Managing SCN with Peking Resistance

Again this year, Peking is proving to be a reliable source of soybean cyst nematode resistance. While the majority of varieties have the 88788 SCN trait, nematodes appear to be adapting and developing resistance. Peking varieties are rising to the top as SCN adapts to other forms of resistance. SCN populations have been increasing, according to a study…Hear more


2020 Alfalfa Planning – Soil Sampling

Alfalfa is a pH-sensitive crop, doing best in the 6.8 to 7.0 range. That means soil sampling is critical to success. Sampling should be done every two to four years at about the same date, when crops are not growing. Knowing the soil pH levels makes nutrient management easier in the coming seasons…Hear more


Corn Harvest Timing

Natural drydown may have all but stopped in November. Some corn still has moisture levels above 30%, which presents a problem for harvest. Weakened stalks can be an issue with late harvests, and this season a host of factors have increased the risk of lodging. Because of these stalk issues, it’s important to evaluate fields to determine which to harvest first, despite moisture levels…Hear more

Corteva Agriscience Researchers Spotlight “Master Switch” Gene in Proceedings of the National Academy of Sciences

Scientists have long successfully employed single gene editing to add useful crop characteristics, such as insect control or herbicide resistance. However, locating a single gene to increase yield has proven elusive.

Despite this, researchers at Corteva Agriscience began looking at genes that function like master switches for growth and yield. They picked MADS-box genes, a group common in many plants, before settling on one (zmm28) to alter in corn plants. The challenge of working with genes that regulate development is making sure they turn on the right amount at the right time and in the right type of tissues.

“It’s awfully easy to get messed up plants,” if the genes are too active, said Jeff Habben, Plant Pathologist, Corteva Agriscience, who helped lead the research.

In field tests across U.S. corn-growing regions between 2014 and 2017, researchers found that the genetically modified hybrids typically yielded 3% to 5% more grain than control plants. Some yielded as much as 10%, researchers reported in the scientific journal “Proceedings of the National Academy of Sciences.”…Read more
