What do i set the dial at. I want to spray Roses for pests and diseases.
The Monterey Horticultural Oil should be able to be used in most spray equipment including hose end sprayers. We do not carry the Ortho Dial sprayer so we cannot tell you what setting you should put it on other than whatever will give you the correct dilution ratio the label suggest you use for the diease you are trying to prevent against or treat for. Please check the Product Label for specific usasge instructions.
