For the mixture of foliar fertilizer and pesticide, we should pay attention to the following points, otherwise it will be wasted.

How to mix foliar fertilizer and pesticide? In fact, according to the actual detailed introduction of therapeutic drugs, we should read the instructions carefully before mixing drugs (for example, foliar fertilizers containing carbohydrates cannot be mixed with inorganic copper, traditional Chinese medicine, copper hydroxide, etc.); in fact, due to the different characteristics of various chemical fertilizers and pesticides, if the mixture does not harm the actual effect of taking fertilizer and medicine and even cause fertilizer damage. The following are common problems in mixing foliar fertilizers and pesticides.

First, it is necessary to ensure the stable appearance of foliar fertilizer and pesticides after mixing.

This is because foliar fertilizer will have organic chemical or physical reactions with pesticides, which will endanger the effectiveness of pesticides or lead to drug damage. If the main performance of the solution is poor, it is not suitable for mixed application. After mixing, even if the physical properties of the solution are good, we should first carry out small-scale experiments to see if it is very easy to find fat and drug damage, and then apply it on a large scale.

Second, attention should be paid to the order of mixed use of foliar fertilizer and pesticides.

Generally speaking, a single-dose solution is selected with a certain amount of water, and then another single-dose diluent is used; it is not possible to first mix two kinds of single-agent, and then tap water diluent, so as to prevent side effects, resulting in the destruction of components and the deterioration of physical properties. When foliar fertilizer is mixed, the mixing order of foliar fertilizer and pesticide is generally as follows: foliar fertilizer, wettable powder, suspending agent, powder and EC are added successively, each one is fully mixed and stirred, and then the next one is added.

Third, pay attention to the application of "water" when mixing

Water does great harm to the medicine solution, and the ph pH and ion concentration of water are all harmful to the actual effect. For tap water, it is better to use neutral water with low ion concentration, such as clean precipitation, rivers and so on.

Fourth, pay attention to match it with current use

Although the liquid has no side effects when it is first mixed, it is very easy to cause slow reaction after putting it for a long time, resulting in lack of power or easy to cause drug damage. If some kinds of pesticides are stable under the weak alkaline standard, but also pay attention to the current use, if placed for a long time, it is also easy to be ineffective.

Several taboos in the application of the mixture of foliar fertilizer and pesticide

1. Partial alkali pesticides should not be mixed with organic fertilizers such as ammonium nitrogen fertilizer and phosphate fertilizer, otherwise ammonia evaporation will be damaged and fertility will be reduced.

2. Pesticides containing arsenic should not be mixed with potassium salts and acetate organic fertilizers, otherwise they will cause drug damage due to soluble arsenic.

3. Partial alkali fertilizers such as sodium hydroxide, lime powder and grass ash should not be mixed with pesticides such as insecticides, otherwise the drug power will be reduced.

4. Chemical pesticides should not be mixed with microbial pesticides.

Because chemical pesticides have volatiles and corrosion, when mixed with microbial pesticides such as Streptococcus borer, cyanobacteria and so on, it is easy to kill microbial bacteria and reduce the control effect.

Above are the common problems and application taboos of the mixture of foliar fertilizer and pesticides. It is expected that farmers should pay attention to many key points in the case of spraying, otherwise they will not only have no medicine, but also continue to have other problems, which will be lost because of the small and the big.
