Postemergence herbicide application season is already upon us in much of Iowa, but with the delayed crop planting in some areas, it may extend through much of the month of June. Herbicide application timing should always focus on the sizes of weeds targeted but remember that many products use...

The trapping season for true armyworm (TAW) and black cutworm (BCW) has come to an end. We appreciate our cooperators for tirelessly checking traps over the last two months and reporting their captures so we can provide the most accurate scouting information for these pests. To recap, we had 44...

This year’s Weed Science Field Day will be held on Thursday, July 14 at the Iowa State University Curtiss Farm, Ames, IA.

Although the 2022 cold and wet spring has significantly delayed corn and soybean planting in Iowa, we are still on track to demonstrate corn and soybean research plots...

Weather conditions were quite favorable this past week allowing Iowa farmers 5.4 days for fieldwork across Iowa allowing for significant planting progress across nearly all of Iowa.  With that said, there are still isolated pockets where soils remain too wet to allow for fieldwork.  Frost...

When a pesticide application moves beyond the application site to a place it’s not wanted – known as pesticide drift – it can cause damage to acreages, gardens, and landscape plants. Pesticide drift can occur virtually anywhere – in rural areas, towns, and cities.

Farmers finally caught a break last week and were able to make a lot of planting progress across most of the state. Some areas that did not miss the rains last week had more limited progress made with getting the crop in the ground. The earlier planted crops and even some of the crops put in...

Western and northern corn rootworms are serious corn pests in Iowa and the Corn Belt. These pests readily adapt to management tactics, especially in continuous corn production. The larvae consume corn roots, reducing nutrient and water uptake and causing stalk lodging. The adults may also feed...

The planting is slow in 2022 – according to last Monday’s USDA Crop Progress Report corn planting was at 14% and soybean planting was at 7% complete. This is nearly two weeks behind normal. This week’s warm temperatures have driven up soil temperatures but wet soil conditions are still the...

While not much planting progress was made last week (again), the warmer and drier weather this week should provide more favorable conditions for fieldwork and planting. Some of the hot topics over the last week across the state included concerns about cover crop termination, seeding forages yet...

This spring's weather has resulted in an unusually slow start to the growing season, especially when compared with the past two years. In springs like these, field operations are condensed and there may be temptation to skip some of the field preparation to get acres planted in a timely manner....
