Semi‐tilling maintains the arthropod food web structure but decreases biological pest control in olive groves

open access: yesAnnals of Applied Biology, Volume 187, Issue 3, Page 345-355, November 2025.
Semi‐tillage, a widely used agricultural method to improve water availability and minimise soil erosion in crops, may compromise pest control in olive groves. Stable isotopes (N15 and C13) analysis showed an effect of semi‐tillage in the composition of the basal resources of potential natural enemies in the three olive grove strata: These changes may ...

Horseweed (Conyza canadensis) Control in Full-Season No-Till Soybeans (Glycine max)

open access: yes, 1990
Cyanazine and 2,4-D were the most effective herbicides for horseweed control before establishing full-season no-till soybeans. Paraquat plus 2,4-D was less effective than 2,4-D alone but superior to paraquat alone.

Biology and Management of Horseweed and Hairy Fleabane in California [PDF]

open access: yes, 2008
Horseweed and hairy fleabane are showing increased resistance to chemical controls, including glyphosate. By learning about their biology and other control alternatives, you can do a better job of keeping on top of this pest ...

Similarity in Persistence Traits Is Important for CoExistence With Perennial Invasive Asclepias syriaca but Not Annual Invasive Conyza canadensis

open access: yesJournal of Vegetation Science, Volume 36, Issue 6, November/December 2025.
We tested two alternative hypotheses regarding the co‐occurrence of selected invasive species with other species based on functional traits: (1) if limiting similarity is the dominant assembly process; the less similar species are more likely to associate with the targeted invasive species, or (2) if environmental filtering is more important; then more

Biology and management of select Indiana horseweed biotypes

open access: yes, 2010
Horseweed (Conyza canadensis), a member of the Asteraceae family, is an annual plant that can behave as either a winter annual or summer annual. It predominantly self-pollinates and can produce in excess of 1,000,000 wind-blown seeds.

Herbicidas alternativos para controle de biótipos de Conyza bonariensis e C. canadensis resistentes ao glyphosate Alternative herbicides to control glyphosate-resistant biotypes of Conyza bonariensis and C. canadensis

open access: yesPlanta Daninha, 2010
Após sucessivos anos, aplicações do herbicida glyphosate em pomares de citros no Estado de São Paulo selecionaram biótipos resistentes de Conyza bonariensis e C. canadensis.

Comparing the impacts of patch‐burn grazing on vegetation in two northern tallgrass prairies

open access: yesConservation Science and Practice, Volume 7, Issue 10, October 2025.
We evaluated two of the earliest and largest patch‐burn grazing projects in the eastern tallgrass prairie of Minnesota, an ecosystem that has undergone extensive fragmentation and invasion by non‐native species. Our results in grazed and ungrazed plots varied with differences in stocking rate and fire frequency.
