Adjuvant for low temperature water
We manufacture and sell a hydrophilic wettable powder insecticide (diatomaceous earth), it's OMRI, EPA and 50 state approved for use on crops. Applications can be up to 50 lbs per 100 gallons per acre. We recommend a non-ionic adjuvant to improve spray pattern and leaf wetting. e.g. APOE such as Spreader 90 or organo-silicone such as Brandt 719. Application is easy in all areas except when the grower uses cold water (~5 C), then they have issues to stir in our product. What cold-water non-ionic wetting agent would you recommend for fruit tree growers in the Pacific Northwest ?
