Mode of Action

Azoxystrobin, the active ingredient (AI) in Heritage Maxx®, is taken into turf blades quickly for protection upon application. However, a significant portion of Heritage Maxx remains on the leaf surface. Upon irrigation, rainfall, or even a heavy dew, this remaining AI is washed down the surface of the turf. Some is then absorbed into the leaf, but the majority of Heritage Maxx moves into and through thatch to the soil. Here it is further absorbed by the roots to control soilborne diseases and continues up through the entire turfgrass plant for additional foliar protection.

Mode of Action: Respiration inhibitor
