Prime Source PS 804 Surfactant

PS 804 SELECT is a multi-tasking adjuvant team that conditions the carrier water and spreads the spray solution thoroughly on the target surface. PS 804 Select is recommended for use in agricultural and industrial applications to enhance the efficacy of the active ingredient. PS 804 SELECT improves penetration of the active ingredient through waxy, resistant epicuticular tissue for more complete uptake and transport to the mode of action site. Without altering the viscosity of the spray solution, PS 804 SELECT helps to form spray droplets that are able to resist pump shear and remain within the optimum range for best deposition and reduced drift away from the intended target.

Surfactant

As 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.

Penetrant

PS 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 herbicide resistance.

Acidifier

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.

Deposition Aid

While 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.

MIXING INSTRUCTIONS

• When adding to a tank mix, always add PS 804 Select last
• In general, follow the W-A-L-E-S plan when adding herbicides to a tank mix
• Wettable Powders (WP) then Flowables (F,DF)
• Agitate then add adjuvants such as anti-foaming compound & buffers
• Liquid and Soluble products
• Emulsifiable concentrates (EC)
• PS 804 Select or other adjuvants
