Lime Sulfur Sprays
Well I had never heard of a lime sulfur spray before visiting my friend Mark Greene. According to the Internet,
“Objective of lime sulfur spray at is to reduce fungal inoculum on canes.”
From what I’ve read it seems to be sprayed most often when the vines are dormant. Most say to spray before bud swell.
And here is an image of the product and also a link to the label.
