Armyworm moths prefer to lay their eggs on dense grassy vegetation (e.g., wheat, grass hay, and grass cover crops). Larval development should now have advanced to the point that fields should be assessed for feeding damage.
For growers who had issues with rain or armyworm issues in October, Oklahoma State University Extension shares some management adjustments that could help late-planted winter wheat still succeed.
Location, location, location. That’s honestly one of the reasons I’ve been successful in no-till over the years. I’m not talking about the land, though — it’s the people I’ve been fortunate enough to be surrounded by.
Michigan State University Extension recommends scouting fields that had a cover crop or a lot of weed growth prior to planting, and to consider whether an insecticide spray in wheat is necessary.
Ohio State University Extension says the recent rainy, cool weather is ideal for slugs, with no-till fields with high residue at a higher risk of slug feeding.
Black cutworms lay eggs on grassy weeds or cover crops, low-growing winter annuals and no-till crop residue, while armyworms are attracted to weedy corn fields, cover crops, grassy alfalfa stands and wheat fields.
We know there are many benefits that make no-till worthwhile — less cost for fuel and labor, improved soil structure and health, better water infiltration and holding capacity — the list goes on.
Our 23rd annual National No-Tillage Conference has come and gone, and as a second-time attendee I’m still overwhelmed by the amount of no-till research, insights and information that were presented last week.
A 3-year research study conducted by five U.S. universities and the USDA found that fall armyworms in the southeastern U.S. are developing resistance to genetically modified crops.
