Battling Brown Rot in Your Peach Crop? Heed These Tips To Succeed
Dr. David Ritchie, like other peach growers in North Carolina, is dealing with a heightened risk of brown rot due to the recent rain events in the orchards at the N.C. State University Sandhills Research Station. He provides the following guidance to growers interested in providing the best fruit protection from brown rot.
For brown rot on varieties that are within 1 to 2 weeks of harvest, apply up to two applications of Merivon (BASF) or Miravis (Syngenta) or Luna Sensation (Bayer Crop Science) at 7-day intervals if we stay in a wet period.
Pristine (BASF) also is an option if you cannot get one of the other three. Do not use more than two consecutive Merivon or Miravis or Luna Sensation sprays on the same variety to reduce the risk of resistance developing.
For later ripening varieties, maintaining cover sprays is very important if rainy periods continue. Any damage to fruit that occurred from the spring freezes is enhancing the conditions for the fungus to infect the fruit.
