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 : PCR-RFLP detection of the E198A mutation conferring resistance to benzimidazoles in field isolates of Monilinia laxa from Greece
Year : 2012
Volume : 39

Last Page : 17
Authors : Malandrakis AA, Markoglou AN, Ziogas BN.
Abstract : Sensitivity to benzimidazoles in isolates of the brown rot pathogen (Monilinia laxa) collected from stone fruit in central and northern Greece was evaluated and the molecular basis for resistance was investigated. M. laxa isolates were classified as benzimidazole – sensitive (S) or highly resistant (HR) based on their sensitivity profiles to carbendazim. Thirty seven percent of the isolates belonged to the HR phenotype, carried no apparent fitness penalties and exhibited resistance factor values (based on EC50 values) greater than 500. Highly resistant isolates were also less sensitive to the benzimidazoles benomyl and thiophanate-methyl but more sensitive to the N-phenylcarbamate diethofencarb and the benzamide zoxamide compared to isolates belonging to the S phenotype. Fungitoxicity tests with fungicides belonging to other chemical classes revealed no cross resistance relationships between benzimidazoles and the dicarboximide iprodione, the phenylpyrrole fludioxonil, the hydroxyanilide fenhexamid, the carboxamide boscalid, the triazole tebuconazole and the strobilurin-type fungicide pyraclostrobin, indicating that a target site modification is probably responsible for the resistant phenotypes observed. Comparison of the β-tubulin gene DNA sequences between resistant and sensitive isolates revealed a point mutation resulting from the E198A substitution of the corresponding protein in all HR isolates tested. An Eco31I restriction site in the β-tubulin gene, which was destroyed in HR M. laxa isolates, allowed the development of a PCR-RFLP diagnostic for the detection of the E198A resistance mutation.

Thirty seven percent of the isolates belonged to the HR phenotype, carried no apparent fitness penalties and exhibited resistance factor values (based on EC50 values) greater than 500. Highly resistant isolates were also less sensitive to the benzimidazoles benomyl and thiophanate-methyl but more sensitive to the N-phenylcarbamate diethofencarb and the benzamide zoxamide compared to isolates belonging to the S phenotype. Fungitoxicity tests with fungicides belonging to other chemical classes revealed no cross resistance relationships between benzimidazoles and the dicarboximide iprodione, the phenylpyrrole fludioxonil, the hydroxyanilide fenhexamid, the carboxamide boscalid, the triazole tebuconazole and the strobilurin-type fungicide pyraclostrobin, indicating that a target site modification is probably responsible for the resistant phenotypes observed. Comparison of the β-tubulin gene DNA sequences between resistant and sensitive isolates revealed a point mutation resulting from the E198A substitution of the corresponding protein in all HR isolates tested. An Eco31I restriction site in the β-tubulin gene, which was destroyed in HR M. laxa isolates, allowed the development of a PCR-RFLP diagnostic for the detection of the E198A resistance mutation.

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.

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.

Title : Efficacy and effects on yield of different fungicides for control of wet bubble disease of mushroom caused by the mycoparasite Mycogone perniciosa

Abstract : Carbendazim, iprodione, prochloraz-Mn, thiabendazole and thiophanate-methyl were tested in vitro and in vivo for their effect on Mycogone perniciosa, the mycoparasite that causes wet bubble disease of white button mushroom. In vitro experiments showed that prochloraz-Mn (ED₅₀ = 0.006-0.064 μg ml⁻¹) and carbendazim (ED₅₀ = 0.031-0.097 μg ml⁻¹) were the most effective fungicides for inhibiting the mycelial growth of M. perniciosa, while iprodione (ED₅₀ = 1.90-3.80 μg ml⁻¹) was the least effective. The resistance factors calculated for the five fungicides were between 1.4 and 2. The results obtained suggest that there is very little risk that M. perniciosa will develop resistance to the fungicides assayed. The in vivo efficacy of fungicides for control of wet bubble was studied in two mushroom cropping experiments, which were artificially infected with two doses of M. perniciosa, 10⁶ and 10⁷ spores m⁻², respectively. There was, in the low dose inoculum experiment, a very high degree of effectiveness (96.5-100.0%) with all the fungicides assayed. However, iprodione performed poorly (20.5-24.4%) compared with the other fungicides (88.7-100.0%) in the high concentration inoculum experiment. The most effective treatments for controlling wet bubble did not improve the biological efficiency of Agaricus bisporus.

Abstract : Fenhexamid is a hydroxyanilide fungicide with excellent performance against Botrytis cinerea but also effective against Monilinia spp. which cause brown rot disease in apple and stone fruit. A total of 75 Monilinia laxa field isolates were utilized to determine baseline sensitivity while a number of fenhexamid-resistant laboratory mutants were used to evaluate the resistance risk associated with the longevity of the effectiveness of fenhexamid. Fenhexamid was found to be highly effective against all field isolates. EC50 values ranged from 0.02 to 1 μg mL−1 and were distributed unimodaly around an average of 0.1 μg mL−1. M. laxa laboratory strains with moderate and high resistance levels to fenhexamid were isolated after UV mutagenesis. All fenhexamid-resistant strains showed parental sensitivity to carbendazim, iprodione, fludioxonil, pyraclostrobin, flusilazole and prochloraz. Interestingly, some of the mutant strains were also resistant to tridemorph, fenpropimorph and spiroxamine. Studies on fitness parameters of fenhexamid-resistant strains revealed a fitness cost on sporulation and pathogenicity but not on mycelial growth. These results suggest that fenhexamid should be a good alternative site-specific fungicide for the control of brown rot disease caused by M. laxa. However, appropriate anti-resistance strategies should be considered to ensure the successful commercial use of fenhexamid in the long run.

Abstract : BACKGROUND: Succinate dehydrogenase inhibitors (SDHIs) constitute a fungicide class with increasing relevance in crop protection. These fungicides could play a crucial role in successful management of grey mould disease. In the present study the effect of fluopyram, a novel SDHI fungicide, on several developmental stages of Botrytis cinerea was determined in vitro, and the protective and curative activity against the pathogen was determined on strawberry fruit. Furthermore, fungal baseline sensitivity was determined in a set of 192 pathogen isolates. RESULTS: Inhibition of germ tube elongation was found to be the most sensitive growth stage affected by fluopyram, while mycelial growth was found to be the least sensitive growth stage. Fluopyram provided excellent protective activity against B. cinerea when applied at 100 µg mL(-1) 96, 48 or 24 h before the artificial inoculation of the strawberry fruit. Similarly, fluopyram showed a high curative activity when it was applied at 100 µg mL(-1) 24 h post-inoculation, but, when applications were conducted 48 or 96 h post-inoculation, disease control efficacy was modest or low. The measurement of baseline sensitivity showed that it was unimodal in all the populations tested. The individual EC(50) values for fluopyram ranged from 0.03 to 0.29 µg mL(-1). In addition, no correlation was found between sensitivity to fluopyram and sensitivity to other fungicides, including cyprodinil, fenhexamid, fludioxonil, iprodione, boscalid and pyraclostrobin. CONCLUSIONS: The obtained biological activity, baseline sensitivity and cross-resistance relationship data suggest that fluopyram could play a key role in grey mould management in the near future and encourage its introduction into spray programmes.
