Rough Bluegrass is Checking Out

With the air temperatures in the high 80's/low 90's and soil temperatures at a 2-inch depth of close to 80°F, rough bluegrass (Poa trivialis) is now going dormant on athletic fields, home lawns and golf courses. Rough bluegrass is a cool-season grass best adapted to growing in air temperatures of 60-75°F and soil temperatures of 50-65°F. Once temperatures get hot (usually end July/mid-August) in central Ohio, rough bluegrass goes dormant/brown until more favorable weather returns.

What are Succinate Dehydrogenase Inhibiting (SDHI) Fungicides?

To start succinate dehydrogenase is an enzyme complex which is a catalyst for reactions that occur in the mitochondria. Succinate dehydrogenase (SDH) is also referred to as succinate-coenzyme Q reductase (SQR) or respiratory Complex II but in all cases the term refers to an enzyme complex. Succinate dehydrogenase plays a role in both the Krebs cycle and electron transport where most of the energy is derived from aerobic respiration. Interestingly, if something happens where SDH enzyme malfunctions (a mutation occurs) it sends a signal out of low oxygen. At this point SDH, which plays a role in tumor suppression, ceases to suppress.

Fall Coring

Autumn cultivation season has started for some with much of the coring targeted around Labor Day. Of the golf course management practices, core cultivation (aerification) is probably the most noticeable to golfers, and the least appreciated. The disruption to play is quite obvious but the benefits, although not as visual are just as important. Aggressive coring practices are normally done during periods of active turfgrass growth in the spring and fall. Factors involved in the type of coring to be done (hollow versus solid, tine diameter and depth, degree of disruption to the turf) are dependent on the desired long-term outcomes. Listed below are some of the outcomes from coring (and various types of cultivation practices).
