What medicine does scale insect use the most effective?

Scale insects are the general name of insects of the family Homoptera. In order to harm leaves, branches and fruits, males often have wings and can fly. Once emerged, females and larvae live on branches or fruits all their lives, resulting in yellowing of leaves, withering of branches, decline of tree potential, and easy to induce soot disease. let's take a look at what drugs are most effective!

Methotrexate

Methamidophos is an ideal insecticide for killing shell insects and non-internal insecticides. it is used to control pests and mites in fruit trees, cotton, vegetables and other crops, such as sagittal scale, furfural scale, wax scale, brown round scale, pink scale, cotton aphid, cotton red spider, cotton bollworm, alfalfa weevil and so on. Moreover, do not inhale, safe and efficient, and control whiteflies, aphids, kill all beetles, green insects, the disadvantage is that the taste is a little strong.

Thiazine

Thiazide is a new structure of the second generation of nicotine insecticides with high efficiency and low toxicity, which has stomach toxicity, contact and internal absorption activity to pests, and is used for foliar spray and soil root irrigation treatment. After application, it is quickly absorbed and transmitted to all parts of the plant, and has a good control effect on piercing pests such as aphids, planthoppers, leafhoppers, whitefly, etc., and has a special effect on scale insects when combined with methophos.

Silicone penetrating agent

Silicone penetrant has very low surface tension. After adding pesticides in a certain proportion, pesticides can have super-strong expansibility, permeability, dispersion, wettability, efficient internal absorption and conductivity on the plant surface. Especially in the leaf wax layer and other difficult to wetting surface to achieve rapid wetting, dispersion, and infiltrate into plant pores, improve efficacy, rain erosion resistance, so that the effect is long.

Note: methamidophos, thiazide and organosilicon penetrating agents complement each other and are indispensable. When used together, they can kill shell insects. When applying, spray leaves and spray wet soil surface or irrigate roots to kill the eggs in the soil, so that you can kill them. The proportion of the medicine is 11500 times. Take 1 gram of each agent, a total of 3 grams, and then add 1500 grams of water.
