Lowes Lawn Fungus Control: Scotts, Bayer, Spectracide

It’s easier to prevent lawn diseases than to cure them. There are many types of lawn fungus that can pose a threat to your lawn. Cool or warm temperatures, over or under fertilization, and watering all can contribute to lawn fungus or lawn disease.
Nutrient deficiencies can also weaken grass, so Lowes recommends to feed your lawn at least 2 times per year to keep your lawn strong and vigorous. Some fungus diseases like heavily fertilized lawns, while others prefer an underfertilized lawn. If your lawn use involves kids, pets and parties, you should probably feed 3-4 times per year with Scotts or Sta Green Fertilizer. Some diseases even prefer a certain soil pH.
Applying the recommended amounts of the correct fertilizer and making adjustments will greatly reduce chances of lawn disease. And don’t forget to do a lawn ph soil test yearly.

When it comes to lawn fungus, you may not know that all lawns are naturally full of fungi and spores. Some are harmless and some will give your problems.  The right or wrong conditions can cause grass fungus to turn into a harmful disease quickly. The most common causes of a lawn fungal disease are:

  • Drought
  • Mowing too low
  • Compacted soil
  • Overwatering
  • Too much fertilizer
  • Wrong grass type for your yard
  • Warm temperatures and high humidity

Common Lawn Diseases

There are quite a few lawn fungal diseases that can affect your lawns. They target specific lawn types, at certain times of year, under certain conditions. Common fungus and lawn diseases:

  • Brown patch  during hot and humid weather.
  • Fusarium blight prefers hot, drought conditions.
  • Dollar spot when nights are cool and morning dew is heavy.

To control common lawn diseases such as brown patch and dollar spot, apply a fungicide made for lawns. Scotts Lawn Fungus Control, Bayer Advanced Fungus Control for Lawns and Spectracide Immunox Fungus plus Insect Control are available at most Lowes stores. They provide systemic disease prevention and control. You can apply any time on all lawn types. Just be sure to follow the directions on the label. Following these basic guidelines for a strong lawn will help you protect your lawn from fungal diseases. A nourished lawn is also better able to fend off diseases.

I usually see best results when using the granular form.  All three brands will come in granular or liquid. For best results, repeat at 3 week intervals. During periods of high day and night temperature and humidity, two week treatment intervals may be needed to achieve best brown patch control. Maximum number of applications is 4 per year. Do not apply more than 2.7 lb. Lawn Fungus Control per 1,000 sq. ft. of turf.

  • Apply to dry foliage at the STATED LABEL RATE every 20 to 30 days beginning in late spring to early summer.
  • Water-in immediately after application and keep turf from becoming drought stressed by watering 1 inch weekly

Lawn fungus disease usually will appear in mid to late summer.  Along with lawn insect control problems, fungus needs to be treated before a problem appears. Please follow all label directions and be very careful when applying. Make sure children and pets stay away when you apply it. Keep pets such as cats and dogs out of the treated area until the application has been watered in and allowed to dry.
Also, when your lawn is suffering from a lawn disease or fungus, it is best to bag lawn mower clippings rather than mulch them or leave on the ground. Bagging clippings will help minimize the potential for the fungus to spread.
