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

Visalia, Calif., February 5, 2019 – Producers in California now have access to a more effective, longer-lasting copper bactericide and fungicide – Instill protects nut trees, fruit trees, citrus, leafy vegetables and berries.

“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 plant to provide protection from the inside out.”

Instill provides growers innovative new use options for copper, with effective disease control for superior end products. For example, pistachios need copper nutrition, and using Instill as a copper fungicide choice will help satisfy this need without adding any cost. For leafy vegetable and berry growers, Instill provides a flexibility they haven’t had – Instill leaves no visible residue, making it possible to apply copper even very close to harvest.

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 plant cuticle, the copper can’t be washed off, providing up to 21 days of residual control.

Instill is the only copper that provides immediate copper nutrition. Instill is true copper nutrition – it’s in a form that plants 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 plant 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 plant 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.
