All top five domestic brands have completed molecular reconstruction of side-chain block amino-modified polyethers, replacing traditional linear polyether grafting processes. Conventional products only maintain stable storage for 7~15 days at pH5~8; improved new grades remain unhydrolyzed and unstratified after standing for 60 days in strong acid EC formulations (pH2.2) and alkaline glyphosate aqueous solutions (pH11.5), with surface tension fluctuation ≤0.3mN/m. Meanwhile, microchannel continuous addition processes are matched with ligand-modified Karstedt platinum catalysts, lifting hydrosilylation raw material conversion rate from 87% to 99.2% and lowering by-product low-molecular siloxane content from 5.8% to 0.7%.
Improved polyether EO/PO block ratio reduces the surface tension of new top domestic grades by 8%~12% compared with conventional grades (21~22mN/m). The leaf spreading area of liquid pesticides reaches 181 times that of clean water (national standard 172 times for traditional products), leaf wetting formation time shortened to 2.7s, and adhesion rate on thick-wax peel fruits (citrus, avocado) increased by 41%. Suitable for ultra-low volume drone spraying (5L/ha) with no dry spots or missed spraying, meeting global water-saving dryland plant protection demands.
The problem of calcium-magnesium ion complex precipitation has been solved; the product’s hard water tolerance limit raised from the traditional 550mg/L to 1300mg/L calcium carbonate equivalent. Groundwater with high salinity and alkalinity in the Middle East, Australia and South America can be directly mixed with pesticides without caking or precipitation, eliminating the need for downstream customers to purchase extra water softeners. The tank mixing compatibility range covers all anionic, cationic and nonionic pesticide technical materials, cutting the stratification failure rate of compound formulations from 18% to 1.9%.
Baisenmao and Runhe have taken the lead in mass-producing low-foam special grades. Methyl-capped hydrophobic groups are introduced at molecular end groups; the foam height under high-speed stirring (12000r/min) drops from 128mm to 31mm. No foam overflow loss occurs during automated closed pesticide formulation production; no foam drift during high-altitude drone atomization, lifting liquid pesticide landing utilization rate by 32%.
Optimized siloxane backbone branched chain structure lowers the product freezing point from -10℃ to -22℃. The fluidity remains unchanged during low-temperature pesticide application (0~5℃) in Northern Europe and Canada, solving the industry pain point of nozzle blockage caused by low-temperature precipitation of adjuvants in cold regions.
Dow and Momentive have completed mass production of eco-friendly grades. Traditional trisiloxane only achieves 32% soil biodegradability; improved products can break siloxane-ether bonds under soil microbial action, meeting ECHA 2026 adjuvant biodegradability access standards of the EU and avoiding import restrictions on pesticide adjuvants in Europe. Wacker supports green hydrogenation processes with 95.7% platinum catalyst recovery rate and finished product heavy metal residues＜0.1ppm.
Evonik and Shin-Etsu have launched customized penetration-controlled products with differentiated epidermal spreading and targeted stomatal penetration design. Excessive stomatal infiltration rate of crop leaves reduced by 65%, cutting phytotoxicity incidence on thin-peel crops such as strawberries and grapes from 11.3% to＜2%. The retention period of foliar fertilizer nutrients extends from 7 days to 15 days, reducing topdressing frequency.
Top overseas brands optimize polyether antioxidant side chains; viscosity fluctuation ≤3% under long-term tropical storage (50~55℃), compared with a viscosity increase exceeding 22% for traditional products under the same conditions. Eliminating cooling storage costs for open-air agrochemical warehouses in Southeast Asia and Africa, and ensuring stable product quality during transoceanic sea transportation across equatorial high-temperature routes.
Dow and Wacker have mass-produced 98% active stock solutions (mainstream domestic grades are 100% active, old overseas grades 85%). Under the same dosage for efficacy enhancement, packaging volume is reduced by 13%, the volume of active ingredients loaded per full sea container increased by 15%, and customer warehouse space occupancy cut by 12%.
1. Lower formulation costs: Adjuvant addition dosage reduced from conventional 0.08%~0.12% to 0.045%~0.06%, cutting single-ton pesticide adjuvant procurement costs by 23%~29%. No extra purchase of water softeners and defoaming additives required, slashing comprehensive auxiliary material costs for formulas by over 17%.
2. Expanded global market compliance coverage: Domestic hydrolysis-resistant and biodegradable new grades match new access regulations for pesticide adjuvants in Europe, America, Australia and New Zealand, enabling buyers to develop high-end agrochemical markets simultaneously. Import of overseas eco-friendly grades accelerates local pesticide formulation registration and shortens new product launch cycles by 3~6 months.
3. Reduced storage & transportation loss: Improved high/low temperature stability lowers storage and transportation scrap rate from 7.2% to 1.1%, greatly cutting loss during transcontinental ocean shipping.
1. Pesticide reduction & water conservation for higher yields: Liquid pesticide leaf retention rate lifted by 35%~52%, technical pesticide dosage reduced by 25%~30%, and field pesticide application water consumption cut by up to 70%. Under equivalent pesticide costs, pest and disease control efficacy rises by 28%~38%, with crop yield increased by 8%~14%.
2. Higher tolerance for pesticide application under extreme environments: Direct mixing with hard water, high/low temperature and saline-alkali water sources without pre-treatment. 78% of liquid pesticide residues remain after 48 hours of rain wash, reducing labor and pesticide costs for supplementary spraying after rainfall.
3. Cost reduction for drone spraying: Low-foam and anti-drift properties adapt to ultra-low volume drone spraying, lifting single-flight operation area by 22% and cutting labor costs for large-scale farm plant protection by 31%.
1. Foliar Fertilizer Sector: Penetration-controlled modified products boost medium and trace element fertilizer utilization rate by 42%; the penetration rate of liquid foliar fertilizer formulas in Europe and America rose by 19% year-on-year in 2025.
2. Non-Cultivated Land Herbicides (Orchards / Wasteland): Ultra-low surface tension and alkali-resistant products are compatible with high-concentration glyphosate compound formulations, cutting complaint rates for herbicide tank-mix formulas by 68%.
3. Special Cash Crops (Berries, Citrus): Low-phytotoxicity modified adjuvants have become mainstream raw materials for physical control of citrus red mites worldwide, achieving over 95% mite control efficacy when used alone and reducing chemical acaricide dosage.
