Fruit Tree and Plant Guard Concentrate is one of many great products we carry for scab on pecan trees and should do a great job for you when used as directed on the product label.
Fruit Tree and Plant Guard Concentrate contains synthetic ingredients and is not organic or natural.
Unfortunately, Fruit Tree and Plant Guard Concentrate is not labeled for grapes. You do not state what you are treating for, but we would most likely would recommend a product such as Bonide Fruit Tree Spray which would treat the same things as the product you are currently asking about.
On the Fruit Tree and Plant Guard Concentrate product label, spp stands for all species in that given genus.
