fludioxonil

Fludioxonil (CGA 173506), a phenylpyrrole fungicide, inhibits the growth of B. cinerea from strawberry and blackberry crops.

Fludioxonil (Standard) is the standard substance of Fludioxonil, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Fludioxonil (CGA 173506), a phenylpyrrole fungicide, inhibits the growth of B. cinerea from strawberry and blackberry crops.

Boscalid is a broad-spectrum carboxamide fungicide that inhibits fungal respiration by binding to the ubiquinone site of mitochondrial complex II/succinate dehydrogenase.1It suppresses mycelial growth ofS. minorby 87 to 100% and ofS. sclerotiorumby 77 to 100% when used at a concentration of 1 μg/ml.2In field studies, boscalid applied at 5.6 μg/cm2provides 55.5 and 30.4% disease control for lettuce drop caused byS. minorandS. sclerotiorum, respectively. It decreases cell viability of mouse primary cortical neurons following long-term exposure but is not cytotoxic (LC50= >100 μM for acute and continuous exposure). Formulations containing boscalid have been used in agriculture to prevent fungal growth on crops. 1.Wang, Y., Duan, Y., Wang, J., et al.A new point mutation in the iron-sulfur subunit of succinate dehydrogenase confers resistance to boscalid in Sclerotinia sclerotiorumMol.

Fludioxonil is employed to manage the growth of axillary buds (suckers) following the topping of tobacco plants. Its mode of action includes a localized systemic effect, contact action, and phytotoxicity.

Pyraziflumid is a fungicide. Pyraziflumid is a novel member of succinate dehydrogenase inhibitor fungicides (SDHI). The average EC50 value was 0.0561 (±0.0263)μg/ml for mycelial growth. There was no cross-resistance between pyraziflumid and the widely used fungicides carbendazim, dimethachlon and the phenylpyrrole fungicide fludioxonil.
