Members of the umbelliferae broad-leaved weed family must be identified and dealt with specifically in the spring, as autumn herbicide strategies do not target them. These include wild carrot, fool's parsley, shepherd's needle, corn parsley and bur chervil. Bur chervil, in particular, has been reported to be an increasing problem across Shropshire and Herefordshire, but is often incorrectly identified as wild carrot. [Extracted from the article]

The article reports on knowledge transfer initiative which is helping farmers tackle damaging agronomic threat of herbicide resistant weeds. Topics discussed include deep pool of information to draw from published by commercial agriculture firm AHDB Cereals & Oilseeds, approach of grain industry to clear messaging on weed control, and resistance of ryegrass and wild raddish.

The article presents information on James Alexander, farmer in Great Britain who is planning to increase yields by cutting his diesel bill by switching to direct drilling across his organic cropping. Topics discussed include having a combination of cover crops, mechanical weeders and high seed rates; focusing on weed control; and using red clover and rye grass for blackgrass control.

The article discusses farmers' methods for combating grass weeds with pre-emergence and post-emergence herbicide, and cites two examples: of farmer Richard Gill combating ryegrass, and farmers Andrew and Tom Ownsworth combating blackgrass. Topics discussed include management practices for blackgrass and ryegrass by the growers; views of Ben Coombs, herbicides campaign manager, on yield-sapping effects; and effect of coal mining on grass growing soil.

Discusses the necessity of controlling the ryegrass weed. Consequences of not controlling ryegrass; Information on an herbicide product used for ryegrass weed control.

The article focuses on glyphosate resistance found by the author in his ryegrass plant in western Australia and the need to take action against the resistance of ryegrass for herbicides. Topics discussed include tillering ryegrass found by the author in a crop of barley even after spraying Roundup; resistance management in Western Australia that found glyphosate resistance in ryegrass from truck delivering wheat and need for residual herbicides and mechanical weed seed capture to control weeds.

The article presents information on Axial wild oat and ryegrass herbicide from Syngenta. Rod Burke of Syngenta comments on herbicides used for control of wild oat and ryegrass. The use of the product has benefits for growers of wheat and barley. The herbicide will have a barley blackgrass control recommendation.
