Ethyl polybactericide is a new type of multi-fungicide insecticide developed by Dow Yinong Company, ethyl polymycin is an analogue of polycycline, it is more broad-spectrum than polycycline, better anti-effect on armyworms, higher control effect on apple beetle moth, pear yellow lice, etc., longer shelf life. Biological activity can be comparable to indoxate, methylvitamin salt and so on.
First, the mechanism of action
The mechanism of action of ethyl polybactericide 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.
Second, the main features
Polybactericide is a broad-spectrum biological insecticide, insecticidal activity far exceeds organophosphorus, carbamate, cyclopentadiene and other insecticides, fast-acting, long shelf life, rain-resistant erosion, low toxicity to humans and mammals, no chronic toxicity. It is lowly toxic to birds, fish, earthworms and aquatic plants; in practical applications, it is virtually non-toxic to bees.
3. Scope of application
Ethyl polybactericides can be used to control important pests on high-value fruits, vegetables, nuts and grapes, especially for difficult pests such as apple moths.
4. 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.
5. How to use
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.
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 and small cabbage moth, in the early larval stage, per 667 square meters with 2.5% ethyl polybactericide suspension 50-100 ml of water spray, evening application effect is the best.
