Potassium dihydrogen phosphate is a phosphorus potassium compound fertilizer, which is a high concentration, high-quality, chlorine free potassium fertilizer. It contains both phosphorus and potassium as key elements. Phosphorus has the ability to take root, promote flower bud differentiation, and provide energy for fruit enlargement. Potassium in the later stage of growth can improve photosynthesis, promote nitrogen absorption, make crops mature early, increase fruit sugar and water content, and enhance disease and drought resistance. It can maximize the yield and quality of fruits. Can potassium dihydrogen phosphate be mixed with pesticides?
1. Potassium dihydrogen phosphate can be mixed with fungicides and insecticides, but before mixing, it is necessary to understand the acidity and alkalinity of the mixed agent.
2. Potassium dihydrogen phosphate is weakly acidic with a pH value of around 6.6-6.7, so it cannot be mixed with alkaline agents such as copper preparations, potassium permanganate, and manganese zinc.
3. When potassium dihydrogen phosphate is mixed with insecticides, pyrethroid pesticides can be chosen, while organic phosphorus pesticides are not recommended to be mixed with them.
4. Potassium dihydrogen phosphate is generally used as foliar spray to supplement crops with high phosphorus and potassium fertilizers. This agent can be mixed with urea to supplement crops with three elements of nitrogen, phosphorus, and potassium.
5. When mixing fungicides containing metal ions with potassium dihydrogen phosphate, a small amount of mixing test is required first to see if there will be problems such as coagulation. If there is no coagulation during the experiment, it can be prepared and used on site.
