CHAPTER 6: Fungicide Interactions

From a turf-health-management perspective, fungicides interact with other practices for maintaining fine turf. In Chapter 4, management practices were discussed in terms of their effects on disease pressure and, hence, their influence on fungicide performance. In this chapter, three particular types of fungicide interactions are considered: interactions between fungicides in mixtures, synergism in fungicide combinations, and interactions between fungicides and plant growth regulators.
