Integrated pest management
Successful pest management in a commercial vineyard is based on a basic knowledge and understanding of the following.
1) The biology of a grape vine and its annual growth habits.
- Grape growth stages chart
- Vineyard Establishment I: Pre-plant decisions. (E2644)
- Vineyard Establishment 2: Planting and Early Care. (E2645)
2) The biology and life cycle of insects, diseases, nematodes and weeds found in vineyards.
- See our links to identifying insects, diseases, and physiological/chemical disorders.
- Need help identifying an insect or source of pest damage? Contact MSU Diagnostic Services.
- Vineyard scouting calendar for when to look for major pests. Form for scouting vineyards.
3) The environmental conditions favoring pests that injure the crop.
- See our links on weather and climate.
- The use of growing degree days (GDDs) to improve pest management tactics.
- An ecological approach to growing grapes and other fruit: Fruit Crop Ecology and Management
4) The susceptibility of various varieties of grapes to pests and pesticides.
- Order E145PDFGRAPE, the Michigan Grape Management Guide, for information on effectiveness of fungicides and insecticides as well as effects on beneficial organisms.
- Avoiding pesticide resistance
5) The cultural, biological, and chemical control strategies that can be used for optimal production of commercial grapes.
