Apparent Bow Saw 600 (Metsulfuron)

Bow Saw Metsulfuron Methyl 600 WG Herbicide is used for the control of certain broadleaf weeds in winter cereal crops and broadleaf weeds and brush species (woody weeds) in pastures, rights of way, commercial and industrial areas.

Apply early post crop emergence (3 leaf to before booting) when weeds are small (i.e. no greater than 5 cm in height or diameter) and actively growing.

Best weed control is obtained when rainfall wets the soil to a depth of 5 to 7.5 cm within 4 weeks of application. Where treatment is delayed or where weeds are not actively growing due to adverse conditions, results may be slow to appear and weeds may be only stunted or suppressed.

After application for post-emergent weed control, Apparent Bow Saw 600 Herbicide will remain in the soil for a period of time.

The persistence of Apparent Bow Saw 600 Herbicide in the soil is dependent on various environmental conditions, e.g. soil pH, temperature, soil moisture and organic matter. Wet, warm, acid soils high in organic matter favour breakdown of Apparent Bow Saw 600 Herbicide in the soil.

It should be noted that Apparent Bow Saw 600 Herbicide does NOT provide soil residual control. Crops other than wheat, barley, triticale and cereal rye may be extremely sensitive to low concentrations of Apparent Bow Saw 600 Herbicide residues in the sprayer or in the soil. See “Sprayer Clean-up” and “Crop Rotation Recommendations.”
