Giving Farmers a Great Option Against a Costly Disease

When talking soybeans, all the attention recently seems to fall on the latest weed control technologies like Enlist E3® soybeans. However, even the best-yielding varieties with the newest traits can be compromised when phytophthora is present.

Phytophthora is the number one yield-robbing disease in soybeans, and pressures are increasing. A survey of soybean-growing states found a high proportion of isolates with virulence to Rps1c and Rps1k phytophthora genes. This means planting varieties resistant to these races may not be enough to keep phytophthora at bay. As we’ve seen with weed pressures, resistance can develop. The best approach to combat resistance is through a multi-pronged approach incorporating genetics, traits, and seed treatments.

To help protect your varieties, including those with strong agronomic profiles against phytophthora, Hoegemeyer Hybrids offers Lumisena® fungicide seed treatment, specifically developed to combat phytophthora.

Lumisena offers best-in-class protection against phytophthora through a unique mode of action which helps prevent resistance. Lumisena also demonstrates a yield advantage compared to seed treated with metalaxyl, which has traditionally been the seed treatment of choice for phytophthora.

As part of the LumiGEN® seed treatment recipe, Lumisena is combined with other effective ingredients to provide more complete protection to get seeds off to the strongest start. The LumiGEN offering for soybeans also includes:

  • EverGol® Energy: Protects against pythium, rhizoctonia, and fusarium
  • Gaucho®: Protects against multiple insects
  • L-2030R: Biological that promotes root growth, nodulation, and nutrient uptake while using biofungicide activity against rhizoctonia and fusarium

For those considering the latest in soybean trait technologies, including Enlist E3 soybeans, Lumisena can help protect your investment, especially in areas experiencing increased phytophthora pressure and potential resistance. Together with trait technology, seed treatments like the proprietary recipes of LumiGEN give farmers another way to help soybeans reach their potential from planting to harvest.


* Data is based on 638 head-to-head comparisons between Lumisena fungicide seed treatment (0.568 fl oz/cwt) and metalaxyl (0.75 fl oz/cwt) in the top 10 soybean-producing states through Dec. 12, 2017. Comparisons were made utilizing the same soybean variety. DO NOT USE THIS OR ANY OTHER DATA FROM A LIMITED NUMBER OF TRIALS AS A SIGNIFICANT FACTOR IN PRODUCT SELECTION
