There is different kinds of adjuvant:
1. Surfactants (also called spreaders or wetting agents)
An adjuvant that reduces surface surface tension between the spray solution droplets and the pest target’s surface, thus providing greater coverage.
2. Crop Oil Concentrates
A combination of oil (petroleum or vegetable) and surfactants/emulsifiers. Crop oil concentrates act as penetrants, stickers, spreaders (limited), humectants, etc.
3. Methylated or Ethylated Seed Oils
An emulsified methylated or ethylated seed oil. Act as penetrants, spreaders (limited), humectants, etc.
Enhance uptake of pesticides through target pests surfaces.
Combine spreading and adhesive qualities to improve coverage and retention of pesticide.
Increase the drying time of spray solutions which provides greater time for the pesticide to enter the targets surface. Used during high temperature, low humidity and low spray volume situations.
7. Drift Control Agents
Reduces the amount of fine spray particles that carry pesticide out of target areas. (polyacrylimides, encapsulators, others)
Used to alter the color of spray solutions.
