Application of herbicide adjuvant
Adjuvants are critical to improving herbicide efficacy, crop safety, reducing herbicide use, reducing environmental pollution and improving economic efficiency. They can be added to the spray solution via a mixing tank to affect various properties such as viscosity, deposit coverage area, physical form, water content, solubility and volatility. In addition, adjuvants reduce the surface tension of the spray solution, thereby improving herbicide retention and wetting ability, while improving diffusion and rain fastness. In addition, they enhance resistance to photodegradation.
The pine olefin additive is a new type of rainproof additive with the environmental characteristics of a bio-based product. Pinene has lipophilic properties similar to oil, a wide range of molecular weights, and a nonlinear molecular structure that increases the retention of reagents on difficult-to-wet plants.
Pine Eye Emulsion is an adjuvant emulsion made from pine oil. When applied one hour before rain, it forms a flexible film on the surface of the crop, thus slowing down the penetration of rainwater into the cuticle. This prevents growers from having to reapply herbicides after rainy days when high concentrations can cause phytotoxicity.
The settling rate of the pine eye emulsion in the performance test was 6.6623 mg/cm2. When used in combination with herbicides during spraying, the pine resin polymer in the emulsion expands the area covered by the herbicide on the ground. Within one hour of application, the emulsion dries and forms a flexible film that encases the chemicals in microcapsules, protecting them from being washed away by rain or other additives.
Pine Eye Emulsion contains a bio-based polymer that is naturally beneficial to crops, flowers and fruits. Its tested contact angle of 44.50° is better than the 55.48° contact angle of its organic-based competitors, making it a superior additive for dispersion purposes due to its better wetting effect.
Loose eye emulsions provide film forming properties by forming an elastic coating on the crop. This coating provides sun protection and anti-transpiration to prevent sunburn on fruits and vegetables.
