The persistence of five herbicides in Hawaiian soil

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...

Masters Thesis
The influence of various surfactant-herbicide ratios in three volumes of water on the toxicity of dalapon, paraquat, and terbacil to winter oats (Avena sativa L.)

Creator:

Migchelbrink, Kenneth John

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...

Masters Thesis
Factors influencing the effectiveness of activated carbon used to protect newly-seeded grasses from herbicides

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...
