Penoxsulam is a new post-emergence rice herbicide for applications
in drained and semi-flooded paddies.
It is an acetolactate synthase inhibitor herbicide developed in the
This substance is designed to control existing broadleaf weeds and
similar plants in lawns, rice fields and cereal crops. While
penoxsulam is not effective against most grass species,
it can be used to control a few specific weed grass species.
Penoxsulam was originally designed for use in rice fields and is
capable of killing several pest grasses that prefer wet
We have successfully synthesized standards of the Penoxsulam. This
will be of interest to agrochemical companies and analytical labs.
Simazine is an organic white solid, used as a pre-emergence
herbicide used for control of broad-leaved and grassy weeds on a
variety of deep-rooted crops such as artichokes, asparagus, berry
crops, broad beans, citrus, etc., and on non-crop areas such as
farm ponds and fish hatcheries. Its major use is on corn where it
is often combined with AAtrex. Other herbicides with which simazine
is combined include: paraquat, on apples, peaches; Roundup or Oust
for noncrop use; Surflan on Christmas trees; Dual on corn and
Simazine is an important weed control tool in cherry and in apricot.
A combination of simazine and either oryzalin, norflurazon, or oxyfluorfen showed excellent weed control in sour cherry with no tree injury .
In California approximately 150 pounds of simazine were applied to
200A of cherry and apricot crops in 2004.
For the years 2002–2005, simazine was applied to 13.0% of US cherry
crops . Simazine ranked second among residual herbicides used on cherry, being applied to an average 16288 A. Oxyfluorfen
was the most frequently used residual herbicide, treating an
average of 16.3% of acres.
