Integrating nitrogen source and application timing into the management of large patch on zoysiagrass
… the field, summer nitrogen applications without tebuconazole had the highest disease severity in all seasons of the study. Spring and/or fall nitrogen applications did not increase large patch severity, and spring fertility was most consistent with decreased large patch severity. Similar to the …

Effects of chitosan oligosaccharide-amended fungicide treatments on the control of fusarium head blight in wheat
… in combination with site- specific fungicides (tebuconazole, metconazole, pydiflumetofen, and thiophanate- methyl), for FHB management and reduction of DON levels in wheat grains. In greenhouse trials, FHB severity was assessed at 8-, 11-, 14-, 17- and 20-days post inoculation. Then, the area …

Crop manipulation to improve hybrid radish seed yield and quality : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
… trinexepac- ethyl at 150 and 300 ml a.i/ha, tebuconazole at 0.8 and 1.6 litres a.i/ha and mepiquat chloride at 305 g a.i/ha. The latter was applied in the seedling stage. Plant height and stem length were reduced by some treatments, but all the PGRs increased stem thickness. Seed yield was …

Control of fusarium head blight in wheat: I. Evaluation of host plant resistance and fungicides II. Molecular markers associated with QTL for resistance
… that fungicides containing the active ingredient tebuconazole are very effective in reducing losses caused by FHB. While fungicides can be a useful tool for FHB suppression, they do not provide complete control, and their efficacy is greatly affected by timing. Planting cultivars that are …

Studies on the chemical control of Fusarium ear blight of winter wheat (<i>Triticum aestivum</i> L.)
The fungicides prochloraz and tebuconazole (at concentrations of 2 µg ml<sup>-1</sup> ) were shown to reduce the mycelial growth of <i>Fusarium culmorum, F. avenaceum, F. poae, F. graminearum and Microdochium nivale in vitro</i> by over 90 % compared to the untreated control. In addition, …

Fungicide Sensitivity of Erysiphe necator and Plasmopara viticola from Virginia and nearby states
… EC50 of sensitive subgroup) was highest for tebuconazole (360) and myclobutanil (350), followed by triflumizole (79), triadimefon (61), and fenarimol (53). Sensitivities to all five DMI fungicides, but also azoxystrobin, were moderately to strongly correlated (pairwise r-values ranging from …

Incidence and Management of Seed Transmission of Cylindrocladium Black Rot of Peanut in Virginia
… treatment fungicides indicated that fludioxonil, tebuconazole, and thiram may offer the best protection against disease spread from seed transmission of <i>C. parasiticum</i>.

Investigating Novel Approaches for the Integrated Control of the Soilborne Strawberry Pathogens Macrophomina phaseolina and Fusarium oxysporum f. sp. fragariae
… rates for subsequent <em>in planta</em> studies. Tebuconazole strongly inhibited the mycelial growth of both pathogens (average EC<sub>75</sub> for <em>Mp</em> was 2.4 ppm; average EC<sub>75</sub> for <em>Fof</em> was 7.48 ppm), as did metconazole (average EC<sub>75</sub> for <em>Mp</em> was2.53 …

Chitosan oligosaccharide: use to control Fusarium head blight and to reduce deoxynivalenol accumulation in wheat grains
… used. When applied in seed treatment, both tebuconazole and chitosan oligosaccharide reduced the incidence of F. graminearum and preserved the germination potential of seeds when inoculated with the fungus. In general, there was no significant reduction in disease severity between doses or …

Utilizing spring dead spot mapping to assess precision management strategies, topographical epidemiology, economic opportunities
… not cost-effective with annual applications of tebuconazole due to its low cost per application. These findings suggest that adopting precision treatment methods with appropriate fungicides can reduce costs and improve sustainability in SDS management. Together, these studies highlight the …

Integrated Approach to Understanding Tomato Sour Rot and Improving Disease Management on the Eastern Shore of Virginia
… and postharvest treatments. Propiconazole and tebuconazole completely inhibited growth of all colonies. Cultivar trials were conducted to determine if resistance or tolerance to G. candidum occurs. Ten commonly grown round and Roma cultivars on the ESV were similarly susceptible to G. candidum, …

Molecular techniques for studying <i>Fusarium</i> ear blight of wheat
… trials (1994/5-1996/7). Prochloraz and tebuconazole significantly decreased both visual symptoms of FEB and fungal DNA content of <i>F. culmorum</i> and <i>F. poae</i> ear blight of wheat. Overall, both fungicides appeared equally effective, although the efficacy ofthese fungicides was …
