The Environmental Protection Agency has registered Saltro fungicide soybean seed treatment from Syngenta to control sudden death syndrome and nematodes.
The seed treatment contains the active ingredient Adepidyn, the brand name for pydiflumetofen, an SDHI fungicide. It belongs to the Fungicide Resistance Action Committee’s Group 7. Saltro does not control Pythium spp., Phytophthora spp. or Rhizoctonia spp., according to the label.
“For the first time ever, growers will have a seed treatment option for protecting their soybeans against SDS and nematodes that doesn’t cause additional stress on the plant and enables soybeans to reach their full genetic potential,” Dale Ireland, technical product lead for Syngenta Seedcare, said in a news release. “With Saltro, we’ve seen a statistically significant yield increase of 3 bu/A over the current standard in heavy SDS environments. It’s definitely an upgrade for SDS protection.”
The trials in which the yield increases were seen had 20% SDS incidence or more as measured by a local scientist in Syngenta Seedcare trials in 2015-2017. Trial locations were in Arkansas, Illinois, Iowa, Kentucky, Michigan, Minnesota, Tennessee and Wisconsin.
Saltro also has strong activity across a broad spectrum of nematode species, including soybean cyst nematode — the No. 1 yield-robbing pest in soybeans and a major contributor to SDS infection, according to the release.
