Guidelines for minimising the risk of glyphosate resistance development published by the Weed Resistance Action Group (WRAG) are just what UK growers and agronomists need to safeguard the single most vital weapon in their grass weed control armoury. As such, these guidelines should form the essential basis for all glyphosate use from now on.
Move as little soil as possible, give yourself enough time and use it to greatest effect. These are the three keys to the best, most consistent stale seedbed control of annual grass weeds ahead of drilling identified by independent tillage specialist, Steve Townsend.
A special on-line resource has been launched to provide arable managers across the country with a structured approach to regaining control over their most damaging grassweeds based on the best available soil and crop management intelligence.
Do not expect the levels of performance you have been used to from many glyphosates this summer following the withdrawal of European approval for ethoxylated tallow amine (ETA) formulations, growers have been warned.
Soil compaction costs the UK around £400-500 million every year, cutting wheat yields by 10-15%, increasing tillage energy, time and costs by up to 300% and reducing soil infiltration to almost zero, significantly increasing run-off and flooding.
Appropriate soil management can play a major part in controlling your black-grass before it controls you, growers and agronomists were advised at a national Soil & Water Management Centre improvement event in Lincolnshire.
It is a known fact that the Ministry of Agriculture and Rural Development has withdrawn all glyphosate-based plant protection products containing polyethoxylated tallow amine as a formulation component.
Cultivation immediately after harvesting has become standard practice for growers wanting the best control of problem grassweeds ahead of winter cereal drilling. But it’s about the worst thing they can do after oilseed rape if they also want to deal with the volunteers that can be so problematic in arable rotations.
Herbicide resistance is a very real threat to our ability to effectively control weeds in amenity situations and groundsmen need to take steps to avoid it, warns Monsanto.
Amenity managers and contractors should plan weed control operations carefully in catchy spring weather, warns Monsanto, manufacturer of glyphosate herbicide Roundup ProVantage.
Spraying-off patches of cereals badly-infested with grassweeds this season can be highly cost-effective in preventing disastrous levels of weed seed return, according to leading agronomy advisers. But only if it is done at the right time and with sufficient care.
Grazing livestock producers should be re-seeding 5-10% of their grassland area each year on a carefully-planned basis for the greatest productivity and profitability. They should to do so in programmes that combine the most effective new sward establishment with the least time out of production. And they should look beyond ryegrasses alone to other species in general and hybrid festuloliums in particular for the most palatable and robust seed mixtures.

Maize growers should apply the stale seedbed approach that has proved so successful in controlling problem weeds ahead of autumn cereals to get their crops off to the best, weed-free start this season, advises a leading weed management specialist.
Ecoplug Max is a patented tree stump control application method. Each plug contains 300mg of granular glyphosate which is released inside the tree stump ensuring all the active ingredient is carefully targeted where it is needed.
More care and less speed in stubble glyphosate spraying are critical to making the most of its increasingly vital role in arable grass weed control this autumn, insist leading crop management experts. Published by CPM 8/8/2016
Getting the timing right is key to maximising efficacy as is the correct approach to spraying. Check out the essentials of best practice.
Tips on making the most of stubble management
Considerations for, and timing of, OSR desiccation in an unpredictable climate
Currently there are no known cases of glyphosate resistance in the UK; to help ensure this remains the case the Weed Resistance Action Group have issued guidelines for minimizing the risk of it developing.
