Anyone used tempo SC Ultra out of a backpack sprayer to kill bagworms in small trees, under 15 feet tall? Label says 45ml (1.5 fl oz) per 100 gallons water. A customer told me today a local dealer told him to spray at 1 oz. tempo per 2 gallons and add acephate (cant remember how much) and spray to almost run-off. He said dealer said it wont hurt the tree at all. This seems a little strong to me on the tempo.
