Prime Source PS 804 Surfactants - 2.5 Gallons
804 Select™ combines the effects of a surfactant, penetrant, acidifier
& deposition aid in one convenient, economical formulation.
to increase the coverage on a target surface area and penetration
through waxy or weather hardened cuticles, PS 804 Select ensures more
complete uptake of the applied active ingredient.
PS 804 Select
delivers economy by adding penetrating and acidifying qualities to a
traditional deposition aid. It is also extremely user friendly with its
ability to disperse in cold water.
Increases the surface area a spray will cover
Improves penetration into substrate
Reduces drift by helping to create the optimal droplet size
Moderate acidifier to enhance tank mix stability
Low foaming formulation to assist with initial tank mixing
Disperses in to cold water
Especially beneficial when used with weak acid herbicides

a surfactant, PS 804 Select works to lower the surface tension of water
droplets, allowing for better product coverage on the target surface.
Direct benefits of surfactants include, facilitating uniform droplet
spread of a spray solution, softening protective waxy layers on plants
and bringing water into contact with water-repellent surfaces. In
general, the addition of a surfactant to a tank mix, significantly
improves its performance, by allowing the applied active to come in
direct contact with a greater percentage of the plant’s surface area.
804 Select improves the infiltration of active ingredients into the
target pest or plant. Penetrants use different blends to soften, soak
through and dissolve waxy, protective layers. They also help spray
solutions move through and around bark-like coatings as well as wet
protective hair-like coatings and keep them saturated with actives.
Increased penetration leads to greater control of pests and limits
PS 804 Select contains
dilute solutions of acids to contribute additional hydrogen ions to a
spray solution, thereby decreasing the pH of the solution. pH
modification can improve solubility of active ingredients, prevent
mixing complications and increase the half-life performance of spray
actives. This can result in better product performance and reduced
stress on application equipment. Acidifiers are especially beneficial
when used with weak acid products, such as glyphosate.
not entirely eliminating drift, PS 804 Select improves the accuracy of
spray applications by increasing the percentage of droplets that conform
to the ideal size range as they pass through a spray system. Consistent
droplet size maximizes pesticide distribution throughout the spray,
while reducing the amount of waste associated with drift.
When adding to a tank mix, always add PS 804 Select last.
