Early season weed competition can be detrimental to yield, therefore, effective herbicide options are crucial for a successful weed control program. Not only is weed competition a physical challenge for growers, it also can have a significant financial impact. With just eight plants per meter, yield loss in soybean can be up to 56 and 79 percent for waterhemp and Palmer amaranth, respectively.1 Dicamba-based herbicides, like Engenia® herbicide, provide consistent and reliable control of weeds that have developed resistance to other chemistries.
Based on BASF’s proprietary BAPMA technology, Engenia herbicide offers the most advanced dicamba formulation on the market. It has the lowest use rate available for dicamba-tolerant crops and offers the lowest volatility dicamba salt. Engenia herbicide controls more than 200 broadleaf weeds, including many that have developed a resistance to glyphosate, and provides an additional effective site of action.
When using dicamba over the top of DT soybeans and cotton, it is important to minimize potential of volatility and drift. In addition to following all federal and state label requirements, agronomic experts at BASF recommend additional best practices to keep dicamba applications on target every time.
“With increased weed resistance, the need for dicamba-based herbicides, like Engenia herbicide, is greater than ever before,” said Andrew Adams, BASF Stewardship Manager. “Product stewardship is a fundamental part of what we do for our products. For Engenia herbicide, we are constantly looking for solutions that further reduce the risk of off-target movement for every application.”
Planning to apply a dicamba-based herbicide? Here’s a quick checklist:
- Use an approved pH buffering adjuvant, like Sentris™ Buffering Technology, in every application. Unlike other dicamba formulations, Engenia herbicide does not always need an additional drift-reducing agent. Refer to EngeniaTankMix.com for a list of approved pH buffering adjuvants and other tank mix partners.
- Use approved nozzles and tank mix partners.
- Only spray when wind speed is between 3 and 10 mph.
- Only apply one hour after sunrise and until two hours before sunset.
- Spray at a ground speed of 15 mph or less.
- Follow EPA spray buffer requirements, accounting for windspeed and endangered species assessment requirements.
- Limit to two post over-the-top applications.
- Create records within 72 hours, including applicator, product and planting information, application parameters, pH buffer adjuvant and use rate, tank mixes, tank cleanouts, spray conditions, and spray buffer zones.
- Follow all state and local requirements.
- Do not spray if wind is blowing toward neighboring sensitive crops, residential areas or other sensitive areas.
- Do not apply when temperature inversions exist at the field level.
- Do not apply after cutoff dates (June 30, 2021 for soybeans and July 30, 2021 for cotton).
