The main pesticides for controlling fruit tree seedling diseases are: Bordeaux mixture, daisen zinc, thiophanate, carbendazim, retort, lead phosphate, cathin, and rust. These pesticides are called fungicides, and their main role is to inhibit Or kill all kinds of germs. The main pesticides for controlling fruit tree seedling pests are: chlorpyrifos, phoxim, omethoate, chlorfenapyr, ketamine, acesulfame, deltamethrin, and chlorpyrifos. This kind of pesticide is called insecticide, and its main function is to kill pests through different poisoning methods such as stomach poisoning, contact killing, systemic absorption and fumigation. Another pesticide, such as stone sulfur mixture, is both disease prevention and pest control.
The following pesticides cannot be mixed. Bordeaux mixture and stone sulphur mixture cannot be mixed. Because the two pesticides will chemically change after mixing, the formation of copper polysulfide will not only reduce the efficacy, but also cause phytotoxicity. When using these two pesticides in succession, it is also necessary to wait for a certain period of time. First use the stone sulfur mixture, it is necessary to spray the Bordeaux mixture after 20-25 days; first spray the concentrated liquid, it takes 25-30 days to use the stone sulfur mixture.
Bordeaux mixture and stone sulphur mixture and most pesticides, such as phoxim, trithiaphos, phosphazone, dichlorvos, tertiary sterol, ketone, carbaryl, etc. are not mixed, resulting in decomposition of the drug after mixing And failed.
Microbial insecticides, such as Beauveria bassiana and Penicillium, should not be mixed with microbial fungicides such as Jinggangmycin or Chunremycin, otherwise the microorganisms will be killed and the efficacy will be reduced. Oil emulsions, soaps and most insecticides, sterilization can not be mixed, mixed will cause the decomposition or precipitation of the drug to reduce the efficacy.
The combination of organophosphorus pesticides and bromide esters can increase the insecticidal effect, but it can also increase the toxicity to human 6b. Therefore, use it to be safe or avoid using it.
