Key points pulled from the episode

• ▸Timely application of residual herbicides is critical to prevent weed emergence.
• ▸Warmer temperatures are expected to increase growth rates of problematic weeds.
• ▸Bolero shortages prompt the use of Prowl as an alternative for grass control.
• ▸Tank mix compatibility issues need careful attention to avoid crop damage.

Key points pulled from the episode

• ▸Loyant coated on urea effectively controls aquatic broadleaf weeds in rice.
• ▸Weed size is crucial for effective control; smaller weeds yield better results.
• ▸Reduced off-target movement makes this method safer for nearby sensitive crops.
• ▸Challenges remain with controlling grass weeds like barnyard grass.

Key points pulled from the episode

• ▸Brake herbicide is now approved for use in peanuts under a Section 18 exemption.
• ▸Recommended application rates range from 12 to 16 ounces, depending on soil type.
• ▸Mixing brake with another herbicide like Valor enhances effectiveness.
• ▸Rainfall is critical for activating residual herbicides, with half an inch generally sufficient.

Key points pulled from the episode

• ▸Overlapping residual herbicides is crucial for effective weed control in row rice.
• ▸Timely applications every 14 days help prevent weed escapes.
• ▸Barnyard grass and Palmer amaranth are the top weed concerns for row rice.
• ▸Understanding the specific weed spectrum is essential for selecting the right herbicides.

Key points pulled from the episode

• ▸Hybrid rice is more susceptible to Loyant injury than inbred varieties.
• ▸Sequential applications of Loyant increase the risk of crop damage.
• ▸Environmental factors like temperature and soil moisture affect herbicide efficacy.
• ▸Glyphosate is ineffective against yellow nutsedge; alternative strategies are needed.

Key points pulled from the episode

• ▸Cotton acreage in Arkansas may decrease to under 500,000 acres this year.
• ▸Farmers are expected to plant up to 95% Xtend cotton, reflecting a shift in technology use.
• ▸Starting clean with effective residuals is crucial to manage resistant weed populations.
• ▸Mixing two residual herbicides is recommended for better control of pigweed and grasses.

Key points pulled from the episode

• ▸Phosphorus should be applied as close to planting as possible for optimal uptake.
• ▸Potassium has a wider application window and can be applied later in the growth cycle.
• ▸Zinc seed treatments are effective in marginal deficiency scenarios but require careful consideration of soil tests.
• ▸Starter fertilizers can help in cold, wet conditions but may not always lead to significant yield increases.

Key points pulled from the episode

• ▸Palmer amaranth is the primary weed concern in Arkansas soybean production.
• ▸Resistance to multiple herbicide sites of action is widespread, complicating control efforts.
• ▸Metribuzin remains a critical pre-emergence herbicide with no confirmed resistance yet.
• ▸Dicamba regulations are currently under review, creating uncertainty for farmers.
