Most organic vegetable growers rely heavily on intensive soil
tillage or plastic films to control weeds within crop rows. Recent
technological advances have improved post-planting precision
tillage options for intra-row weed management in organic vegetables
(Rafaelli et al., 2010, 2011), but the efficacy of tillage often
depends on ideal soil conditions and is time-sensitive (Gunsolus,
1990). Similarly, recent development of new plastic and biodegradable
mulches (Kasirajan and Ngouajio, 2012) has improved
weed control in vegetable crops, but weeds can still emerge
through planting holes or tears in plastic mulch (Schonbeck, 1999;
Miles et al., 2012). Despite their effectiveness, tillage and mulching
may not provide season-long weed suppression when used alone.
