvae, with 6% polybactericide suspension agent 20-30 ml per mu, mixed with 30 kg of water, evenly spray the leaf surface and leaf back of the crop, and the amount of liquid per mu is 30-60 liters.
6. The prevention and control of bayberry fruit flies should be applied 7-10 days before the picking of bayberry, and 6% ethyl polybactericide suspension can be sprayed with 1500-2500 times liquid spray, and the spray should be evenly sprayed when applying.
7. For the prevention and control of leafminer flies on cowpea, when the leaf diving fly larvae on the leaves are about 1mm or the leaf damage rate reaches 10-20%, use 6% ethyl polybactericide 50 ml per mu, mix with 30 kg of water, and the leaves need to be sprayed evenly when applying.
