Can potassium phosphite be mixed with trace elements (taboos for compound use of potassium phosphite)

Potassium phosphite is a high-quality phosphorus and potassium high-efficiency fertilizer. Its main function is to quickly supplement phosphorus and potassium fertilizers for crops, and it is easily absorbed by crops.

Moreover, it has a high absorption and utilization rate, promotes plant rooting, promotes fruit color change, increases sugar content, promotes flower bud differentiation, has antibacterial and antifungal effects, rapidly expands, and protects fruits and controls shoots.

Potassium phosphite is used together with trace elements

We have done a lot of experiments and found that potassium phosphite and trace elements can be mixed and used without any problems, but it is recommended to mix them before use .

In addition to supplementing phosphorus and potassium fertilizers, potassium phosphite also has a bactericidal effect. Since the phosphorus fertilizer in potassium phosphite is trivalent phosphorus, when it is converted into pentavalent phosphorus fertilizer that can be absorbed by plants, it has a bactericidal effect and is very effective in inhibiting diseases .

Let's learn about potassium phosphite. Potassium phosphite is mainly used to supplement phosphorus fertilizer and potassium fertilizer. However, the content of potassium phosphite produced by each manufacturer is different.

The country has no standards for potassium phosphite, a new type of fertilizer, but in order to circulate the fertilizer in the market, many manufacturers will add a certain amount of nitrogen fertilizer to potassium phosphite to make it meet the standards for macroelements.

Although potassium phosphite contains high contents of both phosphorus fertilizer and potassium fertilizer, the conversion rate of phosphorus fertilizer is relatively slow and low . Therefore, it is recommended to supplement phosphorus fertilizer with potassium dihydrogen phosphate, which has better water solubility.

There are many trace elements, such as iron fertilizer, zinc fertilizer, boron fertilizer, manganese fertilizer, and molybdenum fertilizer . The most commonly used ones are iron fertilizer, zinc fertilizer, and boron fertilizer. Most iron fertilizers are ferrous sulfate, and most zinc fertilizers are zinc sulfate. There is no problem in mixing them.

However, when mixing boron fertilizers, everyone must pay attention to the pH value of the boron fertilizer. Most of them are alkaline, so you must pay attention to the pH problem .

Although potassium phosphite can be mixed with a variety of fertilizers and drugs, including trace elements, the dosage of potassium phosphite is relatively strict, and excessive use will cause pesticide damage.

Potassium phosphite and trace elements both have the function of controlling growth. It is recommended to add 20 ml of potassium phosphite to a 30-jin bucket of water when mixing them .

Precautions for use of potassium phosphite mixture

Potassium phosphite is a new multi-purpose special phosphorus and potassium fertilizer that can prevent diseases and inhibit bacteria, loosen the soil, promote root growth and plant growth, and promote flowering and fruit expansion. However, you should pay attention to the following when using it in combination:

(1) Potassium phosphite cannot be mixed with alkaline or strongly alkaline pesticides such as Bordeaux mixture, lime sulfur, rosin mixture, sodium pentachlorophenol, wood ash, lime, amines, etc., as it will cause floccules and precipitation, affecting the efficacy of the pesticide.

(2) Potassium phosphite has good miscibility and can be used in combination with copper preparations without causing precipitation or phytotoxicity.

(3) Potassium phosphite can accelerate the maturation of new shoots. It will not cause phytotoxicity to young fruits if it is used in the spring shoot stage and young fruits. Potassium phosphite is effective in preventing cankers. It is effective when used alone. If the canker outbreak is severe, it is recommended to use it together with copper preparations.
