    Hoping it works!

    By Mississippi on 10/20/2017

    I was diagnosed with large patch disease (rhizoctonia) in my centipede lawn by the extension service representative in September 2017. I had large patches, some 20 ft in diameter of dead and dying grass. The rep. suggested using Bayleton. I had previously treated these areas wth a granular product I picked up at Lowe's. It certainly didn't stop my problem from getting worse. I treated the first time on the first of October 2017. I did the second treatment on the 20th of October. In between treatments hurricane Nate came through and did quite a lot of damage to my yard. While doing the second treatment I looked closely at the affected areas and the surrounding healthy areas. At the second treatment it appears the Bayleton stopped the progression of the fungus into non-affected areas. The turf in the badly affected areas are not showing any significant signs of recovery. In those areas the affected turf is still dry in appearance, yellow blades and not showing any new growth. It is towards the end of our growing season so I don't expect much new growth but healthy turf is still growing so I'm not sure how well this is working so far. The product is easy to use. I use a kitchen scale to measure out the exact amount recommended and mix it in a 4 gallon back pack sprayer. I treat approximately 1,000 sq. ft. with one mix. The product dissolves readily in the water and doesn't foam too bad. Will have to report back an a week or so after the second treatment to see how it goes.

Questions & Answers

Have a question about this product?
Is Bayer Bayleton 50 Fungicide WSP effective in controlling Western gall rust in Monterey Pine trees?

Bayer Bayleton 50 Fungicide WSP is one of the few fungicides labeled for Western gall rust (Endocronartium Harknessii). However, the product label does not indicate efficacy on this specific tree. Bayleton cannot be applied to pine seedlings or seed in nurseries in the State of California. This article from the USDA gives more information about control of this disease. We would also recommend speaking with your local Cooperative Extension or Ag Department for further recommendations in your area.

Amount of Bayleton 50 Fungicide WSP for 9 gallon spray tank? Treating bermuda decline.

Bayleton 50 Fungicide WSP would be mixed at the rate of 1-2 oz per 1000 sqft for bermuda decline prevention and 2 oz for curative. For residential lawns you do not exceed 1.5 oz per 1000 sqft.  Apply the specified amount of BAYLETON 50 Turf and Ornamental Fungicide using 2 to 4 gal of spray per 1,000 sq ft for this specific disease.  This product is really more for larger areas that commercial companies would treat multiple lawns a day so it is not easy to break down into smaller amounts with the packets since they are pre-measured.

So to accurately cover 18000 sqft you would need to use at least 36 gallons of water, not 9.  And use 18 oz of product which equals a little over 3 packets at the lower rate.  It might be best to break up the area in sections to apply so that you can use the right amount of water.  Even then you may need to spray with just water to ensure it is sufficient enough.
