Turfgrass grows in a complex environment that is full of stresses. For example, in the summertime, turfgrasses may be under abiotic stresses such as heat and drought stress. Some biotic stresses, such as summer patch and dollar spot disease, can occur at the same time. Situations like this cause stress for golf course superintendents and other turf managers. Some of these problems could be solved by cultural management methods; however, these methods can be labor intensive and expensive.
