California Tree Nut Growers Now Have Systemic Copper in Their Toolboxes with Instill bactericide and fungicide

Visalia, Calif., February 21, 2019 – Tree nut producers in California now have access to a more effective, longer-lasting copper bactericide and fungicide.

“The key difference is that this is a systemic copper,” says Sym-Agro President Peter Bierma. “Instead of providing a protective coating, Instill absorbs into the tree to provide protection from the inside out.”

Instill’s formulation makes the copper more active, so much lower doses of copper are required to provide the same level of disease control. Added to that, when Instill moves into the tree cuticle, the copper can’t be washed off, providing up to 21 days of residual control.

For example, pistachios need copper nutrition, and using Instill as a copper fungicide choice will help satisfy this need without adding any cost. Instill provides growers innovative new use options for copper, with effective disease control for superior end products.

Instill is the only copper that provides immediate copper nutrition. Instill is true copper nutrition – it’s in a form that trees can use, so it doesn’t have to be converted in the soil or pulled into the roots over time. It won’t wash into the soil or increase detrimental copper loading.

Key benefits include:

  • Reduced phytotoxicity due to systemic/translocating technology
  • Tank mix options –due to lower pH
  • Complete tree protection from systemic movement
  • No visible residue on treated surfaces
  • Easy to handle – mixes easily and stays in solution
  • Rain-fast –after Instill dries, it will NOT wash off
  • Reduced potential for russeting from copper residue on tree surface

Instill’s novel inside-out systemic activity protects against, downy mildew, bacteria blights, fire blight,  powdery mildew, botrytis and rust. It helps reduce post-harvest rots and can be used up to the day of harvest.

Prior to receiving California registration, Instill has already been in use in most fruit and vegetable growing regions with great success. In the high-value greenhouse industry, Instill is marketed as Phyton, with a proven record of safety and high efficacy.
