Gil Gullickson, “Why Dicamba-Tolerant Soybean Technology is in Trouble,” July 11, 2017, Successful Farming,

SUMMARY:

This article reports on dicamba drift in Missouri, where damage to date is tallied at 203,045 acres on soybeans, as well as over 6,500 acres of other crops and gardens, including certified organic vegetable farms.   The damage appears to be caused both by known problems with how and when dicamba is sprayed, and also by greater than expected damage from legal and correct dicamba spraying of the newest varieties that are supposed to be low volatility: BASF’s Engenia, Dupont FeXapan Plus Vapor Grip Technology, and Monsanto’s Xtendimax with Vapor Grip Technology.  In response the Missouri Department of Agriculture voted on July 7, 2017 to temporarily suspend all sales and applications of dicamba.  FULL TEXT

Begemann and Skiles, 2017

Sonja Begemann and Susan Skiles Luke, July 10, 2017, “Arkansas, Missouri Ban Dicamba,” AgWeb.

SUMMARY:

Effective just after midnight on July 11, Arkansas finalizes a 120-day emergency ban on dicamba sales and use.  Missouri also banned dicamba the week before, with the intent of re-opening sales once the investigation into complaints of damage from dicamba drift is complete. The Missouri Soybean Association is quoted as saying that more than 200,000 acres of soybeans are affected in the state.  In a statement, Monsanto stressed the importance of “following label and local requirements” for their Roundup Ready Xtend Crop System of dicamba-resistant soybeans. The article lists the number of complaints of dicamba damage in Arkansas as “nearly 600,” up from the 500 reported on July 6, 2017.  FULL TEXT

Begemann, 2017

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.

Charles, 2017b

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

Hickey, 2017

Chris Hickey, “Legislative Panel Delays Decision On Arkansas Dicamba Ban,” July 6, 2017,  NPR.

SUMMARY:

Reports that the subcommittee of the Arkansas Legislative Council deferred a decision on whether to ban use and sale of dicamba.  Governor Asa Hutchinson referred the decision to the committee following hi approval of a 120-day emergency ban proposed by the Arkansas Plant Board.  The subcommittee did approve an emergency rule to increase fines up to $25,000 for misuse of dicamba.  All this follows the approval in December of BASF’s Engenia dicamba-based herbicide.  The board will re-convene to continue the debate the following week.

Associated Press, 2017b

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

Steed, 2017

Stephen Steed, “Governor approves dicamba prohibition in Arkansas,” Northwest Arkansas Democrat Gazette,

SUMMARY:

Reports that on June 31, Arkansas Governor Asa Hutchinson submitted a letter that approved the Arkansas Plant Board’s proposed 120-emergency ban on dicamba sale and use in the state.  He wrote that ” the volume of complaints do justify emergency action;” 507 complaints had been received as of June 31st.   The proposed ban next goes to a subcommittee of the Arkansas Legislative Council for review, although their approval is not required for the ban to take effect.   The article reports that complaints in neighboring states are also up, with 100 in Missouri and 48 in Mississippi as of the end of June 2017.  FULL TEXT

Bennett, 2017b

Chris Bennett, “Arkansas Dicamba Ban Passes, Heads to Governor’s Desk,” June 26, 2017, AgPro.

 SUMMARY:

Report on the vote of the Arkansas plant board on June 23 for a 120-day emergency ban on dicamba use after 242 complaints of damage from drift were received.   The article points out the huge problem of herbicide-resistant Palmer amaranth in Arkansas fields, and the issue of seed availability, estimating that in 2018 70-80% of the seed available will be of the Xtend GE-variety, creating a greater need for dicamba.

Bennett, 2017a

Chris Bennett, “Dicamba Drift Reports Rise in Tenessee,” June 26, 2017,  Ag Web.

SUMMARY:

Reports that as of June 26, Tennesse Department of Agriculture has open investigations on 27 dicamba drift complaints, compared to only 3 in the same time period last year. FULL TEXT

SUMMARY:

NPR story focusing on the farmer-vs-farmer conflicts arising in Arkansas due to dicamba damage.  By press date, 242 complaints had been received by state regulators.  On June 23, 2017 the Arkansas Plant Board voted to ban any spraying of dicamba on crops, other than pasture land, for 120 days.  The ban would take effect as soon as signed by the governor.  FULL TEXT
