Common Rust in Corn

Written by Pioneer Agronomy Sciences

Common Rust is a fungal disease, that is spread by windblown spores.  Yield losses may result from poorly filled kernels and lodging-induced harvest losses.  This article discusses what to look for, how to manage it, and how to identify hybrids with built-in resistance.

Northern Corn Leaf Blight

Written by Pioneer Agronomy Sciences

Hot, humid weather conditions make for ideal conditions for Northern Corn leaf blight (NCLB).  While infection can occur during any growth stage, plants are more susceptible after pollination.  Yield losses are most severe when NCLB infects plants early and can result in yield loss.

Anthracnose of Soybean

Written by Pioneer Agronomy Sciences

Anthracnose is a fungal disease of soybean that occurs worldwide wherever soybean is grown.  Dark brown lesions develop, the stem may collapse, and seedlings may die under severe infection. Favored by warm, humid, and wet environments, Anthracnose can cause severe yield reductions under these conditions.

Early-Season Weed Control

Written by Pioneer Sciences Researchers

Early weed control helps protect and maintain the maximum yield potential of the crop.  Weeds can reduce yield in corn as early as the V2 stage.  For soybeans, control is necessary from week four until canopy closure. Learn about why early control is necessary, the critical periods and what to do about.

Delayed Corn Planting Considerations

Written by Pioneer Agronomy Sciences

When rainfall significantly delays field and planting operations, switching to early maturity hybrids may be considered to ensure timely crop maturation. Results indicate that growers should plant full season hybrids until approximately May 26.   Switching to an early maturity hybrid prior to this point most likely will not be beneficial and may result in reduced profitability.
