2,4-D is an effective control for broadleaf weeds when used according to manufacturers instructions. These diseases can be caused by over-managing, and backing off on water and fertilizer can usually take care of many problems. A new disease, Zoysia Patch, has been identified which includes symptoms of large, round patches of thin turf from 1-20 feet in diameter. Zoysia Patch does not kill the lawn, merely thins it out. Usually, Zoysia lawns are relatively disease free.
Frequency depends on the time of year and fertilization program.
After a thick green appearance is established, one application every year or two is adequate. Though daily watering during the first 6 weeks to 3 months of establishment is critical, once established, Zoysia turf requires little or infrequent watering. Zoysia rate very high on the list of drought tolerant species. In fact, in a study at the Texas Agricultural Experiment Station, only Buffalograss rated lower for the least amount of potential evapotranspiration rates. All Rights Reserved.
