EFFECTS OF ANTHROPOGENIC SELECTION PRESSURE ON THE EVOLUTION OF A COMMON AGRICULTURAL WEED: DOES ADAPTATION COME WITH A DETECTABLE COST? A STUDY OF GLYPHOSATE-RESISTANT (GR) AND -SUSCEPTIBLE (GS) BIOTYPES OF Conyza canadensis
… weeds in the landscape. Biotypes of GR <italic>Conyza canadensis</italic> were first observed in Delaware, USA, in 2000. Since the first documentation of GR <italic>C. canadensis</italic>, there have been many instances of independent evolution of GR <italic>C. canadensis</italic> biotypes. The …

Rapeseed (Brassica napus L.) Termination and Integration of Halauxifen into Virginia Cotton (Gossypium hirsutum L.) Production
… marketed for preplant burndown horseweed (Conyza canadensis L.) control. Previous research indicates that halauxifen effectively controls glyphosate-resistant horseweed. However, little is known about control of other common winter annual weeds by halauxifen. Results indicate halauxifen has …

Herbicide combinations for establishing no-till soybeans (Glycine max) with an emphasis on the use of chlorimuron
… the most effective herbicides for horseweed (Conyza canadensis (L.)Cronq.) control prior to establishing full-season no-till soybeans (Glycine max (L.)Merr.). In greenhouse experiments, emergence of tobacco (Nicotiana tabacum L.) seedlings was severely inhibited by all chlorimuron-containing …

Evaluation of herbicides for no-till corn establishment
… perennial broadleaf weeds, including horseweed (Conyza canadensis), buckhorn plantain (Plantago lanceolata), field bindweed (Convolvulus arvensis), curly dock (Rumex crispus) and wild mustard (Sinapis arvensis). All four non-selective herbicides provided good overall weed control. The addition of …

The Role Of Soil Microorganisms In The Resistance Of Giant Ragweed, Horseweed, And Common Lambsquarters To Glyphosate
… giant ragweed (Ambrosia trifida L.), horseweed [(Conyza canadensis (L.) Cronq.], and common lambsquarters (Chenopodium album L.). Through a series of greenhouse and lab experiments we determined that root colonization by soil microorganisms increased the activity of glyphosate in …

Field, greenhouse, and laboratory studies on the efficacy and action of the herbicides SC-0051 and SC-0774
… ragweed (Ambrosia artemisiifolia L.) horseweed (Conyza canadensis (L.) Cronq.), common chickweed (Stellaria media (L.) Vill. and was safe to corn. SC-0051 did not control smooth pigweed (Amaranthus hybridus L.) or giant foxtail (Setaria faberi Herrm.). SC-0774 effectively controlled the rye …

THE INFLUENCE OF CARRIER WATER QUALITY, COAPPLIED FOLIAR FERTILIZER, AND WATER CONDITIONING ADJUVANT ON HERBICIDE EFFICACY
… giant ragweed (Ambrosia trifida L.), horseweed [(Conyza canadensis (L.) Cronq.], Palmer amaranth (Amaranthus palmeri S. Wats.), and pitted morningglory (Ipomoea lacunosa L.). When considering spray solution temperature, premixed dicamba plus glyphosate efficacy was reduced at 5 C compared with 22 …

Conyza bonariensis glyphosate tolerance as affected by origin temperature and growth stage
… in vineyards. Resistance to glyphosate in Conyza bonariensis (L.) Cronquist (flax-leaf fleabane) was reported in 2003 in the Breede Valley, Western Cape. Glyphosate resistant Conyza canadensis (horseweed fleabane) reportedly becomes sensitive at low temperatures (below 12 oC). If the …
