Pest and Fungus Prevention
First, prevent water stress on your lawn. Turf that is water stressed attracts chinch bugs. Next treat your lawn – especially stressed areas – with a good insecticide focusing on the edges of the damage not the center. The new pyrethroids are excellent and come in many formulations. Bifenthrin and Permethrin are active ingredients in insecticides sold for chinch bug control at Lowes and Home Depot. They do a good job at killing existing chinch bugs but have little if any residual control. Monthly applications during the warm months are required to protect your lawn from chinch bugs. Using a spray service for 40.00 dollars a month can save you 3,000.00 dollars worth of turf damage.
The best plan for dealing with lawn fungus is to do everything you can to prevent it. By the time you see noticeable signs that lawn fungus has infiltrated your lawn, it will probably be extremely difficult to control. More than half your lawn you may be destroyed seemingly overnight. Few fungal spores have easy fixes, but most instances of lawn fungus can be avoided with a few lawn maintenance tips.
The most common mistake homeowners make is to overwater their lawn. It seems counterintuitive, especially during the hot, summer months, but overwatering your lawn can be more harmful to your lawn that not watering it at all. Just as important as how much you water your lawn is the time of day you do it. Most homeowners water their lawn when they get home from work or later in the evening. This can leave your lawn damp for hours, allowing fungus to get a foothold in your yard. Watering your lawn in the morning will allow the sun to quickly evaporate any excess water. If you don't have the schedule and/or the discipline to water your lawn in the morning, you should invest in a lawn irrigation system with a timer. These systems are going to be cheaper in the long run than treating your lawn for disease.
If you see these you are watering to much!!!!
