Dicamba tolerant soybeans, marketed under the trade name Roundup Ready 2 Xtend Soybeans are again available to Maryland growers for the 2018 growing season. This line of soybeans combines previous Roundup Ready technology with tolerance to the herbicide dicamba. While this new dicamba tolerance may be useful in combatting certain tough-to-control weeds including marestail and palmer amaranth, use caution when applying dicamba. Applications of dicamba may cause problems due to the sensitivity of certain crops to the herbicide. Exposure can occur due to drift, volatility, or a non-target application. This report provides recommendations for using new dicamba-tolerant technologies.
2014 marked the expiration of Monsanto’s patent on the first generation Round-up Ready technology. But, this expiration does not mean that farmers using seed from first generation Roundup Ready technology will be able to save harvested seed for planting a subsequent crop. Many seed companies utilizing this technology may consider other federal law protections afforded them. One such protection would be the Plant Variety Protection Act (PVPA). Another protection would be the use of contracts. A company also may look at utilizing patent law to limit seed saving. You will need to consider each one of these to determine if saving the seed is allowed.
Nematodes are an economically important pathogen of many crops in Maryland. Significant yield loss can occur if nematodes are not managed properly. This factsheet serves as a broad introduction to nematodes as plant pathogens and serves as a general guide for sampling and managing nematodes in Maryland.
Most wheat and soybean seed sold in Maryland is protected by either U.S. Patent Law or the Plant Variety Protection Act (PVPA). These protections severely limit the age-old practice of “farmer-saved seed” or prohibit it entirely, depending upon the protection the owner of the variety secures. The following will discuss the implications of Patent Law and PVPA on farmer-saved seed of wheat and soybeans.
With the arrival of a new seed lubricant product, DUST, the University of Maryland evaluated its performance against two common seed lubricants in both corn and soybeans in 2019. DUST is a soy protein lubricant that is a cleaner alternative to commonly available seed lubricants, such as graphite which can create a mess for users of the product. It is also reported to contribute to early plant vigor.
