Limitations, Restrictions, and Exceptions


Use Quali-Pro Chlorpyrifos 4E to control ant species (except fire ants, carpenter ants, harvester ants, and pharaoh ants) by applying the specified dose in 25 or more gallons of water with ground application equipment that will uniformly apply the spray to the orchard floor. Do not allow spray to contact foliage or fruit. To control foraging ants, apply Quali-Pro Chlorpyrifos 4E to the orchard floor at the rate of 3/4 to 1 quart (0.75 to 1 lb. a.i.) per acre. Repeat as needed. For best insect control, uniform coverage of the orchard floor is necessary. Do not apply where weed growth or other obstructions would impede uniform coverage of the orchard floor. Do not apply in tank mixtures with Evik herbicide. Foliar applications of Quali-Pro Chlorpyrifos 4E may be made in addition to the orchard floor, but must comply with the 10-day re-treatment interval.

Quali-Pro Chlorpyrifos 4E may also be applied to citrus orchard floors through sprinkler irrigation systems only if the system uniformly covers the soil surface at the base of the tree. Use the listed amount of Quali-Pro Chlorpyrifos 4E per acre. See SPRINKLER IRRIGATION section for further information.

RESTRICTIONS: Do not allow livestock or dairy animals to graze in treated areas. Do not make more than 3 applications per year (does not include foliar applications to citrus trees). Do not make a second application within 10 days of the first application.
