Golf course superintendents prepare for Zoysia Patch & Large Patch outbreaks
Trinity™ fungicide continues to get more exposure in the zoysia patch segment. Every golf course superintendent I’ve spoken with after using Trinity has been very pleased with the results. Fall and spring applications at 1-2 oz. are the standard recommendation here in the Ohio Valley. Some will go with 2 oz. in the fall then 1 oz. in the spring; a few might go 2 and 2, and some are going down with 1 and 1.

Rapid Blight conditions ripe as the Southwest enters fall/ winter months
Rapid Blight is not a new disease. It’s been around for a while and affects the Southwestern states particularly in the fall/winter months of September, October and November. Rapid Blight occurs predominantly because of poor quality irrigation water with high salinity.

Conditions favoring this disease are usually seen in the late summer and early fall as salt build up in the soil becomes elevated due to irrigation water with high sodium content and/or naturally occurring high sodic soils. Rapid Blight is characteristic of its name, and infection is usually very devastating to turf greens and fairways if left untreated. The disease causes rapid decline and death of cool season grasses, thus in Bermuda greens or fairways, which are over seeded for the winter dormant period, the disease can be devastating.
