Agricultural silicone adjuvant
Agricultural silicone adjuvant is a type of tank-mix additive used to enhance the performance of pesticides, herbicides, and foliar fertilizers. Unlike conventional surfactants, silicone-based adjuvants are highly effective at reducing surface tension, improving wetting, spreading, and penetration of agrochemicals on plant surfaces.
Agrochemical Tank-Mix adjuvants are auxiliary substances typically mixed with pesticides or fertilizers in the spray tank just before application. While they lack biological activity themselves, they can greatly improve pesticide performance when used in combination with agrochemicals.
Based on their composition, pesticide synergists can be classified into:
-
Surfactant-based adjuvants
-
Silicone-based adjuvants
-
Vegetable oil-based adjuvants
-
Mineral oil-based adjuvants
-
Inorganic salt-based adjuvants
-
Other types of adjuvants
Improving Agochemicals Dispersion and Stability
Agrochemicals must be uniformly dispersed in water or other solvents to ensure application. Adjuvants containing surfactants reduce the surface tension of pesticide solutions, facilitating better dispersion and improving stability.
Enhancing Agrochemicals Penetration
Many agrochemicals need to penetrate plant cuticles or insect integuments to be effective. Adjuvants can break down waxy layers on leaves or insect exoskeletons, allowing agrochemicals to reach their target more efficiently.
Some silicone-based penetrants enable rapid pesticide absorption into plant tissues, significantly improving pest control efficacy.
Increasing Agrochemicals Adhesion
To minimize bounce-off and runoff, agrochemicals must adhere firmly to plant surface after spraying. Adjuvants enhance droplet retention, reduce drift, and prolong residual activity, prevent agrochemicals wash-off by rain and improving utilization efficiency.
Enhancing Compatibility and Absorption in Tank-Mixes
In aerial spraying, agrochemicals are often mixed with fertilizers. However, complex interactions (e.g., particle aggregation, ionic reactions, pH changes) can cause stratification, flocculation, or precipitation. Adjuvants also reduce particle size, enhancing absorption and translocation, make them more bioavailable and improving fertilizer efficiency.
Agricultural adjuvants play a vital role in modern farming. Proper selection and use of these additives can enhance agrochemicals efficiency, reduce production costs,improve crop protection efficiency, and contribute to sustainable agriculture.
