What is drift?
Drift is the unintentional, off-target application of crop protection products. Factors such as severe temperatures, high wind speeds, nozzles used, and small droplet size can increase drift and decrease performance of crop protection products. Drift control agents are especially important to use near sensitive sites to prevent damage to surrounding crops and when facing less than ideal weather conditions.
Drift control agents can help to improve the precise placement of a pesticide spray by increasing the spray droplet size. Larger droplets remain on leaves longer and spread better than smaller droplets, helping with improved foliar intake. Consult the product label for information about optimal droplet size and calibration of nozzles. Drift control agents are the most common adjuvant used with crop protection products, and some new dicamba herbicides even require an approved drift reduction agent (DRA) in the tank mix.
Deposition Aids (Stickers)
Deposition aids, or stickers, are often used to increase the ability of water-soluble pesticide particles to stick to a plant’s surface, reducing evaporation for a waterproof coating. This stickiness helps to keep the particles in place through rain and irrigation, while preventing degradation from UV rays. Deposition aids are one of the most used adjuvants on the market, and many include a surfactant for better coverage and stickiness on a target surface.

Petrichor® improves coverage and deposition and reduces off-site drift of pesticides being applied by ground or air.
- Industry leading drift and deposition agent.
- Low 3 oz./Acre use rate is equivalent to industry standard of 4 oz.
- Made with highly refined soybean oil for enhanced performance, storage stability, and mixing.
When selecting adjuvants, the decision should always be based on agronomically sound information and customer needs, including the site to be sprayed, the target pest, and the equipment to be used.
