GENERAL INFORMATION
Metsulfuron EUP is recommended for post-emergence use for control or suppression of certain broadleaf weeds in wheat (spring and durum), barley, established creeping red fescue (seed or forage), orchard grass and crested and intermediate wheat grass (seed or forage) in the Prairie Provinces and the Peace River Region of British Columbia (soil pH of 7.9 or lower).
Metsulfuron Methyl EUP is a 60% active ingredient herbicide formulated as a dry flowable granule. Metsulfuron Methyl EUP is to be mixed in water with a recommended surfactant and applied as a uniform broadcast spray. It is noncorrosive, nonflammable, nonvolatile and does not freeze. Wheat, barley or creeping red fescue may be grazed by or fed to livestock anytime after treatment.
Prior to using Metsulfuron Methyl EUP careful consideration should be given to crop rotation plans. Crops other than those listed in the "Minimum Crop Rotation Guidelines" section can be very sensitive to low concentrations of Metsulfuron Methyl EUP in the soil. Refer to the "Minimum Crop Rotation Guidelines" section of this label to plan Metsulfuron Methyl EUP use and crop rotations.
Rainfall, soil temperature and soil pH are important factors affecting Metsulfuron Methyl EUP breakdown in the soil. Metsulfuron Methyl EUP breakdown is more rapid under conditions of moist soil, warm soil temperatures and low soil pH. The breakdown process is slower under conditions of dry soil, cool soil temperatures and high soil pH.
Metsulfuron Methyl EUP must be applied with a recommended surfactant early postemergence to the main flush of actively growing broadleaf weeds. Warm, moist growing conditions promote active weed growth and enhance the activity of Metsulfuron EUP by allowing maximum foliar uptake and contact activity. If cold, dry conditions prevail, delay treatment until active weed growth resumes. Weeds hardened off by cold weather or drought stress may not be adequately controlled or suppressed and regrowth may occur. Metsulfuron Methyl EUP may only be applied with ground spray equipment. For best results, ensure good spray coverage of target species.
Metsulfuron Methyl EUP is an ALS inhibitor herbicide and thus, rapidly inhibits the growth of susceptible species. However, typical symptoms (discoloration) of dying weeds may not be noticeable for 1 to 3 weeks after application depending upon growing conditions and weed susceptibility. Degree of control and duration of effect depend on the rate used, sensitivity and size of target species, as well as growing conditions, soil moisture, soil temperature and soil pH and spray coverage.
In some cases, tank mixing a pest control product with another pest control product or a fertilizer can result in biological effects that could include, but are not limited to: reduced pest efficacy or increased host crop injury. The user should contact E.I du Pont Canada Company at 1-800-667-3925 for information before mixing any pesticide or fertilizer that is not specifically recommended on this label. The user assumes the risk of losses that result from the use of tank mixes that do not appear on this label or that are not specifically recommended by E.I du Pont Canada Company.
