Is this a good spray for the lawn for moss in the Northwest?
Roger H on Feb 26, 2016
BEST ANSWER: I'm not sure, since the label doesn't mention any application directions for use on lawns. Since it is a violation of Federal Law to use the product in a manner inconsistent with its labeling, I'd have to recommend finding a spray that is specifically intended for use on lawns to control moss.
How effective is this product on Japanese Beetles and Stink Bugs?
MATTHEW R on Jun 4, 2016
BEST ANSWER: Horticultural/dormant oil works by suffocating overwintering pests in trees as well as their eggs and larvae. Pests like Japanese beetles don't overwinter in trees (they come up from the ground), so this may not be the most effective spray for your needs. I'd suggest a pest control that works on contact, like GardenTech?? Sevin?? Bug Killer, instead.
