I’m currently doing a project on resistant ryegrass as part of my BASIS qualification, I’m doing a case study on the farm I manage (currently waiting on results for resistance type) What I’m after is some more data to compare the farm here with others with a Ryegrass problem to see if there’s any similarities. So if anyone is kind enough (particularly if you have resistant ryegrass) could you answer some or all of the following questions (truthfully!!) either on the thread or PM me, it would be most appreciated, it’s all anonymous (unless you post the answers below!). 1. Where is the farm located? 2. What size is the farm? 3. Farm enterprises? 4. Crops grown in your rotation? 5. Soil type? 6. Do you have grass leys in your arable rotation? 7. What sort of cultivations/drilling are carried out? 8. Do you have known resistant blackgrass? 9. Do you have known resistant ryegrass? If ‘yes’ go to question 10, if ‘no’ go to question 15 10. Which chemicals/products is the Ryegrass resistant to? 11. Have you had the Ryegrass resistance tested? If so what were the results? 12. What non-chemical methods have you implemented to try and control the Ryegrass and have they been successful? (eg: Stale seed bed/ploughing etc) 13. Do you spread muck with a potential Ryegrass seed return? 14. What is your opinion on the cause of the resistance? 15. Does a contractor carry out the spraying duties on the farm? 16. What water volume rate is applied when spraying your post-emergence herbicide? 17. What speed are you travelling at whilst spraying your post-emergence herbicides at? 18. Do you use resistance strategies when making decisions on herbicide applications if so which? (eg: using chemicals with different modes of action/avoiding sequential applications of the same herbicide) As a discussion point, has anyone got on top a resistant ryegrass problem? Does anyone find it has limited germination in the spring?
