Wk. Vencill et al., EFFECT OF MON-12037 ON PURPLE (CYPERUS-ROTUNDUS) AND YELLOW (CYPERUS-ESCULENTUS) NUTSEDGE, Weed technology, 9(1), 1995, pp. 148-152
Greenhouse studies were conducted to determine the response of purple
and yellow nutsedge to selective soil placement of 5 cm of soil treate
d with MON-12037 above and/or below the nutsedge tubers. MON-12037 at
53 g/ai ha applied as a foliar, soil, or foliar + soil application als
o were evaluated. MON-12037 placement above, below, or above + below t
he nutsedge tuber decreased shoot number, shoot dry weight, shoot regr
owth dry weight, and root-tuber dry weight production in both species,
30 and 60 d after treatment. MON-12037 applied as a foliar, soil, and
foliar + soil treatment was effective in reducing purple nutsedge sho
ot regrowth dry weight to less than 5% of the non-treated control. Yel
low nutsedge shoot regrowth dry weight from the foliar + soil and soil
-only applications was less than 1% of the non-treated control.
