Malathion for Control of Black Grass Bug, 1978
Insecticide and Acaricide Tests, 1981Abstract Malathion ULV concentrate was applied at 8, 6 and 3 fluid oz of technical material (91%)/acre to 40 acre plots replicated 4 times, and 2 fluid oz of technical material/acre was applied to a 100 acre plot near Llaves, NM from May 10 through 13, 1978. All plots had been reseeded with Crested Wheatgrass. All dosages except the 8 oz

Herbicide-resistance to mesosulfuron + iodosulfuron in Alopecurus myosuroides (black-grass).
Communications in agricultural and applied biological sciences, 2009A formulated mixture of two sulfonylurea herbicides, mesosulfuron and iodosulfuron, combined with the safener mefenpyr-diethyl ('Atlantis') is being used extensively in Europe and there is concern that resistance will evolve in Alopecurus myosuroides (black-grass).

Education + Training, 1970
Whatever debt the English may owe historically to the Welsh, and whatever the statistics, nowhere is it more obvious than in Glamorgan that the excellence of Welsh education rests in the past. As with Scotland, and even the old LCC, the triumphs of the past have overshadowed the slow progress of the present. True, the search for education remains. True,

Control of Alopecurus myosuroides (black-grass) resistant to mesosulfuron+iodosulfuron.
Communications in agricultural and applied biological sciences, 2010Resistance to the ALS inhibitor mesosulfuron+iodosulfuron ('Atlantis') had been identified in 293 populations of A. myosuroides in the UK by 2008. Two field trials were conducted in winter wheat crops where ALS target site resistance (Pro197Thr) occurred. Mesosulfuron+iodosulfuron (12+2.4 g a.i. ha(-1)) gave 73% - 79% reductions in head numbers in Town

Crossing abilities of ALS target-site resistant black-grass (Alopecurus myosuroides Huds.).
Communications in agricultural and applied biological sciences, 2011Black-grass crossings were conducted outdoor for two successive years in a way to determine the percentage of resistant black-grass that can be engendered in one generation, after the introduction of one target-site resistant individual. After germination, plants were genotyped and couples of resistant and susceptible individuals were formed, then ...

Theoretical and Applied Genetics, 2002
Chloroplastic acetyl CoA-carboxylase (ACCase) is the target of widely used, specific graminicide herbicides: cyclohexanediones (CHDs) and aryloxyphenoxypropionates (APPs). Resistance to these compounds is a worldwide, increasing problem. Population genetic studies aimed at understanding the dynamics of this situation and the diffusion of resistance ...

Crop Protection, 1994
Abstract Herbicide resistance in black-grass (Alopecurus myosuroides) is a continuing problem in England and has also evolved in some other European countries. The UK Weed Resistance Action Group has devised guidelines for the prevention and control of herbicide-resistant black-grass based on recent research studies, which are summarized.

EVOLUTIONS OF A BLACK-GRASS POPULATION SUBMITTED TO DIVERSE CROP SYSTEMS.
Communications in agricultural and applied biological sciences, 2015Black-grass is a common grass weed, widely spread in Northern Europe and also in Belgium. The first case of resistance in Belgium was reported by Eelen et al. (1996). Since then, monitoring showed that resistant black-grass was not confined to restricted areas anymore and that all usually effective modes of action could be subject to resistance issue ...

Herbicide Resistance in the Weed Alopecurus Myosuroides (Black-Grass): The Current Situation
1992Chlorotoluron-resistant Alopecurus myosuroides was first detected in England in 1982 and has now been found on 46 farms in 19 counties. Resistance is mainly associated with winter cereal crops established by non-ploughing cultivation techniques, where herbicides have been applied regularly, on average 1.6 applications per year. The degree of resistance
