Plants in the landscape and garden can seem to go from thriving to struggling overnight. What is causing your plants to wilt, turn yellow, turn brown, or grow spots? Plant disease experts with the MSU Extension Service can help you determine what is happening and how to manage it. Get science-based information about bacterial blights, mold, and fungi direct from our website or from your local Extension agent or specialist!
Two half-day training sessions next month will provide expertise on pest and disease control on small farms.
MSU scientists are on the lookout for a cucurbit crop bandit. And they need your help!

CRYSTAL SPRINGS, Miss. -- When impatiens planted as part of a Mississippi State University variety trial died within two weeks, researchers acted quickly and described a pathogen never before seen in this flower.
"We were growing SunPatiens, which are hybrid impatiens immune to downy mildew. This disease has been a big problem for the industry," Broderick said. "The plants were doing really well, but in July they started to look like they were wilting. The stems were collapsing and dying, and in a two-week period, they went from looking relatively healthy to dead."
