Biology and management of cut-leaved Teasel (Dipsacus laciniatus L.) in central Missouri
(University of Missouri--Columbia, 2006)
locations by measuring plant dry weight and leaf area. Herbicide efficacy experiments were conducted with four modes of action: amino acid biosynthesis inhibitors, growth regulators, acetolactate synthase (ALS) inhibitors, and cell membrane disrupters. Total...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
and germination of poison hemlock seed were measured. Dry biomass of poison hemlock was measured through time in the early spring in relation to plant density. Herbicide efficacy experiments were conducted in the spring using amino acid biosynthesis inhibitors...
Integrated management of the invasive weed, cut-leaved teasel (Dipsacus laciniatus L.) along a Missouri highways
(University of Missouri--Columbia, 2008)
Cut-leaved leaved teasel is an invasive, exotic, and noxious weed in Missouri. Biennial plant infest roadsides and undisturbed areas. Studies regarding seed biology, detection, and control measures were conducted to improve teasel management along a...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
bluegrass (hereafter referred to as CCMO1) in Columbia, Missouri survived an application of glyphosate following more than 10 years of continuous applications. Research was conducted in vitro to identify the extent of glyphosate-resistance in CCMO1...
Allelopathic effects and removal of overseeded ryegrass on bermudagrass
(University of Missouri--Columbia, 2010)
Allelopathy is a complex phenomenon among plants that involves the production of defensive chemicals that influence the growth and survival of adjacent plants. Plants like perennial ryegrass become suspect when bermudagrass ...
