Application of biological products at cultivation of garden pea Pisum sativum l.

Abstract

The possibilities of using the biological products “Trichodermine” (Trichoderma viride Pers ex Fr.), “Gliocladine” (Gliocladium virens Miller et al.) and the mycorrhizal activator “Rhizo VAM Basic” (Glomus intraradices Schenck&Smith) for control of fungal diseases in garden pea and and their impact on the biometric indicators of young plants were studied. Biological preparations based on antagonistic fungi Trichoderma viride and Gliocladium virens improve the phytosanitary condition of the plants, the mycorrhizal fungus Glomus intraradices stimulates the formation of the root system and tuber formation, but has a weak fungicidal effect against Fusarium wilt in this culture. The experiment was performed on an artificial infectious background by Fusarium oxysporum Schlecht. f. sp. pisi (Hal.) Raillo, isolated from diseased plants. The effect of application of the biological products“Trichodermine” and “Gliocladine” is 34-68%, from “Rhizo VAM Basic” - 8% compared to the infected control. The combined application of biological preparations with fungicidal and mycorrhizal action significantly protects the crop from infection with the causative agent of Fusarium wilt of garden pea.
