Wheat Resistant to Devastating Rust Fungal Diseases

Nature Biotechnology has published research—partially funded by The 2Blades Foundation—on the development of a new wheat variety that shows exceptional resistance to wheat stem rust. Stem rust is among the world’s most devastating plant diseases, with records of stem rust pandemics dating back over 2000 years. The stem rust pathogen Puccinia graminis is capable of completely destroying a crop of …

Effects of Dairy on Metabolic Risk Depend on Type of Product Consumed

Researchers have long been interested in understanding the effects of different types of dairy products on cardiometabolic health. Studies have looked at the effects of consuming different types of dairy on metabolic markers such as body weight, body fat, lean mass, or cholesterol. Although some studies have found that dairy products are associated with lower cardiometabolic disease incidence, other study …

Transform (sulfoxaflor) Full Label Could be a Major Benefit for Alfalfa IPM

The California Department of Pesticide Regulation is currently reviewing the use of Transform (sulfoxaflor) for insect pest management in alfalfa hay production. A decision on whether to register Transform with a label for use in California alfalfa is expected to occur by the end of 2020. The registration of Transform has been so far deferred due to concerns of potential …

$12 Million to Eradicate an Invasive Rodent of Unusual Size

You may have heard of them in the comedy film Princess Bride as “Rodents of Unusual Size”, but this is the real thing — only not so large and formidable.  Nutria were originally introduced into the United States as part of the fur trade in the late 1800s, but were eradicated from California in the 1970s.  They made a sudden …

Five Steps for Ag Processors to Adapt their COVID-19 Incident Response Approach

COVID-19 is a health crisis in the United States but major industries, like agriculture, chemical manufacturing, oil and gas exploration and production, all need to keep functioning as essential businesses in the midst of the crisis.  The response to COVID-19 has core parallels to major industrial accident response, which involves deploying the right resources for the task.  Every incident, be …

Insect-Deterring Sorghum Compounds May be Eco-Friendly Pesticide

Compounds produced by sorghum plants to defend against insect feeding could be isolated, synthesized and used as a targeted, nontoxic insect deterrent, according to researchers who studied plant-insect interactions that included field, greenhouse and laboratory components. The researchers examined the role of sorghum chemicals called flavonoids —specifically 3-deoxyflavonoid and 3-deoxyanthocyanidins — in providing resistance against the corn leaf aphid, a …

Improved Method to Test for Mycotoxin in Feed

California Department of Food and Agriculture (CDFA) Center for Analytical Chemistry (CAC) scientists Bahar Nakhjavan, Nighat Sami Ahmed, and Maryam Khosravifard were recently published in an academic journal after developing an improved method to test for mycotoxin in feed. Their article, “Development of an Improved Method of Sample Extraction and Quantitation of Multi-Mycotoxin in Feed by LC-MS/MS,” details their research …

Flavonoids’ Presence in Sorghum Roots May Lead to Frost-Resistant Crop

Flavonoid compounds — produced by the roots of some sorghum plants — positively affect soil microorganisms, according to Penn State researchers, who suggest the discovery is an early step in developing a frost-resistant line of the valuable crop for North American farmers. That is important because sorghum is a crop that can respond to climate change because of its high …

Recurrent Selection with Glufosinate at Low Rates Reduces Italian Ryegrass Resistance

Italian ryegrass is a major weed in orchards, vineyards, field crops, and fallow fields of California (Figure 1). Several different herbicides are used to control ryegrass and had been effective in reducing infestations until resistance evolved in many populations following repeated use of the herbicides. To date, resistance to glyphosate, paraquat, and some ACCase and ALS inhibitors has been confirmed …

$650,000 Grant to Study Wild Wheat to Help Prevent Diseases

The 2Blades Foundation and collaborators at the University of Minnesota, Kansas State University, and the John Innes Center will study wild emmer wheat to discover genes that can help farmers combat devastating wheat rust diseases which are estimated to cost farmers and consumers nearly $3 billion each year. The United States Department of Agriculture’s National Institute of Food and Agriculture …
