What is methylaminoavermectin benzoate?

What is methylaminoavermectin benzoate? How to use methylaminoavermectin benzoate? Netizens are also asked to help introduce a residue-free and pollution-free biological pesticide: methamectin benzoate, which is commonly used in vegetables, melons and fruits, fruit trees, field crops and other crops. But what exactly is methylaminoavermectin benzoate and how to use it? There are many netizens do not know very well, so the farming network collated the information and usage of methamectin benzoate, the following detailed list for netizens' reference. The effect of Emamectin benzoate: Emamectin benzoate is a non-residue and pollution-free biological pesticide. It has extremely high activity to larvae of Lepidoptera insects and many other pests and mites. It has both stomach toxicity and contact effect. It has a good effect at very low dose (0.084~2g/ha), and has no harm to beneficial insects in the process of pest control. It is beneficial to the integrated control of insect pests, expands the insecticidal spectrum and reduces the toxicity to humans and animals. Methylaminoavermectin benzoate can enhance the effect of neuroticism such as glutamate and gamma-aminobutyric acid (GABA), thus making a large amount of chloride ions into nerve cells, causing loss of cell function and disrupting nerve conduction. Larvae stop eating immediately after contact, resulting in irreversible paralysis, reaching the highest fatality rate within 3-4 days. Because methylaminoavermectin benzoate binds closely to soil and does not accumulate in the environment, it can be transferred by Translaminar movement, which is easily absorbed by crops and infiltrated into the epidermis, so that crops have a long-term residual effect. The second peak of insecticidal mortality occurred in more than 10 days, and it was rarely affected by environmental factors such as wind and rain. Emamectin benzoate can control pests: Emamectin benzoate has incomparable activity to many pests, especially to Lepidoptera, Diptera and thrips. Such as red belt leaf roll moth, tobacco aphid armyworm, cotton bollworm, tobacco armyworm, diamondback moth, beet armyworm, dryland night moth, Spodoptera litura, cabbage moth, cabbage striped borer, tomato beetle, potato beetle, Mexican ladybug and so on. The usage of methylaminoavermectin benzoate is as follows: 1. To control cotton bollworm, leaf roll moth, leaf miner, diamondback moth, beet armyworm, Spodoptera litura and other pests. Spray 30-50 ml of water 30-50 kg / mu or 1000-2000 times per mu 2. Control red (white) spiders, spray 1.9% methylvitamin salt EC 4000-5000 times at the initial stage of occurrence; 3. Control pear planthopper, spray 1.9% methylvitamin salt EC 3000-4000 times; 4. Control leaf moths (such as Spodoptera litura). Spray 1.9% methylvitamin salt EC 3000-4000 times at the initial stage of occurrence. 5. To control Plutella xylostella, 1% EC can be used to control the diamondback moth, 10g / 12g EC, 50~60kg to water, spray evenly in the peak period of young larvae. 6. Control beet armyworm, use 1% EC 15g to 25g per mu, 50~60kg to water, spray evenly in the peak period of young larvae. 7. To control tobacco green insects, 50-75 grams of 1% EC was used per mu, and 50~60kg to water was sprayed evenly during the peak period of young larvae. Points for attention in the use of methylaminoavermectin benzoate: 1. It should not be mixed with alkaline substances. 2. Methylaminoavermectin benzoate has no internal absorption and tries to be uniform and thoughtful during spraying. 3. Methylaminoavermectin benzoate should be used in egg incubation or juvenile stage for boring and latent leaf pests. What is Fushou snail and how to make armyworm board
