Proliant delivers

  • More yield, bigger roots
  • Increased kernel rows in corn and better tip fill
  • Increased silage tonnage



  • Supplements the plant’s natural GA3 production during slow growth stages
  • Temporarily increases plant growth rate
  • Increases early season photoradiation capture of the treated crop – more photosynthetic capacity

Yield challenge

With the ongoing drive for higher yields, many growers feel that they have hit a plateau in their corn,cereal and forage yields. Genetics, fertility and pest control can only bring a crop so far, especially when that crop faces adverse weather conditions that cannot be controlled.

Nufarm solution

Proliant is a new plant growth regulator that delivers powerful stress mitigation through a unique, patented, high purity formulation. It increases early season growth of corn, cereals and grass crops. The active ingredient, gibberellic acid (GA3), is a natural plant growth hormone that elongates plant cells and encourages cell division. The results are larger roots, stronger stalks and a plant that can handle stresses more effectively.

Usage information

  • For best results, the water pH should be around neutral, and always below 8.5
  • In many cases, performance is increased if application is made under slow drying conditions and/or addition of a non-ionic surfactant at 0.125% v/v
  • Can be applied with most herbicides, fungicides and foliar nutrients (Check with your Nufarm representative for compatibility questions)
