How to Choose the Right Adjuvant for Agricultural Spraying ?
Choosing the right adjuvant is essential to increase spray performance, improve pesticide efficiency, and protect the crop. Selecting the wrong adjuvant can reduce effectiveness and increase cost. Therefore, it is important to understand the purpose of spraying before making a choice.
Understanding the Purpose of Spraying
Before selecting an adjuvant, consider the following factors:
-
Purpose of spraying
-
Type of products being used
-
Quality of water
-
Crop growth stage
All these factors directly influence adjuvant selection.
When to Use Anionic Adjuvants
Anionic adjuvants are suitable when the objective is to remove dust, sticky residues or insect secretions from leaves, or when using contact action insecticides. They clean the leaf surface and improve direct contact between pesticide and pest.
When to Use Non-Ionic Adjuvants
Non-ionic adjuvants are considered safe and effective when spraying fertilizers, micronutrients, biostimulants, fungicides or systemic insecticides. They increase leaf adherence, improve absorption and do not harm the crop.
Hard Water and Tank Mix Situations
If the water is hard or multiple products need to be mixed in the tank, Anionic adjuvants should be avoided. In such cases, Non-ionic adjuvants are the recommended choice.
Sensitive Crops and Frequent Spraying
For crops in fruiting stages, sensitive crops or situations requiring frequent spraying, Non-ionic adjuvants are safer.
Conclusion
In summary, Anionic adjuvants are useful for leaf cleaning and contact pesticides, while Non-ionic adjuvants are best for nutrition, absorption and crop safety. The right adjuvant improves effectiveness, reduces cost and prevents crop damage.
