The Plant Management Network announces its latest webcast presentation published in its Focus on Soybean resource: Yellow Flash in Soybean by Dr. Mark Bernards at the University of Nebraska-Lincoln. Yellow flash is the temporary chlorosis of newly emerging soybean leaves that sometimes occurs following the application of glyphosate to glyphosate-resistant soybean cultivars.
According to Bernards, the most likely cause is a reduction in chlorophyll content caused when environmental conditions are warm and moist, favoring rapid soybean growth, and/or when high rates of glyphosate are applied. These findings will be useful to growers and consultants and provide reason to reconsider foliar applications of manganese as a solution for this issue.
This presentation specifically covers:
- The conditions most favorable for yellow flash
- How glyphosate works when applied to glyphosate resistant varieties
- Management of yellow flash
- The relationship of glyphosate and manganese in soybean growth and yield
