The importance of pest and disease monitoring
Monitoring is key to minimising pest damage through timely action to avoid loss and maximise effectiveness at the right grapevine phenological stage. The below pest and disease calendars are a guide to when pests and diseases are likely to be present and impactful in WA vineyards. Critical for pest management is identifying the time pests are most likely to be present in a susceptible stage such as newly emerged nymphs or the start of a breeding cycle.
