Wetting agent: a magical aid to improve the utilization rate of pesticides and fertilizers
In agricultural production, the application of pesticides and fertilizers is a key link in improving crop
yield and quality. However, under traditional application methods, the utilization rate of
pesticides and fertilizers is often not high, and a large amount of nutrients are lost into the soil, which
not only wastes resources but also may pollute the environment. In order to solve this
problem, scientists have developed a magical adjuvant called wetting agent.
1. The basic principle of wetting agent
Wetting agent is a chemical substance that can reduce the surface tension of liquid and make it easier
for liquid to spread on the solid surface. Adding an appropriate amount of wetting agent
to pesticides and fertilizers can significantly improve their wetting properties. When a pesticide or fertilizer
solution containing a wetting agent is sprayed onto plant leaves or soil surfaces, the wetting agent can
quickly reduce the interfacial tension between the liquid and the solid, making it easier for the liquid to
spread and penetrate.
2. The mechanism of action of wetting agents to improve the utilization rate of pesticides
Enhance leaf adhesion:
Wetting agents can increase the adhesion of pesticide solutions to plant leaves and reduce the loss of liquid.
When spraying pesticides, the solution containing wetting agents can fit more
closely to the surface of the leaves, forming a uniform film of medicine. This not only increases the coverage
area of the pesticide, but also prolongs the residence time of the pesticide on the
leaves, thereby enhancing the insecticidal, fungicidal and weed control effects of the pesticide.
Promote the penetration of liquid medicine:
Wetting agents can also promote the penetration of pesticide solutions into the interior of plant leaves.
By reducing the tension on the surface of the leaves, wetting agents make it easier for
the liquid medicine to penetrate the cuticle of the leaves and enter the interior of the leaf tissue. This helps
the pesticide to work faster and improve the control effect.
Reduce the loss of liquid medicine:
During the spraying process, some liquid medicine may be lost due to factors such as wind and rain.
The pesticide solution containing wetting agents can better adhere to the leaves and
reduce the loss of liquid medicine caused by wind and rain. This not only improves the utilization rate
of pesticides, but also reduces pollution to the environment.
3. The mechanism of action of wetting agents to improve the utilization rate of fertilizers
Improve soil wettability:
The dissolution and nutrient release of fertilizers are affected by soil wettability. After adding wetting
agents, the wettability of the soil particle surface is improved, making it easier for
fertilizers to dissolve and disperse in the soil. This helps to quickly release and evenly distribute fertilizer
nutrients and improve the absorption and utilization rate of crops.
Promote nutrient penetration:
Wetting agents can also promote the penetration of fertilizer nutrients into the deep soil layer. By reducing
the interfacial tension between soil particles, wetting agents make it easier for
nutrients to pass through soil pores and reach near the crop roots. This helps the crop roots to better absorb
nutrients and improve the utilization rate of fertilizers.
Reduce nutrient loss:
During irrigation or rainfall, some fertilizer nutrients may be lost with water. Soil containing wetting agents
can better retain water and nutrients and reduce nutrient loss. This not only
improves the utilization rate of fertilizers, but also reduces environmental pollution caused by nutrient loss.
4. Practical application cases and effect evaluation
In actual agricultural production, pesticides and fertilizers with wetting agents have been widely used.
Through comparative experiments, it was found that the use of pesticides and fertilizers
containing wetting agents can significantly increase the yield and quality of crops. At the same time,
wetting agents can also reduce the use of pesticides and fertilizers, reduce production
costs and environmental pollution.
5. Conclusion and Prospect
As a highly efficient adjuvant, wetting agents play an important role in improving the utilization rate
of pesticides and fertilizers. By improving the wetting properties of liquids and promoting
the penetration and distribution of nutrients, wetting agents not only improve the effects of pesticides
and fertilizers, but also reduce resource waste and environmental pollution. In the future
with the continuous advancement of agricultural technology and the continuous optimization of
wetting agent performance, we have reason to believe that wetting agents will play a more
important role in agricultural production.
In summary, wetting agents are one of the effective means to improve the utilization rate of pesticides
and fertilizers. By using wetting agents scientifically and rationally, we can better
promote the growth and development of crops and improve the efficiency and benefits of agricultural production.
