Abstract

Background: Clusterbean [Cyamopsis tetragonaloba (L.) Taub] commonly known as ‘guar’ means ²cow food² is an annual arid and semi-arid legume crop belonging to the family leguminaceae. Methods: Two field experiment were conducted during 2019-2021 to find out the most effective fungicide for the management of Alternaria leaf blight in Cluster. Seven fungicides viz., Tebuconazole 250 EC @ 0.1%, Difenconazole 25 EC @ 0.1%, Hexaconazole 5 EC @ 0.1%, Propiconazole 25 EC @ 0.1%, Chlrothalonil @ 0.2%, Trifloxystrobin 50% WG@ 0.1%, Mancozeb 75% WP @ 0.2% were evaluated for their efficacy aganist cluster bean Alternaria blight. Result: In the year 2019 during Kharif season the foliar spray with Tebuconazole 250 EC @ 0.1% was found to be the most effective fungicide at initiation of flowering and at pod stage with minimum disease severity (9.87 and 12.00%) and the maximum seed yield and straw yield of 2077 and 3994 kg/ha, respectively. During Kharif-2020 same trends was observed with Tebuconazole 250 EC @ 0.1% in reducing the severity of the disease foliar spray of Tebuconazole also recorded the highest B: C ratio of 4:5 and 4.73 during 2019-20 and 2020-21 respectively.

应用杀菌剂防治集束豆叶枯病

背景:杂豆类[Cyamopsis tetragonaloba (L.)]通常被称为“瓜尔”，意思是“牛食”，是一种一年生的干旱和半干旱的豆科作物，属于豆科。方法:在2019-2021年进行2次田间试验，寻找防治稻瘟病最有效的杀菌剂。采用替布康唑250 EC @ 0.1%、地芬康唑25 EC @ 0.1%、六康唑5 EC @ 0.1%、丙环康唑25 EC @ 0.1%、氯菌灵@ 0.2%、氟虫酯50% WG@ 0.1%、代森锰锌75% WP @ 0.2%等7种杀菌剂对集豆疫病的防治效果进行了评价。结果:2019年秋收季节，喷施戊唑唑250 EC @ 0.1%是开花期和荚果期最有效的杀菌剂，病害严重程度最低(9.87和12.00%)，种子产量和秸秆产量最高，分别为2077和3994 kg/ha。在kharif2020期间，施用Tebuconazole 250 EC @ 0.1%降低病害严重程度的趋势相同，在2019- 2020和2020-21期间，Tebuconazole叶面喷雾的B: C比值最高，分别为4:5和4.73。
