• Downy mildew has been detected in Echols County in cucumber. Weather conditions have been favorable for downy mildew infection in southern Georgia particularly in cucumber and squash. It is the matter of time when it will show up in other southern counties. Hence,  I would suggest our cucurbit growers to look for the downy mildew symptoms in their fields and start applying protective spray of…

  • I am hesitant to post anything on this as it changes constantly. In the latest court case with chlorpyrifos, the prior elimination of the tolerances by the earlier court was struck down. While it is complicated and can change rapidly, the current interpretation is that all tolerances are back in place, making labeled uses of…

  • Propulse has received a label expansion on watermelon against Fusarium wilt. Propulse is a pre-mix of Proline and Luna (effective on nematodes too). In my field trials in 2018-19, it did as well as Miravis Prime and Proline program.

  • Onion downy mildew has been detected on onion in Tattnall County. These observations indicate that inoculum of downy mildew is currently in southern GA counties and under favorable conditions potential disease outbreak in onion crop can occur.  Fungicide program containing Omega 500, Ridomil Gold Copper, Zampro, Phosphite and Bravo would help in reducing disease severity.

  • Downy mildew has been detected on cucumber in Brooks County by Mr. Will Brown. These observations indicate that inoculum of downy mildew is currently in southern GA counties and under favorable conditions potential disease outbreak in cucurbit crops can occur. I would suggest our cucurbit growers to look for the downy mildew symptoms in their fields and start applying protective spray of below stated fungicides. Watermelon: Rotation (foliar application)  with …

  • Downy mildew has been detected in North Florida. Weather conditions have been favorable for downy mildew infection in southern Georgia particularly in cucumber and squash. It is the matter of time when it will show up in our southern counties. Hence,  I would suggest our cucurbit growers to look for the downy mildew symptoms in their fields and start applying protective spray of…

  • Downy mildew was confirmed from the Tattnall County in Georgia on Vidalia Onion. The conditions currently are suitable for the infection and spread of the downy mildew pathogen. We urge growers to scout their crop routinely for any suspicious symptoms and contact their local county extension agent for further confirmation. The treatment options are moderate…

  • Vegetable growers will start transplanting their crops soon. In order to reduce risk of introducing soil-borne pathogens in field it is important to screen your transplants before for symptoms particularly those that are caused by Pythium, Fusarium, Rhizoctonia. If the seedlings appear diseased, identification of the problem is critical. Do not transplant seedlings from trays…

  • If you are not aware, EPA has been petitioned to revoke all tolerances and cancel all associated registrations for food uses of multiple (pretty much all) organophosphate pesticides. This would include acephate (orthene), diazinon, malathion, naled (dibrom) and others. This would eliminate our last broad spectrum soil insecticide in vegetables (diazinon; I do not consider…

  • Based on the multi-year field screens that were conducted in 2019-2021 in Tifton there are handful for commercially acceptable snap bean varieties with at least moderate-level of resistance to cucurbit leaf crumple disease. There were no varieties with high-level of resistance. Of those with moderate-level of resistance there were several from Harris Moran, Syngenta, Seminis…
