We have a serious leaves.curl desease on my peach tree, now is early June fruits already form , is it too late to apply the copper fungide treatment ?
Anh T on Jun 5, 2016
BEST ANSWER: Once symptoms of leaf curl appear, it is too late to control the disease that season. Fungicides are not effective against this particular disease after budbreak. Prune your tree this fall, remove and destroy the fallen leaves and pruning debris, and then make your leaf curl application (as directed by the product label) while the tree is dormant.
how much do i use to spray peach trees?
silviodenunzio on Mar 21, 2016
BEST ANSWER: I have only used it on very young trees (apple, pear, peach and cherry). I mix the powder iwith water in a spray bottle and spray the leaves and stems/trunk with the spray so that a thin layer of spray is left behind. When it dries it looks like a dusting of powder. If you use too much it will just wash off in the next rain, so that is not a big problem (except wasting the product/money). The product is essentially non-toxic, so it will harm other vegetation when it washes out, and it will not pollute waterways (unless you dump the whole container in a stream, but who would do that!). Too little (if you can't see the dusting at all when dry) will not give you protection. Good luck and happy peaches!
how much does one bottle make in gallons?
Lisa B on May 9, 2016
BEST ANSWER: There is no way to offer this information accurately because, depending on what you're spraying (apple tree, blueberry plant, etc.), the amount of product you use per gallon of water varies to a great degree. Take a look at the label here:
Will these sprays hurt birds?

Can you use copper spray after the cherry tree has bloomed?
Cheryl D on Apr 19, 2016
You need to wait until the petals have fallen and the pollinators have stopped visiting the tree.
Then you will need to follow the directions carefully. Although copper is "organic" (it's really "inorganic", though) you still to be careful when handling it and spraying because it is toxic.
