Yellow nutsedge (Cyperus esculentus L.) and Johnsongrass (Sorghum halepense (L.) Pers.) are two of the most difficult weeds to control mostly due their asexual reproduction. reproduces through underground tubers rhizomes. In addition, is a problematic weed because its competitive nature C4 carbon fixation pathway metabolism. It typically grows 1.8 2.5 m tall can severely reduce yields in corn, ...

Prickly sida (Sida spinosa), hemp sesbania (Sesbania herbacea), and pitted morningglory (Ipomoea lacunose) are becoming problematic weeds in many crops including corn soybean. Two separate field experiments, under non-crop conditions, were conducted at the Mississippi State University Delta Research Extension Center, Stoneville, MS to evaluate response of these eight selective herbicides three ...

This study evaluated Liberty (glufosinate) and Enlist One (2,4-D choline) at three application timings with various tank mix partners for weed control in fallow. Most herbicides tested controlled 94% or more of volunteer sorghum 17 days after the late postemergence treatments season. Conversely, Palmer amaranth crabgrass was less than 90% most herbicides. However, these species good when Tricor...

This document provides a comprehensive review of information and data relevant to the environmental risk assessment of the protein phosphinothricin-N-acetyl transferase (PAT) produced in genetically engineered (GE) plants by genes isolated from Streptomyces viridochromogenes (pat gene) or Streptomyces hygroscopicus (bar gene) and presents a summary statement about the environmental safety of th...
