does it make it through a graminicide or through a kerb applicationwhen the land is in a break ? or is the field/fields in continous cereals ?It quite possibly is resistant as accidental extra dose does not even touch it , But what to do if it is? Glyphosate kills it but it just comes back next year.Although I have not ploughed this field since the last centuary I did plough it last year,and paid particular attention to do the job properly, but it seems to be back anyhow.
Do you feel your claydon approach has altered your ryegrass position at all?A resistance test will save you a lot of wasted herbicides. ADAS is the first port of call. They will advise on how to take the samples. Test your water that you use for spraying if it's mains or bore water too. DeSangosse can help you with that.
I have a couple of ryegrass fields that stubbornly refused to clean up. Lots of dead plants but it germinates when it feels like and gets very waxy very quickly so needs decent adjuvants in the tank with contact herbicides. Spring cropping will help but you need to consider pre harvest desiccation to help kill what's there.
The drill is useless for weed control. Pre drilling cultivations are only by choice and the drill disturbs soil, breaking dormancy of weeds (not just ryegrass). What is getting weeds under control is the system - specifically more spring crops. I was using pre drilling glyphosate before, even pre ploughing in spring, so little change there.Do you feel your claydon approach has altered your ryegrass position at all?
