Comparative biological efficiency of some strobilurin-based and triazole-strobilurin-based phytosanitary produscts for the control of some fungal diseases in sunflower crops

The paper presents the results of state testing in the Republic of Moldova of new strobilurin-based phytosanitary products (Arkheon, SC, Netrix 500 SC, and FUN 3 SC) and triazole-strobilurin-based products (Binazol 300 SC, AGFun-10, SC, and FUN 5 SC) against fungi such as Sclerotinia sclerotiorum, Phoma mcdonaldi, Phomopsis helianthi, and Alternaria helianthi, which cause key diseases for sunflower - white rot, phoma, phomopsis, and alternaria. The products subjected to state trials showed sufficiently high biological efficacy to be approved and included as fungicides in the integrated sunflower protection system and in the State Register of Phytosanitary Products and Fertilizers, approved for use in the Republic of Moldova
