Scab


Punctuation is a disease of fungal origin, which mainly affects garden plants, manifesting itself with dark spots, often very common all over the foliage; the spots are round, of varying size, and may also affect the fruits of the pome fruits. The affected leaves tend to fall, causing a constant deterioration of the plant.
This fungus tends to hibernate in the ground in the form of spores and has a greater development during the cooler periods of the year, therefore from the end of winter to the first warm springs and towards the end of summer and autumn and winter.


Scab: Care and prevention of scab


Punctuation tends to particularly affect species and varieties that are particularly sensitive to this fungus, especially if the specimens present in our garden are weak or not very luxuriant; therefore surely upstream the choice of varieties resistant to this disease and a correct cultivation can prevent scab infestation, or at least contain it.
A strong preventive action is exercised, at the end of winter by copper-based wetting, to be carried out at intervals of 12-15 days, avoiding the flowering period; from flowering on, sulfur-based wetting is carried out, which will affect the entire foliage of the plant; these types of treatments are carried out only when the climate is still mild, and the maximum temperatures do not reach 25-28 ° C. Copper and sulfur can also have a healing effect, also preventing the fungus from spreading over the entire foliage; these products are also suitable for autumn bathing, on the foliage still infested by scab.
Fundamental is the action of removal of diseased leaves, from the plant and also from the ground: leaving the leaves on the ground we will allow the fungus to winter in our garden, to then find it in the first warm; therefore in autumn we carefully remove all the sick foliage, even the one that has already fallen, and burn it, to prevent the fungi from emitting spores into the soil.
