Fluvulurea is a benzoyl urea insecticide. It is an inhibitor of chitin synthesis, with high insecticidal and ovicidal activity, and the effect is rapid, especially suitable for the control of cotton bollworm. In addition, fluflurea is also widely used in cotton, potato and fruit trees to control a variety of coleoptera, diptera, homoptera insects, such as the control of jujube, apple, pear and other fruit trees, peach moth, leaf roller moth, moth, peach moth and other pests, as well as citrus leaf miner moth. Not effective against mites.
In addition, the broad spectrum of fluzurea is strong, can control a variety of crops of a variety of pests, has important economic and social value.
First, the mechanism of fluvulurea:
The mechanism of fluzurea is mainly to inhibit the formation of chitosan, hinder the normal molting and metamorphosis process of pests, and also inhibit the feeding speed of pests. This inhibition causes the insect to fail to grow and develop normally and eventually die. Fluzurea is a benzoyl urea insecticide, a chitin synthesis inhibitor, with high insecticidal and ovicidal activity, can quickly knock down pests, and the vast majority of animals and humans are non-toxic, but also can be broken down by microorganisms.
2. Prevention and control objects of fluvulurea:
It can control coleoptera, diptera, lepidoptera and homoptera pests on cotton and fruit trees, and has egg killing activity. Such as cabbage worm, cabbage moth, beet moth, cabbage moth, tobacco worm, cotton bollworm, golden grain moth, leaf miner moth, leaf roll moth, bridge worm, moth moth, maggot, thorn moth, caterpillar and so on. It is especially good for pests such as cotton bollworm, but ineffective for mites. For the control of cotton bollworm, red bollworm in the egg incubation period, before the young insects into the bud, the bell, with 5% cream 1500 ~ 2000 times liquid spray.
3. Applicable crops of fluvulurea:
It is suitable for the following crops: rice, cotton, citrus, orange, apricot, apple, pear, peach, etc.
4. Characteristics of fluvulurea:
1, the knockout force is strong, the insecticidal effect is faster than other acylurea, has a high contact ovicidal activity, can be used alone or mixed.
2, the application period is not strict, can prevent and control pests that have developed resistance to organophosphorus and pyrethroids. It is a benzoyl urea insect growth regulator with high insecticidal activity, wide insecticidal spectrum, strong knockout force, quick effect and so on.
Five, the use of fluvulurea:
1, the control of jujube tree, apple, pear and other fruit trees, golden grain moth, peach moth, leaf rolling moth, thorn moth, peach moth and other pests, can be in the egg hatching stage or young larval stage with 1000 to 2000 times 5% cream spray, the effect can be maintained for more than 20 days.
2, the control of citrus leaf miner moth, tick, psyllid, fly, whitefly, bud maggot, black-winged macrotermites can be used in the egg hatching stage with 1000 times 5% cream spray.
3, the control of cabbage pests (cotton bollworm, cabbage moth, beet moth, will moth) with 5% cream per mu, about 50-80 ml, uniform spray.
For the control of cabbage bean borella, cabbage worm, American spot miner, cabbage moth, silver moth, tobacco worm, use 5% cream per mu, about 60-80 ml, evenly spray.
4, the control of tea tree pests, such as inchworm caterpillar black poison moth tea orange gall mite, with 5% cream per mu, about 60-80 ml, uniform spray.
5, control sesame pests, sesame moth, pod borer, beet moth, 5% cream per mu, about 25-30 ml, uniform spray.
6, prevention and control of forest pests: (1) prevention and control of forest pine caterpillar, with 5% butter per acre, about 50-75 ml, (2) Prevention and control of forest palm tail moth, with 5% butter per acre, about 50-75 ml, spray
6. Precautions for the use of fluvulurea:
1, the leaf-eating pests should be applied in the young larval stage. Moth pests should be applied at the peak of egg laying and egg hatching. The agent has no internal absorption and permeability, and the spray should be uniform and thorough.
2, can not be mixed with alkaline pesticides. But can be mixed with other insecticides, its control effect is better.
Farmers need to pay attention to the fact that fluzurea can not be mixed with alkaline pesticides. However, it can be mixed with other pesticides, and its control effect is better, but it is highly toxic to fish and silkworms, and special care should be taken.
