Can a silicone adjuvant improve the adhesion of pesticides to plant surfaces?

How Silicone Adjuvants Revolutionize Pesticide Adhesion and Crop Protection

The Science Behind Enhanced Adhesion

Silicone adjuvants represent a breakthrough in agricultural technology, specifically engineered to overcome the fundamental challenge of pesticide adhesion to plant surfaces. These advanced surfactants possess unique molecular properties that dramatically reduce surface tension in spray solutions, enabling them to spread up to 10 times more effectively than conventional adjuvants.

The key mechanism lies in their ability to lower surface tension to below 22 dynes/cm, forming an ultra-thin spreading layer on plant leaves and pest surfaces. This reduces the contact angle to less than one-third of traditional adjuvants, ensuring spray droplets spread evenly over even the most hydrophobic surfaces like waxy or hairy leaves.

Market Analysis and Industry Growth

The global silicone additives market demonstrates robust growth, driven by increasing demand across agricultural applications. The market was valued at USD 1.87 million in 2023 and is projected to reach USD 5.52 million by 2032, with a compound annual growth rate (CAGR) of 6.00% during the forecast period.

Asia-Pacific dominates the market, accounting for the largest share due to rapid industrialization and expanding agricultural activities. The region’s strong growth is supported by increasing construction, automotive, and electronics industries that utilize silicone additives in various applications.

Key Performance Benefits

Enhanced Pesticide Efficacy

Silicone adjuvants significantly improve the biological activity of herbicides, fungicides, and insecticides. Research shows they can increase pesticide utilization rates by 30-50%, reducing chemical loss and minimizing environmental impact. In field trials, adding just 0.05% silicone adjuvant to dimethoate emulsifiable concentrate achieved the same insecticidal effect while reducing water consumption by 67%.

Superior Rainfastness and Durability

These adjuvants enhance deep penetration of active ingredients into plant tissues, protecting agrochemicals from being washed away by rain or irrigation. This rainfastness extends the effectiveness of pest and disease control, reducing the need for frequent reapplications and lowering overall chemical usage.

Water Conservation and Efficiency

Silicone adjuvants work effectively at low water volumes, allowing farmers to reduce spray volumes from 40-50 kg per mu to 15-20 kg, and even further to 5-10 kg with low-volume spray technology. This water-saving effect is particularly significant in fruit tree planting and arid regions.

Industry Standards and Certifications

Leading manufacturers like Biyuan adhere to stringent quality standards, including ISO 9001 for quality management systems and ISO 14001 for environmental management. Many products also hold certifications for automotive standard IATF 16949, EFfCI GMP for cosmetics, and FSSC 22000 for food applications.

Biyuan’s production facilities maintain compliance with REACH, ROHS, and PAHS regulations, ensuring products meet international safety and environmental standards. The company also holds certifications for halal and kosher dietary standards, expanding market accessibility.

Application Scenarios and Target Industries

Herbicide Applications

Silicone adjuvants are particularly effective in enhancing the efficacy of glyphosate and other post-emergence herbicides. They facilitate better coverage of weed surfaces, especially those with waxy or hairy leaves that typically resist water-based solutions.

Fungicide and Insecticide Sprays

These adjuvants increase adhesion and penetration of protective chemicals, improving control of diseases and pests. Their ability to penetrate through both stomatal and cuticular pathways ensures faster absorption into plant tissues.

Foliar Fertilizers

Silicone adjuvants enhance nutrient absorption through leaves by improving droplet retention, spreading coverage, and penetration through the waxy cuticle layer. This increases the utilization rate of nitrogen fertilizer by 20-25% and phosphorus fertilizer by 15-20%.

Precision Agriculture

These adjuvants are increasingly used in drone spraying and precision agriculture systems, providing uniform distribution and reducing chemical drift. Their compatibility with ultra-low-volume (ULV) spraying systems makes them ideal for modern high-efficiency farming practices.

Customer Pain Points and Solutions

Challenge: Poor Pesticide Adhesion

Many farmers struggle with pesticide runoff and poor coverage on waxy leaf surfaces, leading to reduced efficacy and increased chemical costs. Biyuan’s silicone adjuvants solve this by reducing surface tension and improving droplet retention, ensuring maximum coverage even on difficult-to-wet surfaces.
