Aside from thethe usual suspects listed above, grass fungus can come in many forms and strike at various times of the year in a variety of conditions. That being said, like any living organism, a lawn that’s healthy and strong stands the best chance of fighting off these disruptive diseases. The preventive benefits offered to plants remain as long as the fungicide doesn’t get degraded by environmental elements such as sunlight or washed off by irrigation, wind, or rain. Repeated applications are therefore essential to ensure that the fungicide stays on the plant and continues to provide protection from fungi. List Of Fungicides And Uses In The US Best chemical prime source propiconazole developed to overcome this issue. This chemical will kill and harm fungus present in the debris. Lawn rust thrives on stressed, unhealthy grass and is especially common during summer periods of drought. As such, it’s important to take particular care during the summer months, when hot weather and reduced rainfall can have asignificant impact.
Azoxystrobin is one of the most powerful ingredients against many diseases, and Artavia 2 SC is a terrific broad-spectrum liquid fungicide. Apply just 0.38-0.77 oz. per 1,000 for 10-28 days of disease coverage (depending on the type of fungus). Try our Azoxystrobin calculator to help get the exact amount you need for your lawn.Many of these are beneficial, but there are also pathogens that if left will multiply uncontrollably and cause various maladies to the grass of your turf.
Every grass type has own water requirements. Lawn grasses need water but overwatering can make them susceptible for fungus. Some obligate(only live on host) species of fungus are also highly active and infect a large number of plants both in the field or garden. DOW Eagle 20EW is my first option in terms of lawn fungicides. I’ve used it many times when my lawn was affected by the Brown patch and always had the best results. The life cycle of the fungus is interesting and aid in controlling. Unlike bacterial or viral spread cycles, the fungus has a designed cycle by nature. All the struggle seems to fade away, however, when a friend or neighbor praises your lovely green lawn.

Propiconazole is often combined with azoxystrobin to prevent and treat these lawn diseases. Propiconazole and azoxystrobin are two popular modes that work well in rotation. This fungus overwinters on debris and infected leaves so remove them from the field. There are different chemical or plant fungicides available in the market. Snow mould develops under prolonged snow cover. The combination under snow of a fairly constant temperature of about 0°C (32°F) and increased levels of carbon dioxide are particularly favourable for Microdochium nivale. Another fungal disease called grey snow mould, caused by Typhula incarnata, can also develop under these conditions. The patch symptoms are similar but any fungal growth seen is greyish-white rather than pink. Typhula also produces tiny, brown, hard resting bodies, often looking like small seeds, scattered over the affected grass.
Hollow tine lawn aeration is the removal of small plugs from the lawn. This eases compaction and sub-surface thatch, allowing air, water and fertiliser to penetrate down to the root zone, particularly useful at the beginning and the end of the growing season. A lawn aerator can also help the lawn through drought stress conditions, enabling water retention in the central root zone. Overseeding Spectracide Immunox Fungus Plus can prevent and control a large spectrum of grass diseases caused by fungi.
