Research Comments on Primo Maxx’s Effectiveness
 "In summary, preconditioning plants with Primo Maxx was beneficial for plant survival of extended period of combined drought and heat stress, as manifested by improved turf quality and shoot growth rate under stress conditions. The effects of Primo Maxx on plant tolerance to combined drought and heat stress could be related to its effect on the promotion of photosynthetic capacity associated with increased chlorophyll content and photochemical efficiency, and on the maintenance of cellular hydration. Our results imply that Primo Maxx applications could be utilized as a preconditioning treatment for turf that seasonally experiences heat and drought stress." ⁽¹⁾

 "In summary, our results suggest that the positive effects of Primo Maxx on creeping bentgrass survival in a prolonged period of drought stress were associated with the reduction in water use and increases in osmotic adjustment through solute accumulation, particularly soluble sugars, under the controlled environment conditions." ⁽²⁾
