Selection and Use of Antifoaming Agents in Agriculture

Agricultural defoamers include those used in herbicides, insecticides, and fungicides.  These are generally complex organic compounds. To ensure even distribution on crops, surfactants are added to formulate wettable powders or oil-in-water emulsions. Therefore, significant foaming occurs during dilution and application. This foaming reduces the uniformity of the pesticide dispersion, affects efficacy, and interferes with spraying operations.

Herbicide Defoamer E-385/386

This herbicide defoamer is made from modified polyether and fluorine-based raw materials, and is particularly suitable for maintaining defoaming and foam suppression under high temperature, strong acid/alkali, high shear force, and high pressure conditions. It has excellent high-temperature resistance, acid and alkali resistance, does not float, and does not separate oil. It is used in the production or application of herbicides.

Fertilizer Defoamer E-385/386

This fertilizer defoamer is made from silicone polyether combined with various active additives through a special process. It is easily dispersed in aqueous systems, has strong self-emulsifying properties, good defoaming, and long-lasting foam suppression. It is used in liquid fertilizer production, fertilizer manufacturing, phosphate fertilizer industry, seed fermentation, and other applications requiring defoaming.

Pesticide Defoamer E-387/388/389
This pesticide defoamer is made from silicone polyether combined with various active additives through a special process. It is easily dispersed in aqueous systems, has strong self-emulsifying properties, good defoaming, and long-lasting foam suppression. It is used for defoaming during pesticide production and for preventing foaming during spraying operations.
Zhonglianbang's agricultural defoamers can be directly added to the foaming system.  They must be stirred evenly before use. The recommended dosage is 0.05% to 0.3% of the total volume; the final dosage should be determined based on actual experimental conditions.
