Key Benefits of Lime-Sulfur Solution
Mode of Action
Lime-Sulfur Solution works on contact. It is highly alkaline, so when it contacts a Chasmothecium, Lime-Sulfur Solution can penetrate the Chasmothecium’s outer shell. The ascospores inside are destroyed before they can germinate and infect new tissue.
The particle size of the colloidal sulfur in Lime-Sulfur Solution is so fine (0.0002 microns) that it is 20 times smaller than micronized sulfurs. The small particle size allows Lime-Sulfur Solution to more evenly cover targeted surfaces.
Lime-Sulfur Solution penetrates and sticks to plant surfaces. Once it dries, rainfall and other moisture will not wash it off. Because it is available on the bark for a long period, it provides a residual effect and extends your protection against powdery mildew.
A dormant application of Lime-Sulfur Solution is a first-step approach to a solid preventative powdery mildew program. Because Lime-Sulfur Solution is not temperature driven, it can be applied any time during the dormant stage. It is important to time applications well before spring rains or periods when unseasonably warm weather may trigger bud break. Do not apply after bud break when leaf expansion is occurring or damage will likely occur.
In addition to Powdery Mildew, Lime-Sulfur Solution controls Coyneum Blight, Scale Insects, Peach Twig Borer, Leaf Curl, Silver Mites, Brown Mites and Red Mites.
