Product Features & Benefits

At the recommeded use of 0.25 - 0.50% per 100 gallons STEPGROW CT:

  • Acts as an acidifying agent to reduce pesticide decomposition and boost efficacy
  • Lowers the pH of the tank solution to prevent alkaline hydrolysis
  • Enables uniformity of the pesticide solution to maximize crop protection dollars
  • Optimizes compatibility to prevent undesired precipitation that can lead to plugging of sprayer lines

Technical Details & Test Data

Suspension Concentrate Diluted 100% in 8-16-8 Fertilizer

Dilution of suspension concentrate in an 8-16-8 fertilizer causes immediate flocculation that settles out over the course of 30 minutes. The images and graph below demonstrate how the addition of STEPGROW CT allows the pesticide to stay suspended in the solution and remain stable, while three commercially available adjuvants are unable to prevent pesticide precipitation.

Tank Mix of Suspension Concentrates and Soluble Liquid Products

The tank mix of suspension concentrates and soluble liquid products separates immediately. The images below show how the addition of a commercially available adjuvant improves short-term performance. STEPGROW CT has superior initial stability and maintains pesticide suspension in solution, enabling long-term stability up to 24 hours.

Storage & Handling

Storage & Handling
  • Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling STEPGROW CT. Contact with eyes and skin should be avoided. Wash thoroughly after handling materials. See the Safety Data Sheet (SDS) for further information.
  • Bulk Storage Recommendations: Elevated storage temperature may be desirable to maintain ease of pumping, but the product should be stored at ambient temperature.
  • Non-Bulk Storage Recommendations: STEPGROW CT which has been stored in drums at temperatures below -11°F (-24°C) may thicken or solidify. It may be fluidized by warming with a drum heater or in a steam room. Drums should be vented prior to heating to avoid excessive pressure build up. Product temperatures over 130°F (54°C) are not recommended.
