* Cinch from DuPont (Group 15, very long-chain fatty acid inhibitor) can now be applied as part of a sequential soybean weed control program. Metribuzin activity is very similar to what you would observe with Sharpen. The postemergence herbicide choices will be limited to Reflex, Flexstar, Flexstar GT (if RR soybeans), Prefix (Dual Magnum + Reflex) or Warrant Ultra (Warrant + Reflex). Waterhemp control with single active ingredient herbicides at 28 days after application. No more than 1.33 pints per acre of Cinch can be applied postemergence. Postemergence applications must be made before corn is 12 inches tall. Sulfentrazone (Authority/Spartan) use at least 6 ounces of the Authority/ Spartan 4F formulation. The waterhemp population evaluated was resistant to ALS (Group 2) inhibitors and glyphosate (Group 9). 2023 Meredith Corporation.

Our herbicides are formulated to help you control the toughest, most resistant weeds in a wide variety of crops. Controls Tough and Resistant Small-Seeded Broadleaves and Grasses Limited Carryover and Rotational Restrictions Many growers may avoid using group 14 herbicides at preemergence because of the potential for soybean injury. For POST applications, herbicide programs based on HG 27 will be essential to achieve broad-spectrum weed control (Figure 3). Thanks, Just wondering the performance for the guys that have used Fierce herbicide. Does the residual hold up? Soybean injury?? It does have a risk of injury to the beans, but usually at emergence with cool/wet weather..I've seen injury to the point of replanting..I've seen it work so good that only one post app was needed.darn good product. If youre having a major battle with waterhemp a few key points to keep in mind include the following: To get the longest residual control from soil-applied herbicide use in a premix, its important to have a high enough rate of the specific active ingredients. However, we strongly recommend using these active ingredients due to their high efficacy on waterhemp, long soil residual activity, and to reduce reliance on group 15 herbicides. Acetochlor (Warrant) use at least 20 ounces of the 3 lb formulation. Once resistant marestail gets any taller than 6 inches it becomes very difficult to control. Preemergence applications must be made within 3 days after planting and prior to soybean emergence. Foam .

Futures: at least 10 minute delayed. Choosing the soybean herbicide-tolerance trait will be more critical this year to use an effective POST herbicide program. Xtend, Enlist and Liberty Link traited soybeans are the choices that allow for effective postemergence control of multiple resistant marestail. Using full-labeled rates of herbicides and adjuvants will be very critical this year to avoid weed control failures and prevent an overflow of seed inputs to the soil seedbank. CONVENTIONAL CORN Use a standard grass herbicide at the full rate. managing herbicide resistance.

It will require a two pass (Pre and Post) herbicide program to provide season long control to minimize the spread of seed. However, activity of HG 1 herbicides on grass weeds (including volunteer corn) can be antagonized when tank-mixed with dicamba (Xtend/Xtendflex soybean), 2,4-D (Enlist soybean), or acetochlor. Beans are a large seeded broadleaf, corn is a grass, twh is small seeded broadleaf, shatter cane is a grass, burs and sunflowers are broadleaf's. By wiping out almost all of the grasses, you eliminate the need for expensive post-emerge grass herbicides and save yourself a bunch of money and yield. Richard-Pontvert SA Rue Hector Berlioz, Tullins, ara 38210 .

Apply 1 pint per acre of 2,4-D ester (4 lb gal formulations) to keep the preplant interval to 7 days, rates higher than that will lengthen the planting interval. In an effort to reduce some of the confusion around all of the herbicide premixes available, we broke up the data into smaller pieces by showing efficacy data for premixes containing flumioxazin (Valor), sulfentrazone (Authority/Spartan), metribuzin (Sencor/Tricor), and the group 15 herbicides in separate figures. It may be applied from corn emergence up to V8 stage or 30-inch tall corn (12-inches tall for sweet corn). Many of these products are based on HG 5 (metribuzin) and HG 14 (flumioxazin, sulfentrazone) (Figure 4). Strengths include pigweed, lambsquarters, velvetleaf and even some cocklebur and sunflower suppression.

Its a dicamba (Group 4, auxin agonist) formulation with the safener, cyprosulfamide. However, with the proliferation of premixed herbicide products, and some of the confusing marketing campaigns that we see, it can be difficult to pick a residual herbicide that best fits each weed control scenario. The presence of herbicide resistant marestail, tall waterhemp and palmer amaranth in New York is changing the way we manage weeds. I don't think you're supposed to use PPOs and illevo together. Farmers weigh to replant or not to replant, USDA Crop Progress Report| April 24, 2023. If necessary, a late postemergence rescue treatment of Cobra can be used. Fierce MTZ contains three effective modes of action that include metribuzin, flumioxazin, and pyroxasulfone. That's just me. Observe the DiFlexx label recommendations for adjuvants. Changed tips and the rest of the bean crop looked great. and most important strategy for .
