Solubility in water: Completely miscible; mixes readily with water. Flammability: Nonflammable, formulation is a water based salt. Freezing point: Freezes at -20F; returns to liquid state upon thawing. Although heated storage is not required, storage above 10F is suggested. Shelf life: Formulation is very stable. Will last at least 4 years under normal warehouse conditions. pH: 4.5. Active Ingredient: Isopropylamine salt of glyphosate.* Contains 41% active ingredient by weight. Contains 4 Ib/CJ.S. gallon or 480 gm/liter. Inert Ingredients: 59% by weight, includes a surfactant to aid adher ence and absorption by plant foliage. TOXICOLOGICAL PROPERTIES Fish and Wildlife: Investigations conducted on bobwhite quail, mal lard ducks, honeybees, rainbow trout, bluegills and other species of fish showed these species have extremely high tolerance. Acute Toxicity: Oral LD> -- 4900 mg/kg (rats). Skin absorption MLD.io >7940 mg/kg (rabbits). Glyphosate Is the common name for N-(phosphonomethyl) glycine Subacute Toxicity: Results of subacute toxicity testing have shown no toxicological properties which would limit labeled uses of Roundup herbicide. Irritation: Mild skin irritant; causes eye irritation. Toxicity Category: Category II pesticide. Label carries WARNING! statement based only on eye irritation as required by the Environmental Protection Agency. Symptoms of Poisoning: No unique symptoms. First Aid and Antidotes: Avoid contact with eyes, skin and clothing be cause of possible irritation. In case of eye contact, flush immediately for 15 minutes with plenty of water. If irritation persists, call a physician. Flush skin with water. There is no specific antidote for this formulation and in light of its low acute oral toxicity, none should be necessary. HERBICIDAL PROPERTIES AND GSE General: Roundup is a broad-spectrum, foliar applied her bicide that is considered relatively non-selective. Controls most species dependent on stage of growth and herbicide rate. Very effective on pe rennial, annual and biennial species of grasses, sedges, and broadleaved weeds. Mode of Action: Absorbed through foliage and translocated throughout the plant. Visible effects normally occur in 2 to 4 days on annual species, and 7 to 10 days on perennial species. Translocation to 0615327 TOWOLDMONOQ39321 underground propagules of perennial speciesprevents regrowth and results in their destruction. Soil Activity: Roundup has no residual soil activity and is herbicidaily effective only when applied to leaf and green stem tissue. The active ingredient is adsorbed strongly by soil particles, thereby pre venting root uptake, leaching, and herbicidal activity in the soil. Volatility: Does not volatilize or move as a vapor to harm adjacent vegetation. Breakdown: Microbiological degradation is the major cause of decomposition. In the soil, the active ingredient is not taken up by plants, is essentially immobile and relatively nonpersistent. Rate of breakdown de pends on microfloral population and type; nor mally the half-life is less than 60 days and soil' residues are near or below \0% of that applied within a growing season. Application Method: Applied in water as a postemergence spray to actively growing foliage of vegetation to be con trolled. Selectivity can be achieved by directional application, by shielding desirable vegetation, or by different physiological stages of treated vegetation. - Application Timing: Effective on annuals at all active growth stages. On perennials, best control is usually achieved at or beyond bud or boot stage, or when applied late in the growing season. Application Sites: Labeled for use in many cropping systems and noncropland sites. Mixing: . Since Roundup herbicide is water soluble, it read ily mixes with water. To minimize foaming from the surfactant included in the formulation, add Roundup near the end of the filling process and minimize agitation. Acceptable Equipment: Roundup may be mixed and applied in stainless steel, aluminum, fiberglass, plastic, and plastic lined containers. Roundup is compatible with nearly all plastics and elastomers used as sprayer components including nylon, polyethylene, polypropylene, acetal, polyester, polystyrene, polyurethane, polyvinyl chloride, silicone, Teflon,* Viton,* EPDM, Buna N and SBR. Do not use galvanized or unlined steel (except stainless) containers. Some types of nitrile hose may be come stiff after prolonged use. USE PRECAUTIONS Avoid Drift: If fine spray particles are allowed to drift onto desirable plants during application; they may be injured or killed. Avoid combinations of wind, spray pressure, and nozzle types which are more likely to produce fine particles and cause drift. Use Clean Water. Dirt or mud in water can adsorb Roundup and cause reduced performance. Avoid Rainfall: Rain occurring within six hours of application may wash some Roundup off treated plants and re duce effectiveness. If heavy rain occurs within two hours after application, repeat treatments may be required. Treat Active Growth: Reduced results may occur if treated vegetation is covered with dust, if it is under drought stress, or if it is damaged by diseases, insects, mechanical injury, or previous chemical treatments. Use Proper Equipment: Make sure equipment is clean and properly calib rated. Do not mix, store, or apply Roundup or spray solutions of Roundup in galvanized or un lined steel (except stainless) containers. Avoid Contact: Roundup herbicide is a mild skin irritant and causes eye irritation. Therefore, contact with eyes, skin, or clothing should be avoided.
