Studies were conducted to determine the site of DCPA toxicity
on annual ryegrass. This was done by means of a technique which
used pyrex tubing and a vapor barrier to separate exposure of coleoptile
and roots of emerging grass seedlings to various concentrations of DCPA. Coleoptiles that emerged through treated...
Studies were conducted to determine the site of 2-chloro
2', 6'-diethyl-N-(methoxymethyl) acetanilide (CP 50144) toxicity on
barnyardgrass (Echinocloa crusgalli (L.) (Beauv.). This was done
by means of a technique which used separate layers of treated soil
to expose differentially the roots and/or the shoots of barnyardgrass
seedlings. Coleoptiles that emerged...
The purpose of this study was to evaluate the activity of Sindone (isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone) under field conditions and to gain information regarding the rate of detoxification of Sindone in soil. A series of trials were established in sugar beet fields in California, Oregon, and Washington. Sindone...
