Frogeye leaf spot is always a major worry for soybean growers in the summer and now Syngenta is suggesting growers use Quadris Top SBX fungicide, which has multiple modes of action for prevention.
Resistance of Frogeye leaf spot is on the rise among soybean plants that only used solo-strobilurins, according to the North Carolina Cooperative Extension research.
“Whether it’s 2016 or further down the road, soybean growers using fungicides containing one active ingredient with a single mode of action won’t see the same benefits as they have in the past,” Eric Tedford, Syngenta's fungicide technical product lead, said. “Beyond controlling other key diseases, Quadris Top SBX gives soybean growers confidence in controlling frogeye leaf spot, resistant or not, and the opportunity to maximize the yield potential of their soybeans.”
Two active ingredients in Quadris Top SBX, azoxystrobin and difenoconazole, provide plants with preventive, curative and systemic disease control. As a result of the strong active ingredients, soybean yields were up an average of six to eight bushels per acre in multi-year trials of Quadris Top SBX vs. untreated soybean fields.
