severe

Target pest	Location	Rate	Unit	Dilution	Label notes
Pythium blight, cottony blight, grease spot, spot blight, root rot, crown rot and damping-off disease caused by Pythium spp.	Outdoor	1.5 to 3	fl. ozs.	2 to 5 gallons of water	apply to 1000 sq. ft.; Begin applications at first sign of disease and retreat at 10 to 14 day intervals as needed. Within the rate range given, use the lower rate for the shortest interval listed and the higher rate for the longest interval. Under severe conditions, use the highest rate and shortest interval specified. Do not exceed 3.0 fl. ozs. per 1000 sq. ft. per application or 7 fl. ozs. per 1000 sq. ft. per year. The interval between applications may not be less than 10 days.

ORNAMENTALS (Bed and Bench Grown Plants)

Target pest	Location	Rate	Unit	Dilution	Label notes
