The application of wetting agents is also of great significance in agricultural production. Firstly, in the process of pesticide spraying, wetting agents can enhance the adhesion ability of the pesticide solution on the surface of plant leaves, reduce the loss of the solution, and improve the utilization rate and control effect of pesticides. Secondly, adding an appropriate amount of wetting agent in the irrigation system can improve soil moisture distribution and promote the absorption of water by crop roots, especially in arid areas. This effect is particularly significant and helps to improve crop drought resistance and yield.

In addition, wetting agents are widely used in seed treatment to improve the surface wettability of seeds, promote water absorption and germination, and increase germination rate and seedling uniformity. Meanwhile, in some agricultural fertilizers, wetting agents can also help fertilizer particles better disperse in the soil, accelerating nutrient release and crop absorption.
