Adjuvants & Conditioners
“A substance other than water without significant pesticide properties, which enhances or is intended to enhance the effectiveness of an agrochemical, when it is added to that agrochemical”
Why are Adjuvants needed?
Whilst manufacturers of agrochemicals in general formulate their products with adjuvants, there are a number of factors that may compromise the effectiveness of that product:
The inbuilt adjuvant formulation in an agrochemical is designed to be effective at the full label dose of the product. It is common to use reduced doses of products, and the adjuvant loading can be topped up to ensure maximum efficacy of the products used.
The role of adjuvants is to enhance the efficacy of the product being used. Depending on type, adjuvants may increase the products’ activity, increase absorption, improve the spread over the target, increase rain-fastness or alter the physical characteristics of the spray, reducing drift.
Adjuvants act in a number of ways depending upon type; in general they can be grouped as:
Wetters, spreaders, stickers, surfactants, oils, penetrators, water conditioning agents, acidifying agents and buffering agents.
