• ▸Understanding local weather patterns is crucial for effective pesticide use.
• ▸Aerial applicators are generally more aware of inversion risks than ground applicators.

Key points pulled from the episode

• ▸Sharpen herbicide is in short supply, affecting burndown options.
• ▸Alternatives like Valor and Reviton may not be as effective as sharpen.
• ▸The choice between 2,4-D ester and amine is crucial for early-season applications.
• ▸Farmers are encouraged to consider fall residuals to manage ryegrass effectively.

Key points pulled from the episode

• ▸Widespread glyphosate resistance in Italian ryegrass is confirmed across Arkansas.
• ▸Imazamox resistance is also significant, with potential paraquat resistance being investigated.
• ▸Timely application of fall residual herbicides is critical for effective ryegrass control.
• ▸Cover crops may offer a new strategy for managing ryegrass populations.

Key points pulled from the episode

• ▸Harvest aids should ideally be applied at R6.5 to R7 growth stages.
• ▸Applying aids too early can result in up to 68% yield loss.
• ▸Late-season weed management is critical for a successful harvest.
• ▸Environmental conditions this year have been challenging for soybean crops.

Key points pulled from the episode

• ▸Narrow row spacings (5-10 inches) improve canopy coverage and weed control.
• ▸Wider rows (15 inches) delay canopy closure, allowing more weed growth.
• ▸Nozzle droplet size affects spray coverage but not weed control effectiveness.
• ▸Ongoing research aims to validate preliminary findings with more data this season.

Key points pulled from the episode

• ▸Field days on August 5 and 10 will focus on rice and soybean management.
• ▸Dry conditions are complicating weed control efforts, particularly with pigweed.
• ▸Herbicide contamination is a growing concern, necessitating careful management practices.
• ▸Producers are exploring new application methods to improve herbicide effectiveness.

Key points pulled from the episode

• ▸Salvage treatments for barnyard grass in rice include Rice Star with Regiment or Beyond.
• ▸Roundup mixed with Liberty is effective for grass control in soybeans and cotton.
• ▸Timing of herbicide applications can impact both weed control and crop yields.
• ▸Dicamba and glyphosate should not be mixed due to legal restrictions and antagonism.

Key points pulled from the episode

• ▸Zidua applied via fertilizer is gaining traction for pigweed control.
• ▸Dicamba and 2,4-D are less effective against resistant pigweed populations.
• ▸Grass control remains a significant challenge, exacerbated by dry conditions.
• ▸Separating glyphosate and dicamba applications improves grass control outcomes.

Key points pulled from the episode

• ▸Rogue requires deep water for optimal herbicidal activity.
• ▸Growers must complete training to use Rogue effectively.
• ▸The herbicide is effective against sprangletops and annual sedges.
• ▸Patience is crucial as Rogue's effects take longer to show than traditional herbicides.

Key points pulled from the episode

• ▸Coating herbicides on fertilizers can reduce off-target movement.
• ▸Loyant effectively controls specific weeds when coated on urea.
• ▸Novixid adds grass control capabilities but is less effective than spraying.
• ▸Timing of application and weed size are critical for success.

Key points pulled from the episode

• ▸Farmers in Jackson County are still planting soybeans into late June due to weather delays.
• ▸Increased cotton acreage raises concerns about herbicide drift affecting neighboring crops.
• ▸Effective management of resistant pigweed requires timely herbicide applications and careful monitoring.
• ▸Overlapping residual herbicides is crucial for controlling weeds, especially in row rice systems.

Key points pulled from the episode

• ▸Residual herbicides require timely activation through rainfall or irrigation to be effective.
• ▸Recent dry conditions in Arkansas are raising concerns about herbicide efficacy after wet planting periods.
• ▸Farmers are encouraged to apply residuals before planting to ensure activation before weed emergence.
• ▸Pairing different herbicides can enhance weed control and resistance management strategies.
