Utah Lawn Diseases

With the warmer May weather, you may think that you would see more signs of diseases or insects on you Utah lawn. The truth, however, is that many of the common diseases and insects do not appear until later in the year. They become dormant during the winter and do not revive until the warmer temperatures of summer.

You may see signs of cranberry girdler, sod worm or white grub this month if the weather is unusually warm, but this is rare. One disease you may see in May is actually a carry over from the winter months. There is a type of mold that can grow if the previous winter saw a rapid change in temperature between freezing and thawing. Your grass may appear to be “melting out” and have a purple tinge on the edges.

Mostly May is about prevention. You will want to train your lawn’s roots and create a mowing regimen that will encourage growth and discourage lawn care problems. A pre-emergent herbicide can also help keep your lawn green and healthy.

Utah Lawn Care: Powdery Mildew

Most diseases that affect the lawn prepare to become dormant in the fall. Depending on weather conditions, some diseases may appear. Utah lawn care may include treating diseases even in the fall, especially powdery mildew.

Powdery mildew is created from several different types of fungi. It can attack many different types of plants and grasses, and can spread quickly. It first appears as white powdery spots on the blade that changes to tan as the spores are reproduced asexually.

Powdery mildew usually lies dormant in the winter and will start to spread as the cool, humid temperatures of spring signal the beginning of its next growth cycle. It also likes moderate humid temperatures with plenty of cloud cover, which is why you may see a reemergence of the disease in the fall.

A nitrogen fertilizer applied in the spring can help to prevent the growth of powdery mildew.  Many different fungicides can help eliminate the disease if repeated over time. If the disease persists or resists treatment, you can contact us for help. Turf Plus can help with Utah lawn care such as powdery mildew. We can inspect your lawn to determine if it is contaminated with powdery mildew or other disease and treat your lawn to make sure it is healthy in the spring for a new year of growth.

Utah Lawn Care Issues: Dealing with Rust

When the weather turns cool most Utah lawn diseases start to drop off. One Utah lawn care issue that a homeowner may have to deal with in September, however is rust. This disease gets its name from the reddish brown spores that are kicked up when people and animals travel across an infected lawn. These spores are created by a fungus that thrives in the late summer, early fall. This is when lawn growth slows down and cool nights with warm sunny days encourages damp patches of grass that are slow to dry.

The more humid the weather the better chance that rust may be an issue. You may see the fungus begin in shady areas where the grass is wet for longer periods during the day. If you have nights with cool temperatures and a lot of dew coupled with sunny days that are relatively warm, you may want to keep an eye out for signs of rust as well.

A fungicide such as daconil or bayleton is the preferred treatment for rust. Apply the fungicide once or twice a month until all signs of the disease are eliminated. If you want to prevent the growth of rust or other diseases, there are some preventive methods you can use to make your lawn care duties lighter.

Applying the right amount of fertilizer will help encourage a healthy lawn and discourages many weeds, insects and diseases. In the fall, make sure you water less but mow more. When you water the lawn, make sure to irrigate in the morning to give the grass time to dry in the sun and prevent moisture from developing overnight.

If these lawn tips don’t prevent the growth of rust or other Utah lawn care issues, please contact us and we will be able to help you get your lawn back in shape for fall.

How to Detect and Treat Necrotic Ring

Necrotic Ring is a disease that typically affects lawns during the hottest months of the year, when the grass is under the most stress. It can be identified by donut-shaped rings between one to five feet in diameter. These patches can be localized or seen throughout your lawn.

This disease is caused by a fungus known as Ophiosphaerella korrae, and is common in areas with poor drainage and compact soil. Over watering is another common instigator that will encourage the growth of this fungus.

There are some types of grass that are more resistant to Necrotic Ring than others are. Rye grass and certain types of Kentucky bluegrass are resilient and will resist the spread of Necrotic Ring. In fact, you can seed affect areas of a lawn with rye grass seed to encourage lawn growth.

Other ways to prevent the growth and spread of Necrotic ring are good lawn maintenance practices and prevention. Good lawn maintenance includes not overwatering your lawn, and only mowing the top 1/3 of a blade of grass at time by using the second highest setting on your lawn mower. Be cautious when applying fertilizer that is high in nitrogen to help curb the growth of Necrotic Ring and use slow release fertilizers over multiple application over the summer months.

Applying fertilizer in the late spring and early fall can help reduce the growth of Necrotic Ring, and applying Sulfur amendments when fertilizing can also help prevent the growth of fungus on your lawn.

If you decide to apply a fungicide, you need to make sure you time the applications carefully to get the proper affect. Apply the first dose in approximately mid-May, followed by a second application in the middle of June. This makes sure that the fungicide is still working during the peak time when fungus grows on your lawn.

With careful planning and maintenance, you can prevent Necrotic Ring and other diseases from affecting your lawn, and keep it healthy all year round.
