Assays were done under greenhouse conditions in order to evaluate the effect of pyraclostrobin (0.0375, 0.0750 and 0.150 mL.L -1 ) and acibenzolar-S-methyl (ASM) (0.025 g.L -1 ) in common bacterial blight on leaves of snap beans cultivar Bragança. These chemicals were sprayed at three different times: five days before; five days before + five days after; and five days after leaf inoculation with an isolate of Xanthomonas axonopodis pv. phaseoli. They were determinate the levels of polyphenoloxidase, peroxidase and total soluble proteins on inoculated and non-inoculated leaves of snap beans sprayed with pyraclostrobin (0.075 g.L -1 ) and ASM (0.025 g.L -1 ). All concentration of pyraclostrobin and ASM reduced the area under the disease progress curve (AUDPC) on leaves of snap beans, and the least AUDPC value was observed when this products were sprayed five days before + five days after inoculation. Higher levels of polyphenoloxidase, peroxidase and the total soluble proteins were observed on leaves sprayed with pyraclostrobin or ASM.

Os produtos foram pulverizados em três diferentes períodos: cinco dias antes, cinco dias antes + cinco dias após e cinco dias após a inoculação dos folíolos com um isolado de Xanthomonas axonopodis pv. phaseoli. Foram determinados os teores de polifenoloxidase, peroxidase e proteínas solúveis totais em folhas inoculadas e não-inoculadas de feijão-vagem pulverizadas com pyraclostrobin (0,075 g.L-1) e ASM (0,025 g.L-1). Todas as concentrações de pyraclostrobin e ASM reduziram os valores da área abaixo da curva do progresso da doença (AUPDC) e o menor valor da AUPDC foi observado para a aplicação dos produtos cinco dias antes + cinco dias após a inoculação. Altos teores de polifenoloxidase, peroxidase e proteínas solúveis totais foram observados nas folhas pulverizadas com pyraclostobin e ASM.

“…tabaci. Pyraclostrobin also increases TMV resistance in NahG-transgenic tobacco plants (Herms et al 2002), suggesting that this fungicide enhances TMV resistance in tobacco either by acting downstream of SA in the SA signaling cascade or by functioning independently of SA. Pyraclostrobin did not cause the accumulation of SA-inducible PR-1 defense proteins in infiltrated leaves.…”

Infection of plants by necrotizing pathogens or colonization of plant roots with certain beneficial microbes causes the induction of a unique physiological state called "priming." The primed state can also be induced by treatment of plants with various natural and synthetic compounds. Primed plants display either faster, stronger, or both activation of the various cellular defense responses that are induced following attack by either pathogens or insects or in response to abiotic stress. Although the phenomenon has been known for decades, most progress in our understanding of priming has been made over the past few years. Here, we summarize the current knowledge of priming in various induced-resistance phenomena in plants.

“…[15]. In a recent report it was evident that not only fungal diseases, viral disease like TMV infection is also restricted in Tobacco plant pre-treated with pyraclostrobin [16]. Though several fungicides like carbendazim, validamycin and several triazoles like propiconazole, hexaconazole have been recommended for sheath blight disease management but in areas which regularly suffer with severe sheath blight disease, application of any strobilurin fungicides viz.…”

As the usage of fungicides catapulted with the onward march of the dial hour, fungicidal resistance by the pathogens emerged as a new constraint. This amalgamated with the growing demand by the farmers for crop protection agents with low use rates, a benign environmental profile and a low toxicity to human and wild life, further gave an impetus to the search of new molecule of fungicides with novel modes of action. Sheath blight of rice caused by Rhizoctonia solani Kühn is one of the devastating diseases in eastern part of India. Various attempts were taken to develop sheath blight resistant variety but till date no such varieties were released. Various cultural practices combined with use of fungicides are the most common option of managing the disease. Repeated use of same fungicides in the same field sometimes become less or not effective, may be due to development of resistance recombinant of R. solani. Several experiment proved strobilurin based molecules like azoxystrobin, trifloxystrobin, metominostrobin manage the disease effectively and eco-friendly way than other commercially available fungicides.
