Title : Effect of doses of fungicides and plant resistance activators on the control of Rhizoctonia foliar blight of soybean, and on Rhizoctonia solani AG1-IA in vitro development

Authors : Meyer MC, Bueno CJ, Souza NLde, Yorinori JT.
Abstract : Rhizoctonia foliar blight (RFB) of soybean [Glycine max (L.) Merrill] occurs in many tropical and subtropical regions, causing yield reductions of up to 70% and in Brazil, up to 60%. The disease is caused by Rhizoctonia solani AG1-IA and AG1-IB, and by AG2-3 in Japan. RFB occurs in the North, Northeast and Mid-west regions of Brazil. Chemical control remains the only effective method of controlling RFB, but its efficiency depends upon environmental conditions. In this study, 18 fungicides, salicylic acid (SA) and acibenzolar-s-methyl (ASM) were evaluated on R. solani AG1-IA in vitro, by mycelial growth rating and estimating effective concentration for 50% (EC 50) and 90% (EC 90) inhibition of mycelial growth, and in vivo by reduction of disease severity on soybean plants in greenhouse conditions. Mycelial growth was strongly inhibited by the fungicides pyraclostrobin+boscalid and fludioxonil. Preventive fungicide applications were the most effective. Strobilurins were more efficient both in preventive and curative applications. Best results with plant resistance activators were obtained with SA (2.5 mM) sprayed at 20 d before inoculation and with ASM (12.5 mg a.i. l-1) 10 d before inoculation.

Title : Synthesis and fungicidal activity of novel 2-oxocycloalkylsulfonylureas.

Issue : 6
First Page : 2202

Authors : Li XH, Yang XL, Ling Y, Fan ZJ, Liang XM, Wang DQ, Chen FH, Li ZM.
Abstract : A series of 2-oxocycloalkylsulfonylureas (2) have been synthesized in a six-step, three-pot reaction sequence from readily available cyclododecanone, cycloheptanone, and cyclohexanone. Their structures were confirmed by IR, 1H NMR, and elemental analysis. The bioassay indicated that some of them possess certain fungicidal activity against Gibberella zeae Petch. In general, compounds containing a 12-membered ring (2A) are more active than those containing a 6- or 7-membered ring (2B, 2C). In the series 2A, the compounds in which R is a disubstituted phenyl or pyrimidyl showed better activity than those in which R is a monosubstituted phenyl or pyrimidyl, and aryl-substituted compounds have somewhat higher activity than those substituted by pyrimidyl. The further bioassay showed that the representative of 2A, 2A15, has good fungicidal activities against not only G. zeae Petch but also Botrytis cinerea Pers, Colletotrichum orbiculare Arx, Pythium aphanidermatum Fitzp, Fusarium oxysporum Schl. f. sp. Vasinfectum, etc.

Abstract : Twenty-six compounds, derivatives of amides, hydrazines, hydrazides, hydrazones, and semicarbazides, with a 2,4-dihydroxythiobenzoyl moiety, were synthesized from sulfinyl-bis(2,4-dihydroxythiobenzoyl). The compositions and chemical structures of these compounds were confirmed by IR, (1)H NMR, EI-MS, and elemental analysis. Antifungal properties of chemicals under in vitro conditions against five phytopathogenic fungi were estimated. In vivo studies against Erisiphe graminis were also carried out. The compounds N-substituted with an 2,4-dihydroxythiobenzamide group proved to be the most active. N-2-(1-Cinnamylbenzene ester)-2,4-dihydroxythiobenzamide, under in vitro conditions, showed activity at the level of 80-100% development of most pathogens at a concentration of 20 microg/mL and partially at a concentration of 200 microg/mL. For compounds with -HN-NH- or -NH-N= moiety, weak or no fungistatic properties were found at the concentrations studied.

Abstract : Twenty-six compounds, derivatives of amides, hydrazines, hydrazides, hydrazones, and semicarbazides, with a 2,4-dihydroxythiobenzoyl moiety, were synthesized from sulfinyl-bis(2,4-dihydroxythiobenzoyl). The compositions and chemical structures of these compounds were confirmed by IR, (1)H NMR, EI-MS, and elemental analysis. Antifungal properties of chemicals under in vitro conditions against five phytopathogenic fungi were estimated. In vivo studies against Erisiphe graminis were also carried out. The compounds N-substituted with an 2,4-dihydroxythiobenzamide group proved to be the most active. N-2-(1-Cinnamylbenzene ester)-2,4-dihydroxythiobenzamide, under in vitro conditions, showed activity at the level of 80-100% development of most pathogens at a concentration of 20 microg/mL and partially at a concentration of 200 microg/mL. For compounds with -HN-NH- or -NH-N= moiety, weak or no fungistatic properties were found at the concentrations studied.

Abstract : BACKGROUND: A range of botryosphaeriaceous species can cause dieback and cankers in grapevines; however, different species most commonly affect the grapevines in different grape-growing regions and countries. They infect through wounds and sporulate on woody stems and green shoots throughout the year, so wound protection is the recommended control strategy. This research evaluated fungicides for their ability to reduce mycelial growth and conidial germination of three botryosphaeriaceous species and to protect pruning wounds against infection. RESULTS: In vitro experiments showed that nine out of 16 tested fungicides were effective at reducing mycelial growth and/or conidial germination of three isolates each of Neofusicoccum australe, N. luteum and Diplodia mutila. The species differed in their response to the fungicides, although N. luteum was usually the least sensitive. When nine selected fungicides were sprayed on cane pruning wounds on potted and field grapevines and subsequently inoculated with N. luteum conidia, some effectively protected them from infection. The most effective fungicides were flusilazole, carbendazim, tebuconazole, thiophanate-methyl and mancozeb, as they prevented the inoculated pathogen from infecting healthy wood in 100, 93, 87, 83 and 80% of field vines, respectively. CONCLUSION: This research has demonstrated that fungicides applied after winter pruning can protect vines from infection by conidia of three botryosphaeriaceous species.

Abstract : BACKGROUND: A range of botryosphaeriaceous species can cause dieback and cankers in grapevines; however, different species most commonly affect the grapevines in different grape-growing regions and countries. They infect through wounds and sporulate on woody stems and green shoots throughout the year, so wound protection is the recommended control strategy. This research evaluated fungicides for their ability to reduce mycelial growth and conidial germination of three botryosphaeriaceous species and to protect pruning wounds against infection. RESULTS: In vitro experiments showed that nine out of 16 tested fungicides were effective at reducing mycelial growth and/or conidial germination of three isolates each of Neofusicoccum australe, N. luteum and Diplodia mutila. The species differed in their response to the fungicides, although N. luteum was usually the least sensitive. When nine selected fungicides were sprayed on cane pruning wounds on potted and field grapevines and subsequently inoculated with N. luteum conidia, some effectively protected them from infection. The most effective fungicides were flusilazole, carbendazim, tebuconazole, thiophanate-methyl and mancozeb, as they prevented the inoculated pathogen from infecting healthy wood in 100, 93, 87, 83 and 80% of field vines, respectively. CONCLUSION: This research has demonstrated that fungicides applied after winter pruning can protect vines from infection by conidia of three botryosphaeriaceous species.
