<p>Its been a year! What have you done to protect your grapevine from the powdery/downy mildew? Spraying sulfur is about the best and easiest method of powdery mildew prevention. Begin spraying soon after bud break and continue on a regular routine of about every ten days. Sulfur will not cure powdery mildew, but it can prevent it. You can control the disease by spraying before, during and after the blooming period. And if nothing works, consulting <a href="https://www.rosevillecapestcontrol.com/">Loomis pest control</a> is the best solution.</p>
