Temperature Inversions
It is never recommended to spray a pesticide when a temperature inversion exists, and many labels provide guidelines to follow in order to avoid applications during one. This blog will discuss what temperature inversions are, why they can be dangerous for pesticide applications, and how to identify when temperature inversions are happening.
In order to keep up with any changes and updates on pesticide uses and restrictions from year to year, it’s important to thoroughly read the label before any applications are made, even if the same product was used the previous year. If nothing else, it helps to refresh our memory on the particulars of specific products that are applied to ensure optimum pest control and environmental protection. Since 2017, growers have been able to utilize dicamba products labeled for over-the-top application in soybean.
Join the ISU Weed Science Program at the 2019 Herbicide Research and Demonstration Program Field Day on Thursday, June 27!
Iowa State University Extension and Outreach published the Field Crop Scouting book as an online learning tool for crop scouts and other ag professionals in Iowa. This interactive textbook allows individuals to acquire knowledge about multiple crop scouting topics to help create stronger crop production systems in Iowa. These include:
The 2013 Herbicide Guide for Iowa Corn and Soybean Production (WC 94) can now be accessed from the Iowa State University Weed Science web page. The publication provides an update of new herbicide products as well as an herbicide effectiveness chart for herbicides used in soybean and corn. Herbicide site of action and injury symptoms are described and information about herbicide group numbers is included. A list of prepackage mixtures of herbicides is included. The current herbicide resistant weed situation in Iowa is described and a discussion about Palmer amaranth is pr
Despite the cancellation of the Iowa State University Weed Science field day originally scheduled for June 26, there is still an opportunity to review the weed management demonstrations and research at the ISU Curtiss Farm on South State Street in Ames.
Since planting and herbicide applications are still underway, particularly for soybeans, it is suggested that a good opportunity to see the weed science research exists after the first week in July.
