CROP PRIORITIES
Pests, diseases and growing conditions can produce similar symptoms. Connect field history and diagnosis with the crop stage before choosing an input.
Botrytis bunch rot can reduce marketable fruit and harvest quality. Follow flower and cluster condition, berry injury and wet-weather risk. Canopy ventilation, fruit hygiene and crop-specific protection should work together, with particular attention to susceptible cultivars and dense clusters.
View biological products →Discuss this crop challenge →Powdery mildew affects leaves, shoots and berries, with fruit scarring reducing market quality. Monitor early canopy symptoms and local disease forecasts; canopy management and a preventive protection programme should follow crop use and disease pressure. Biological protection requires particular attention to timing and its place within the wider programme.
View biological products →Discuss this crop challenge →Uneven vine growth can reflect root-knot, dagger or other nematodes, depending on the region and site. Root damage may resemble water or nutrient stress. Root and soil diagnosis should guide rootstock selection, planting-material health and the management plan; a single nematode category does not describe every vineyard.
Discuss this crop challenge →THROUGH THE SEASON
From establishment to harvest or renewal, the purpose of crop management changes with each stage.
Early growth depends on root condition and stored resources. Set product priorities around the vineyard’s actual needs.
Flowering management balances canopy growth, nutrition and the developing crop. Keep the purpose of each product clear.
Berry development brings specific mineral-nutrition and environmental-management questions. Product selection should distinguish those two needs.
After harvest, review seasonal performance and the condition of roots and leaves to inform the next cycle.
BIOLOGICAL INPUTS
These products have distinct roles in nutrition, root development and crop management. For a pest or disease, product selection also requires evidence for the identified target and applicable market label.
