Remember those brown spots in your Bermuda grass lawn this past spring? It’s a common lawn disease called Spring Dead Spot, and September through October is the time to help combat the problem with applications of lawn fungicides.
Spring Dead Spot is caused by a fungus (known as ophiosphaerella korrae), which infects Bermuda grass roots during the fall. The fungus will kill crowns, stolons, or rhizomes of the infected plants. Certain varieties of Bermuda grass are more prone to the disease than others, and there are also many factors which affect why some lawns have a problem and others don’t.
How to keep your lawn dead spot free
Maintaining good soil fertility, proper soil pH in the 5.8-6.5 range, proper mowing, watering, and aeration are all important in a Spring Dead Spot management program. Applying nitrogen fertilizer too late in the growing season, and/or in heavy amounts, will cause a higher incidence of Spring Dead Spot.
This is why the specialists at LawnAmerica cut down on the amount of nitrogen come the fall. While we could keep your lawn green well into October and November with a heavy nitrogen application, that’s not what’s best for the lawn’s health. Too much of a good thing (nitrogen) can sometimes be as bad as not enough.
Applying Lawn Fungicides
We have had success over the last few years using Velista Fungicide in helping to improve Bermuda grass response to Spring Dead Spot. While it does not prevent every dead spot, it will lessen the severity of the disease, and we tend to see much faster re-growth the following spring.
Two treatments about 28 days apart are required for effective control. Contact us today if you need more information on this service, or any other lawn care treatment solutions.
