INSTILL is a broad-spectrum systemic bactericide + fungicide labeled for use on fruits, vegetables, and herbs. Its patented chemistry speeds absorption into plants, enabling its active ingredient to move into and throughout the plant and be retained in the bio-system for up to 21 days. The INSTILL formulation is a solution (not a suspension) that leaves no visible residue.
The systemic difference – INSTILL is a copper sulfate pentahydrate, which is double chelated, allowing the copper to safely cross the plant membrane and enter the tissue and vascular system. The second benefit is a mordant effect, which draws the pathogen to the copper ions for higher efficacy. INSTILL’s formulation is acidic, and the ideal spray solution pH at application is 5.5 – 6.5. The lower pH creates an osmotic pull from the plant to draw the copper into the treated tissue. It is considered a chemotherapeutic composition for the control of plant diseases caused by mycoplasma-like organisms and works quite differently than other low dose or metallic coppers.
