The Application and Prospects of Organosilicon in Pesticide Synergism and Environmental Protection

Table of Content [Hide]

In crop management, pesticides pose urgent challenges due to their high cost, high pollution levels, and difficulty in controlling dosage. While pesticides are effective in killing insects, their high cost and environmental impact cannot be ignored. High concentrations of pesticides can cause pesticide damage, while low concentrations may not achieve the desired insecticide efficacy. Therefore, how to reduce pesticide usage while ensuring crop yields has become a pressing issue.

The Application and Advantages of Organosilicon in Pesticides

Organosilicon, by increasing pesticide utilization, has become a common synergist in agricultural production. To address these challenges in pesticide use, researchers are experimenting with adding pesticide synergists to pesticides. These synergists are inactive on their own, but when mixed with pesticides, they can significantly increase pesticide utilization. Organosilicon, as a widely used synergist, has garnered particular attention in current agricultural production.

▲ Mechanism of Action of Synergists

Agricultural organosilicones, also known as synergists or pesticide adjuvants, are primarily composed of ethoxylated polytrisiloxanes. These substances can be widely used in agrochemical sprays, including insecticides, fungicides, herbicides, foliar fertilizers, plant growth regulators, trace elements, and biopesticides. Organosilicones are used in a variety of fields, including insecticides and fungicides, to enhance efficacy and reduce costs.

▲ Requirements and Characteristics of Organosilicon Surfactants

In-depth research into the interactions between adjuvant molecules, pesticide active ingredients, and organisms (such as insects, plant surfaces, and bacteria) provides a solid theoretical foundation for the development of novel, highly effective organosilicon surfactants. Optimizing formulations for different pesticides and crops maximizes the effectiveness of organosilicon surfactants while ensuring their safety for crops. Different pesticides and formulations have different requirements for organosilicon surfactants, but at a minimum, they must meet the following key properties: no degradation of the active ingredient; significant reduction in the formulation's surface tension; stability to water, acid, alkali, salt, and heat; and safety for crops. Therefore, comprehensive formulation optimization is necessary to maximize the effectiveness of silicone surfactants and minimize their adverse effects.

▲ Future Development and Application Potential

The numerous advantages of silicone additives suggest that they have broad market potential in China, particularly in major crop growing areas such as fruit, rice, and vegetables. Due to their high efficiency and environmental friendliness, silicone additives hold broad development prospects in field crop areas, offering enormous potential for disease, insect, and weed control.
