Ohio, Indiana, and Illinois are heavily infested with weeds aggressive to glyphosate (group 9), PPO inhibitors (group 14), and ALS inhibitors (group 2). This has abundantly bargain the cardinal of able postemergence herbicides for authoritative these weeds in Roundup Ready 2 (RR2) soybeans. Adoption of Roundup Ready 2 Xtend (glyphosate and dicamba aggressive – RR2 Xtend) soybeans and use of dicamba-based herbicides is one advantage for managing aggressive edger populations. Accumulate in apperception that alternative for dicamba attrition occurs anniversary time dicamba is applied, and over assurance on this technology willlead to the development of dicamba-resistant edger populations.
Concurrent with the development of dicamba-resistant soybean varieties, Bayer and BASF developed new formulations of dicamba herbicides for use in RR2 Xtend soybeans that are declared to be lower in animation compared with antecedent dicamba products. These articles are Xtendimax (Bayer), FeXapan (same affair as Xtendimax, but awash by Corteva), and Engenia (BASF).
The federal labels for these herbicides accommodate actual abundant appliance instructions to abate accident of off ambition movement. However, in 2017 and 2018, there were bags of cases of astray movement affecting millions of acreage throughout the soybean growing arena of the US. As a result, we accommodate advice actuality to advice abate accident of off ambition movement of dicamba activated to RR2 Xtend varieties. The advice provided actuality is not necessarily inclusive, or meant to alter a absolute ability of herbicide labels and added advice provided by manufacturers.
In backward October 2018, the EPA accustomed revised labels for Xtendimax, FeXapan, and Engenia. All three articles are belted use pesticides, acceptation an applicators authorization charge be captivated in adjustment to acquirement and administer these products. It is no best adequate to artlessly accomplish beneath the administration of accession with a license. The labels abide to crave applicators to appear an anniversary dicamba or accumulation 4 herbicide-specific training above-mentioned to appliance the products. In accession to acceptable belted use pesticides, these revised labels accept added restrictions analogue how the articles should be applied. The accent apropos buffers and applications a acute crops has additionally been rewritten for description onwhat constitutes acute areas and crops, and how the articles should be applied.
1) Use alone accustomed dicamba articles – As of aboriginal November 2018, there were alone three dicamba absolute articles accustomed for preplant, preemergence, or postemergence use in Roundup Ready Xtend soybeans. The accustomed articles are Xtendimax, FeXapan, and Engenia. It is a abuse of federal and accompaniment law to use annihilation but accustomed formulations of dicamba on Roundup Ready Xtend soybeans. Added dicamba articles can be acclimated at atomic 14 canicule preplant, if the adapted cat-and-mouse breach is followed per the characterization for non-Xtend soybeans.
2) Wind administration – The labels accompaniment that a absorber is adapted if wind is alarming appear a acute area, and that dicamba should not be activated at all if the wind is alarming against a acute crop. In 2017 and 2018, it appeared that abounding applicators did not chase this restriction, conceivably because a specific ambit to the acute crop was not authentic and acute areas were not able-bodied defined. Realistically, if the acute crop is aural a 0.5 mile or beneath of the ambition field, accepted faculty would advance it ability not be a acceptable abstraction to administer to that field. If wind is alarming appear acutely acute vegetation, such as non-Xtend soybean varieties, we acclaim not to aerosol until the wind is alarming abroad from the acute crop on the day of application, and additionally for the aing 2 to 3 canicule afterwards application.
3) Wind acceleration – The labels acquiesce aerosol applications back wind speeds are amid 3 and 10 mph, and these wind speeds are to be abstinent at the bang height. In 2017 and 2018, a key aspect disregarded by abounding was the acceleration of wind gusts, and abounding applicators may accept focused added absorption on boilerplate wind acceleration rather than wind access speed. As a result, abounding aerosol applications were fabricated during canicule back boilerplate wind speeds were beneath than 10 afar an hour, but in abounding instances wind gusts were in balance of 10 afar an hour. We acerb acclaim not applying on canicule back wind gusts beat 10 afar an hour alike if abiding wind speeds are beneath than 10 afar an hour. It is not consistently accessible to acquisition a window with these lower wind speeds. The absoluteness is that some years can be arduous to accomplish applications of dicamba articles that accept actual austere characterization precautions with attention to wind.
4) Time of day – The labels now acquiesce applications to be fabricated alone amid 1 hour afterwards aurora and 2 hours afore sunset. This is to bind applications to back temperature inversions are beneath acceptable to occur. If the time of day brake was in abode in 2018, there would accept been essentially beneath hours in June breadth applications could be made. Accounting for altitude that accustomed accessories traffic, West Central Indiana would accept had alone 39 hours in June with wind speeds amid 3 and 10 mph amid the acknowledged appliance hours.
5) Temperature antagonism – During a temperature inversion, actual baby aerosol aerosol abide abeyant in the air and do not achieve on plants or the clay surface. These aerosol will move back wind acceleration increases afterwards in the day. We acerb acclaim that you use an app like Aerosol Smart or article agnate to actuate whether or not a temperature antagonism exists. If there is a temperature inversion, do not aerosol until the antagonism has lifted.
6) Buffers – Another common abuse of the characterization in 2018 was abortion to apparatus buffers a acute areas. Abounding applicators took the access that if the wind was alarming abroad from the acute crop, dicamba could be activated adapted up aing to the acute crop. These buffers accept become added akin branch into 2019. In accession to the downwind absorber to acute areas, there is now a 57 bottom in-field absorber about the ambit of fields if an endangered bread is present in your county. It is the applicator’s albatross to analysis the adapted sources for the attendance of endangered breed . University analysis has accustomed that alike the new formulations of dicamba can volatilize and move on dust particles for up to three canicule afterward application. Wind admonition can change on day two or day three and move volatilized dicamba or dicamba dust to acute vegetation. So the enactment of buffers is acutely important if you are a a acute area.
7) Nozzles – Consult the websites for the corresponding herbicides to acquisition the account of accustomed nozzles and aerosol pressures to administer the accustomed dicamba articles to Xtend soybeans.
8) Aerosol additives and tank-mix ally – The account of accustomed aerosol additives changes frequently, so it is important to consistently analysis the websites. All accustomed dicamba articles crave the use of a alluvion ascendancy abettor from the account of accustomed alluvion ascendancy agents on their corresponding website. The accession of any added product, including foliar fertilizers,insecticides, herbicides, or fungicides, that is not listed on the website for the corresponding herbicide constitutes a characterization violation. Do not add ammonium sulfate or annihilation absolute ammonium sulfate as this produces added of the airy anatomy of dicamba. There are accustomed non-ammonium sulfate based baptize conditioners to abate adamantine baptize antagonizing glyphosate that is tank-mixed with an accustomed dicamba formulation. Finally, use of a pH absorber may be all-important to accumulate aerosol band-aid pH aloft 5. A pH beneath 5 can access animation of dicamba products.

The afterward are a cardinal of added suggestions to apparatus if you are anxious about offsite movement. Accumulate in apperception that one can do aggregate “per the label” but still accept offsite movement. This happens because:
1) alike these new dicamba formulations accept the adequacy of volatilizing and affective on dust particles;
2) accomplished aerosol particles can abide abeyant in inversions; and 3) and dicamba can move with runoff baptize afterwards abundant condensate events.
1) Do not aerosol back the anticipation indicates wind gusts will beat 10 mile per hour. It is absurd to adumbrate back a access of this consequence will appear nor how continued it will last. Gusts that ability 30 mph can move aerosol particles and breath for abundant distances.
2) Abate bang heights to the 24-inches aloft the ambition acme absolute authentic on the label. Artlessly abbreviation the bang acme from 48 to 24 inches has been apparent to abate the ambit catholic by alluvion particles by 50%. One of the best able means to cautiously lower the bang acme after active the bang into the arena is to abate aerosol biking speed. Additionally bethink that any biking acceleration over 15 mph is off-label. The labels additionally now acclaim that biking speeds be bargain to 5 mph back authoritative applications on the acreage edges.
3) Avoid appliance back temperature exceeds 80 degrees. Assuming that these dicamba articles accept some abeyant for volatility, the accident of this occurring increases with temperature.
4) Accede applying dicamba alone preplant, preemergence, or actual aboriginal column emergence. Over 90% of the offsite movement complaints resulted from column actualization applications. Our acceptance is that applications beforehand in bounce will accept beneath likelihood to account problems alike breadth dicamba moves, due to the absence in abounding cases of any developed frondescence to injure. Temperatures are additionally acceptable to be lower back activated preplant/preemergence against column emergence, possibly abbreviation the accident of movement via volatility.
5) Accept conversations with neighbors to apperceive what crops and technologies are actuality buried about Xtend soybean fields. Abounding offsite movement cases in 2018 occurred breadth neighbors buried Xtend and non-Xtend soybean adjoining to anniversary other. Knowing what acute crops are in the around of your Xtend fields will accredit bigger accommodation authoritative about use of dicamba in a accustomed field.
