 Wild Oats
Family PoaceaeAvena fatua
Most wild oats
germinate and emerge in early to mid-spring. Cool, moist conditions
promote maximum emergence, so crops that are seeded early are
usually the most heavily infested. Fall or early spring applications
of nitrogen fertilizer stimulate germination. Growth of roots and
shoot of wild oats is slow for the first two weeks, but increases
quickly from then on. Most wild oats tiller within a month of
emergence. |
