FIELD: agriculture.
SUBSTANCE: invention relates to the agriculture. Fungicidal composition for apple tree protection against scab is an aqueous solution containing iron sulphate in concentration of 1.7–2.2 %, calcium hydroxide, magnesium oxide hydrate solution, ammonia solution in ratio of components of 1:0.15:0.25:0.03 to 1:0.2:0.35:0.05 and solution pH 6.5–8.0. Processing is performed before blossoming.
EFFECT: invention increases fungicidal effect, reduces cauterizing action of iron vitriol on vegetative organs of plants, and also due to presence of magnesium and ammonium cations to stimulate growth and development of plants.
