The latest scouting reports

May 23, 2018

This week I will go over the latest scouting reports from our area. It has felt like summer for the past several days with warm weather and pop-up thunderstorms. Many individuals have been spraying, spreading manure, tilling, and planting for the last two weeks. Many growers are done with corn and finishing up planting beans. The USDA reported that 72 percent of Nebraska’s corn was planted and that 26 percent had emerged.

While out scouting corn and beans, I have seen many summer annuals beginning to germinate and gain size. Common lambsquarter, marestail, kochia, and red root pigweed were seen this week. These weeds are still in the seedling stage or juvenile, so this is the time to knock these weeds back to ensure control throughout the summer. It is recommended to check your fields before spraying. Knowing the type and size of your weeds will drive your spraying choices. Always try to mix your modes of action when determining your tank mix of herbicides. This will help to control your weeds and fight building resistance to certain herbicides. Overall, the corn was between VE to V1 and our beans are between VE to VC.

Our cover crops, wheat, and pastures continue to accumulate biomass. Many of our small grains and wheat fields are at the boot stage. There are several alfalfa fields that are close to being ready for the first cutting. To ensure a high quality forage crop, be sure to watch your alfalfa and check the weather forecast for the best day to cut. Remember, with warm days alfalfa matures quickly making the quality decline. Within some alfalfa fields I have identified alfalfa weevil, but none of the populations were of concern. If you are concerned about pests within your forage crops be sure to scout and sweep your fields. Utilizing a sweep net is a great way to check for insects in forage crops. If you are interested in getting your field swept and would like training on how to properly use the sweep net, please let me know. There is a sweep net available for use at the extension office.

For more detailed information about scouting and herbicides see the 2018 Guide for Weed, Disease, and Insect Management in Nebraska. This guide is a great resource and is available at your local extension office. Also visit CropWatch at UNL extension to read up to date cropping reports from specialist and other educators.
