Title Phyte Systemic Fungicide

Study:

Control of Pythium Blight on Perennial Ryegrass

Location: Rutgers University Collaborator: Bruce B. Clarke, Ph.D. Date: Summer 2021 Conclusion:

Title Phyte Systemic Fungicide showed excellent control of Pythium blight on this highly susceptible stand of young perennial ryegrass (seeded 6/11/2021). All rates of Title Phyte Systemic Fungicide provided significant disease control on a preventive basis, however a stepwise rate response was evident from 1, 2, 4, and 6 oz/1,000 sq ft respectively. Pythium control with Title Phyte was similar or better than current industry standard fungicides. This trial further confirms the benefit of incorporating Title Phyte into a balanced approach program for plant health, supplemental nutrition, and preventive control of important diseases like Pythium blight.

Figure 1: Data from two rating dates (July 2 and July 19) when Pythium blight symptoms were highest. Note the significant control with all Title Phyte treatments vs the Untreated control and similar control to other industry standard Pythium fungicides.
