1. Pest and disease monitoring


A pest is any organism that reduces the availability, quality or value of a human resource. Most organisms in vineyards are non-pests, some can be occasional (or potential) pests, but the main problems are key pests, which cause significant damage every season unless some management action is taken. Many key pests are parasites where the host/parasite relationship has become unbalanced. Using appropriate methods for monitoring pest and disease levels in vineyards provides the basis for managing them. Managing them in a considered manner, through the establishment of action thresholds and subsequent control strategies, will reduce waste and reliance on agro-chemicals, improve crop productivity, and support the economic viability of the vineyard.

Pest management programmes should include:

  • A means of monitoring pests and factors that influence their development
  • An assessment of the level of damage at which intervention is required
  • The assessment of risks to the operator and environment of available control methods
  • The implementation of all available methods of control in an effective and coordinated fashion
  • The monitoring of effectiveness of control methods used
Best Practice
A.

Use weather based forecasting methods for disease prediction.

Best Practice
B.

Monitor the vineyard area for insect, mite and disease pests twice a week during the growing season and keep a written record as part of a pest management programme.

Best Practice
C.

Establish action thresholds that consider the potential damage to the crop, cost of control methods and value of production.

Minimum Standard
D.

Weekly monitoring of pests and diseases is undertaken to assess the risk of damage in relation to the development stage of crop and local weather conditions.
