Product details
Mode of Action
Copper ions are thought to be passively absorbed by fungal and bacterial spores as they grow. Once absorbed, copper is thought to disrupt the enzyme systems of the pathogenic organisms. Copper Hydroxide is a protectant fungicide and bactericide. Deposits must be on the crop before fungal spores begin to germinate.
Benefits
1. Very good as part of a preventative program in a broad range of crops.
2. giving great preventative protection against fungal diseases.
3. Resistance management for strobilurins and sterol-inhibitors.
Precautions
1. The coverage and protection of copper on the plant surface weathers away due to the new growth of the plant and the weather conditions, hence the importance of re-applications to obtain effective control
2. Plum and peach foliage may be injured, especially at low temperatures.
Environmental Hazards
This pesticide is toxic to fish and aquatic invertebrates and may contaminate water through runoff. This product has a potential for runoff for several months or more after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that contains this product. Drift and runoff may be hazardous to aquatic organisms in waters adjacent to treated areas. For terrestrial uses, do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment wash-waters or rinsate.
