Simazine injury

Simazine injury
Tom Zabadal , MSU Horticulture

Injury from this herbicide appears as yellowing in the leaves between veins that remain green. In more advanced stages, portions or the entire leaf becomes brown. As with diuron, simazine injury tends to occur on light soils and sites where erosion has exposed roots near the soil surface.
