Agricultural spray adjuvants do not reduce the amount of pesticide needed below the recommended use rate on a pesticide label. In fact, it is illegal to use a pesticide in the US outside of the instructions on the label, although FIFRA , the US law governing pesticide use, does allow for the use of pesticides at rates below the label, as long ...
The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI - also called the active substance). Pesticide products very rarely consist of the pure active ingredient.

Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
Adjuvants are chemicals added to enhance the performance or efficacy and/or alter the physical properties of the pesticidal agents. [19] More than 200 EPA registered pesticides recommends specific addition of one or more adjuvants into the pesticidal mixture to improve overall efficacy. [ 19 ]
As agricultural spray adjuvants, surfactants may be pre-mixed into commercial formulations or they may be purchased separately and mixed on-site. [134] Polyethoxylated tallow amine (POEA) is a surfactant used in the original Roundup formulation and was commonly used in 2015. [135] The percentage of POEA varies.
It is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate, and glufosinate herbicides.
Crop oil or crop oil concentrates are petroleum-based additives that are used as adjuvants to increase the efficacy of pesticides in agricultural applications. [1] Crop oils are composed primarily of paraffin or naphtha-based petroleum oil and crop oil concentrates are composed of emulsifiable petroleum-based oil.
Restricted use pesticides (RUP) are pesticides not available to the general public in the United States.Fulfilling its pesticide regulation responsibilities, the United States Environmental Protection Agency (EPA) registers all pesticides as either "unclassified" or "restricted use".
