What pesticides are commonly used to control insects when growing bananas? Please introduce the use and effect of various pesticides. The following pesticides are generally used for pest control in banana cultivation (see below): ⑴ 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. It is extremely safe for people, animals and crops, and is especially suitable for use in fruits, vegetables, tea and mulberry. 2.5% fish gum essential oil is often sprayed with 500% 800 times liquid. ⑵ cyanobacteria belongs to a variety of Bacillus thuringiensis. This kind of insecticidal bacteria is non-toxic to human, animal, crop and aquatic crops, has good stability and 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 the pests eat these insecticidal bacteria, they will soon stop feeding, nerve paralysis, insect body softening, decay, stink and death. There are 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 per mu of bacterial powder. If mixed with pyrethroids or trichlorfon and other pesticides, it has obvious synergistic effect. However, it should not be mixed with fungicides or organophosphorus insecticides. The effect of application above 30 ℃ is the best, and it should be used with caution in sericulture areas. ⑶ acephate is a low toxic internal inhalation insecticide, which has both stomach poison and contact effect, and can kill eggs. It is a slow-acting insecticide with a slow initial effect for 2-3 days and a strong aftereffect. it is suitable for controlling the pests of chewing mouthparts or piercing mouthparts of many crops, such as agriculture, forestry, fruits, vegetables and so on. It is suitable for the control of many kinds of harmful mites. Commonly used concentration of 40% acephate EC 500mm 1000 times liquid spray. ⑷, also known as chlorpyrifos, is a moderately toxic insecticide with contact, stomach toxicity and fumigation. The residual period in leaves is not long, but the residual period in soil is longer, which has a better control effect on underground pests. Commonly used concentration of 40.7% Lesbon EC 1000-1500 times liquid spray. ⑸ Wanling, also known as methomyl, is a carbamate insecticide, with contact, stomach toxicity, internal inhalation, more prominent is to kill some eggs. It has fast efficacy, rapid decomposition on crops and short residual period. It has a good control effect on diamondback moth, citrus leaf miner and leafhopper, and has a special effect on thrips. Commonly used concentration 24% Wanling EC 600mm 800 times liquid spray. ⑹ Badan, also known as Paidan and Shamindan, is a derivative of Bombyx mori toxin, which has strong stomach toxicity, contact, internal inhalation, antifeedant and egg-killing effect. 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 the action mechanism of organophosphorus, organochlorine and carbamate insecticides, it is especially suitable for pest control which has developed resistance to these species. Batan has a good effect of internal absorption and conduction, in addition to spray, it can also be used as root zone pesticide. Although Batan is moderately toxic, it is highly toxic to silkworms and fish, so it is generally not suitable for use in silkworm and fish 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. ⑺ Shachongshuang is a new variety of organic nitrogen pesticides in China in the 1970s. The action mechanism, scope of application and method of use are basically the same as those of Batan, but because they are domestic pesticides, they are cheap and sell very well, so they have become the largest tonnage variety in pesticide production in China. Commonly used 25% insecticidal double water agent 500 times liquid spray.
