Anthracnose Leaf Blight, Top Die-Back and Stalk Rot in Corn
Anthracnose Leaf Blight, Top Die-Back and Stalk Rot in Corn
Anthracnose in corn has a leaf blight phase and a stalk rot phase. Top-die back is a significant symptom of the stalk rot phase. The leaf blight is an indicator that the pathogen is present in the field, but does not confirm that the stalk rot phase will be an issue. The stalk rot phase is of greater concern than the leaf blight phase in terms of potential yield loss. The majority of lost yield potential from anthracnose can be attributed to premature plant death that interrupts filling of the grain, and stalk breakage and lodging that causes harvest loss and complications. Early identification of anthracnose can help prioritize fields for harvest, which can help minimize loss at harvest.

DEKALB® Brand Genuity™ Roundup Ready 2 Yield™ Soybeans
In summer 2009 there was a lot of excitement with the introduction of Monsanto’s newest soybean technology, Genuity™ Roundup Ready 2 Yield™. Four years of U.S. field trials and field trials in Eastern Canada verified the yield benefit of Genuity™ Roundup Ready 2 Yield™ soybeans and provided the backdrop for the launch of this new technology.
Tillers in Corn, Separate the Fact from Fiction
Tillers in Corn, Separate the Fact from Fiction
Tillers are vegetative or reproductive shoots that grow from the base of grass plants. Corn is a highly specialized grass plant. While tillers are an essential part of wheat, barley, and oat production, they are perceived to be far less desirable in corn. They are commonly referred to as “suckers,” because of the old wives tale that they “suck” the nutrients from the main stem. Research from the University of Illinois has shown that this is not the case. Many agronomists agree that the overall effect of tillers is usually neutral. There may be some benefit to tillers if corn is produced for silage because more dry matter is produced per unit area.
Scouting for Western Bean Cutworm Egg Masses
Scouting for Western Bean Cutworm Egg Masses
All late tasseling fields should be checked now… WHAT TO SCOUT: prioritize scouting of late planted fields or other fields that have not tasseled or have tasseled later than the majority of fields in your area. WBC are showing a very strong preference for pre-tasseled fields, so any pre-tassel fields will have many more egg masses laid in them. This doesn’t mean you won’t get any eggs laid in a field that is in tassel, but the majority of eggs will be laid in pre-tassel fields (if available) so start there. They also seem to be showing some preference for fields with sandy soils. Make sure you scout at least 20 plants in each of 5 different areas of the field. The more plants you check the better.

Growing Knowledge - March 2010
Sustainable agriculture is a concept that many influential and knowledgeable people define in different ways. When we engaged in discussing the concept of sustainable agriculture with groups of diverse backgrounds, (employees, customers, policy makers, global experts on the topic), it was very evident that it is a complex topic. What was clear in those conversations was the point that several challenges are real; one billion people go hungry every day, the world’s population will increase by 50% by 2050, rising income in developing nations will demand more diverse and protein rich diets in the future, and water shortages and climate change will impact agriculture production in the future.
Leaf Yellowing in Soybeans
Leaf Yellowing in Soybeans
Yellowing of leaf tissue occurs in the development of soybean plants. Nitrogen deficiency, manganese deficiency, potassium deficiency, soybean cyst nematodes, and yellow flash herbicide application have been shown to have a role in soybean leaves turning yellow.
