Agricultural spray adjuvants Introduction An agricultural adjuvant is broadly defined as any substance added to the spray tank, separate from the pesticide formulation, which will improve the performance of the pesticide being sprayed. These adjuvants perform a variety of tasks, but their contribution to raising crop production performance can be summarized as helping to optimize the efficacy levels of agricultural chemicals. Different tasks require different adjuvants- once the circumstances requiring an adjuvant have been assessed, the most appropriate adjuvant can be selected.
There is a clear technical justification for using adjuvants when:
• The pesticide label specifies the need;
• You can clearly identify specific problems that will reduce pesticide efficacy;
• There is reliable data showing an economic benefit;
