STRATEGIES AND
TACTICS OF NEMATODE MANAGEMENT
Rev
01/01/20
- Assessment of the situation
- Sampling to determine presence, absence and
abundance of key species
- Determining host status of intended or current
crops
- Population levels in relation to economic
thresholds
- Avoidance of the Nematode Problem
- Selection of biogeographic area
- Selection of planting site
- Selection of planting date
- Selection of planting stock
- Exclusion of Problem Nematodes
- Inspection, certification, quarantine
- Treatment of infected plant material
- Restriction of spread – people, equipment,
animals, water, wind
- Grower and public education
- Eradication, Reduction or Management
- Cultural practices, environmental manipulation
