The use of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile)
to control broadleaf weeds in cereal crops has become widespread.
This herbicide has not always performed satisfactorily for reasons
which were not clearly evident.
The effects of temperature, light and humidity on the herbicidal
activity of bromoxynil on coast fiddleneck, Amsinckia intermedia,
were studied. Fiddleneck...
Several studies were conducted to determine if a more consistent
predictor of phytotoxicity to winter oats could be obtained with a
surfactant-herbicide ratio or a per-unit-volume concentration of surfactant,
independent of volume. The herbicides tested were 2,2-dichloropropionic acid (dalapon), 1,1'-dimethyl-4, 4'-bipyridinium
(paraquat), and 3-tert-butyl-5-chloro-6-methyluracil (terbacil) with
the nonionic surfactant X-77...
