I have dead spots all over my yard It’s dying from the top of the blade down. is it fungus or insects
There are small dead spots all over the yard it has been raining a lot and really wet. I have applied a insecticide and it did not help.
There are 3 types of fungus that can be the causes and their is a general group known as “water molds,” which are diseases known scientifically as Pythium and Phytophthora species. Both of these diseases produce mobile spores that can swim through the water and attack the roots of lawn plants as well as annuals and vegetable plants. These diseases cause what is commonly known as damping-off and root rot. Usually when these diseases attack, you will notice reddish to brown lesions just below the green part of the leaves. Then the entire plant wilts. The plant can be pulled easily out of the soil as the roots are slimy. These plants are dead and you will have to reseed in September with resistant varieties.
Check with your County Extension Office for the best seed to use in your area.
