I have a client with a brown patch problem that needs quick attention. My supplier has recommended Cleary 3336 and the yard is 14k. I don't have a spray rig yet and wondered about using a hose end sprayer with wettable powder. A friend that has been in the business for several years with more spraying experience than I thought that it would work. He recommended putting the packet in the sprayer and let the water do the work as it comes through. Will this work? If not, why not? Thanks.
