“…Triazoles are sterol inhibiting fungicides. These fungicides have no immediate effect on the respiratory mechanism; therefore, they do not inhibit spore germination (Siegel, 1981) but are effective at preventing mycelial growth (Burlakoti et al, 2010 most effective control of Fusarium species which has been reported by other studies (Gareis and Ceynowa, 1994;Mesterhazy et al, 2003;Burlakoti et al, 2010;Ruan et al, 2011). Active ingredients of Trifidan is triadimenol, (Hall, 1987) showed that triadimenol reduced neither the incidence of infection of crowns by Fusarium nor the incidence of crown rot and Frank and Ayers (1986) and also Everts and Leath (1993) showed that triadimenol provides control of a foliar pathogen which may cause severe yield loss.…”

Tomato (Lycopersicon esculentum) is one of the most widely grown vegetables in the world. There is a growing concern in recent years, both in developed and developing countries, about the use of hazardous fungicides for controlling plant diseases. The in vitro effect of two fungicides commonly used in Algeria namely Trifidan and Antracol (propineb) on the growth of three pathogenic fungi of tomato, Fusarium oxysporum f.sp. radicis-lycopersici, Fusarium commune and Fusarium redolens was investigated to determine the effectiveness of the fungicides in reducing fungi growth. Each fungicide was assayed at 0, 100, 200, 400 and 500 mg L -1 rate in Potato Dextrose Broth (PDB) and incubated at 28°C for seven days. Data were collected on the mycelia weights of the fungi under each treatment. Mycelia weights of the three fungi were significantly reduced at 100 mg L -1 by the two fungicides under antracol treatment F. redolens and F. commune and a significant reduction was observed at 400 and 500 mgL -1 . Application of Trifidan, significantly decrease in mycelia weight of F. oxysporum f. sp. radicis-lycopersici and F. commune irrespective of the rate applied. F. redolens was completely inhibited by Trifidan, and its inhibition started at 100 mg L -1 .

“…For example, El-Kholy (1999) found that the EC50 values of triticonazole were 1.10 and 0.90 µg mL -1 against mycelial growth of R. solani and F. graminearum, respectively. Also, the EC50 values of triticonazole for isolates of F. graminearum ranged from 0.043 to 4.965 µg mL -1 (Burlakoti et al, 2010). Similarly, carbendazim effectively inhibited the mycelial growth and sclerotial production of R. solani at lower concentration (Sriraj et al, 2014;Kumar et al, 2017).…”

“…For example, El-Kholy (1999) found that triticonazole was effective in reducing the Rhizoctonia and Fusarium root rot incidence on wheat plants under greenhouse conditions and increased emergence and plant stands. Burlakoti et al (2010) suggested that triticonazole has the potential to control Fusarium diseases in field conditions if applied in a timely manner. Carbendazim was effective against R. solani at the lowest concentration by maximum inhibiting the mycelial growth and sclerotia formation (Sriraj et al, 2014;Kumar et al, 2017).…”

Application of fungicides is one of the most effective and widely recommended methods of disease control.…”

Root-rot diseases are considered the most serious diseases of wheat in Egypt, causing a considerable loss seed germination, plant stand and grain yield. The present study aims to evaluate the fungicidal activity of four chemical fungicides and two biological control agents. Four fungicides (i.e. triticonazole, carbendazim, carboxin + thiram and metalaxyl M + fludioxonil) and two biological control agents (i.e. Trichoderma harzianum and Bacillus subtilis) were evaluated separately and their compatibility against two pathogenic fungi, Rhizoctonia solani and Fusarium graminearum that causing root rot diseases of wheat. The in vitro studies showed that the fungicidal activity of the tested fungicides against R. solani mycelial growth was descendingly arranged as follows; metalaxyl M + fludioxonil > carbendazim > triticonazole > carboxin + thiram, while it was metalaxyl M + fludioxonil > triticonazole > carbendazim > carboxin + thiram against F. graminearum mycelial growth. In greenhouse trials, the fungicides were applied at 1.5 and 3.0 g kg-1 seeds as seed treatment, while biological control agents were applied at 4.5 and 9.0 x 10 6 spores mL-1 water as soil treatment. The results showed that all the treatments significantly reduced disease incidence and increased emergence and plant stands and the biological control agents were the inferior treatments. Generally, the most effective treatments for controlling root rot diseases were metalaxyl M + fludioxonil followed by carbendazim, triticonazole, while the lowest were carboxin + thiram, B. subtilis and T. harzianum as compared with the control treatment. Moreover, the results concluded that the efficiency of T. harzianum and B. subtilis in controlling R. solani and F. graminearum was obviously enhanced by their compatibility with low rates of the tested fungicides. In conclusion, the biological strategy which used throughout integrated pest management could be improved by using fungicides at low rates.

Fusarium yellows of sugar beet (Beta vulgaris L.) is becoming an important disease in Minnesota and North Dakota in the United States. One of the best ways to manage Fusarium yellows is to develop and use resistant cultivars. Responses of eight sugar beet cultivars to three Fusarium species were determined in the greenhouse and compared to the responses of the same eight cultivars grown in a field already infected by Fusarium yellows. There were significant and appreciable relationships between greenhouse and field studies for responses of eight sugar beet cultivars on Fusarium yellows. The estimated correlation coefficient for area under disease progress curve (AUDPC) between observations in fields and those in greenhouses was 0.987 (p<0.01). The mean AUDPC were significantly different among cultivars (p<0.01) in the greenhouse and in the field studies. Of the cultivars, Van der Have 46177 was the most susceptible, but Crystal R434 the most resistant. Crystal 820, Van der Have 66561, and Beta 4797R were resistant, and Beta 4818R, Seedex Magnum, and Hilleshog 2463Rz were moderately resistant. There was a strong negative relationship between the AUDPC and recoverable sucrose yield in the field experiments and the estimated coefficient of determination was 0.939 (p<0.01). It was concluded that greenhouse screening can act as a useful and reliable means to evaluate and select beet germplasms and/or accessions for resistance to Fusarium yellows.
