The dollar spot "Sclerotinia homeocarpa" is one of the diseases that cause more inconveniences and economic investments for its control, causing dependence on the repeated use of fungicides, forcing to alternate these treatments because it develops a capacity of resistance to treatments current.

The symptoms of the disease are clear, during the months of spring to autumn, yellow spots appear on the lawn between 2 and 12 centimeters, almost always oval or round with a coin shape, where the margins of the circle are usually of reddish brown color and in the early hours of the day cobwebs are observed on the stain.

This important disease affects a wide variety of grass types from the Agrostis, Festuca rubra, Poa annua, Poa pratensis, Lolium perenne, Festuca, Cynodon dactylon, Eremochloa ophiuroides and Zoysia families. These varieties of grass are the most used in sports on grass such as golf courses, football, hockey, polo, tennis, rugby, etc.

From ZonoSistem we have verified with a treatment to the lawn of a golf course, that after 15 days of applying the ozone treatment simply by spraying the stains, it can be seen in the images how it is drastically reduced, practically eliminating it.
