Application of product

Preparation of the product for use
Fill the spray tank with one-quater of the necessary quantitiy of water. While stirring continuously, add a measured quantity of the product.

For the treatment of pome and stone fruit trees an usprayed buffer zone of 30 m wide from the border of water bank  1st and 2nd order, should be considered. To protect aquatic organisms in the treatment of olives, buffer zone of 16 m width from the border of water bank 1st and 2nd order shoud be considered. For the treatment of vine 15 m width buffer zone from the border of water of 1st order and 10 m width from border of water of 2nd order. For the treatment of tomatoes and potatoes 15 m width buffer zone from the border of water of 1st order and 5 m width from border of water of 2nd order.
