Abstract. Innovative solutions in the decisive control of pests and elective
treatments to stimulate agricultural production will accomplish the need to
feed a growing global population and the long-term toxicity of synthetic
fungicides. The product development is
based on indigenous potential of natural antifungal compounds (eg vegetable
extracts from fenugreek and marigold, tomato glycoalkaloids, etc.) as well as
on circular bio-economy - obtaining protein hydrolysates from tannery waste. In
this economic niche context, an innovative bio-fungicide and bio-stimulator
prototype was created, with enhanced effectiveness through the profile and
ratio of the associated active compounds, with an extended spectrum of action,
GLYCAM-STIM Combo. The impact of two variants of biopesticide was compared to
the commercial ecological product Serenade, on strawberries - Premial variety.
It was investigated the development of gray rot - Botrytis cinerea and the
effect on the production and quality of the fruits. The results demonstrate the
limitation of the frequency of the attack and its intensity, the increase of
fruit firmness and mass (by 8g) and the production’s rise by 7t/ha. The data
confirm the applicability’s extension of the multifunctional biopesticide also
at the level of the strawberry species, as well as in the protection of cherry
orchards. The research was carried out within the project BIO-PLANT-PROTECT 262
/ 2021.
