Pesticides

Research and Practice of Pesticides

The introduction of colloidal nanotechnology into the field of pesticides can effectively solve the problems related to traditional pesticides. Nanopesticide particles are small in size and have high surface area and volume properties, which help the ingredients to be better distributed on the pest surface. There is also an increasing demand for pesticides in highly dispersed colloidal systems with higher efficiency and lower application doses. For example, the water-dispersed soft colloidal nano-pesticide prepared by the conventional deltamethrin pesticide through the ultrasonic emulsification process can not only obtain high toxicity accuracy at a lower concentration, but also reduce the impact on the environment.

The use of colloidal nanoparticles as active substances in pesticide formulations is also one of the strategies to develop new pesticides. For example, surface-charged hydrophobic silica colloidal particles have been successfully used to control a variety of important agricultural pests.

Alfa Chemistry focuses on developing safer and more efficient new pesticides for agricultural systems. Our extensive expertise in colloidal systems and colloidal particles can be used to improve conventional pesticide formulations and provide promising strategies for the development of novel pesticides. Our vision is to reduce the load of pesticides on the environment.
