When is it best to treat pine trees with Bonide Liquid Copper Fungicide Concentrate?


When you apply Bonide Liquid Copper Fungicide Concentrate will depend on the disease you are treating. If you are treating pine trees for needle blight, then you would apply when new needles are just emerging. Mix at a rate of 0.5 to 2.0 fl oz in one gallon of water, and spray until needles are thoroughly wet with spray. Please see the product label for complete application instructions.
