The compound taboo of taking advantage of enemy stability

Nadimel is a low toxic internal absorption fungicide, which is composed of a new methoxyacrylate fungicide oxime and endotriazole fungicide tebuconazole, which has both protective and therapeutic effects. The product has high bactericidal activity, strong internal absorption and long effective period. it is used to control major fungal diseases in many crops, and has obvious control effect on cucumber, tomato, Chinese cabbage and rice.

Diazepam can be mixed with general pesticides, but not with strongly alkaline pesticides, nor with too many types of pesticides.

Pesticide compounding should follow the following principles:

1. Chemical changes in the effective components of pesticides should not be allowed when mixed with pesticides. First, the pesticides that cause drug damage to crops due to chemical reactions after mixing can not be mixed: for example, Bordeaux liquid and stone sulfur mixture can not be mixed. Stone sulfur mixture can not be mixed with turpentine mixture, organic mercury pesticides, heavy metal pesticides and so on. Second, acid-base pesticides can not be mixed: commonly used pesticides are generally divided into acidic, alkaline and neutral three categories, acid-base pesticides can not be mixed. Third, pesticides with esters, amides and other structures should not be mixed with alkaline pesticides to avoid hydrolysis of lipids or amides. Fourth, some sulfur-containing fungicides such as zinc and thiram should not be mixed with insecticides trichlorfon and monocrotophos. Fifth, some ionic pesticides, especially herbicides such as paraquat, 2-methyl-4-chloramine salt and glyphosate, can also react and reduce the efficacy when mixed.

2. The pharmacological properties of the agent should not be destroyed. The mixture of the two kinds of EC is still required to have good emulsification, dispersibility and wettability. The mixed use of two kinds of wettable powder requires good suspension rate, wettability and spreading performance. This is not only a condition to exert its efficacy, but also to prevent failure, reduction of efficacy or drug damage due to changes in physical properties.

3. It is necessary to ensure that side effects such as drug damage do not occur after mixed use. For example, organophosphorus pesticides should not be mixed with paspalum, which can cause drug damage to crops.

4. The safety after mixed use should be ensured. After the mixed use of pesticides, it is necessary to ensure that the toxins are not increased and are absolutely safe for human beings and animals.

5. The mixing of pesticides should be reasonable. First, the collocation between varieties should be reasonable. If the weeds of Gramineae in soybean field are controlled, the weeds can be controlled by catching and covering grass alone. If the two are mixed, although it is feasible in terms of drug stability, it can not increase the efficiency. Second, the cost should be reasonable. The cost of mixing is generally lower than that of single use. For example, the more expensive new internal absorption fungicides are mixed with cheaper protective fungicides, and the more expensive pyrethroids pesticides are mixed with organophosphorus pesticides.

6. It is necessary to make clear the scope of application of mixed medicament. It is necessary to make it clear that there is not only a relationship but also a difference between the single application range of various effective ingredients after pesticide mixing. Read the instructions carefully before mixing pesticides, and do the miscibility test before mixing. The mixed use of pesticides requires different modes of action and treatment of different control objects, in order to expand the control scope and enhance the control effect after the mixed use of pesticides. After the use of the mixture, the pesticide residues of agricultural and sideline products should be lower than that of single agents. Mixed pesticides are meaningful only if they have their own characteristics in the scope of use and effect.
