What does tolerant turfgrass refer to in pest management?

Tolerant turfgrass in pest management refers to healthy turf that can withstand the pressures of pest populations without suffering significant damage or decline. This type of grass has developed various physiological and biological mechanisms that enable it to cope with pests more effectively than susceptible varieties. Tolerant turf typically maintains its aesthetic quality and functionality even when exposed to pest stressors, reducing the need for chemical interventions and promoting more sustainable pest management practices.

The other options do not accurately describe the concept of tolerant turfgrass. Chemical resistance implies the ability of the grass to resist pesticides rather than pests themselves. Frequent watering does not indicate tolerance to pests; rather, it pertains to the maintenance needs of the grass. An infested turf with weeds wouldn't be considered tolerant, as it suggests that the grass is not competing effectively and is likely suffering from pest or weed pressures. Understanding tolerant turfgrass helps in developing integrated pest management plans that emphasize resilience and sustainability.
