Scythe® is a fatty acid based, non-selective, contact herbicide. Formulated as a liquid, Scythe readily mixes with water to be applied as a foliar spray for the control of suppression of annual weeds and grasses, and for top kill of perennial species.
Mode of Action
Scythe kills weeds and grasses fast. When Scythe makes contact
with a living plant, the spray quickly penetrates green plant
tissue, and disrupts normal membrane permeability and cellular
physiology. The disruption of the cell membrane results in cell
leakage and death of all contacted tissues. Results are usually
visible within minutes after treatment. Depending on plant size
and species, some re-growth may occur and require additional treatment.
Soil Activity
Because Scythe is rapidly degraded into the environment, treated
areas can be sown(e.g. to lawn grass) or transplanted into as
soon as desirable levels of weed control are obtained. Scythe
may be applied for post-emergent control of weeds in areas that
have been seeded, or planted with bulbs or other underground propagation
parts, provided that the desirable plants have not yet emerged.
When tank mixed, low rates of Scythe substantially increase the rate of glyphosate absorption by the green tissue. Scythe has the unique property of accelerating burn-down of treated foliage, without reducing the systemic activity of glyphosate. Herbicidal effects on plants treated with this combination usually become evident within a few hours after application, compared with several days for plants treated with glyphosate alone the accelerated death of treated plants is due to both the rapid herbicidal activity of Scythe and to increase uptake of glyphosate stimulated by Scythe. This increase in absorption improves consistency across diverse environment conditions.
