Peanut Response to Carfentrazone-ethyl and Pyraflufen-ethyl Applied Postemergence1

Eurasian Watermilfoil and Parrotfeather Control Using Carfentrazone-ethyl

Two invasive weed species, Eurasian watermilfoil ( Myriophyllum spicatum L.) and parrotfeather [ Myriophyllum aquaticum (Vell.) Verdc.], were grown in outdoor mesocosms to determine the efficacy of carfentrazone-ethyl (a,2-dichloro-5[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]-4-fluorobenzenepropanoic acid, ethyl ester), alone and in combination with 2,4-D, a herbicide ...

Broadleaf Weed Control With Carfentrazone-Ethyl Tank Mixtures in Rice

NOTES Combinations of diquat and carfentrazone- ethyl for control of floating aquatic plants

Flowering rush (Butomus umbellatus l.) is a rapidly spreading invasive aquatic plant in the northern United states. Introduced from eurasia, it grows as an emergent plant along shorelines and as a submersed plant in deeper water of lakes and rivers. Because submersed flowering rush grows in fluctuating water levels, management of this plant has been inconsistent and unpredictable. Two small-sca...

Fate and kinetics of carfentrazone-ethyl herbicide in California, USA, flooded rice fields.

Little is known of the environmental fate of the aryltriazolinone herbicide carfentrazone-ethyl (compound I). Rice field applications of Shark 40D commercial formulation to duplicate 5.7 m2 rings (119 g a.i./ha) and 464 m2 commercial basins (224 g a.i./ha) produced pseudo-first-order half-lives (t1/2) of 6.5 to 11.1 h in water and 37.9 to 174 h in sediment. The rapid dissipation from water was ...
