IPM/A -13-

during cold and wet weather when turf is semi-dormant
and unable to recover from heavy use.

It is recommended that ail coaches and managers (and
players, if possible) be required to attend one briefing
session on turf care prior to start of the league
season. It is hoped that by educating users of the
fields on the relationship between improper use of the
turf and the establishment of weeds, unnecessary wear

on the turf can be minimized.

I. Spot-renovate areas in athletic fields where
weed populations currently exceed tolerance levels.

_

Renovation of small-to-medium areas of weedy turf can be
accomplished without the use of herbicides by utilizing
the following method. Scalp the existing grass and
weeds off the soil in late winter. A mower set at 1/2
inch or a sod-cutter can be used to accomplish this.
Cultivate the soil shallowly (2") and allow weed seeds
to germinate. Cultivate shaliowly to til] under the
germinated weeds when they are 2” to 3” tall. If the
area is extremely weedy, alTow-a second round of weed
germination to occur and turn weeds under. This process
reduces the supply of weed seeds jn the germination zone
and gives newly-sown grass seed a competitive edge.
