How Do You Use Lime Sulfur Spray?
Lime sulfur spray is both a fungicide and pesticide that gardeners have been using since the mid-19th century. This strong chemical is yellowish orange and has an extremely pungent odor. It can be used on various types of fruit trees, shrubs and shade trees. Gardeners use lime sulfur to eliminate insects including scale, mites and borers. Moreover, it can effectively control certain plant diseases such as leaf blotch, nectria canker, anthracnose, apple rust, peach leaf curl, black spot and maple gall. Because of its high toxicity, special handling and storage are required. Mix lime sulfur with water in a pressure sprayer.
