![]() Although both have been used for more than 30 years, resistance has not developed to etridiazole (ai for Terrazole, Truban and Banrot). Both of these products are industry standards. The best product overall was Terrazole at 92 percent control in eight trials with Subdue MAXX, providing an average of 65 percent control in 21 trials. The Pythium species included in the IR-4 trials were aphanidermatum, dissoticum, irregulare, mammilatum, ultimum and vipa. Unfortunately very few products give us better than 50 percent control of Pythium root rot and sometimes efficacy is affected by the exact species of pythium involved. The IR-4 program (provides data for specialty crops product registration) supported trials on Pythium control for several years and came out with a summary of that work in the middle of 2011 (Table 1). We are still looking for more products that are highly effective on Pythium diseases. Over the past few years, we have seen quite a few new fungicides registered that are labeled for Phytophthora and downy mildew, but few labeled for Pythium diseases. ![]() But sometimes use of a fungicide or biological product is needed. root loss - outer core can die leaving just the coreĪvoiding disease through the use of pathogen-free plugs and liners, new potting media and pots and using the amount of water and fertilizer for optimal crop production, help to minimize Pythium losses.wilting - can recover overnight sometimes.chlorosis - yellowing, especially on lower leaves.Symptoms of Pythium infection are variable and can include: Pythium diseases are very common on ornamentals and one of the most reported diseases when it comes to both preventive and curative fungicide applications. When looking for how to control pythium, specific fungicides that focus on Pythium are highly recommended when treating either preventatively or curatively, as this is a very unique disease.Wilting on part of a coneflower shows typical Pythium root rot symptoms. When disease IS active, make sure you treat with a curative fungicide before mowing or going over the turf, as Pythium is easily spread and does damage very quickly. Doing your best to minimize humidity and saturation with excessive daily watering can be very helpful in preventing disease as well. When looking for how to control Pythium disease, your best option is to identify if you have susceptible grass types or plants, and to treat preventatively starting before the weather conditions become ideal for the disease. Pythium blight is also very common to find in on immature grass that was planted in the spring, because it simply isn’t strong enough in midsummer to naturally resist the disease. Bentgrass is highly susceptible to Pythium, particularly when kept wet in an attempt to prevent drought stress. Pythium is mainly a summertime disease that happens when night temperatures stay in the 70’s and high humidity is present. ![]() In addition to the tell-tale black residue, white mycelium that looks like fine white hairs coming off the grass blade can be visible in the early morning. Pythium in turf is often called grease spot, as affected leaf tissue gets matted down with a black, sticky residue. Pythium blight and Pythium rot are soil borne diseases that can affect both roots and leaf tissue.
