![]() Glyphosate is another broad-spectrum herbicide and is a herbicide option for burndown in no-till corn. There are many options for fall herbicide applications, such as Harmony Extra, a broad-spectrum herbicide. Some winter annual weeds are easier to manage in the fall rather than waiting until the spring. There is a temptation, when applying herbicides, to wait until all the weeds have emerged, but this is counterproductive. Certain herbicides can be applied in nitrogen carriers, but it’s important to get the timing right. When spring is approaching, for example, populations of winter annual weeds become prevalent, thereby competing with wheat and barley. Weed Management in Agronomic Crops: Corn, Soybean, and WheatĬorn, soybean, and wheat have specific weed management issues to contend with. Mid-season weed control issues also include herbicide drift. The effectiveness of any weed control method depends on a number of different things, such as the time of the year, unstable weather conditions, crop injury, and tank-mixing. The Agronomy Weed and Pest Management Tour is one way you can find out about the new herbicide products.Ĭonservation tillage systems are another way of managing weeds that uses cultural, mechanical, and chemical control tactics. The use of herbicides is just one method, with new herbicide products entering the market every year. Weed management plays an important part in agronomic field diagnostics. Penn State Extension’s Introduction to Weeds and Herbicides covers the important issues surrounding weeds and their control. Not only are there different types of weeds, but there are also many different methods for controlling them. Understanding these life cycles, for example, helps agronomic crop producers decide whether they can control annual and perennial weeds after silage harvest or in fallow areas. Weeds can be broken down into annuals, biennials, and perennials, each of which has its own life cycle. Weed Management Best PracticesĪgronomic crop weed management requires year-round vigilance and control. On this page, find recommendations for managing weeds in agronomic crops such as corn, grain, soybeans, small grains, and forages.
