Texas bluegrass, scientifically known as Poa arachnifera, requires prevention against several pests and diseases. One of the common diseases affecting this plant is leaf spot, caused by the fungus Drechslera poae. Leaf spot appears as small, dark spots on the leaves, eventually leading to withering and death of the plant. To prevent leaf spot, it is important to maintain proper plant hygiene by removing infected leaves and avoiding overhead watering, as the fungus thrives in moist conditions. Fungicides can also be used as a preventive measure.
The next disease is powdery mildew, caused by the fungus Erysiphe graminis. Powdery mildew white, powdery coating the leaves, stems, and flowers the grass. It can cause stunted yellowing. To prevent, provide good air and water properly. Fungicides control.

Texas bluegrass needs prevention against leaf spot, powdery mildew and bluegrass billbug. Good plant care, air circulation, and lawn practices help stay healthy.
