A vitamin salt is a kind of high efficiency and low toxicity, low residue, pollution-free biological insecticide, with a wide spectrum of insecticides, long effective period, a variety of pests and mites have a good control effect, deeply liked by farmers, is currently the largest sales of insecticides, but A vitamin salt has a disadvantage, that is, poor quick-activism, pest resistance is strong, generally after 3 to 4 days of application, in order to kill pests, many farmers mistakenly think that the insecticidal effect is not good. In fact, only one drug needs to be added, and the quick-acting effect will be improved immediately, and the duration of the effect will be longer. This medicine is highly effective cypermethrin.
Insecticidal mechanism of methylphenidate
Mevin salt to contact killing and gastric toxicity is the main, the agent into the insect body, can enhance the role of pest nerves, disturb nerve conduction, irreversible paralysis occurs, larvae stop eating immediately after contact, in 3-4 days to reach the highest fatality rate. After being absorbed by crops, the methyl salt can not fail in the plant for a long time, and after being eaten by the pest, a second insecticidal peak occurs after 10 days, so the effectiveness of the methyl salt is longer.
Insecticidal mechanism of highly efficient cypermethrin
High-efficiency cypermethrin is a permethrin insecticide, with contact killing and gastric toxicity, pests after contact with the agent, through the combination of sodium ions in the body of the pest, damage the nervous system of the pest, the pest can not eat, and eventually lead to death. It has the characteristics of good quick effect, fast knockdown speed, wide range of pest control and cheap price.
The main characteristics of high chlorine + methyl vinyl salt
(1) Good quick-activism: the synergistic effect after compounding is very significant, it can quickly knock down pests, and it takes 3 to 4 days to kill pests with a single dose, and after compounding, pests can be killed on the same day.
(2) The insecticidal spectrum is wider: Beavita salt is mainly used to control Lepidoptera and Diptera pests, such as red-banded leaf curl moth, smoke aphid nocturnal moth, cotton bollworm, tobacco moth, small cabbage moth, armyworm, beet nocturnal moth, grassland nocturnal moth, pink nocturnal moth, kale silver nocturnal moth, vegetable powder butterfly, cabbage heart borer, kale horizontal striped borer, tomato moth, potato beet, Mexican ladybug and other pests, and after compounding, it can also control aphids, blind aphids, pear wood lice, borer shell insects and other pests. In particular, the prevention effect of pests such as dihua borer, triple borer, large borer, drill heartworm, small cabbage moth, beet nocturnal moth, smoke green insect, aphid and so on is outstanding.
(3) Cheap price: the price of methyl vitamin salt is higher, single dose use, due to the gradual enhancement of pest resistance, the dosage gradually increases, the cost is also very high, after the addition of high-efficiency cypermethrin, the dosage does not need to increase, the control effect will be significantly improved, can greatly reduce costs.
(4) Long effectiveness: After the compounding of methylhydrate salt and high chlorine, not only the quick availability is improved, the characteristics of secondary insecticide will be better, and the effectiveness period will be longer.
Suitable for crops
After the two are compounded, the safety is good, and it can be widely used in cabbage, kale, cauliflower, radish, tomato, pepper, cucumber, apple, pear tree, pomegranate, guava, star fruit, lychee, longan, Chinese herbal medicine, flowers, etc.
How to use
To control pests such as cabbage, kale, cauliflower, tomato, pepper and other vegetables, beet noctus moth, twill moth, cabbage moth and other pests, 4.5% high-efficiency cypermethrin emulsion 1000~1500 times liquid + 1% methyl vitamin salt emulsion 2000~2500 times liquid can be used to spray evenly.
To control heartworms, aphids and other pests on apple, pear, peach and other fruit trees, 4.5% high-efficiency cypermethrin emulsion 1500 times liquid + 1% methyl vitamin salt emulsion 2000 times liquid can be used to spray the whole plant evenly.
Description: The compounding of methyl vitamin salt is very good, and it can also be compounded with various pesticides such as insect mite nitrile, flulling urea, indicolide, methoxyhydrazide, sullicide and other pesticides, which have a good synergistic effect, and can be used alternately when controlling pests, and the control effect is better.
