News You Can Use

When something threatens yield, identifying the root cause is as important for long-term success as knowing how to properly manage the immediate threat. Pioneer agronomists help growers tackle urgent problems and plan for the long term to achieve the best results year after year.

This week’s briefs cover the role clouds play in solar radiation, CRISPR-Cas and managing viral wheat diseases.

Clouds and Solar Radiation

Plants can use only about 43% to 50% of the total solar radiation spectrum. This usable portion is known as photosynthetically active radiation (PAR). Cloud cover reduces PAR by about 25% to 50% on partly cloudy to cloudy days and by more than 60% on rainy days. Not surprisingly, cloudy, rainy periods during susceptible stages of crop development can have significant impact on yield…Read more

CRISPR-Cas Advanced Plant Breeding

Many bacteria protect themselves from invading viruses by using adaptive immune systems called CRISPR-Cas. These CRISPR-Cas systems can recognize genetic sequences specific to that of invaders and cut them. Pioneer is a world leader in CRISPR-Cas, harnessing these systems as molecular scissors to make cuts at specific locations in a plant genome. This powerful genome editing tool promises to help Pioneer scientists develop better crops faster and more efficiently than ever…Read more

Managing Viral Diseases in Wheat

Viruses, leaf diseases and head diseases may all affect a wheat crop and reduce yields by as much as 50%. Diseases are generally worse in spring during prevailing wet weather patterns. Selecting resistant varieties is an important first step for managing wheat viral diseases…Read more

Corteva Agriscience Accelerating Enlist E3™ Deployment Over Next Five Years

Corteva Agriscience announced it is accelerating the ramp-up of Enlist E3™ soybeans to U.S. and Canadian farmers over the next five years — reinforcing the company's commitment to its Enlist technology and continued focus on bringing greater choice and value to growers.

Corteva continues to see strong demand for the technology from farmers, retailers and independent seed companies. It expects planted acreage projections in 2020 to approach 20% of the U.S. market — double original expectations.

"The decision to accelerate production of Enlist E3 soybeans, along with the Enlist One® and Enlist Duo® herbicides, ahead of the 2021 selling season, reflects our continued focus on rapidly ramping up differentiated technology solutions that we expect will enable greater choice and value for growers over time," said James C. Collins Jr., Chief Executive Officer. "Our Enlist weed control system illustrates the power of Corteva across platforms, integrating seed and chemistry — providing much-needed solutions to farmers that address complex challenges, such as weed resistance, while strengthening Corteva's proprietary trait offering."…Read more
