Performance of Pioneer® Brand Soybeans with ILeVO® Fungicide Seed Treatment Against SDS
Background and Objectives
ILeVO® fungicide/nematicide seed treatment (active ingredient: fluopyram) provides protection of soybean seedlings from Fusarium virguliforme infection, the causal agent of sudden death syndrome (SDS). ILeVO fungicide/nematicide seed treatment also has activity against soybean cyst nematode (SCN).
- DuPont Pioneer researchers conducted trials in 2012 through 2015 evaluating ILeVO fungicide/nematicide seed treatment performance against SDS in soybeans.
Years: 2012, 2013, 2014, & 2015
Plot Design: Replicated research trials
FST + IST (fungicide seed treatment/insecticide seed treatment)*
FST + IST + ILeVO fungicide/nematicide seed treatment (1.18 fl oz/140k unit)
*FST = EverGol® Energy fungicide + Allegiance® fungicide; IST = Gaucho® insecticide
SDS: When soybean plants exhibited late-season SDS symptomology the locations were characterized as SDS locations; if no SDS symptomology was present then locations were characterized as non-SDS locations.
Soybeans treated with FST + IST (left) and FST + IST + ILeVO fungicide/nematicide seed treatment (right) at a trial location in Johnston, IA with SDS symptomology (August 2015).
- Over 4 years & 165 locations, the addition of ILeVO fungicide/nematicide seed treatment to the base FST + IST increased soybean yield 2.0 bu/acre (71% Wins).
- Among locations without SDS symptoms (n=119) yield was increased by 0.3 bu/acre, compared to a 6.4 bu/acre increase at locations where SDS symptoms were observed (n=46).
