Identification of Efficacious Adjuvants for Sethoxydim and Bentazon

Weed Technology, 1989
Experimental adjuvants were tested to maximize herbicidal activity of sethoxydim on quackgrass and of bentazon on common lambsquarters. Efficacious adjuvants were identified by measuring the14C-herbicide droplet spread and absorption, as influenced by various adjuvants, on the target weed.

Effect of Ammonium Sulfate and Bentazon on Sethoxydim Absorption

Weed Technology, 1989
The effect of ammonium sulfate on absorption of14C-sethoxydim applied alone and with bentazon was studied in large crabgrass. Adding ammonium sulfate to14C-sethoxydim increased14C absorption 6-fold at 0.5 h after application but did not affect the amount of14C absorbed 1 or 4 h after application.

Interaction of Fluometuron and MSMA with Sethoxydim and Fluazifop

Weed Science, 1987
Field experiments were conducted to determine the effects of tank-mixing fluometuron {N,N-dimethyl-N′-[3-(trifluoromethyl)phenyl] urea} or MSMA (monosodium salt of methylarsonic acid) with sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} or the butyl ester of fluazifop {(±)-2-[4-[[5-(trifluoromethyl)-2 ...

Analytical Techniques to Measure Sethoxydim and Breakdown Products

Weed Science, 1986
A method was developed for the quantitative determination of trace levels of the widely used herbicide sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} and its metabolites in an aqueous solution using reversed-phase high-performance liquid chromatography (HPLC).

Sethoxydim Response to Spray Carrier Chemical Properties and Environment

Weed Technology, 1994
Experiments were conducted to determine the influence of spray carrier salts, UV light, and temperature on sethoxydim phytotoxicity to oat or yellow foxtail. Spray solution pH and ions present were both important to sethoxydim phytotoxicity to oat. Sodium and calcium salts were antagonistic to sethoxydim phytotoxicity only when the spray carrier pH ...

Overcoming Antagonistic Effects of Na-Bentazon on Sethoxydim Absorption

Weed Technology, 1993
The influence of adjuvants, inorganic salts, and herbicide formulations on the antagonistic effect of Na-bentazon on sethoxydim absorption was studied in quackgrass. Adjuvant BCH 815 00, at 2.4 L ha−1alone or at 1.2 L ha−1combined with 1.1 kg ha−1of ammonium sulfate, added to the sethoxydim and Na-bentazon spray mixture overcame the antagonism on14C ...

Effects of Various Adjuvants on Sethoxydim Activity

Weed Technology, 1992
Field experiments were conducted at the Lacombe Research Station from 1989 to 1991 to determine the influence of various adjuvants on sethoxydim activity. In all experiments sethoxydim was applied at 100 g ai ha-1to green foxtail, wheat, wild oat, and barley seeded in a canola crop.

Persistence studies with the herbicide sethoxydim in prairie soils

Weed Research, 1983
SummaryThe persistence of [14C]sethoxydim (2‐[1‐(ethoxyimino)butyl]‐5‐[2‐(ethylthio)propyl]‐3‐hydroxy‐2‐cyclohexene‐1‐one) at the 2 μg g−1 level was studied under laboratory conditions in three soils at 20°C and 85% of their field capacity moistures.

Salt and Temperature Effects on Sethoxydim Spray Deposit and Efficacy

Weed Technology, 1999
Certain salts in the spray carrier can antagonize sethoxydim, while other salts overcome the antagonism or increase the herbicide's efficacy. Sethoxydim responses to salts have not been consistent, and the inconsistency is not completely understood. Experiments were conducted in the greenhouse to determine sethoxydim phytotoxicity to oat as influenced ...

Carrier Volume Effects on the Antagonism of Sethoxydim by Bentazon

Weed Science, 1987
The effect of spray carrier volume on the antagonism of sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} by bentazon [3-(1-methylethyl)-(1H)-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide] was investigated under greenhouse and field conditions.
