Choice Weather Master

Choice Weather Master is a water conditioning agent for use with agricultural chemicals. Designed for hard water conditions, this liquid formulation locks up hard water cations allowing maximum herbicide performance. Compatible with all formulations of glyphosate.

Key benefits 

  • Reduces the effects of hard water on herbicide performance. When certain herbicide chemistries are added to water the negative charges in the herbicide molecules attract the positive ions (cations) in the water. The herbicide and these cations form a strong complex which can prevent or hinder uptake of the herbicide into the plant, effectively reducing herbicide performance.

  • Multiple sequestering and complexing agents bind multiple hard water cations, such as calcium, manganese, magnesium and potassium.

  • Liquid formulations provide the convenience of using a liquid formulation instead of having to dissolve dry product

  • ALWAYS add Choice Weather Master to the spray tank BEFORE adding pesticides.
