Private Pesticide Applicator Certification Options

Nearly every South Dakota farmer who applies pesticide must be certified as a private applicator.  Certification for private applications must be renewed every 5 years, with expiration dates at the end of the calendar year.  So, if you haven’t checked your applicator certification, now is the time to check and see if you need to be recertified this spring.  Based on the database provided by the South Dakota Department of Agriculture, all individuals needing recertification for 2012 should also receive a postcard from SDSU Extension stating that it is time to renew.

Soybean Varieties With Rag1 Gene Resistance to Soybean Aphid

Since its first detection in the U.S. over a decade ago, soybean aphid continues to be a yield limiting threat to soybean production in South Dakota.   Aphids can be managed effectively with insecticides through field-scouting and the use of economic thresholds.  An exciting new option for the management of soybean aphids is soybean varieties with bred-in resistance.  These resistant varieties provide new ammunition against this yield-robbing pest.

Herbicide Tolerance Traits: South Dakota Soybean Checkoff Research

Herbicide tolerance traits remain a hot topic of discussion when discussing weed control. LibertyLink® soybeans, dicamba resistant, GAT (glyphosate and ALS tolerant) and other herbicide tolerant soybeans are in the process of being released and marketed. Information is needed to determine whether these new technologies are economical, and if so, how they may best benefit the soybean grower. This article, and others in a series entitled South Dakota Soybean Checkoff Research, will identify and briefly describe some of the research projects funded by checkoff dollars that are conducted by South Dakota State University.

Soybean Aphid Resistance: South Dakota Soybean Checkoff Research

The goal of this project involves identifying and isolating genes, or germplasm, from cultivated and wild soybean that can be used to improve yield, seed quality, pest resistance and energy, nutrient and water use efficiency in soybean plants. This article, and others in a series entitled South Dakota Soybean Checkoff Research, will identify and briefly describe some of the research projects funded by checkoff dollars that are conducted by South Dakota State University.

Stress Tolerance: South Dakota Soybean Checkoff Research

Soybean growers are investing in a wide array of research projects that focus on soybean production and developing new soybean uses. Dollars are obtained at the first point of sale for state boards, regional organizations, such as the South Dakota Soybean Research and Promotion Council, and the United Soybean Board to invest in research and promotion programs. The United Soybean Board (USB) is a volunteer group of producers who administer checkoff dollars invested in soybean research and market development at the national level.  The checkoff dollars used for the research are obtained from soybean producers. This article, and others in a series entitled South Dakota Soybean Checkoff Research, will identify and briefly describe some of the research projects funded by checkoff dollars that are conducted by South Dakota State University.
