Sustainable agriculture program manager Keith Pekin has urged Swan Valley vineyard owners to apply spray applications in a bid to curb the scourge of diseases, such as powdery mildew.
‘We had wet weather combined with high humidity well into spring and those conditions can cause diseases in vineyards,’ he said.
‘Powdery mildew is a danger for vineyards because fungus spreads over the upper and lower surfaces of the leaves of plants.
‘It is important for spray applications to be used, which can be effective to combat the diseases. It is important for sprays to be used properly.
‘Sprays should not be used when winds are strong because it could impact on people in the vicinity,’ he said.
‘There are also new technologies available, which improve environmental practices in regards to spraying.’
