Cotton root rot has been recorded on exotic pines such as Eldarica or Aleppo. Therefore, the roots should be checked. When taking root samples, it is also a good time to check soil moisture. Helminthosporium Blight and Curvularia affect hybrid Bermuda in the low desert when the turf is water stressed and has a thick thatch layer. These diseases are prevented by proper irrigation and mowing.
Fungicides are effective for control when integrated with cultural practices.
These fungi become severe pathogens when turf is water stressed and nitrogen deficient and can often be controlled with cultural practices. Disease has been most prevalent in shady areas or in other poor growing conditions. Pythium has been a problem in several locations on bentgrass, causing severe root pruning. If fungicides are used in a disease management program on turf, it is important to know which pathogens are active in order to apply effective products at the right time. Resistance management is always important, so remember to alternate fungicides.
