Share Facebook Twitter Google + LinkedIn Pinterest Soybean herbicide systems have evolved back to a fairly high level of complexity to deal with the herbicide resistance we have in various broadleaf weeds. By the time we use a comprehensive mix of burndown and residual herbicides, we tend to be coming back with postemergence herbicides primarily for marestail, ragweeds, and waterhemp (and grasses). Postemergence tools available for control of these broadleaf weeds vary with the type of soybean trait being used, but can include glyphosate, PPO inhibitors (fomesafen, Cobra), glufosinate, dicamba, and soon 2,4-D choline. ALS inhibitors have become somewhat irrelevant on these weeds due to widespread ALS resistance, although they may have activity on some ragweed populations still sensitive to ALS inhibitors. Resistance to various sites of action can further limit the number of options.The following generalizations about resistance seem appropriate at this time:• Marestail — almost all populations are resistant to glyphosate and ALS inhibitors• Common ragweed — populations in some areas/fields are resistant to glyphosate and ALS inhibitors, and in some cases also PPO inhibitors. Other populations still largely respond to all of these herbicides• Giant ragweed — most populations have lost sensitivity to glyphosate and some are resistant. Many populations also resistant to ALS inhibitors, especially if they have glyphosate resistance. No confirmed PPO resistance yet.• Waterhemp — all populations are resistant to ALS inhibitors, most are resistant to glyphosate, some are resistant to PPO inhibitors also. Resistance is more widespread in areas/fields with longest history of waterhemp problems.In soybeans, we assume that regardless of the residual herbicides used at planting, giant ragweed and waterhemp will require postemergence herbicides. The same can be said for common ragweed that has resistance to ALS inhibitors — flumioxazin can provide some residual control of these populations but not to the point that postemergence herbicides are unneeded.Marestail is the one weed in this group that can often be adequately controlled with residual herbicides (assuming an effective burndown). Residual control of marestail is essential in RoundupReady and non-GMO soybeans, since there are no postemergence options. Residual control is also vital in Xtend soybeans, if the goal is to use dicamba only in burndown programs, avoiding postemergence use.Off-target movement of dicamba, which was widespread in 2017, has much greater potential to cause problems from postemergence application. University weed scientists are fairly united in their opinion that dicamba use would be better restricted to early season, in burndown programs. The other three weeds mentioned here do not necessarily require postemergence dicamba use, since glyphosate/PPO inhibitor combinations can still be effective. However, failure to use an appropriate residual program in Xtend soybeans can result in mid-season marestail escapes, driving a need for postemergence dicamba.We have been making the same residual herbicide herbicide recommendations on marestail for several years, and they are based on the following:• The ALS resistance means that the chlorimuron, cloransulam, or imazethapyr that is in many residual premixes provides no residual control.• The only other active ingredients with residual activity are metribuzin, flumioxazin, and sulfentrazone. Higher rates of Sharpen provide some residual. Dicamba and the 1-ounce rate of Sharpen provide negligiable residual which is short-lived.• The residual activity from any one of these actives varies from year to year and field to field in our research, resulting in inconsistent control. Control with metribuzin has been rate dependent — increasing with rate from 6 to 12 ounces of 75 DF.• Mixtures of two active ingredients provide more consistently effective control, which is the basis of our recommendation to add 6 to 8 ounces of metribuzin 75 DF to products that contain flumioxazin or sulfentrazone. It’s also possible to improve control by using 1.5 to 2 ounces of Sharpen with metribuzin, but this requires a 15- to 30-day wait to plant.Based on this we can put premixes roughly into one of three categories with regard to residual marestail control: most consistently effective (two actives), variable (one active); and no control. This information can also be gleaned from the marestail ratings in the herbicide efficacy tables in the “2018 Weed Control Guide for Ohio, Indiana, and Illinois.” We can’t keep track of all generic equivalents so there are more trade names available for certain premixes than are listed here. Keep in kind that just because a premix contains the right components for maximum marestail residual does not mean it has the right ones for ragweeds. Most consistent residual (two actives), higher labeled rates required in some casesPanther Pro, Trivence, Authority MTZ, Ransom Variable residual (one active)Afforia, Authority First/Sonic, Authority MAXX/XL, Authority Assist, Zone, Broadaxe XC, Envive/Enlite, Fierce, Fierce XLT, Latir/Militia, Surveil, Valor XLT Variable residual sub-category — more metribuzin is needed depending upon product rateCloak DF, Canopy Blend, Matador, Intimidator, Boundary/Ledger/Tailwind No or little residualAnthem MAXX, Prefix/Vise/Statement, Pummel, Torment, Warrant Ultra, Zidua PRO Deficiences in residual on marestail for individual premixes can be compensated for by the strategies outlined above. For example, Zidua PRO has almost no residual activity on marestail, but is often applied with metribuzin. In this and any other case where metribuzin is carrying the full load, rates of 10 to 12 ounces 75DF will be more effective than 6 to 8 ounces. Some products contain metribuzin, but require additional amounts to reach a total metribuzin rate that has a chance to provide enough residual. Example: 4 ounces of Canopy Blend contains the equivalent of 2.7 ounces of metribuzin 75 DF, so our recommendation would to add about another 4 to 8 ounces of metribuzin 75DF, depending upon soil type.
Share Facebook Twitter Google + LinkedIn Pinterest By Alexander Lindsey, Rich Minyo, Allen Geyer, Peter Thomison, Ohio State University ExtensionFarmers who still anticipate planting corn for grain production should review their hybrid maturities to minimize the risk of corn not maturing safely prior to a killing fall freeze. We would encourage the use of the Corn GDD Tool to select “safe” hybrid maturities for late planting (http://www.kingcorn.org/news/timeless/HybridMaturityDelayedPlant.html).Although they are not planted as widely as our commonly grown maturities, hybrids with relative maturities of 100-104 day maturity are likely to achieve physiological maturity if planted by mid-June throughout most of the state. There is limited information on the agronomic performance of hybrids with maturities less than 100 days. Since these “ultra-early” hybrids were not developed to be planted in Ohio, they are regarded as less adapted to growing Ohio conditions and more susceptible to disease and stalk quality problems. Because of their questionable yield potential, ultra-earlies are typically not recommended in late planting situations.In recent trials conducted at OSU in 2016-2017, ultra-early hybrids (90-100 day) were compared to more common CRM hybrids (104-109 day) for agronomic performance. Planting dates were May 23 and June 2 in Crawford County in 2016 and 2017, and May 23 in Wayne County in 2017. All hybrids were harvested on the same date within a site each year. Growing conditions were very favorable for corn production at these sites.While yield and return were greatest for the 104-109 day hybrids, the return per acre was similar to the 96-100 day hybrids statistically (as indicated by the asterisks) due mainly to discounts on the 104-109 day hybrids from low test weights and high harvest moisture. The performance of the 90-95 day lines was consistently below the other groups tested but still produced substantial yield. In 2018, when planting dates were mid-May at each location, the yield and return were greater with the 104-109 day hybrids compared to the ultra-early hybrids. When considering changes to relative maturity for late planting, this may help in the decision-making process. Earlier maturity hybrids may incur less drying costs and have higher test weights, but may have a slight yield disadvantage compared to the 104-109 day hybrids. However, these results and observations are based on limited test data that may not apply across a wider range of production environments,especially those outside northcentral/northeastern Ohio.We would strongly encourage those producers to consult with their seed company agronomist before changing to hybrids with a relative maturity less than 100 days. Check hybrid disease ratings for foliar diseases (esp. gray leaf spot and northern corn leaf blight), stalk rots and ear rots as well as dry-down characteristics.

It’s not how smart you are.There are people who are succeeding wildly now who are nowhere near as smart as you are. You know more than they do, and you may have a higher IQ, but they are still producing better results than you are in some area.It’s not all EQ, either.There are people who have less emotional intelligence than you have who are generating incredible results. Even though they lack empathy and have limited self-awareness, they are still successful by some measurement.It’s not resources alone.Some of the people who are producing the results that you want don’t have anywhere near the resources that you have. They don’t have the money or the connections that you have. But they are succeeding in some area where you are struggling.It’s not potential.There are some people with far less potential than you have who are out-producing you. On some measure, your results should be way better than the results they’re getting. But you lag far behind them.The difference between you and the people who are producing better results in an area where you would like to be producing those same results is that they have different beliefs and take different actions.Hustlers don’t feel a sense of self-doubt. When they do, it doesn’t stop them from acting. They don’t believe that they are incapable of producing the results they want in their lives.Hustlers don’t believe they will fail, and they aren’t ashamed when they do. They don’t allow their fears to stop them from acting.Hustlers don’t feel that they need permission, a certificate, or some external validation. They move forward, doing what they want to do, and they figure things out as they go.And hustlers aren’t comfortable being comfortable. They have to be more and do more. They can’t not hustle.You have the same potential as the hustler. The difference is in your beliefs and your actions.

(Photo by Kevork Djansezian/Getty Images)The song is surely burned into the memory of every college football fan. So much so that one likely can’t listen to the lyrics without thinking about Ohio State or Oregon or Florida State or Alabama or ESPN. Some legends are told, some turn to dust or to gold But you will remember me, remember me for centuriesIt’s Fall Out Boy’s “Centuries” and it was the theme song of the inaugural College Football Playoff. It was played an insane amount of times during the two semifinal games and the championship game. How many times, exactly? According to the Reddit user, Emperor_of_Orange, 45 times – 10 times in the Rose Bowl, 18 times in the Sugar Bowl and 17 times in the CFB Playoff National Championship Game. Here it is for hopefully one, final time.
