Cover crop dos and don’ts

first_imgShare Facebook Twitter Google + LinkedIn Pinterest I have had several questions through the winter on cover crop removal. I have experience with Austrian winter pea and annual ryegrass in some of my cover crop work. I like Austrian pea, it is easy — just apply your normal burndown of glyphosate, atrazine and favorite pre-emergent grass product for corn. Annual ryegrass on the other hand was difficult to manage. In reading the literature on control, it seems others have difficulty, too.A new publication on Cover Crop Do’s and Don’ts (WS-53-W) from Purdue Extension came out last year in June too late for 2016, but plenty early for this year. Their suggestions fit with my concerns too. So what are some of their do’s and don’ts? Weed management• Do terminate cover crops before planting.• Don’t use annual ryegrass.• Don’t reduce herbicide use.• Don’t rely on cover crops for universal weed suppression. Insect Management• Do be committed to scouting.• Don’t treat unnecessarily.• Don’t plant immediately after killing a cover crop.• Do wait 10 to 14 days after a cover crop has died. Disease Management• Don’t rely on cover crops solely to reduce diseases.• Do use multiple management practices.For a more complete look at cover crop termination see the Purdue Publication on Successful Cover Crop Termination with Herbicides bulletin, WS-50-W: read more
