Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Vapors from the product may injure susceptible plants in the immediate vicinity. Use care to avoid spray contact or drift to 2,4-D susceptible plants such as cotton, tomatoes, flowers, okra, grapes, fruit trees and ornamentals. Do not permit spray mist containing this product to drift onto them. Do not spray when the wind is blowing towards susceptible crops or ornamental plants. Use coarse sprays and/or low spray pressure to minimize spray drift. Do not apply with hollow cone type insecti.:i::e or other nozzles that produce fine spray droplets. Spray drift can be lessened JI keeping the spray boom as low as possible, by spraying when wind velocity is low, by j'2!:::reasing the pounds of pressure of the nozzle tips, and by stopping all spraying when ·nc exceeds 6 to 7 miles per hour. On cropland and along roadsides, do ~t exceed 20 psi pressure. Do not apply when a temperature air inversion exists. I questios exist pertaining to the existence of an inversion, consult with local wea~~?r servces before making an application. Do not use the same spray equipment for applY~~4 other ••• materials to 2,4-0 susceptible crops as injury may result.

Riverdale 33-8 is mO'ce effective than 2.4-0 amines for controlling hard-to-kill weeds such as field bL1dweed. ;<..ls&ian knapweed, Canada thistle, leafy spurge. cattails, tules and nutgrass. Riverdale· 638 Broadleaf Herbicide should be applied when daytime temperatures are lower than 80 to 85 degrees. Spraying when temperatures are higher may cause rapid foliar burn and decrease the effectiveness of Riverdale 638. Treatment at higher temperatures also increases the possibility of crop injury.

Riverdale 638 Broadleaf Herbicide s(/<-{ Page 5 INJURY TO CROPS FROM THIS HERBICIDE MAY OCCUR. DEGREE OF CROP INJURY, DO NOT USE THIS PRODUCT. IF YOU ARE NOT PREPARED TO ACCEPT SOME Crop varieties vary in response to 2,4-D and some are easily injured. Apply Riverdale 638 only to varieties known to be tolerant to 2,4-D. If you are uncertain concerning tolerant varieties or local use situations that may affect crop tolerance to 2,4-D, consult your seed company or State Agricultural Extension Service for advice. MIXING INSTRUCTIONS Add one-half the required amount of water to the spray tank, then add the Riverdale 638 with agitation, and finally, the balance of the water with continued agitation. Provide continuous agitation to insure uniform spray mixtures. Use spray mixture as soon as possible after mixing. COMPATIBILITY If Riverdale 638 is to be tank mixed with fertilizers or with other pesticides, compatibility should be tested prior to mixing. To test for compatibility, use a small container and mix a small amount (0.5 to 1 quart) of spray, combining all ingredients in the same ratio as the anticipated use. If any indications of physical incompatibility develop, do not use this mixture for spraying. Indications of incompatibility usually will appear within 5 to 15 minutes after mixing. Read and follow the label of each tank­ mix product used for precautionary statements, directions for use, geographic and other restrictions. COMBINATION WITB LIQUID NITROGEN FERTILIZER Use the recommended amount of Riverdale 638 Broadleaf Herbicide per acre for weeding and feeding corn, small grains, grasses for production or grass pastures as directed on this label. Use the fertilizer at rates recommended by supplier or Extension Service Specialist. Fill the spray tank about half full with the liquid fertilizer, then add the Riverdale 638 with vigorous agitation, and complete filling the tank. Apply immediately and continue agitation in the spray tank during application. Do not allow mixture to stand overnight. NOTE: Fertilizers can increase foliage contact burn of herbicides. Reducing the fertilizer rate and concentration will reduce the hazard of leaf burn.
