T. virens coils around hyphae of Rhizoctonia. Photo courtesy USDA-ARS-BPPDL R. solani T. virens

► Granular formulation containing spores of the fungus Gliocladium virens strain GL-21 Also known as Trichoderma virens Naturally-occurring beneficial fungus from soil ► Preventative fungicide for control of “damping off” diseases that prevent establishment of healthy plants and decrease yield. Kills pathogenic fungi, colonizes any that survive, and exclude recolonization. Phytophthora, Pythium, Rhizoctonia, Fusarium, Sclerotium, Sclerotinia, Macrophomina (charcoal rot), others ► Flexible application (chemigation, drench at plant, soil incorporation, transplant drench). ► Zero PHI & REI, signal word “Caution” ► Very safe environmental and safety profile. ► No special certification, documentation, plant setback restrictions required for use. It is not a fumigant. SoilGard ® 12G Biofungicide- Advantages

► Best started as a transplant drench prior to planting. ► Apply subsequent applications at 2-4 week intervals. ► Use as a preventative fungicide, 5 lbs/acre. ► Apply to warm moist (but not saturated) soil. ► Do not mix with other fungicides. SoilGard contains live fungus spores. Exception- Ridomil ► Use in soils at temperature of >60deg F. ► Do not apply until after fumigants have dissipated from treated soil. ► Always thoroughly mix SoilGard as it is being applied with continuous agitation. ► Either remove any filters from equipment prior to application or inject on the field side of any filters. SoilGard ® 12G Biofungicide- Use Pattern

Dr. Pingsheng Ji, University of Georgia, Tifton, GA (2010) Yellow summer squash (cv. Gentry) planted April 26. SoilGard applied as transplant drench 1 lb/100 gal, and then through drip at 5 lb/a 2 days before and 4 weeks after transplant. Ridomil Gold applied at transplant and 4 weeks after transplant. High natural Phytophthora blight disease pressure. SoilGard significantly decreased incidence of blight, leading to increased vigor and total yield, with a 25% increase in yield versus untreated. Results were similar to Ridomil Gold.

Dave Holden, Camarillo, CA (2009) Jalapeno peppers Natural but moderate pepper blight Phytophthora capsici Three applications of SoilGard at 1 lb/100 gal or 5 lb/a (2 weeks before plant as transplant drench, 3 days and 4 weeks post plant), compared to three applications of Ridomil SL Gold at 1 pt/a plus phos acid (3 days post plant and 4 and 6 weeks post plant). Count of dead or dying plants weekly through the trial. Results showed SoilGard had consistently numerically lower plant infection and mortality through the trial compared to the untreated and the grower standard Ridomil plus Phos acid.

Dr. Mike Nelson, Plant Services Inc., Watsonville, CA, (2008) Strawberry cv. PS-1296 planted 11/19. All plots treated with methyl bromide plus chloropicrin prior to transplanting. SoilGard applied as a transplant drench 2 lbs/gal for 5 min. on 11/19 plus drip application at 5 lbs/acre on 2/12, or as a drip application (alone) on 2/12. Low soil borne disease pressure. Harvest data combination of all harvest dates twice weekly, April through September. Yield from SoilGard plots was greater than untreated control plots by 7.8% for pre-plant transplant dip plus post-plant drip, and 4.7% for post-plant drip alone. Value of yield increase (6 $/crate or flat, 2500 crates per acre) with SoilGard (two applications) versus UTC was 1170 dollars per acre.
