author keywords: herbicide-resistant crops
topics (OpenAlex): Weed Control and Herbicide Applications; Plant tissue culture and regeneration; Pesticide and Herbicide Environmental Studies
TL;DR: Field studies evaluated crop tolerance, weed control, and yield with CGA-362622 alone and in combination with various weed management systems in transgenic and nontransgenic cotton systems in North Carolina in 1998 and 1999. (via Semantic Scholar)

Bromoxynil, Prometryn, Pyrithiobac, and MSMA Weed Management Systems for Bromoxynil-Resistant Cotton (Gossypium hirsutum)1

CORBETT, J. E. R. R. Y. L., ASKEW, S. H. A. W. N. D., PORTERFIELD, D. U. N. K., & WILCUT, J. O. H. N. W. (2002, October 1). Weed Technology.

author keywords: crop injury; herbicide-resistant cotton; Brachiaria platyphylla; BRAPP
topics (OpenAlex): Weed Control and Herbicide Applications; Research in Cotton Cultivation; Allelopathy and phytotoxic interactions
TL;DR: The LAYBY treatment of prometryn plus MSMA frequently improved late-season control of entireleaf morningglory, large crabgrass, prickly sida, and sicklepod, and the LAYBy treatment ofprometrynplus MSMA increased cotton yields in 13 out of 16 comparisons. (via Semantic Scholar)

author keywords: antagonism; growth analysis; orthogonal contrasts
topics (OpenAlex): Weed Control and Herbicide Applications; Plant and fungal interactions; Nematode management and characterization studies
TL;DR: Field and greenhouse experiments were conducted to evaluate clethodim, CGA-362622, mixtures thereof, and sequential treatments for control of broadleaf signalgrass, fall panicum, goosegrass, and large crabgrass and the effectiveness of the graminicide was decreased. (via Semantic Scholar)

Weed management with CGA-362622, fluometuron, and prometryn in cotton

Porterfield, D., Wilcut, J. W., & Askew, S. D. (2002, September 1). Weed Science.

By: D. Porterfield n, J. Wilcut n & S. Askew n

topics (OpenAlex): Weed Control and Herbicide Applications; Agronomic Practices and Intercropping Systems; Pesticide and Herbicide Environmental Studies
TL;DR: An experiment conducted at five locations in North Carolina during 1998 and 1999 evaluated weed management systems in cotton with CGA-362622 and pyrithiobac and improved the control of all weed species and increased lint yield compared with the systems that did not use prometryn plus MSMA LAYBY when PRE or POST herbicides were used.
