Organic silicon is currently one of the most widely used synergistic agents in agricultural production. When mixed with appropriate pesticides, it can significantly improve pesticide utilization.
01 Organosilicone differs from other common pesticide synergists or activators:
★ Organosilicone has lower surface expansion force, stronger diffusion, spreadability, adhesion, penetration, wetting, temperature resistance, and rain erosion resistance.
★ It can be used in combination with the vast majority of fungicides, insecticides, herbicides, plant growth regulators, and foliar fertilizers on the market, significantly improving the effectiveness of various pesticide solutions.
★ Organosilicone has a superior spreading function, resulting in a wider and more uniform coverage area for the pesticide solution, allowing for greater absorption or penetration of the solution on leaves and insect bodies, leading to more significant control effects.
★ Organosilicone can reduce the frequency of pesticide application and pesticide costs, saving up to 30% or more on pesticides and 50% or more on water consumption.
For example, when spraying pesticides with organosilicon, just a few drops on the leaf are enough for the solution to spread and cover the entire leaf; this effect is not achieved with pesticides diluted directly with water.
02 What are the characteristics of adding organosilicon to pesticide spraying?
1. Superior spreading ability, making it easier for the solution to wet the target pesticide. The spreading ability of the pesticide solution on the surface of plant leaves or pests directly affects the efficacy.
Most plant leaves and pests have a cuticle, wax layer, hairs, or rough surfaces that do not easily adhere to pesticides. Pesticides diluted directly with water are very unstable on these surfaces.
Adding organosilicon effectively solves these problems, thus maximizing the efficacy of the pesticide.
2. Smaller contact angle, significantly improving the spreading ability of the pesticide solution on the target. The smaller the contact angle between the pesticide solution and the leaf or pest surface, the better the spreading and distribution of the solution, and the better the pesticide effect.
Organosilicon, due to its very low surface tension, significantly reduces the contact angle of pesticide sprayed onto plant leaves and insect surfaces, thus achieving better pesticide application.
3. Strong spreadability, greatly increasing the coverage area of the pesticide solution on the target object. Pesticide solutions with added organosilicon can multiply the coverage area on crop leaves, which is a key reason why using organosilicon adjuvants can significantly improve pest and disease control.
4. Strong penetration, absorption, and rain washout resistance, greatly improving the stability of the pesticide solution. Organosilicon allows pesticides sprayed onto plant leaves and insect surfaces to penetrate the target object through stomata faster, better, and in greater quantities.
It also has excellent rain washout resistance.
This effect extends to foliar fertilizers, where organosilicon is added, resulting in a significantly improved effect that cannot be achieved by using pesticides or foliar fertilizers alone.
03 Precautions Several points should be noted when using organosilicon.
I. Prepare and use immediately; use the prepared pesticide solution as soon as possible.
II. Reduce the amount of water used for spraying and appropriately increase the spraying speed. The spray volume should be enough to form a water film but not water droplets.
III. During spraying, wear protective equipment as required for the pesticide application, paying particular attention to eye protection.
IV. For pesticides prone to causing phytotoxicity, such as flusilazole, flutriafol, fluazinam, propargite, and fenbutatin, the addition of organosilicon is not recommended.
V. Application is best done before 10:00 AM or after 4:00 PM, avoiding application in high temperatures. Strictly adhere to a dilution ratio of 3000 times or higher.
Organosilicon enhances spreadability, is a good adjuvant for synergistic effects, and improves pesticide stability.
