The wet spring has caused soybean root rot problems in North Dakota. Damping off and root rots can be caused by many different pathogens; Pythium species, Phytophthora sojae, Fusarium species and Rhizoctonia solani. Unfortunately, it can be very difficult to determine which pathogen is causing the primary disease. In many cases, it is likely that multiple pathogens are acting synergistically to cause the damping off.
Saline soils have salt levels high enough that crop yields begin to suffer or cropping is impractical. Several factors contribute to the development of saline soils. A high water table is a prime requirement. Recognizing how and why salts accumulate is the first step in farming profitably on land interspersed with saline soils. Preventing further encroachment of salinity and addressing remediation strategies are other steps.
Palmer amaranth can produce millions of seeds per plant and grow baseball bat-sized stems that can stop combines. It has forced radical changes in weed control because of its relentless ability to reproduce and spread at astounding rates. The latest information shows that glyphosate–resistant Palmer amaranth is now present in every Midwest and Plains state except Minnesota and North Dakota. Palmer amaranth was chosen as North Dakota weed of the year as a proactive approach to increase awareness of its extreme noxious and pernicious capability, to aid in identification and to encourage land owners to keep a vigilant watch and kill all plants that may grow.
It is that time of year when NDSU Research Extension Centers across the state hold their annual field days. Field days are a chance for researchers and Extension faculty to share information on topics such as: ■ New crop varieties ■ Better production methods ■ Weed control ■ Soil health ■ Grazing intensity ■ Cattle nutrition and genetic disorders ■ Irrigation ■ Manure management ■ Precision agriculture ■ Biofuel development
Broadleaf crop plants have emerged or are just emerging, so this is the time to count the plants and calculate what percent of the seeds actually came up. The target live seed (those seeds that can germinate) planted and the seeds actually making it into an established plant can differ by 10 to 15 percent.
Many species of tall deciduous trees are available for conservation and urban plantings. The ND Tree Selector is an online tool that helps users choose tree and shrub species based on a variety of characteristics. Are you looking for something that is fast growing or a tree that is long-lived? Perhaps a species with pretty flowers? The ND Tree Selector can help you find species to consider for your next planting.
Each season brings new challenges and pest problems in crop production. One way to stay informed and effectively manage any problem is to sign up for the weekly “Crop and Pest Report.” Each issue from May to September contains valuable information about insect and disease problems, pest alerts, integrated pest management strategies, pesticide updates, agronomy and fertility issues, horticulture problems, reports from the NDSU Plant Diagnostic Laboratory and a weather outlook. Also, please "like" the "Crop and Pest Report" on Facebook.
Weeds not only detract from the aesthetic quality of an otherwise well-maintained turfgrass, they are extremely worthy competitors with lawn grasses for the basic factors of growth – space, light, water, and nutrients. The first step in controlling weeds is to correctly identify them to implement a successful control program.
With all the information available today, how do we separate fact from fiction? What are the clues to reliable health information in today’s fast-paced world? “Finding the Truth II: Are Popular Nutrition and Health Information Sources Reliable?” explores a few popular nutrition information sources and ways to determine if the information is reliable.
