A strategy of chemical control of Apera spica-venti L. resistant to sulfonylureas traced on the molecular level

Journal of Plant Protection Research, 2017
Three populations of silky bent grass (Apera spica-venti L.) were tested – one that is susceptible and two that are resistant to sulfonylureas. This study assessed the efficacy of control by different herbicides in a pot experiment and estimated the ...

Evaluation of method performance and matrix effect for 57 commonly used herbicides in some vegetable families using LC-MS/MS determination

Cogent Food & Agriculture, 2020
A modified QuEChERS method was employed with LC-MS/MS to evaluate the matrix effects of 12 different vegetables matrices in 57 globally used herbicides. The average recoveries of pesticides at different concentrations varied between 70 and 120%.

Metabolic resistance to pre-emergence herbicides in grasses

Julius-Kühn-Archiv, 2020
Black-grass (Alopecurus myosuroides Huds.) and rye-grass (Lolium spp) are very competitive grass weeds. During the last decades, they have evolved resistance to post-emergence herbicides, in particular ACCase- and ALS- inhibitors.

Effectiveness of flufenacet in controlling resistant black-grass (Alopecurus myosuroides Huds.) – comparison of glasshouse and field trial results

Julius-Kühn-Archiv, 2012
In the last years in practice, soil acting herbicides have become the backbone for the control of heavy infestations of grass weed populations. The known unsteady efficacy of HRAC group K1, K3 and N herbicides is controversially discussed and became ...

Impact of Panicle Cutting and Chaff Milling on the Panicle and Seed Density of Three Grass Weeds and Grain Yield of Winter Wheat

Weed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT The grass species Alopecurus myosuroides Huds., Lolium multiflorum Lam. and Bromus sterilis L. are abundant and dominant weeds in European winter wheat fields. They cause significant yield losses and impede grain harvest. Many populations of these grass weeds are resistant to one or more herbicide modes of action in Europe.
