Pesticide laws in Oklahoma differ from those of other states because application of insecticides below labeled rates is not allowed. Thus, use of reduced rates of any product or products, including use of hopper blends (i.e., half rates of hydramethylnon plus methoprene baits) is not allowed until registered as use directions by manufacturers in the state (i.e, Extinguish Plus* is now fully registered and available as a hopper blend for use in Oklahoma).
