Alternative Pasture Weed Control
The term ‘weed’ can be broadly applied to any plant that is undesirable at any given time and place based on certain criteria. It is important to understand that the word ‘weed’ has become a general term with no universal definition, and many plants are considered to be weeds, depending on location.
Perennial Solutions for Alkali Areas
Reclaiming marginal lands, especially those considered saline or sodic can be very challenging and may take many years to accomplish. The key to turning around salt or alkali areas in your fields, begins with getting a living root established in the affected area.
Managing Weeds While Transforming Marginal Land Into Perennial Forages Production
There are currently millions acres across South Dakota impacted by saline and sodic conditions. Research has shown that salt-tolerant perennial grasses are a possible way to bring land back into production.
Check Fields for Palmer Amaranth
Palmer amaranth, is an aggressive weed from the pigweed family, which has been reported with increasing frequency in recent years around Central South Dakota.
Herbicide Residual Effects on Cover Crops after Corn Silage
Fact sheet about herbicide residual effect on cover crops after corn silage.
“Snirt” and How To Minimize It
Blowing soils, dust storms and “snirt” (snow with dirt on it) are frequent challenges during dry, windy winters. Learn some soil health principles to limit erosion and minimize snirt on field edges this planting season.
Spring and Winter Camelina in South Dakota
In the semi-arid, western portion of South Dakota, camelina has potential value as a fall-seeded cover crop, providing flexibility in crop rotations for improving soil health.
Bacterial Stem Rot, Sclerotinia Basal Rot and Sunflower Rust Developing in Sunflower
Sunflower scouted this week in Brookings and Kingsbury counties were found with bacterial stem rot, Sclerotinia basal rot and sunflower rust. This area has had plenty of moisture, which favors several diseases to develop in sunflower.
Bacterial Blight Developing in Oats
Oats scouted in a few fields in the Eastern and South Central parts of the state were found with bacterial blight developing on the lower leaves. Plants infected have leaves with water-soaked brown longitudinal lesions in the top-half of the leaf. Severe symptoms can lead to premature leaf death.
2018 Field Plot Summaries for Oat and Sorghum Foliar Disease Management Trials
An oat crown rust integrated management trial and a sorghum foliar fungicide trials were conducted to determine the efficacy of fungicides to manage crown rust and fungal diseases in oat and sorghum respectively. Crown rust is one of the most devastating diseases of oat in the state. Stragego fungicide was applied at three different timings to determine the most effective timing for crown rust management. For sorghum, the study investigated the efficacy of two different rates of Nexicor for managing sorghum foliar diseases. The oat field experiment was maintained at Northeast Research Farm (NERF), Southeast research farm (SERF) and Volga research farm. The sorghum experiment was at Volga.
