What pesticides are often used in bananas?

What pesticides are often used in bananas? The following varieties of common insecticides for bananas are introduced: (1) 5% wettable powder with high efficiency and high efficiency is a new type of insecticide with strong internal absorption with high efficiency and low toxicity. It has significant control effect on crop pests such as aphids and thrips. Its characteristics are: ① ultra-efficient, low dosage, 10g / 667m2, lasting for 20 days, quick effect better than 10% imidacloprid; ② low toxicity, low residue, no drug damage, good control effect of ③ against resistant pests, and no cross resistance with other types of agents. Dosage: 2000-5000 times. (2) Haizheng Chongling is an antibiotic acaricidal insecticide. It has special effect on all kinds of Coleoptera pests, aphids and Lepidoptera root-knot nematodes. The drug is a ten-flash macrolide antibiotic, which is the product of microbial fermentation, the result is complex, the pest is difficult to develop resistance, and has efficient activity against other agricultural pests that have developed drug resistance. The efficacy against pests and mites is 714 days and 30 days respectively. It is safe to people and animals, does not cause cancer, does not cause teratogenicity, and does not cause mutation. The level of residue in crops is very low, and there is no need for safe interval of spraying. Can effectively protect seven-star ladybugs and spiders and other natural enemies. The dosage is 30008000 times. (3) Miman 20% F gel suspension is a kind of insect molting enhancer, which can induce Lepidoptera larvae to produce molting reaction in advance before they enter the molting stage. Stop eating within 6-8 hours after spraying, dehydration within 2-3 days, starvation and death. It is effective for all instar stages of larvae, the dosage is small and the residual period is long, and there are no drug damage problems and residual drug spots on crops, and no adverse effects on beneficial insects, birds and natural enemies. The dosage is 1000-2000 times. (4) Tripterygium is a botanical insecticide extracted from the root of fish rattan, which has contact and stomach toxicity, and has a good effect on aphids and Lepidoptera larvae. Because it is extremely safe for people, animals and crops, it is especially suitable for use in fruits, vegetables, tea and mulberry. Commonly used 2.5% fish rattan essential EC 500-800 times liquid spray. (5) cyanobacteria belongs to a variety of Bacillus thuringiensis. This kind of insecticide bacteria has no toxicity to human, animal, crop and aquatic organisms, and has good stability, so it can be mixed with other pesticides. The bacteria have different degrees of pathogenicity and toxicity to more than 150 species of insects, especially Lepidoptera insects. When pests eat these insecticidal bacteria, they will soon stop feeding, nerve paralysis, insect body softening, decay, stink and death. There are two kinds of wettable powder (10 billion live spores / g) and emulsion (10 billion live spores / ml), which can be applied by spraying, spreading powder, poisonous soil and so on. The commonly used dose is 50 grams of bacterial powder per 667 square meters. If it is mixed with pyrethroids or trichlorfon and other pesticides, it has obvious synergistic effect, but it can not be mixed with fungicides or internal organophosphorus pesticides. The temperature above 30 degrees Celsius has the best effect, and it should be used with caution in sericulture areas. (6) acephate is a low toxic internal inhalation insecticide, which has both stomach toxicity and contact effect, and can kill eggs. It is a slow-acting insecticide with slow initial effect, remarkable effect in 2-3 days and strong after-effect. It is suitable for controlling pests of chewing or piercing mouthparts of many crops, such as agriculture, forestry, fruits, vegetables, etc., and is also suitable for controlling many kinds of harmful mites. Commonly used concentration of 40% acephate EC 500mm 1000 times liquid spray. (7) Lexiben, also known as chlorpyrifos, is a moderately toxic insecticide with contact, stomach toxicity and fumigation. The residual period in leaves is not long, and the residual period in soil is longer, so it has a better control effect on underground pests. Commonly used concentration of 40.7% Lesbon EC 1000-1500 times liquid spray. (8) Wanling, also known as methomyl, is a carbamate insecticide with contact, stomach toxicity, internal inhalation and, more prominently, lethality to some eggs. It has fast efficacy and rapid decomposition on crops, so the residual period is short. It has a good control effect on Plutella xylostella, citrus leaf miner and leafhopper, especially on thrips. Commonly used concentration 24% Wanling EC 600mm 800 times liquid spray. (9) Batan, also known as Paidan and Shamindan, is a derivative of silkworm toxin, which has strong effect, contact, internal suction, antifeedant and egg killing. It has a wide insecticidal spectrum and can be widely used to control food crops, fruits, vegetables and other pests. Because the insecticidal mechanism of Batan is to block the transmission of insect nervous system, which is completely different from that of organophosphorus, organochlorine and carbamate insecticides. Therefore, it is especially suitable for pests that have developed resistance to these kinds of pesticides. Batan has good internal absorption and conduction, so it can also be used as root zone pesticide in addition to spray. Although Batan is moderately toxic, it is highly toxic to silkworms and fish, so it is generally not suitable for use in silkworm and fishing areas. Cruciferous vegetable seedlings such as cabbage and cabbage are sensitive to Batan under high temperature in summer. Commonly used 50% wettable powder 800-1000 times liquid spray. (10) Shachongshuang is a new variety of organic nitrogen pesticides in China in the 1970s, and its action mechanism, scope of application and method of use are basically the same as those of Badan, but it is a domestic pesticide with low price and very popular. It has become the largest tonnage variety in the production of pesticides in China. Commonly used 25% insecticidal double water agent 500 times liquid spray. More insecticide use technology, more banana planting technology
