Active substance

Ferrous sulfate - 53%.


In the spring, treatment with iron sulfate slows down the awakening of plants, retards the opening of the kidneys, and this is more a disadvantage than dignity. In addition, iron sulphate may leave burns on new shoots and young leaves, so care should be taken with the recommended concentrations. For these reasons, iron sulfate is better to use in the fall. And in the spring to choose drugs containing copper - copper sulphate, Bordeaux mixture, Oxyh and others

The effectiveness of iron sulfate as a fungicide is also controversial - the drug has a surface effect and does not get inside the plants. Spraying on the trunks do not give an absolute guarantee for the destruction of pathogens of fungal diseases. Spores can persist in places behind the bark where the drug does not fall, and the disease continues to develop.

Foliar spraying is carried out with a 0.05-0.1% solution (5-10 g per 10 l of water). A solution of the same concentration is suitable for prophylactic spraying.
The period of protective action is 14 days.


Iron sulfate is incompatible with lime and preparations containing it (Bordeaux fluid); with pure copper sulphate, giving a solution of high acidity, as well as with insecticides and preparations that decompose in an alkaline medium. After the application of ferrous sulfate to the use of these funds should take at least 1.5-2 months, and the air temperature should reach positive values.
