Ultra 90 Surfactant


Ultra 90 Surfactant improves the effectiveness of foliar sprays, including insecticides, fungicides, and foliar fertilizer applications. Allows spraying applications to stick to plants and dry faster, improving coverage and reducing leaf runoff. 1 pint. Mixing rate: 1/2 oz per gallon of water.


Ultra 90 Surfactant improves the wetting of plant foliage and enhances the effectiveness of spray applications for insecticides and fungicides. This product contains hygroscopic materials which improve the drying speed of pesticides and foliar sprays on vegetable leaves. This increased drying time is particularly important and effective when spraying in narrow weather windows when rain may be imminent.

Ultra 90 Surfactant can be used with most pesticides and foliar nutrient sprays. This product increases the ability of sprays to stick to plant leaves, increasing the effectiveness of the sprays and reducing leaf runoff. This is particularly useful when spraying insecticides that require the insect to ingest the plant.

For insecticides like our Spinosad Garden Insect Spray, it will improve the ability of the insecticide when treating corn earworms by spraying the silks of the corn plant. The surfactant will allow the product to stick the corn silks, which will in turn provide a greater control on the earworms as they attempt to enter and feed on the ear of corn.

It also extremely helpful when spraying fungicides where coating the entire plant is necessary for effective control. This will provide a great control for fungal diseases like powdery mildew and downy mildew. This product will not cause excessive foaming in the spraying tank and it will not cause spraying equipment to corrode.
