Identification and Management of Palmer Amaranth in South Dakota
Guide for the identification and management of Palmer Amaranth in South Dakota

Managing Weed Seed in 2020
Producers need to plan in advance on how to deal with bare fields that contain an overabundance of weeds. Weeds in these fields have deposited significant amount of seeds on the soil surface, which can easily germinate when adequate moisture and temperature are available.

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.

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.

Utilize a Fungicide For Crown Rust Prevention in Oats
If you are growing oats this year for grain, be sure to scout and plan a fungicide application to protect the oats from crown rust.
