In this study, a novel succinate dehydrogenase inhibitor (SDHI) fungicide benzovindiflupyr was found to have strong inhibitory activity against gray mold caused by Botrytis cinerea. The sensitivity of B. cinerea to benzovindiflupyr was determined by testing 103 pathogen isolates with mean values of 2.15 ± 0.19 mg L–1 and 0.89 ± 0.14 mg L–1 for mycelial growth and spore germination inhibition, respectively. Furthermore, benzovindiflupyr had excellent long-lasting protective activity. Unfortunately, there were positive correlations between benzovindiflupyr and boscalid (r = 0.3, P = 0.04) and between benzovindiflupyr and isopyrazam (r = 0.31, P = 0.04). In the field, cucumber flowers are susceptible to infection by B. cinerea. Benzovindiflupyr applied at 20 mg L–1 by dipping flowers could successfully control cucumber gray mold, with the benzovindiflupyr dose of dipping flower application less than 1% of that of spraying application. Benzovindiflupyr combined with dipping flower application showed significant control of gray mold.

新型SDHI杀菌剂Benzovindiflupyr结合合理的浸花方法有效控制灰霉病
在这项研究中，发现一种新型的琥珀酸脱氢酶抑制剂（SDHI）杀真菌剂苯并乙烯基二氟吡草对灰葡萄孢引起的灰霉病具有很强的抑制活性。通过检测103株病原体的菌丝生长和抑制孢子萌发的平均值分别为2.15±0.19 mg L –1和0.89±0.14 mg L –1来确定灰葡萄孢菌对苯并文菲的敏感性。此外，苯并乙烯基二氟草醚具有优异的持久保护活性。不幸的是，苯并乙烯基双氟吡咯与boscalid之间存在正相关（r = 0.3，P = 0.04），而苯并乙烯基双氟吡咯与异吡嗪之间存在正相关（r = 0.31，P= 0.04）。在田间，黄瓜花易受灰质双歧杆菌感染。通过浸花以20 mg L –1的浓度施用苯佐文地氟吡草能够成功控制黄瓜灰霉病，浸花的苯并文地氟草酯剂量不到喷施剂量的1％。Benzovindiflupyr结合浸花施用显示出对灰霉病的显着控制。
