The cool weather during spring 2018 delayed planting and was conducive to root and soilborne pathogens. Root diseases, including those caused by Fusarium and Rhizoctonia species were prevalent in many fields, causing damping off, stunting of seedlings, root rot, seedling blight, poor seedling vigor, and poor stand establishment.
Sudden Death Syndrome (SDS) was found in soybean near Sutherland in west central Nebraska last Friday. While uncommon in the area, moist conditions earlier in the year would have been favorable for its development.
Surveys made in 2017 revealed widespread soilborne diseases in many crop hosts and many field locations in the state. This update is provided on four soilborne pathogens: Rhizoctonia, Fusarium, Phytophthora, and Cephalosporium. An article of the 2018 Nebraska Crop Production Clinic Proceedings.
Timely control of volunteer wheat and other weeds is key to managing yield loss risk in your 2018 crop. Yield-limiting risk factors affected by weed control include wheat streak mosaic and other diseases, insects (wheat stem sawfly and disease vectors), moisture loss, and increased weed seed production.
Grain-type field peas are a cool season grain crop grown as an alternative for no-till summer fallow in a semiarid cereal-based cropping systems such as wheat-corn-fallow and/or wheat-fallow. They are typically planted in mid-March and harvested late-July. This article reports on research conducted on seeding practices and offers recommendations for producers on the economically optimal seeding rate, seeding depth, and inoculant to grow field peas in western Nebraska.
