New active ingredient for seed treatments
Valent has had ethaboxam in research for eight years and has tested it in the field in combination with its metalaxyl fungicide active for six years, McDuffee said. During the research on ethaboxam, it provided good control of oomycetes, but when combined with metalaxyl, the combination offered better results.
Research shows the two actives are very complementary products. “Their physical properties mix well and you’re really going to get consistency, you’re going to increase the number of situations where you get adequate control even when you’re planting early and into problem soils or you have moisture issues early in the year,” McDuffee contended.
He explained that the two modes of action combination works well on multiple species to better protect the seed/seedling from oomycete pathogens such as Pythium and Phytophthora.
“We’re finding that a farmer could be battling up to five to 10 different Pythium species in a field. So, we think our two modes of action system will offer a broader spectrum of control, and based on the different physical properties of ethaboxam and metalaxyl together, you’re going to be able to control seedling diseases better and get that early stand establishment.”
