Creator:: Burr, Ronald J.
Abstract:: Previous research has shown that activated carbon is effective in inactivating certain herbicides applied as a preemergence treatment. Studies were conducted in the greenhouse to determine the influence of various factors on the ability of activated carbon to inactivate herbicides applied after carbon application. Field studies were conducted to determine...

Creator:: Kitagawa, Yukio
Abstract:: The persistence of DCPA, trifluralin, diphenamid, diuron, and prometryne was studied in three soils which were located at the Kula, Poamoho, and Waimanalo Experiment Stations. The order of decreasing persistency was diuron, prometryne, trifluralin, DCPA, and diphenamid. Diuron and prometryne activities were recorded for at least six months and diuron...

Abstract:: 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...

Abstract:: 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...
