Potassium dihydrogen phosphate and pesticides used

Generally selected in the crop absorption of phosphorus and potassium nutrients peak period, such as wheat, rice and other cereal crops booting or heading flowering period; rape from the flood season to the flowering period; tuber potato crop expansion period.

Potassium dihydrogen phosphate and some nitrogen fertilizers, micro-fertilizers, and pesticides, etc., can be reasonably matched, and mixed application can save labor, increase fertilizer efficiency and drug efficacy. In the case of mixed crops with poor crop growth, nitrogen deficiency, phosphorus, and potassium, the appropriate concentration of urea is generally required to be 1% to 2%. In boron-deficient soils and in crops where boron fertilizers are effective, such as cotton, canola, and wheat, the use of potassium dihydrogen phosphate and boron fertilisers can increase the yield significantly.

With fungicides (carbendazim, thiram, oxcycline, thiophanate-methyl, etc.), insecticides (Kung Fu, enemies, cypermethrin, rifampin, lespen, etc.), endogenous plant growth regulation Agents (Bi-Ying, Yi-Wei, etc.) are mixed.
