Limitations, Restrictions, and Exceptions

ALFALFA - APHIDS (SUPPRESSION)

NOTE: Use higher rates to control spotted alfalfa aphid in California and Nevada. Stubble spray may be applied to control leafhopper in the Northeast.

Mix the required dosage with enough water to ensure thorough coverage of crop foliage and apply using aerial (fixed-wing or helicopter) or power-operated ground spray equipment. For aerial application, use 2 to 5 gallons of water per acre. For best coverage when using ground application, a minimum of 20 gallons of water per acre with hollow cone nozzles is recommended. Control may be reduced at low spray volumes under high temperature and wind conditions. Treat when field counts or crop injury indicates that damaging pest populations are developing or present; however, do not apply more than once per crop cutting. Some reduction in insect control may be evident under excessively cool conditions. For Egyptian alfalfa weevil control in California, apply the specified dosage in a minimum of 5 gallons of water per acre when larvae are actively feeding and populations reach 15 to 20 larvae per 180° sweep with a 15-inch diameter net.

QP Chlorpyrifos 4E may also be applied through sprinkler irrigation systems as a postemergence broadcast application to control the listed foliar pests. For best results, use the recommended rate of QP Chlorpyrifos 4E per acre. Maintain vigorous tank agitation to assure uniformity of the application throughout the injection period. See SPRINKLER IRRIGATION section for further information.

QP Chlorpyrifos 4E should not be tank mixed with pesticides, surfactants, or fertilizer formulations unless prior use has shown the combination noninjurious under your current conditions of use. Some phytotoxic symptoms may be observed on young, tender, rapidly growing alfalfa when treated with QP Chlorpyrifos 4E. Alfalfa will outgrow the symptoms and no yield loss should be expected.

This product is highly toxic to bees exposed to direct treatment on alfalfa. Do not apply if nearby bees are clustered outside of hives and bees are foraging. Protective information may be obtained from your agricultural extension service.

RESTRICTIONS: Do not cut or graze treated alfalfa within 7 days after application of 1/2 pint of QP Chlorpyrifos 4E per acre, within 14 days after application of 1 pint per acre, or within 21 days after application of rates above 1 pint per acre. To avoid contamination of irrigation floodwaters, do not flood irrigate within 24 hours following an application of QP Chlorpyrifos 4E.
