Study:

Control of Pythium Blight on Perennial Ryegrass

Location:

Rutgers University – North Brunswick, NJ

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 bases, however, a stepwise rate response was evident from 1, 2, 4, and 6 oz/1000 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.
