1

Advantages and disadvantages of monocultures

Advantages:
- Mechanisation
- Competition - none from other plants
- Needs of specific grape - tended to. Maximise yields, minimise costs.

Disadvantages:
- More disease prone (treatments/protection)
- Natural ecosystem - none there to replenish nutrients (fertilizers needed)
- Environmental damage - from residual chemicals in air/ground

2

Disadvantages of pesticides and mineral fertilizers

- Harmful to soil quality
- Expensive
- Bad for environment and health
- Less consumer, grower desirability
- Legislation

3

Characteristics of Conventional viticultrue

- Mechanisation
- Chemical inputs
- Irrigation
- Clonal selection
- Intensive fruit farming with monocultures
- Reduce labour, raise production.

4

Lutte Raisonee

* Integrated Pest Management
- Set thresholds for action (i.e pest population)
- Identify pests and monitor
- Preventative measures (boost vines own defense mechanisims)
- If thresholds exceeded and preventative failed - examine alternate control options

5

Advantages and disadvantages of sustainable viticulture

* Advantages
- More attention to economic, social, commercial impact
- Reduction in treatments (also cost saving)
- Scientific approach to minimise intervention

* Disadvantages:
- Not a protected term
- Where high uptake, nationwide standards too low (New Zealand)

6

Most effective use of precision viticulture

To control treatment and irrigation

7

Advantages and disadvantages of precision viticulture

Advantages:
- Detailed understanding of variations
- tailor wide range of interventions to single blocks/rows
- improve quality

Disadvantages
- Initial cost (data collection, sensors, trained staff to interpret & intervene)

8

What key things should be considered when establishing a vineyard

- Site selection
- Soil preparation
- Planting material
- Nutrient management
- Water management
- Canopy management
