Sonja Begemann, “Dicamba Damage Watch,” July 6, 2017, AgPro.
SUMMARY:
Describes the symptoms of dicamba damage – cupped and wrinkled soybean leaves – and other culprits that could be the cause such as other herbicide damage, pests such as aphids and various plant diseases. It can take 7 to 21 days for dicamba damage to appear, and it will only be evident on new leaves, not those present when the drift occurs. Percentages as low as 0.06 to 1.9% can cause damage resulting in yield loss. FULL TEXT
Dan Charles, “Damage From Wayward Weedkiller Keeps Growing,” July 6, 2017, NPR.
SUMMARY:
NPR Morning Edition radio piece reports that dicamba-related complaints in Arkansas are up from 250 at the end of June to 550 by July 6th. Estimates of potential damaged soybeans are up to 2 million acres. The new Monsanto dicamba resistant cotton and soybean is being blamed for this damage from an herbicide that has been in use for over 50 years. As one farmer quoted in the story puts it, “This technology cannot be allowed to exist. It cannot co-exist with other crops.” On the other side of the debate, farmers using the GE crops claim that dicamba is working great against the herbicide-resistant Palmer amaranth that is plaguing their fields, and Monsanto’s head of crop protection sees all this as “just part of the learning curve.” FULL TEXT

The board will re-convene to continue the debate the following week. FULL TEXT
Associated Press, “Farm chemical linked to oak damage,” July 2, 2017, Quad-City Times,
SUMMARY:
Reports that almost 1,000 residents of Iowa have contacted the state Department of Natural Resources about damaged leaves on oak trees (photo, right) that looked like insect damage. Research from the University of Illinois in 2004 showed that herbicide drift was likely linked to the condition, known as leaf tatters, due to exposure to chloroacetanilide herbicides like dicamba. Exposure occurs from direct drift but also through atmospheric volubility in areas not close to where the herbicide was applied. White oaks are particularly susceptible, and trees can die if damage to the leaves occurs over multiple years. FULL TEXT
