Herbicide Orange Monitoring Program. Addendum 1
1985Abstract : In April 1970, the Secretaries of Agriculture; Health, Education, and Welfare; and the Interior jointly announced the suspension of certain used of 2, 4,5-trichlorophenoxyacetic acid (2,4,5-T). This suspension resulted from published studies indicating that 2,4,5-T was a teratogen.

Herbicide Programs for Managing Creeping Rivergrass (Echinochloa Polystachya) in Rice
Weed Technology, 2007A study was established to evaluate herbicides registered for barnyardgrass control in rice for activity on creeping rivergrass. Treatments included 208 g ai/ha cyhalofop early POST (EPOST) followed by (fb) 315 g/ha cyhalofop late POST (LPOST), 22 g ai/ha bispyribac EPOST fb 22 g/ha bispyribac LPOST, 66 g ai/ha fenoxaprop EPOST fb 86 g/ha fenoxaprop ...

Comparison of Herbicide Programs for Weed Control in Glyphosate-Resistant Alfalfa
Weed Technology, 2010The objective of this experiment was to determine the effectiveness and crop safety of glyphosate vs. alternative herbicides for weed control in glyphosate-resistant alfalfa. Glyphosate-resistant alfalfa was established at two sites in Pennsylvania in 2004 and in 2005, and herbicides were applied either PRE or POST for weed control. Data were collected

Herbicide programs for the termination of grass and broadleaf cover crop species
Weed Technology, 2019AbstractThe use of cover crops in soybean production systems has increased in recent years. There are many questions surrounding cover crops—specifically about benefits to crop production and most effective herbicides for spring termination. No studies evaluating cover crop termination have been conducted across a wide geographic area, to our knowledge.

Imazethapyr plus Residual Herbicide Programs for Imidazolinone-Resistant Rice
Weed Technology, 2012Field studies were conducted in 2008 and 2009 near Crowley, LA to evaluate the addition of a herbicide with soil-residual activity in mixture with imazethapyr applied very early POST followed by an application of imazethapyr or imazamox 2 wk after the initial application. Weeds evaluated included red rice, barnyardgrass, and alligatorweed. Weed control

Weed Technology, 2020
AbstractControl of waterhemp is becoming more difficult in Ontario because biotypes have evolved resistance to four herbicide sites of action (SOA), including groups 2, 5, 9, and 14. The objective of this study was to compare PRE, POST, and PRE followed by (fb) POST herbicide programs for their effect on control, density, and biomass of multiple ...

Evaluation of Thiencarbazone-methyl– and Isoxaflutole-Based Herbicide Programs in Corn
Weed Technology, 2012Field studies were conducted in Louisiana and Mississippi in 2009 and 2010 to evaluate PRE herbicide treatments containing isoxaflutole or a prepackaged mixture of thiencarbazone-methyl : isoxaflutole (TCM : isoxaflutole) for weed control in corn. PRE treatments included the premix of TCM : isoxaflutole alone (30 : 80 g ai ha−1) and with atrazine (1 ...

Weeds – A System for Developing a Computer-Based Herbicide Recommendation Program
Weed Technology, 1990A rapid increase in the number of herbicides and herbicide mixtures registered for use in row crops has made herbicide selection difficult. WEEDS is a computer program that enables a weed management expert to build a list of recommended herbicides or herbicide mixtures based upon weed species, soil texture, and soil organic matter content.

The Acetochlor Registration Partnership Surface Water Monitoring Program for Four Corn Herbicides
Journal of Environmental Quality, 2005ABSTRACTA surface drinking water monitoring program for four corn (Zea mays L.) herbicides was conducted during 1995–2001. Stratified random sampling was used to select 175 community water systems (CWSs) within a 12‐state area, with an emphasis on the most vulnerable sites, based on corn intensity and watershed size.
