8. Powdered preparations are dissolved in water at room temperature, but for copper sulfate it is better to use hot water (+40...+50°C).
9. To dissolve biological drugs, filtered or settled water is used.
10. The bushes themselves and the tree trunk circle are carefully sprayed with solutions, since many pests and fungal spores overwinter in the soil.
