Propolis is derived from resinous substances present in the plant tissues of numerous plants including poplar, plum, fir, spruce, chestnut, willow, horse chestnut, oak, ash that the bees collect and partly process with the addition of their own salivary secretions

Bees use propolis as a sealer for hives and to embalm any predatory insects killed after an invasion into the hive. Propolis is lipophilic, hard and brittle at low temperatures but soft, flexible and very adhesive at high temperatures. It has a pleasant aromatic smell and is variable in color, depending on the source of origin.

Among the various constituents of propolis we find: waxes, resins, balsams, essential oils, aromatic acids and polyphenols with a predominance of compounds with a flavonoid, aldehyde, benzoic and caffeic structure; their quantity is related to the plant of origin and the time of harvest. It is harvested from the apiary by scraping it from the points where it was mostly deposited or by stimulating the bees to produce greater quantities through particular beekeeping techniques. In fruit-growing it has been proved that propolis favors the vegetative development of the buds, the functionality of the flower's sexual organs and the setting, as well as the first growth of the little fruit.

Mechanism of action

The propolis in glycolic solution is a natural natural enhancer of the plant defenses extracted, on the apple and pear trees it has a positive action against the carpocapsa and the scab. It is also useful in the prevention of the leaf curl and oidium in peach, and has a synergistic effect when used in combination with sulfur. It carries out a good activity on the gray mold of the various crops and on the olive trees it seems to complete the action of the sodium silicate and limit the damage of the olive fly.


Flavonoid-resinous extract from Propolis in glycol Demineralized water
Minimum content in flavonoids (expressed in galangines) 20 mg / ml


Used on its own
300-500 ml/hl 
As a mixture with fungicide
150-300 ml/hl

Treatments can start from the flowering period to the harvest, every 15-20 days, as necessary.
Most importants treatments are tho ones during flowering period, during the harvest, in case of hail or pest bruises, in mixture with fungicides.
Propoli is used as corroborants on following cultures: apple, pear, peach, apricot, plum, cherry, Kiwi, grapevine, strawberry, Olive, citrus, horticultures, and other small-scale cultivation.


It is preferable to avoid mixtures with products sensitive to glycols.
However, it is good practice to perform a small miscibility test before use.
