How much Orthene WSP do I apply to large ornamental holly bushes to get ride of a bad case of cottony camellia scale?


Per the Orthene Turf Tree and Ornamental WSP Product Label: To treat for scale you will use 10 2/3 oz (2/3 lb) per 100 gallons of water. This would be about 0.11 oz per gallon of water. Scale:Apply as crawlers begin to appear. Repeat applications, at a 2 week or more interval, may be necessary where there is continuous crawler production.
