Generally the lower dosages given will be satisfactory for young, succulent growth of sensitive weed species. For less sensitive species and under conditions where control is more difficult, the higher dosages will be needed.

Apply Dri-Clean during warm weather when weeds are young and growing actively. Use enough spray volume for uniform coverage by ground or air application. Unless otherwise recommended, suggested application rates may be up to 10 gallons of total spray by air or 5 to 25 gallons by ground application equipment. If only bands or rows are treated, leaving middles untreated, the dosage per crop per acre is reduced proportionately. Do not apply when temperature exceeds 90°F.

TO PREPARE THE SPRAY: Mix Dri-Clean Herbicide only with water. Just add the recommended water to your spray tank, then remove the water soluble packet from plastic outer bag. Add the appropriate Dri-Clean into the spray tank and agitate for three to five minutes. Dri-Clean will make a stable water mixture. It is non-flammable. Do not handle water soluble bags or expose them to moisture since this may cause rupturing.

Individual water soluble bags are not to be offered for sale.

Notes: (1) Adding oil, wetting agent, or other surfactant to the spray may be used to increase effectiveness on weeds, but doing so may reduce selectivity to crops resulting in crop damage. (2) One 2 lb. 13 oz. (45 oz.) packet of Riverdale Dri-Clean Herbicide is equal to 5 pints of 2,4-D “4 lb.” Amine. (3) Using a 2 lb. 13 oz. (45 oz.) packet for a 5 acre coverage is equivalent to applying 2,4-D “4 lb.” Amine at a rate of 1 pint per acre.

Limitations, Restrictions, and Exceptions


STONE FRUIT, PISTACHIOS, AND NUT ORCHARDS: Broadleaf Weeds. Use 27 ozs. in 10 to 100 gallons of water per acre of ground to be sprayed. For band or spot treatment, calculate rates according to the actual portion of an acre treated.

Apply as a directed spray onto the weeds to point of runoff when weeds are young and actively growing (pre-bud to early bud stage). Make up to two applications through the dormant or growing seasons as needed. Do not harvest stone fruits within 40 days of application. Do not harvest nuts within 60 days of application. Do not graze or feed cover crops from treated orchards to livestock.

PRECAUTIONS IN APPLYING 2,4-D IN ORCHARDS AND VINEYARDS: Apply only after irrigation and allow maximum time before the next irrigation. Do not apply around fruit trees or vines with hand gun. Use only on flat, fan-type nozzles and low pressures - 20 to 25 lbs. Use a lined boom applicator which can be calibrated and which will deposit the spray uniformly. Avoid contact with fruit, foliage, stems or lower limbs of trees or vines. Apply precisely and uniformly to prevent damage to the trees or vines and to obtain satisfactory weed control. Do not apply during windy periods or extremely high temperatures. Do not spray bare ground. To avoid leaching, do not apply to dry soils. Apply when soil is moist and do not irrigate for 5 to 7 days after application.
