Under the scorching rays of the sun, the solution quickly evaporates from the surface of the leaves, and the preparations lose their effectiveness. After rain, a thin film of water remains on the leaves, which reduces the effect of active substances and the concentration of the solution.
3. Processing is carried out strictly after the spring pruning of the bushes. Spraying additionally protects the cut points.

7. The prepared solutions are passed through a filter so that microparticles do not clog the spray holes.
8. Powder preparations are dissolved in water at room temperature, but for copper sulfate it is better to use hot water (+ 40 ... + 50 ° С).
9. Filtered or settled water is used to dissolve biological preparations.
10. The bushes themselves and the trunk circle are carefully sprayed with solutions, since many pests and fungal spores winter in the ground.
11. If, after spraying with a contact insecticide, it immediately rains, the treatment is repeated the next day. This rule does not apply to systemic drugs. The active substances penetrate into plant tissues in the first 2-3 hours after treatment.

Gardeners recommend not to increase the chemical load on the plant and take a break 5-7 days between fungicide and insecticide treatments.
