GBNBRAL XNPORMATION 
Riverdale lOt Dacthal Granules is a granular selective herbicide formulation for use as a 
pre-effiergent application for control of crabgrass and other annual grasses and for certain 
broadleaf weeds i~ flower and vegetable gardens and ornamental turf. 
lOt Dacthal Granules is recommended for use on Turf; Home Flower Gardens; Nursery Stock; 
Strawberries; Seeded Crops: beans (dry and snap), broccoli, brussels sprouts, cabbage, 
cauliflower, collards, cucumbers, garlic, horseradish, kale, melons (cantaloupe, honeydew, 
watermelon), mustard greens, onions, ?Otatoes (whole and cut pieces), Southern peas (black 
-eyed), soybeans, squash (Winter and Summer), turnip greens and turnips; Transplant Crops: 
broccol~, brussels sprouts, cabbage, cauliflower, eggplant, garlic, peppers, onions, sweet 
potatoes, tomatoes and yams. 
For the control of grasses and some broadleaf weed species, such as smooth and large crab­
grass, green festal, yellow festal, lovegrass, witchgrass, carpetweed, common chickweed, 
lambsquarters, purslane and Florida pus ley. 10\ Dacthal Granules is recommended at 80-90 
pounds per acre. A slightly higher rate of application (up to 105 pounds per acre) of the 
product may be required for control of bdrnyardgrass, ground cherry, dodder, browntop 
penicum, goosegrass, johnsongrass from seed, and redroot pigweed. For control of nodding 
spurge, spotted spurge or prostrate spurge, apply 105-120 lbs. of lOt Dacthal Granules in 
mid-april or when annual weed seeds, such as crabgrass, germinate. Repeat 3pplication 6-8 
weeks later. A rate of 150 Ibs. per acre is recommended for control of annual bluegrass 
in turf. When lOt Dacthal Granules is used at the recommended rate, up to 3 months weed 
control can be expected. Bermudagrass, johnsongrass, established from rhizomes, nutsedge,

controlled with 10% Dacthal Granules. 
Application should be made to a uniform weed-free soil surface within 2-3 days maximum 
following cultivation to prevent sub-surface germinating weeds from becoming established. 
Disturbing the soil surface following application will reduce effectiveness. Rates of 
application can be reduced by banding. Lawn spreaders should be properly calibrated prior 
to use to deliver 10\ Dacthal Granules at prescribed rate. Settings may vary between 
spreaders because of condition and other factors. 
10\ Dacthal Granules can also be applied by the shaker can method. 
this is to measure off the area to be treated into small plots and 
the prescribed quantity of 10\ Dacthal Granules on this area.

If there is no rai~ within three or four days after 10\ Dacthal Granules application, 
sprinkler irrigatio., (1/2-1 inch of water) should be used for best results. 
Replanting: Replanting crops other than those included on this label in Dacthal treated 
soil within eight months of application may result in crop injury. If replanting is 
required because of an early crop failure, the planting of onions, seeded melons. pota­
toes, tomatoes, eggplants or peppers at this time may be planted following harvest of 
Dacthal treated crop. 
Apy application of Dacthal should be made prior to weed seed germination. 
USB PRECAUTIONS 
Do not feed treated foliage to livestock or graze treated areas. Applied according to 
directions and under conditions favorable to good plant growth, 10\ Dacthal Granules will 
not harm corps for which it is recommended; however. conditions such as high salt concen­
tration, seedling disease, cold weather, deep planting, excessive moisture or dro~ght may 
injure or weaken crops 1I0rmally tolerant to lOt Dacthal Granules thereby increasing the 
possibility of herbicidl' damage. Under any ot- these conditions, one or more of the fol­
lowing may result, delayed crop development, reduced yields or reduced quality. 
TURF AI1D ORIWIBHTALS 
Orna.ental Turf. Apply uniformly to established turfgrass at 100 Ibs. 10\ Dacthal Gra­
nules per acre in the early ipring before crabgrass and other annual grasses and broadleat 
weed seeds germinate. Crabgrass seed germination usually coincides with the time Forsy­
thia blossoms start to fall. One application in early Spring before weed seed germination 
usually provides season long control. In areas whict. commonly experience stands of late­
germinating crabgrass and other annual weedy grasses, a second application at half the 
regular rate can be safely made two months after the first application. To control annual 
bluegrass (Poa annual and other erratic or later germinating grasses and weeds in northern 
states. supplement the early Spring application of lOt Dacthal Granules with an applica­
tion of 150 lbs. 10\ Dacthal Granules in late Summer or early Fall before weed seed ger­
mination. Earlier applications are required in southern United States. Consult Agric~l­
tural Experiment Station or Extension Service weed specialist for date Poa annua seeds 
germinate in your area and make application at least two weeks prior to this date. 
Early Spring application of lOt Dacthal Granules may be made to new turfgrass seedlings 
after the grasses have exhibited a uniform greening and the grass is pref~rably 1-2 inches 
in height. 
Where some Spring seeding is necessary, there shLuld be a delay of approximately 60 days 
after application of 10\ Dacthal Granules. This delay increases the survival of desirable

Riverdale 10\ Dacthal Granules Page 5 
grasses. Fall seeding of permanent grasses may follow a single application made either in 
early Spring up to not less than 60 days of seeding. 10\ Dacthal granules is not recom­
mended for use on putting-greens. 10\ Dacthal is not recommended on bentgrasses when 
mowed at putting-green heights. Do not apply to Dichondra. 
Plower Gardens: Apply after establishment of bed and conditions are favorable for good 
plant growth, or as a supplemental application of 90 lbs. lOt Dacthal Granules per acre. 
Where possible the bed should be established and application made early in the Spring. De­
layed or secondary applications, when needed, can be made at any time provided beds have 
been cultivated and are free of weeds. Weed control up to three months or more may be 
expected following proper application. See list of ornamentals. 
Nursery Stock or Orn ..... ntal Planting.. Apply at lining-out, late Fall or early Spring at 
90 1bs. 10\ Dactha1 Granules per acre. Applications should be made to soil recently cul­
tivated to a uniform texture. These can be made immediatelY,following lining-out of 
stock. With established plantings, application should be made" following proper cultiva­
tion to remove exiting weeds. Where possible this should be done early in the Spring 
Late Summer applications may prove beneficial for control of Fall-germinating weeds, if 
made following cultivation. Weed control up to three months or more may be expected, fol­
lowing proper application. lOt Dactha1 Granules is specifically recommended for weed con­
