Explain in detail the effect of humic acid products on pesticides.
About the efficiency of humic acid product on pesticides, have been a lot of reports at home and abroad from the early 1960s. The recent reports, most of the content to directly discuss the interaction of humic acid and pesticides, the results can be summarized as follows: Effect of Humic Acid Product on Pesticide 1. Dissolution on pesticides Humic acid has been widely used in many industries at home and abroad. It is reported that the surface tension of the alkali metal salt of peat humic acid and weathered coal humic acid is reported to varying degrees lower than that of water, and the surface tension of the humate on water in water solution can be reduced up to 7-26 kfactor / cm. In contrast, weathered coal humic acid reduces less surface tension of water, but it has large molecular weight and higher hydrophilic group content, which can be regarded as a polymer surfactant that can play a good dispersion and emulsifying effect on pesticides. In the inter...
