Limitations, Restrictions, and Exceptions


Foliar Spray:

Mix the required dosage in sufficient water to ensure thorough and complete coverage of the foliage and crop, and apply as a concentrate or dilute spray using conventional, power-operated spray equipment. For dilute sprays applied to tree nut crops, mix the required dosage in sufficient water to allow for spray to runoff. For concentrate sprays, apply an equivalent amount of Quali-Pro Chlorpyrifos 4E per acre. Treat when pests appear or in accordance with local conditions. Insect control by aerial application may be less than control by ground application because of less coverage. Consult your State Agricultural Experiment Station, certified pest control advisor, or Extension Service specialist for specific use information in your area. To avoid contamination of irrigation floodwaters, do not flood irrigate within 24 hours following an application of Quali-Pro Chlorpyrifos 4E. Quali-Pro Chlorpyrifos 4E is highly toxic to bees exposed to direct treatment. Do not apply when bees are actively foraging in the treated area.

Do not allow livestock to graze in treated orchards. Do not make a second application within 10 days of the first application. Do not aerially apply this product in Mississippi.
