I picked up a Hudson "Cameleon" model 62104 hose end sprayer to do some major moss killing in the lawn this weekend. http://www.hdhudson.com/consumer-sprayers/consumer-products/product/product-details/?id=176 I'm going to use Lilly Miller liquid moss killer with the hose sprayer. The moss killer bottle says to mix the ratio as 8 oz per 3 gallons of water. Well, I've read all the info in the sprayer's instructions, and even looked at Hudson's website and elsewhere on the 'net, but can't determine if the mixing setting numbers on the sprayer dial mean oz used per gallon of water going through the sprayer, or something else. Seems like the setting values on the sprayer dial would be the mix ratio per 1 gallon of water ... just a guess since I can't find anything that tells me. So do I set the sprayer to "8 oz", assuming hose sprayers are calibrated on the dial for 3 gallons of water? Or do you think the setting should be set based on one gallon of water? I can't believe the manufacture can't give this info someplace so the user at least knows what ratio is really taking place with a particular dial setting.
