pesticide's physical properties and/or enhances its performance.
1)Utility agent
2)Spray modifier
Utility agents - Answers - -Aid mixing in the spray tank
-Ex) Compatibility agents, pH buffering agent, anti-foaming agents
Spray modifiers - Answers - -Aid spray application & coverage
Drift reduction additives - Answers - Increase droplet size and reduce drift
Surfactants - Answers - Help individual spray droplets spread out on the treated surface
Stickers - Answers - Improve pesticide adherence to the treated surface
