Metyltetraprole is a new quinone outside inhibitor (QoI) fungicide showing potent activity against QoI-resistant fungi that possess the G143A cytochrome b mutation, which confers resistance to existing QoIs such as trifloxystrobin. For its sustainable use, monitoring of metyltetraprole sensitivity is necessary and the establishment of appropriate methodol. is important in each pathogen species. In Cercospora beticola, the causal agent of sugar beet leaf spot, some isolates were less sensitive to metyltetraprole (EC50 > 1 mg L-1, higher than the saturated concentration) using the common agar plate method, even with 100 mg L-1 salicylhydroxamic acid, an alternative oxidase inhibitor. However, microtiter tests (EC50 < 0.01 mg L-1), conidial germination tests (EC50 < 0.01 mg L-1) and in planta tests (>80% control at 75 mg L-1 run-off spraying) confirmed that all tested isolates were highly sensitive to metyltetraprole. For trifloxystrobin, G143A mutants were clearly resistant upon microtiter plate tests (median EC50 > 2 mg L-1) and distinct from wild-type isolates (median EC50 < 0.01 mg L-1). Notably, mycelium fragments were usable for the microtiter plate tests and the test was applicable for isolates that do not form sufficient conidia. Our monitoring study by microtiter plate tests did not indicate the presence of metyltetraprole-resistant C. beticola isolates in populations in Hokkaido, Japan. The microtiter tests were revealed to be useful for monitoring the sensitivity of C. beticola to metyltetraprole and trifloxystrobin. To complete the study, the researchers used N,2-Dihydroxybenzamide (cas: 89-73-6) .
N,2-Dihydroxybenzamide(cas: 89-73-6) can be used:To prepare phenylboronic acid-based bioconjugates for chromatographic applications;As a ligand to synthesize Fe(III), Cu(II), Ni(II) and Zn(II) complexes.Quality Control of N,2-Dihydroxybenzamide
