Before we get busy with harvest, now is the time to evaluate disease issues you’ve had in your fields and formulate a proactive management plan for next year’s crop.
Of course, there are some variables each season we cannot control and cannot predict (temperatures, rainfall), but taking a mental survey of the successes and any issues you may have encountered this season can help with planning, and potentially better outcomes, for next season. By now, sudden death syndrome (SDS) and white mold issues may be evident in soybean fields. Though it is too late in the season for rescue treatments, now is the time to consider proactive management options for next year.
Product Selection. One of the first things to evaluate is product performance. Did your soybean product(s) seem well adapted and have adequate levels of resistance to problem diseases like SDS and white mold? If not, talk to your local agronomist or seed dealer about the availability of product resistance in your area.
Cultural Control. If diseases got out of hand, consider that you may now have a build up of inoculum in your fields and the same diseases may become more severe next year. Crop rotation for a minimum of three to four years or tillage may be necessary to destroy overwintering fungal structures prior to planting soybeans again. Dense, closed canopies can be conducive environments for soybean diseases such as white mold. Cultural practices that promote more open canopies, such as wider row spacing and lower plant populations, may reduce the severity of disease and may be necessary when white mold has been a significant problem.
Seed Treatments. ILeVO® Seed Treatment controls both the root rot and foliar phases of SDS with activity against nematodes including soybean cyst nematode. When paired with Poncho®/VOTiVO®, the seed treatment combination also provides soybean farmers with protection against early-season insects and broad spectrum nematode control. If SDS was a problem in your fields, talk to your seed dealer about Acceleron® Seed Applied Solutions ELITE plus ILeVO.
Your local agronomists, seed dealers, and Extension agents are great resources who are there for you, so don’t be afraid to reach out and ask questions or share your concerns.
