The rational use of pesticides can improve the control effect, delay the development of insecticide resistance, increase the effectiveness of control, and reduce the amount of pesticides. Mixing pesticides with different pests and diseases can also reduce the number of pesticide applications and thus reduce labor costs.
Pesticide mixing sequence
1 The order of pesticides must be accurately sequenced. The order of mixing of foliar fertilizers and pesticides is usually: micro-fertilizers, water-soluble fertilizers, wettable powders, water dispersible granules, suspending agents, micro-emulsions, water emulsions, water, and emulsifiable concentrates. (In principle, do not mix more than three kinds of pesticides.) Mix well with each other, and then add the next one.
2 Add water first and then add the medicine. When the two dilutions are mixed and mixed, it is recommended to add half a barrel of water to the sprayer and mix the first pesticide after mixing. Then, dilute the remaining pesticide in a plastic bottle, dilute it, pour it into the sprayer, mix it, and so on (if you want to be effective, don't be lazy).
3 Regardless of the mix of agents, it should be noted that “the current distribution should not be used for a long timeâ€. Although the drug solution does not respond at the time of the dispensing, it does not mean that it can be stored for a long time. Otherwise, it will easily produce a slow reaction and gradually reduce the efficacy of the drug.
Pesticide Mixing Principle
â— The combination of different pesticides with different pesticide-killing mechanisms can increase the effectiveness of control and delay the development of insecticide resistance.
â— The pesticides with different poisoning effects include contact, stomach poisoning, fumigation and internal absorption. The fungicides have the functions of protection, treatment and internal absorption. If these agents with different prevention and control effects are mixed, they can be used together. Complementing each other will produce good control effects.
â— Insecticides used in different insect states can be mixed and used as insecticides in different insect states to kill various insect pests in the field and kill them completely.
â— Different types of pesticides with different time-use pesticides have a good effect of quick-effect control, but the effective period is short; some quick-effect control effects are bad, but they take a long time. Mixing such pesticides not only has good control effect after application of pesticides, but also has the effect of long-term control.
â— Although synergistic agents used with synergists have no direct poisoning effect on pests and diseases, the use of pesticides in combination with pesticides can increase control effectiveness.
â— When pesticides that act on different pests and diseases are mixed at the same time when several pests and diseases occur, using this method can reduce the number of spraying and reduce the working time, thereby improving the efficacy.
Precautions for Pesticide Mixing
Although there are many advantages in using pesticides, they should not be mixed randomly. Unreasonable mixing is not only useless, but also has the opposite effect. Mixed pesticides should pay attention to the following points.
â— Does not change the physical properties
That is, no oil, flocculation, sedimentation, or discoloration can occur after mixing, and no phenomenon such as heat generation or bubble generation can occur. If the same powder, or the same as granules, fumigants, aerosols, can generally be mixed;
Between different dosage forms, such as wettable powders, emulsifiable concentrates, emulsions, suspensions, and water solvents, liquids that use water as the medium should not be used arbitrarily.
â— Does not cause chemical changes
1 Including many pharmaceutical agents that cannot be mixed with alkaline or acidic pesticides. Carbamates, pyrethroid insecticides, thiram, dioscin, and other dithioamides under alkaline conditions such as Bordeaux mixture, lime sulfur, etc. Formic acid bactericides are prone to hydrolysis or complex chemical changes, thereby destroying the original structure.
2 Under acidic conditions, 2,4-D sodium salt, 2A 4 sodium chloride salt, amitraz, etc. will also decompose, thus reducing the efficacy.
3 In addition to acidity and alkalinity, many pesticides cannot be mixed with drugs containing metal ions.
4 Dithiocarbamate fungicides, 2,4-D herbicides and copper preparations can produce copper salts to reduce the efficacy.
5 Thiophanate-methyl and thiophanate-methyl can be complexed with copper ions and lose their activity.
6 Remove copper preparations, other preparations containing heavy metal ions such as iron, zinc, manganese, nickel and other preparations, be careful when mixing.
7 Lithosulphide mixed with Bordeaux mixture can produce harmful copper sulfide and also increase soluble copper ion content.
8 Propene, butachlor, etc. cannot be mixed with organic phosphorus and carbamate insecticides. Some chemical changes may cause phytotoxicity.
â— Cross-resistance pesticides should not be mixed
For example, the bactericide carbendazim and thiophanate-methyl have cross-resistance. Mixing can not only delay the growth of the bacteria, but also accelerate the development of drug resistance.
â— Biopesticides cannot be mixed with fungicides
Many pesticide bactericides have a lethal effect on biological pesticides. Therefore, microbial pesticides and bactericides must not be mixed.
