In the past week or so I have received numerous calls about bermudagrass that was brown\/dying in hay fields and pastures.\u00a0Many\u00a0cases\u00a0have been\u00a0caused by damage from the Bermudagrass Stem Maggot (BSM). However, I have seen just as many cases that were caused by leaf spot and leaf rust.<\/p>\n

A closer look\u00a0at the leaf blades will reveal the\u00a0lesions created by these fungal diseases.<\/p>\n

Weather conditions this year have been especially conducive to disease development, but the problem is also tied to potash deficiency. Soil tests may show adequate levels of potassium, but they can be misleading. Submit a plant tissue sample instead to determine if potassium levels are low. We can send\u00a0soil and tissue samples to the UGA labs\u00a0from our office for a small fee. Nutrients are removed in a 4:1:3 of N-P-K as hay. This means that you must add at least 75% as much potash as you do nitrogen each season. Splitting fertilizer applications is more effective in the sandy soils of our region.<\/p>\n

The problem has been worst on Alicia. Other bermudagrass varieties typically have enough resistance bred into them to avoid\u00a0severe\u00a0epidemics. If the problem is\u00a0severe, cutting and removing the hay (if possible), and fertilizing low fertility fields\u00a0to\u00a0promote healthy regrowth\u00a0is an option. This may allow for better grazing conditions, but producing another hay crop\u00a0will be difficult. Grazing the fields is an option also. The hay\/forage will certainly be lower in quality, and you may see some refusal from animals. However, it may be the best utilization of the resource since we are so late in the year.<\/p>\n

Burning is recommended every 1-3 years. Make sure to burn\u00a0the field in February\/March\u00a0to\u00a0reduce the amount\u00a0of disease present in the field next year. The disease survives from year to year in the dead plant material (thatch layer) so destroying it by burning is crucial.<\/p>\n
