Phytotoxicity
During the blooming period spraying is not recommended. On peach, plum and copper-sensitive apple and pear varieties, the product may be toxic for the plants if applied when vegetation is in full growth: in such cases, use is not recommended. On less known species of vegetables, flowers and ornamentals is recommended to test the product on a small surface before using the product on a large surface.

For ornamental, flowers and cypress PHI is not needed.

REI – Re-entry interval
Workers are allowed to enter on treated surface when the spray mixture is dry, using of personal protective equipment (long pants, long sleeve shirts) and gloves are mandatory. Worker exposure is limited to 6 hours per day in apple orchard and to 4 hours per day in orchards of other fruit crops.

Preparation of the product for use
Fill the spray tank with one-quarter of the necessary quantity of water. While stirring continuously, add a measured quantity of the product. Fill the spray tank with the rest of water and stir until the use of spray mixture. Application must be done in calm, windless weather to avoid spray drift. Remains of the spray mixture is diluted with water in a ratio of 1:10 and sprayed on already sprayed surface. At dosing, mixing, loading and spraying we take good agricultural practice in to account.

Worker exposure control
When handling with concentrated mixture, mixing, loading and cleaning the tank, during the spraying with tractor mounted sprayer or spraying with backpack sprayer (vertical or horizontal spraying) personal protective equipment is mandatory (protective clothing, gloves and protection for eyes/skin). In contact with sprayed plants personal protective equipment is mandatory to use (long pants, long sleeve shirts).

Mixing (compatibility):
Cuprablau Z 35 WG is compatible with most commonly used fungicides and fertilizers. However, the fungicide cannot be mixed with pesticides that cause a high acid or basic reaction. When preparing the mixture each plant protection product (PPP) must be loaded separately to the tank (mixture must be well mixed before loading next PPP). If no more particular instructions exist, an individual PPP is added (in measured quantity) in the following order in to a tank:  wettable PPP (wettable powder-WP, wettable granules-WG); water soluble concentrate (SL), suspension (SC, CS); emulsions (oil in the water, emulsifiable concentrate). For additional advice you should ask the producer.

Environmental exposure controls (Buffer zone)
During the application, it is necessary to prevent contamination of the watercourses, wells, lakes and springs in order to comply with water protection regulation. For the safety of aquatic organisms, treatment of small fruits, flowers, ornamentals, tomato and cucurbits an unsprayed buffer zone of 15 m wide from the border of water bank 1st and 2nd order should be considered. For the safety of aquatic organisms, treatment of loquat an unsprayed buffer zone of 20 m wide from the border of water bank 1st and 2nd order should be considered. For the safety of aquatic organisms, treatment of kiwifruit an unsprayed buffer zone of 30 m wide from the border of water bank 1st and 2nd order should be considered. For the safety of aquatic organisms, treatment of stone fruits, pome fruits, olives, citrus, mulberry and nuts an unsprayed buffer zone of 40 m wide from the border of water bank 1st and 2nd order should be considered. For the safety of aquatic organisms, treatment of cypress an unsprayed buffer zone of 50 m wide from the border of water bank 1st and 2nd order should be considered. For the safety of aquatic organisms, treatment of other crops an unsprayed buffer zone of 15 m wide from the border of water of 1st order and 5 m width from border of water of 2nd order, should be considered.

WARNING
When using Cuprablau Z 35 WG or other copper-based products, the number of applications may be reduced, so that annual quantity of pure copper on the same field does not exceed 4 kg of pure copper per ha.

MAXIMUM RESIDUE LEVELS
Maximum residue levels for copper active ingredients are in accordance with the Regulation (EC) No. 396/2005 of the European parliament and of the Council of 23th February 2005 on the maximum levels of pesticide residues in or on food and feed of plant and animal origin and amending Council Directive 91/414/EEC.
