BONIDE Captain Jack's Liquid Copper Fungicide Concentrate - Description
Active Ingredient: Copper Octanoate (Copper Soap), 10.00% (1.8% metallic copper equivalent)
This versatile copper fungicide can be applied during both the dormant and growing seasons, making it a reliable year-round disease management tool. When used according to label directions, it's safe to apply up to the day of harvest — though some rose varieties and certain grape or apple varieties may be sensitive to copper sprays, so it's worth testing on a small area first if you're treating a sensitive variety.
