How effective is spraying potassium dihydrogen phosphate on peppers?

Spraying potassium dihydrogen phosphate on peppers promotes flower bud differentiation, increases the fruit-setting rate, promotes fruit cap shedding, improves fruit firmness, and prevents fruit cracking, fruit rot, and fruit drop. It is generally sprayed before flowering, at the young fruit stage, and at the fruit enlargement stage, evenly sprayed on the pepper leaves, covering both the upper and lower surfaces, until droplets begin to fall.

Potassium dihydrogen phosphate is used in agriculture as a high-efficiency phosphorus-potassium compound fertilizer. It is a new type of high-concentration two-element phosphorus-potassium compound fertilizer, containing about 52% phosphorus pentoxide and about 34% dipotassium oxide. It is widely suitable for almost all types of crops, including various economic crops, grains, melons and fruits, and vegetables. It has many excellent effects such as significantly increasing yield and income, improving and optimizing quality, resisting lodging, resisting pests and diseases, and preventing premature aging, and it also helps overcome nutrient deficiency caused by the decline in root absorption capacity due to root aging in the later stages of crop growth.
