Soybean quality issues have been found in several states last fall with Phomopsis seed decay, purple seed stain, and dead and moldy seeds. Phomopsis is a fungi that attacks seed pods and the seed itself causes poor seed germination, the budding of a seed after it has been planted in soil. Field Specialist in Agronomy, Wayne Flanary, says growers will have take into account the lower germination rates.
"Well, first of all, many of our companies use seed treatments which will aid in protecting the seed against the fungi that may be still on the seed coat. But secondly, one should also, if there is a poor germination meaning that the quality is just not there, a fungicide will not correct that."
With lower germination rates, Flanary advises growers to target a minimum of 120,000 plants per acre.
"That gives you kind of a ballpark to do that calculation. Of course there's an argument that of course we can go lower and still maximize yield. But the issue is that, the research shows that yes sometimes that will work, but typically we need 120,000 just to be on the safe side."
