GENERAL INfORMATION: 
DYNAMYTE 2.5 Dinitro Weed Killer when used with the proper amount 
of water controls ~~st annual weeds, grasses and top growth of 
herbaceouc perennial weeds and grasses. It may also be uued for 
pre-harvest application (harvest aid) on potatoes and various 
seed crops .. uch a .. lellWlle ... and uoybean .. to rCIIIUve cxccuuivc full"l~c. 
DYNAHYTE 2.5 Dinitro Weed Killer ~y also be used for weed control 
in such non-crop areas as airfields, walks, fence lines, roadSides, 
driveways, storage yards, pole yards, tank farms, railroad yards 
ar.d switches as well as around industrial esteblis~ents. 
The lower application rates will satisfactorily control s~ll annual 
grasses and weeds (crabgrass, foxtail, barnyardgrass, pigweed, 
la~bsquarter, ~ustard and sorrel) while the higher application rates 
will be required to control coarse and resistant grasses and weeds 
(wildoats, chickweed, ~yweed, ~llow, pineapple weed, wild carrot 
and fennels). 
DYNAMYTE 2.5 Dinitro Weed Killer is a contact herbicide to control 
annual weed pests but retreatment will be required for perennials 
and any regrowth that should occur. Use enough spray ~terial to 
wet all vegetation to be controlled. DYN~~TE 2.5 Dinitro Weed 
Killer is a contact herbicide which inhibits plant reypiration and 
coagulates plant proteins. It will not translocate. 
MIXING INSTRUCTIONS 
Mix at the rate of 1 gallon of DYNAKYTE 2.5 Herbicide in 50 - 60 
gallons of water. fill spray tank half full with water. With 
spray tank agitator running add DYNAMYTE 2.5 Herbicide to the tank • 
Add the remaining required amount of water and ~x thoroughly. 
The Spl""y ~x is now ready to apply. 
APPLICATION DIRECTIONS: 
Apply DYNAKYTE 2.5 Herbicide ~xture in a sufficient volume to 
thoroughly wet all of the weed and grass foliage to the "rull off" 
point. This will usually require fro~ 250 to 400 gallons of .. pray 
per treated acre. 
GENERAL WEED CONTROL: Use one (1) gallon of DYNAMYTE 2.5 Herbicide 
in 50 - 60 gallons of water. Spray weed growth thoroughly. For 
aerial application use 2 to 4 quarts of DYNAMYTE 2.5 Herbicide in 
4 to 15 gallons of water.

PRE-EMERGENCE WEED CONTROL: DYNAMYTE 2.5 Herbicide may be used to 
kill tiny weeds that eJIlerge before certain crops. When pl'actical, 
fitting (disking) the land several days before planting will result 
in more weeds being up at the time of spraying. For use on land 
planted to the large seeded crops, beans, corn, curcuruits. potatoe~. 
and gladiolus. Spray at least one d .. y before first emergence of 
the crop using l~ quarts of DYNAMYTE 2.5 Herbicide per acre. Mix 
thl" ","ount with :)0 1;11110ns of wate." amI ""ply as a fille bP."ay 
to insure wetting of the weeds. 
GRAPES AND BUSH FRUITS: Apply DYNAMYTE 2.5 Herbicide spray when 
weeds are growing well, but before thp.v are 6 inches high. On Grapes, 
application may be made up to 3 or 4 wr.eka after bloom. For use in 
the spring before bloom or in the fall after harvest use 2 to 3 quarts 
of DYNAMYTE 2.5 Herbicide in 100 gallons of water. For treatment during 
bloom and up to 3 or 4 weeks after bloom use no more than 2 quarts of 
DYNAMYTE 2.5 Herbicide per 100 gallons of spray. Use up to 150 gallons 
per acre to insure good weed coverage making sure to apply as a directed 
spray. Avoid spraying grape foliage, blooms or fruiting clusters. 
It nmy be desirable to limit treatment to a 1 or 2 foot band directly 
undp.r crellis where weed problems are most severe and mechanical 
cultivation is difficult. For such band treatment, reduce application 
rate proportionately. Repeat if regrowth appears, but limit appli­
cations to 2 during a single season. On Bush Fruit (blackberries, 
blueberries, currents, gooseberries and raspberries) use 2 to 3 quarts 
of DYNAMYTE 2.5 Herbicide in 100 gallons of water. Apply 125 to 
150 gallons per acre after harvest or in spring before bloom. Use 
a directed spray, do not treat young canes desired for permanent 
plants. Make 1 or 2 repeat applications as needed. DYNAMYTE 2.5 
Herbicide can be used in combination with certain other herbicides. 
ALFALFA: Apply to established stands during dormant season to control 
winter annuals or apply immediately following first cutting, but 
before regrowth starts for control of dodder and sUllllIlcr annual,,_ Nix 
2 to 3 quarts DYN~~TE 2.5 Herbicide in 100 gallons of water. Spray 
mixture thoroughly wetting all weed foliage, using approximately 
100 gallons per acre. Use the high spray rate where grassy weeds 
are the major problem. 
NOTE: DO NOT FEED TREATED FOLIAGE TO LIVESTOCK OR GRAZE TREATED AREAS. 
SEED CROPS (Plfalfa, Trefoil, Peas and Soybeans): Pre-harvest aid to 
facilitate seed crop harvesting: Apply 3 to 6 days before harvest. 
For air application, use 2 to 3 quarts DYNAMYTE 2.5 Herbicide in 4 to 
10 gallons of water per acre. For ground application, use 2 to 3 qua~ts 
DYNA}~TE 2.5 Herbicide per acre.

A maximum of 2 quarts per acre may be applied on Peas. Thls may hI! 
mixed with 8 to 15 gallons of water for low-vol~e sprays or with 
25 to 40 gallons of water for high volume sprays. The higher rates 
and volumes are suggested for use during cool, cloudy weather and 
under heavy foliage conditions. 
NOTE: DO NOT FEED TREATED FOLIAGE TO LIVESTOCK OR GRAZE TREATED AREAS •

harvc~L. !lpruy volwu4! anll COllccntrat!on~ per acre urc UClccullncJ 
by the variety and vigor of the vines, degree of kill desired and 
weather conditions at the time of applicatiun. Use the higher 
rates during cool, cloudy weather or under heavy foliage conditions. 
Low volume a.r or ground sprayers use 2 to 3 quarts of DYN~~TE 2.5 
Herbicide in 5 to 10 gallons of water per sere. For medium volume 
sprayers, use 2 to 4 quarts of DYNAHYTE 2.5 Herbicide per acre in 
25 to 40 gallons of water, depending on density of vine growth. 
Use nozzles that g~ve coverage to all parts of the plant. 
NOTE: IIrownin.; of th" vascular rin!; of potato tubers sometimes 
occur after the use 01 ville killer.. Do not spray exposed tubers. 
Do not graz~ tr~t~tJ drt=4~. 
GROUND COVER (llirectd "pray): For Citrus, Date and Nut Groves 
including almonds, fjlu~rt~. pecalls and walnuts; Deciduous Fruit 
Orchards, includin~ apples, pears, peaches, cherries, apricots, plums 
and prunes; Drainage DjtchLanks; mix 2 to 3 quarts of DYNAMYTE 2.5 
Herbicide in enoup,h water to make 100 gallons of spray. Apply as a 
coarse spray and th0roul;hly cover all .eed foliage. On crop areas, 
DO NOT APPLY more than 100 gallons of the completed spray per acre. 
Destroy any contaminate'i fruit. Do not spray young tree stock as 
girding may occur. Avoid getting any spray material on the fruit. 
Do not contaminate irrigation or domestic .aters. Do not allow live­
Slack to graze treated areas. 
DOWNY MILDEW ON HOPS (Control uf Basil Spike Phase): Control is 
obtained by killing diseased basel parts of the vines, this aUs 
in coltrolling further fungus spread. Use 2 quarts DYNAMYTE 2.5 
Herbicide in enough water to make 100 gallons of finished spray. 
Make the first application on the ground and the lower 2 feet of the 
vines, making sure the plant has reached the height of 8 feet. 
Use 50 gallons per acre, repeat as needed, but DO NOT use more than 
4 applications per season. When the vines have reach~d 3/4 of the 
trellis height the lower (base) 4 feet of vine should be sprayed. 
This will materially control weeds in trellis areas. The application 
rate will have to be increased proportionately to obtain control. 
NOTE: Do not spray entirl! vine.
