Stanley Culpepper, University of Georgia (UGA) Cooperative Extension weed specialist, warns growers to exercise caution when managing wild radish as it has become resistant to some fungicides. Culpepper says, “Wild radish has certainly been a challenge for us in some cropping systems for my 23 years. If you’re looking at burn-down for cotton, it’s huge, it’s a challenge, it’s difficult to manage. If you’re growing broccoli, cabbage or cauliflower, it’s a challenge. There’s no doubt”
