Rust is another common lawn disease. If you find your leaf blades turning orange or rusty, it is likely that Rust has appeared in your lawn. Rust is often found in Ryegrasses and Kentucky Bluegrass. Morning dew, shade, high soil compaction, and low fertility are factors that contribute to its growth. To determine if your lawn is infected with Rust, you can take a white tissue or paper towel and rub a few grass blades with it. If the orange or rusty color remains, it is most probably Rust.

The best way of getting rid of rust is by aerating your lawn. You should water your lawn well in the morning hours and reduce shade to the grasses. You should also mow your lawn more frequently with bagging of the grasses. In addition, you can increase the nitrogen level of the soil by following a regular fertilization schedule. If you intend to use fungicides, you can try Triadimefon and Anilazine.

Red Thread is characterized by the pinkish-red thread that forms around the leaf blades binding them together. Grasses infected by Red Thread will turn brown very soon. The red threads are most visible when the lawn grasses are wet.

By aerating more often as well as removing thatches in your lawn, you can quite easily put Red Threads under control. If you prefer the use of fungicide, you can consider the use of Chlorothalonil.
