Bryce Gray, “Reports of crop damage resurfacing since Missouri dicamba ban lifted,” St Louis Post-Dispatch, August 4, 2017.
SUMMARY:
Reports that the dicamba ban in Missouri was lifted in Mid-July and farmers had resumed spraying. Damage reports are re-occurring. One farmer quoted in the story compares his Missouri acres where “every acre” is showing damage to his healthy soybean fields in neighboring Arkansas that has a similar dicamba ban in place. Some places showing damage are at least a mile away from any possible source of dicamba. Missouri’s ban was in place for less than a week after stricter conditions rules for spraying dicamba were issued targeting wind speed and the time of application. Monsanto is based in Missouri and some questioned the role their political power played in the lifting of the ban. FULL TEXT

Mario Parker, “Pesticide ‘Drifting’ Wreaks Havoc Across U.S. Crops,” Bloomberg, August 1, 2017.
SUMMARY:
Bloomberg reports on the dicamba damage numbers. Article includes key information from Monsanto about number of acres planted in dicamba-resistant soybeans (20 million) and cotton (5 million) in 2017. This represents about 25% percent of the national soybean crop and about half of the cotton crop, very significant numbers. FULL TEXT

Kevin Bradley, July 25, 2017, “Ag Industry, Do we have a problem yet?,” Integrated Pest and Crop Management, University of Missouri.
SUMMARY:
Article summarizes the total number of dicamba-related drift complaints as 1,411 as of July 19, 2017. Arkansas leads with 686 complaints, while Missouri has over 200. Estimates of acres damaged are up to 2.5 million. The author asks: “does 1,411 official dicamba-related injury investigations and/or approximately 2.5 million acres of dicamba-injured soybean constitute a problem for U.S. agriculture? …[M]y answer is an emphatic yes.” FULL TEXT

SUMMARY:
The Office of Pesticide Programs is transferring certain of the pesticide food and feed additive regulations that are now in 40 CFR parts 185 and 186 to part 180. These regulations are being consolidate because as a matter of law all of the
pesticide tolerances are now considered to be regulated under FFDCA section 408 as amended by the Food Quality
Protection Act (Public Law 104–17) and they no longer need to be separate. Includes dicamba tolerances. FULL TEXT

United States Department of Agriculture, “Monsanto Petitions (10-188-01p and 12-185-01p) for Determinations of Nonregulated Status for Dicamba-Resistant Soybean and Cotton Varieties: Final Environmental Impact Statement,”
December 2014.
SUMMARY:
The U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS) received two requests (petitions) from Monsanto Company, St. Louis, MO (Monsanto) seeking determinations of nonregulated status for genetically engineered (GE) plant varieties referred to as MON 87708 soybean and MON 88701 cotton, that have been engineered to be resistant to the herbicide dicamba (Monsanto, 2012b; 2012a). These GE plant varieties are currently regulated by APHIS, and Monsanto requests that APHIS grant the petitions (Petition 10-188-01p for MON 87708 soybean and Petition 12-185-01p for MON 88701 cotton), so that these varieties can be grown without any APHIS regulatory oversight. Since these two GE plant varieties are currently under APHIS regulatory oversight, the Agency requires
Monsanto to comply with a full range of safeguarding measures to ensure that these regulated GE plant varieties do not transfer or spread from their APHIS-approved outdoor planting sites. APHIS authorization is also required to move these regulated varieties interstate. Once a developer of a GE plant has obtained sufficient information to conclude that its regulated GE plant is unlikely to cause injury, damage, or disease to plants or plant products (i.e., pose a plant pest risk), it may submit a petition to APHIS to no longer regulate the organism. This is referred to as seeking nonregulated status. If a petition for nonregulated status is approved by APHIS, permits or notifications are no longer required by the Agency to grow or ship the GE plant throughout the United States and its territories. If APHIS determines that nonregulated status is appropriate for one or both the Monsanto GE varieties, they will no longer be subject to any regulations pursuant to Part 340. FULL TEXT
