    Does anyone have a preventive brown patch program?
    If so how is it set up. I will start one soon the brown patch
    is becoming a serious problem. And just spaying it when the
    problem comes up it not working year after year. The same
    accounts are having promblems.

    Here is one that has been recommended. 1st the preventative, then the chemicals. Look up the labels on the Internet for turf types and rates. Fungicides are typically very expensive and hard to get a homeowner to bite since multiple treatments are required every 7 days or so.
    Avoid heavy, early spring and summer fertilization, particularly with soluble nitrogen.

    Avoid over fertilization of turfgrasses growing in shaded areas.

    Use slow-release nitrogen fertilizers. Fertilize to maintain adequate but not lush growth during the growing season. Properly fertilized turf will recover quicker from disease injury than will under-fertilized turf.

    Remove and dispose of clippings from infected areas or when conditions are conducive to disease development. Mulching mowers that chop clippings to 1/4 inch or less do not contribute to brown patch development.

    Prune woody landscape plantings and trees to allow better air movement and light penetration to reach the turfgrass canopy.

    Water infrequently, but deeply, in the early morning, and avoid late evening and night watering.

    When available, plant turfgrass cultivars with a known level of resistance to brown patch.

    Use a preventive fungicide program on high-value turfs with a history of brown patch. On other turfs, apply a registered fungicide at first evidence of the disease. Integrate fungicide treatments with other management practices to maximize their effectiveness.

    Provide good surface and subsurface water drainage to reduce humidity in the turf canopy.

    Manually remove dew in early morning by dragging a garden hose or rope laterally across the grass.

    Annually aerify to reduce thatch buildup.

    Man did you dig that list up from the stonage? We do a previtive program
    starting may 10th and treat every 28 days with a rotation of Heritage(syngenta) baner maxx (syngenta) we also add daconil (syngenta) for commercial properties. Most customers get 4-5 per season. The heritage also works great on pythium which is becoming more and more a problem. We charge 1.5 times the regular app price.

    I have done one fungicide treatment. I find if you correctly apply fert, water, mow at the correct height etc, fungus is a very minor problem. I would feel terrible tacking on 4 or 5 additional treatments that could be widely prevented by proper maintenance.

    You might like to throw BASF Inginia in the mix,,residential approved and effects Dollar spot also. Heritage has no effect on DS.

    I'm guessing you're dealing with centipede lawns. I've had good results with broadcasting Bayleton in late April and a follow-up 28 days later. This gets us through the summer and then apply once more in mid-September.
  8. So what type of grass are you dealing with?
