STIMULATE™ is a highly concentrated microbial liquid formulation of naturally occurring strains of beneficial microorganisms specifically selected to convert unavailable nutrients to usable forms and produce natural substances that work together to enhance soil and plant health. STIMULATE™ contains a unique rhizobial inoculant that improves nodulation and nitrogen utilization in legumes. STIMULATE™ can be applied to the seed, soil, or foliage at any growth stage with positive benefits. STIMULATE™ works continually from application to harvest to improve plant health and yield.

CONTROL DUO™ is a very effective, easy-to-use, multifunctional adjuvant that provides superior drift mitigation and enhanced pesticide uptake. CONTROL DUO™ mitigates drift by increasing deposition and retention while significantly lowering evaporation. The premium surfactant system in CONTROL DUO™ improves penetration of pesticides, nutritionals, and biologicals. CONTROL DUO™ contains the research and field proven CONTROL WM™ polymer blend in combination with a unique and highly effective surfactant system. The unique surfactant system in CONTROL DUO™ produces less driftable droplets than most surfactants.

CONTROL DUO

TRI-PLEX™ is an easy-to-use, multifunctional adjuvant for use with glyphosate, dicamba and other pesticides. TRI-PLEX™ deactivates hard water ions including Ca, Mg and Fe to improve pesticide performance. TRI-PLEX™ contains the research and field proven CONTROL WM™ polymer blend that reduces drift, allowing more pesticide to reach the target. TRI-PLEX™ also provides significantly higher retention of spray solution on plant surfaces. TRI-PLEX™ reduces evaporation of the spray droplet in the air and on the leaf surface allowing better uptake into the plant. The concentrated all-in-one formulation provides water conditioning, surfactant, and a drift mitigation adjuvant blend in one convenient package. TRI-PLEX™ is compatible with all pesticide formulations. TRI-PLEX™ recommended rate is 2 to 6 qt/100 gal. TRI-PLEX™ is approved with dicamba and 2,4-D formulations.

TRI-PLEX

IMPROVE is a concentrated, high-quality surfactant blend that provides top performance in research and normal use. IMPROVE Is excellent at wetting and plant absorption enhancing the performance of herbicides and pesticides. IMPROVE contains proprietary humectants that keep the spray deposit moist longer, allowing for extended up take and rewetting. IMPROVE also includes a unique and very effective defoaming system. IMPROVE does not contain isopropyl alcohol or fatty acids as "active ingredients" as many surfactant products do.

IMPROVE

DIGEST™ biological crop residue and stubble digester is a highly concentrated, diverse formulation with dozens of naturally occurring strains of beneficial microorganisms. Aerial applications before harvest have proven very effective. DIGEST™ is a complete formulation with microbes specifically selected to only degrade tough dead plant residues including lignin, hemicellulose, and cellulose. The balance is "cafeteria" microbes that produce nutrients to feed the digestion microbes. DIGEST™ enhances plant nutrition by decomposing crop residues to give a continual release of tied-up nutrients throughout the growing season. Plants treated with DIGEST™ have shown increased nutritional feed value in lab tests. Another benefit is a reduction of surface germinating volunteer corn and weed seed. Less residue also means more uniform seed placement.
