Advantages and Applications of Agricultural Wetting Agents
As a commonly used pesticide additive in modern times, agricultural wetting agents have many advantages
and have been widely used in agricultural production. The following is a detailed analysis of the advantages
and applications of agricultural wetting agents:
Advantages
Improving pesticide adhesion:
There is usually a waxy layer on the surface of plant leaves, which makes it difficult for pesticide solutions to adhere.
Agricultural wetting agents can reduce the surface tension between the pesticide solution and the surface of plant
leaves, so that the pesticide droplets can be better spread on the surface of the leaves instead of forming water
droplets and rolling down.
Silicone wetting agents have a special molecular structure that can make the droplets fit tightly to the leaves,
ensuring that the active ingredients of the pesticide remain on the leaves to play a role even when the leaves are
tilted or in wind and rain.
Promoting pesticide dispersion:
For solid-dosage pesticides, such as wettable powders, wetting agents can help pesticide particles disperse better in
water and prevent particles from agglomerating.
Lignin sulfonate wetting agents can be adsorbed on the surface of pesticide particles, causing charge repulsion between
particles, so that they are evenly dispersed in water. In this way, during the spraying process, the active ingredients in the
pesticide solution are more evenly distributed, avoiding the situation of excessively high or low local concentrations,
making the control effect more stable.
Enhance the permeability of pesticides:
Some wetting agents can help the active ingredients of pesticides penetrate into the plant epidermis or pests.
Non-ionic wetting agents can interact with the lipid components of the plant epidermis, making it easier for pesticides to pass
through the epidermis and enter the plant tissue. This permeability is particularly important for controlling some pests or pathogens
that parasitize inside plants.
Optimize the performance of pesticide spraying:
Wetting agents can affect the size and distribution of droplets formed by pesticide spraying. Suitable wetting agents can make
droplets smaller and more evenly distributed, increasing the droplet coverage area.
This is crucial when applying pesticides by aircraft or large spray equipment in large-scale agricultural planting. Smaller droplets can cover
crops more comprehensively, improve the utilization rate of pesticides, reduce pesticide waste, and reduce the potential harm to the environment
and crops due to excessive local application of pesticides.
Application
Mixed with pesticides:
When preparing pesticide solution, mixing an appropriate amount of wetting agent with pesticide can improve the wettability and spreadability
of pesticides, so that they can better adhere to the surface of plants.
Improving the effect of pesticides:
By adding wetting agents, the control effect of pesticides can be significantly improved. For example, adding wetting agents to glyphosate can
show a stronger herbicidal effect; adding wetting agents to acetamiprid can effectively enhance the insecticidal effect of pesticides.
Reducing the amount of pesticides:
Since wetting agents can improve the utilization rate and coverage area of pesticides, the amount of pesticides can be appropriately reduced in
actual applications, thereby reducing the cost of pesticides and pollution to the environment.
Adapting to different environments:
Agricultural wetting agents can play a good role in different climates and soil conditions and have strong adaptability.
In summary, agricultural wetting agents have many advantages and have been widely used in agricultural production. Through the rational use of
agricultural wetting agents, we can improve the utilization rate and control effect of pesticides, reduce pesticide costs and environmental pollution,
and inject new impetus into the sustainable development of modern agriculture.
