Carb-O-Nator Mode of Action
Carb-O-Nator deploys a multi-site mode of action, acting through a combination of osmotic pressure, pH and specific ion effects. It acts very rapidly to cause dehydration and total collapse of spores and the mycelium of susceptible fungi.
Time application of Carb-O-Nator at the first sign of disease.
Mix at a rate of 2.5 to 5.0 lbs./A in 100 gallons of water. Apply mixed spray solution to thoroughly wet stems and foliage of plants. Apply a minimum of 20 gallons of mixed spray solution per acre.
Concentration of spray solution and frequency of application will depend upon disease pressure. Repeat application at 10 to 14 day intervals or as needed.
Always read and carefully follow label instructions. Note that California registered uses are listed in a separate section of the product label.
