Potassium dihydrogen phosphate is effective, but try not to use it with these pesticides.

As a highly efficient binary compound fertilizer, potassium dihydrogen phosphate provides plants with two major elements of phosphorus and potassium, which has a wide range of uses and strong adaptability. it can be widely used not only in crops, but also in horticultural vegetable and flower planting. a variety of application methods can choose not only ditch fertilization but also foliar spraying, which is welcomed by the majority of farmers and horticultural flower growers.

In order to save effort in agricultural production, potassium dihydrogen phosphate is often mixed with pesticides and foliar spraying, but not all pesticides can be mixed with potassium dihydrogen phosphate. First of all, we should know the chemical properties of potassium dihydrogen phosphate.

Due to the hydrolysis of a large number of H ions, the solution of potassium dihydrogen phosphate is also acidic. In addition, the chemical properties of the hydrolyzed phosphate are unstable and combine with most metal ions to form flocculent precipitation or insoluble matter. Therefore, based on these two points, all those that contradict the above two points are not recommended to be mixed with potassium dihydrogen phosphate.

For alkaline pesticides, the efficacy is reduced due to the neutralization reaction with potassium dihydrogen phosphate, so mixed application of the two is not recommended. However, for most pesticides, they are neutral or acidic, and can be used with potassium dihydrogen phosphate. You can carefully check the pH value of pesticides when applying pesticides.

Secondly, some inorganic copper insecticides and fungicides can not be applied together with potassium dihydrogen phosphate, such as Bordeaux solution mixed with potassium dihydrogen phosphate will form precipitates, thus reducing the effect of pesticides and unable to supplement phosphorus for crops.

It is worth noting that the governor regulators on the market can basically be mixed, but even so, we should try to check the instructions and apply selectively according to the instructions.

In addition, there are some pesticides will be clearly marked, it is clear that can not be mixed with potassium dihydrogen phosphate, so it is important to read the instructions carefully before use. In addition, for some fertilizer effect agents of micro-fertilizer, try not to mix them together to avoid reducing the fertilizer efficiency because of the reaction between phosphate and mineral ions.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
