Plant Stress

Jul 13, 2010

Eric Tedford

Stress seems to be a way of life anymore, and we find ways to combat the stress with exercise, hobbies and yoga, for example. Plants undergo stress and it hurts them just as it does us, and as we know from our own experience, one stress usually leads to another. 


One stress that has been a problem the last few years is rain.  Last year, heavy rainfall delayed planting, maturity and harvest for farmers across the Midwest. Some Midwest states have recently experienced too much rain and are having issues with planting or replanting.


Reports from the University of Missouri say the wet weather may help fuel the development of Septoria brown spot and frogeye leaf spot in soybean. You can be proactive and help prevent yield loss by applying a preventive strobilurin fungicide, when conditions are conducive to disease. Strobilurin fungicides have proven disease prevention and may offer plant physiological benefits throughout the season.


If a season isn’t too wet, then it might be too dry.  In 2009, the combination of drought and a deep freeze was responsible for close to 50 percent crop loss in some areas of the Southwest.  You can help ease your plants’ stress by helping them preserve water and use it more efficiently.  Remember that fungicide you applied to protect your corn against disease?  Check to see if it increases water use efficiency, because if it’s a strobilurin, it does. 


This year your plants could be put under any number of stressors which could lead to more stress in your life!  Since your plant can’t do yoga, applying a strobilurin fungicide can be an important step in reducing potential stresses in 2010. 

Has weather been a stress in your area?
