Rainfall and humidity, together with mild temperatures can promote the development of lawn diseases such as fusarium, brown patch, dollar spot and (the difficult to pronounce) helminthosporium.
» Symptoms of lawn diseases can include grass leaves or patches of lawn turning yellow or brown or dead areas developing.
» To help reduce the incidence of lawn disease, only water the lawn in the morning, which gives the grass a chance to dry off during the day. Wet foliage overnight can exacerbate diseases.
» Also, if the soil under the lawn is compacted or poorly drained, which can lead to more moisture pooling on the soil surface and promote diseases, aerating the soil using a garden fork or a lawn corer can help.
» To control common lawn diseases apply Yates Mancozeb Plus over the lawn using a sprayer.
