Will this help if the trees leaves are curled and have black spots?
Carmella W on Aug 6, 2016
BEST ANSWER: Thank you for your question. In order to help you, we need to know what kind of tree is having the problem you describe. Could you please supply that information?
How is this applied to the tree? What is the dilution ration? Will it control brown fruit rot on a nectarine tree in Alabama?
Jamie S on Mar 25, 2016
BEST ANSWER: It is a liquid concentrate that you will mix with water and put in a tank-type sprayer to make an application (either in the fall or the spring depending on your needs). It does control fungal issues like brown rot in nectarine trees, and the instructions recommend 3 ?? teaspoons per application. This and other specific-use information is included on the product label for your convenience.
Does this product work on apple rust?
artistfaith on Jun 1, 2016
BEST ANSWER: I have two apple trees in my backyard. During 2014, one of the apple trees, golden delicious suffered extensive rust, so I ordered this fungicide from Stark Brothers and sprayed the diseased apple tree. The fungicide was quite effective, most of the rust was gone, and the tree is healthy again.
How to dispose of it properly if left over?
Judy G on May 20, 2018
BEST ANSWER: Instructions for disposal, depending on whether or not there is any product remaining in the container, can be found on the label. //www.bonide.com/assets/Products/Labels/l879.pdf
can this be used for grapes, have a fungus on some kind, black spots on canes?
CHARLES G on Mar 20, 2018
BEST ANSWER: I have used this product on plum and cherry trees for black knot along with pruning.
Unfortunately, I have no experience on grape vines. Remember a few things that should carry over.
First, the fungus should be pruned off and go roughly eight inches away as it will travel through the plant. Second, do not compost the pruned material or leave it lying in a brush pile. Burn it up or haul it away. Third, your spores have to come from some place. Do an inventory around your property. Vines often grow from birds along fences or even under trees. If those vines have fungus, the fungus needs to be removed to eradicate the source of your fungus. In the spring and especially in a wet spring, the spores seem to spread more readily.
Will this fungicide prevent fire blight on pear trees?
james q on May 21, 2016
BEST ANSWER: No, fire blight is a bacterial disease. A high elemental copper spray during early spring through 1/2" green tip will help. You can also apply streptomycin during bloom.
What's the shelf life of this product? How long can it sit in my garden shed and still be effective once opened?
Alison B on Dec 29, 2017
BEST ANSWER: If you have prolonged periods of freezing weather, the product will not perform as well after being frozen. If it's not frozen, it is shelf-stable for about 2 years. It's also advisable to keep it from being exposed to excessive heat.
