1. Leaf Spot is a fungal disease that attacks various plants and trees. This disease appears in spring when the climate is moist, rainy, and has humidity in the air. The physical appearance is shown with various brown spots and can range in size. Leaf spots can weaken plants, which attracts greater damage from pests and insects.

2. Spring Dead Spot is a very damaging disease of bermudagrass. The physical appearance of this disease is usually circular patches of bleached and sunken dead grass. The circular patches can range in sizes. Re-growth of affected areas is very slow and often need immediate assistance.

3. Red Thread is a fungal disease that appears when the temperature is high in humidity and is ranging from 68 to 75 degrees. Red Thread will form discoloration in the lawn showing reddish and pink tips on the grass blades.
