The effectiveness of the alternating treatments with an appropriate systemic fungicide and 1% solution of MKP was similar to that of the commercial treatment with the systemic fungicides alone. However, application of the systemic fungicides only, omitting the phosphate treatment when they were scheduled, was significantly less effective than either the phosphate or the alternation treatments. These results indicate that the use of phosphate fertilizer has a significant role in disease control, enabling up to 50% reduction with number of fungicide treatments required for powdery mildew control. These results were confirmed in a large-scale demonstration ...","PeriodicalId":9607,"journal":{"name":"Canadian Journal of Plant Pathology-revue Canadienne De Phytopathologie","volume":"20 1","pages":"253-258"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74528738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using soft-ripe fruits, all 12 fungicides reduced brown rot relative to the water check after 7 days incubation, with tebuconazole and flusilazole being numerically superior. Using firm-ripe fruits, five sterol-inhibiting fungicides and iprodione reduced brown rot infections after 7 days incubation, with tebuconazole, flusilazole and myclobutanil being numerically superior. Fruits were soaked for 4 min in suspensions of tebuconazole and flusilazole at 33, 67, and 100 mg a.i./L, and incubated for 7-8 days.

The critical micellar concentration (CMC) of viscosin was 4 𝛍g/mL in a 2 mM phosphate buffer (pH 7.0), and the surface tension was reduced from 71 mN/m to 25 mN/m. When broccoli florets were immersed in viscosin solutions of increasing concentration, the tissues became wetted at 10 𝛍g/mL and electrolytes were induced to leak at a concentration between 10 and 25 𝛍g/mL. Erythrocytes were lysed at concentrations of 10 𝛍g/mL and above. Since membrane effects occurred above the CMC, it appears that viscosin does not act as a membrane toxin, but rather as a nonspecific detergent. A viscosin deficient mutant, induced by Tn5 mutagenesis, caused decay of wounded florets only, but the decay failed to spread to adjacent nonwounded florets as had occurred with a wild strain. When the mutant strain (1 x 107 cfu/mL) was incubated with viscosin (25 𝛍g/mL), it was...","PeriodicalId":9607,"journal":{"name":"Canadian Journal of Plant Pathology-revue Canadienne De Phytopathologie","volume":"74 1","pages":"296-303"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79976448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fiftyseven North American isolates of PVYN were screened using this assay and one, originating from garden potato tubers in Ontario, was found to be positive. This isolate was confirmed to induce the diagnostic PTNRD, using a panel of 20 potato cultivars. AC Chaleur, AC Novachip, Century Russet, Cherokee, and Frontier Russet reacted severely and developed PTNRD either at the time of harvest or during storage. About 800 tubers collected from New Brunswick and Prince Edward Island fields, from plants exhibiting mosaic and leafroll symptoms were also screened for various strains of PVY using PCR primers.

Corn (Zea mays), lady's finger (Ahelomoschus esculentum), cowpea (Vigna unguiculata), and the partially resistant tomato line CL1131-0-0-43-4 (CL1131) were rotated with susceptible tomato in different combinations. The susceptible tomato cultivar Pusa Ruby was used as an indicator plant to assess wilt severity (percent leaves wilted) in each plot after rotation. Wilt severity was significantly (P < 0.05) reduced by rotation with corn, lady's finger, cowpea, or resistant tomato compared with continuous tomato. The onset of bacterial wilt was delayed by 1-3 weeks and wilt severity was reduced by 20-26% when susceptible tomato was grown after corn, lady's fingers, cowpea or resistant tomato.
