In a previous post, I stated short term pains for long term gains and that was related to allowing the annual bluegrass weevil to eat some of the poa in the fairways since we are using growth regulators to help eliminate the poa. The photos show the 12th fairway about 8 days ago when the eating was at its peak and the bottom photo shows the same fairway yesterday. The bentgrass is beginning to fill in the voids where the poa is. Had we applied an insecticide on the entire course to take out the larvae, it would have cost us close to $9,000. Plus, all the beneficial insects that are in the soil may have been effected as well. Instead, we spot seeded these areas at a cost of $250 and made an extra urea and potassium app at a cost of $500 to help get the bentgrass to fill in. While the area is not perfect, it will be in the coming weeks and has had little impact on playability. Next year, we will have less poa to worry about on this and many other fairways.
