training and competency issues

5. How Do You Make an IPM Plan?
 Site assessment – understanding conditions that favour the
pest – unique to your turf area. Map the area to be managed in
the plan
 Monitoring – accurate identification needed of pest, map
specific areas of responsibility for the person monitoring/giving
training
 Setting thresholds – how little/much is acceptable to
staff/golfers
 Identifying management options: cultural, biological, genetic,
chemical how should each one be used and to what degree
 Building weed and street profiles – type of weeds, conditions
that favour it, treatments to get rid of it etc.
 Proactive weed management – actually how you are going to
treat the problem and document work carried out to eradicate
weeds
 Evaluation – monitoring the plan, did the treatments work, can
anything else be done to improve conditions, updating plan

6. Integration in Practice
 Influencing other local
authority departments to
change way of thinking
 Better design will look better
 Prevent detritus – weed
growth and complaints
 Save money less time
 Linked in with targeted and
smart sweeping routes

7. The Weediness Scale
Easy traffic light monitoring for managers & operators
 Use as a measurement tool
 Timing applications
 Timely before seeding
 Catch weeds small – less
chemical, less contamination
 Quicker
 Less complaints
