Biological Information and Remarks
Soil-applied preemergence herbicide for control of
annual grass weeds and many broadleaf weeds in
12-(a-naphthoxy)- N,N -
certain fruit and nut crops, many vegetable crops,
and ornamental crops. It is rapidly absorbed by roots
and translocated upwards throughout the plant. It
inhibits the development and growth of roots of
annual grass plants. It resists leaching in soil, and is
slowly broken down by soil microbes. It photode-
composes about 50 percent in 4 days on the soil
surface. When incorporated in soil the half-life is 8
to 12 weeks.
A soil-applied, preemergence herbicide for control of
3,5-dinitro- N4,N4 -
annual grasses and some broadleaf weeds in soy-
beans, nonbearing trees, vineyards, ornamental trees,
shrubs, flowers and noncropland areas. It is safe to
use around guard rails, fence lines, parking lots, and
other structures adjacent to grass turf. Can be
advantageously combined with paraquat or gly-
phosate, and used as a directed spray for such areas.
It does not volatilize from soil surfaces. Oryzalin
leaches to a limited extent. It is degraded microbially
in the soil. It usually does not persist for more than
