|I have gray spot on my lawn. Pyricularia Grisca. I have tried cornmeal and sodium bicarbonate to no avail. What organics can I put on my lawn to alleviate this gray spot?|
|You've tried all the organic controls I know of so you may need to resort to using a commercially prepared product. Several fungicides are recommended for gray leaf spot control, including azoxystrobin (Heritage), myclobutanil (Spectracide Immunox, Eagle), propiconazole (Fertilome Systemic Fungicide, Ortho Lawn Disease Control, Bannar Maxx), and thiophanate-methyl (Green Light Systemic Fungicide, Ferti-lome Halt Systemic Fungicide, Scotts Lawn Fungus Control, Bonide Bonomyl Turf and Ornamental).
