“…In other researches, many other authors stated a 22-72% reduction of the DON content, while using the prothiconazole + tebuconazole fungicide mixture (Homdork et al 2000;Hart et al 2001;McMullen et al 2001;Lechoczki-Krsjak et al 2008). The results of our trial showed an even greater decrease of the DON content.…”

“…Such conditions lower the quality of wheat, which results in a lower thousand-grain weight and a higher percentage of fine, scabby and coloured grains. Various studies showed that FHB can be efficiently controlled by using the prothiconazole + tebuconazole fungicide mixture, which can reduce the DON content by 22-72% (Homdork et al 2000;Hart et al 2001;McMullen et al 2001). Miedaner (2012) stated that contamination can be reduced by 50-70%, while the DON content in grains can be lowered by 50-80%.…”

The effect of spraying speed (5, 8.5 or 12 km/h) on deposition quality of fungicide on a winter wheat head, yield, grain quality, occurrence of Fusarium head blight (FHB) and deoxynivalenol (DON) content in grains was investigated in 2011 and 2012. Asymmetric double flat fan air-injector nozzles were used in the trial at a spraying pressure of 5.0 bars. A prothiconazole + tebuconazole fungicide mixture was used for spraying. An increase of spraying speed significantly lowered coverage values at the front and rear parts of a wheat head. At all three spraying speeds, the rear part of a wheat head reached a better coverage value. The effect of spraying speed was significant in 2011, when the 5 km/h spraying speed generated a significantly higher grain yield and a significantly higher thousand-grain weight in comparison with the other treatments. In both trial years, the lowest grain yield occurred on the unsprayed control. In 2011 and 2012, the latter also reached the lowest hectolitre weight and thousand-grain weight. In both trial years, the unsprayed control had a significantly higher DON content than the other treatments. In 2012, the DON content on the unsprayed control exceeded the allowed maximum level. The spraying speed did not affect the DON content in the grains. The effect of spraying speed was also noted in the FHB incidence. A significantly lower FHB incidence occurred at the 5 and 8.5 km/h spraying speeds.

“…To overcome this problem, pesticide application has been an important way to improve wheat yield. TEB and TBM are two commonly used pesticides in wheat field, and they play an important role in controlling diseases and weeds (Homdork et al, 2000;Mukherjee et al, 2015). Besides, the dissipation studies of TEB and TBM in wheat and soil have been widely investigated in previous couple of years.…”

In practice, pesticides are usually simultaneously applied or one after another for crop protection. This often leads to a coexistence of pesticide mixtures in soil. One of the most important processes influencing the behavior of a pesticide in the environment is its degradation and adsorption in soil. Thus, the degradation and adsorption behaviors of tebuconazole (TEB) and tribenuron-methyl (TBM) alone and combined application in wheat soil (pH 7.28) were studied. The concentrations of TEB and TBM in soil were determined using a quick, easy, cheap, efficient, rugged and safe method (QuEChERS) with ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). Results showed that TEB has longer half-lives compared with TBM in the tested soils when they were applied individually. The degradation of TEB was markedly affected by concentration and soil microorganisms. In the non-sterilized soil, half-lives of 0.8 and 80 mg kg -1 TEB were 16.4 and 69.3 d, respectively, and half-lives of 0.8 and 80 mg kg -1 TEB were 20.4 and 73.5 d in the sterilized soil, respectively. The degradation of TBM was not affected by TEB in both soils; however, TBM could reduce the degradation of TEB. Compared to TEB alone, the rates of degradation of 80 mg kg -1 TEB in presence of 32 mg kg -1 TBM were reduced 15.9% and 18.2% in non-sterilized and sterilized soils, respectively. Soil adsorption affinity of TEB was significantly higher than TBM. When used combined, adsorption capacity of TEB was not affected by TBM. However, the adsorption of TBM was obviously inhibited in presence of TEB.

“…Head infection, yield, yield components and the percentage of Fusarium-infected grains were determined in many studies connected with FHB (Homdork et al 2000). With the development of chemical methods, the assessment of plant resistance to fusa rium head blight started to be supplemented with chemical analyses, which facilitated the determination of mycotoxin concentrations in grain (Kubo et al 2014).…”

The aim of this study was to determine the profile of fungal metabolites and antioxidant substances from plants on a representative population of wheat cultivars grown in Poland. Tests were conducted on grain of 23 wheat cultivars in three experimental variants: natural infection (control), chemical crop protection, and artificial inoculation with the fungi F. graminearum and F. culmorum. Grains were analysed in terms of infection rate, mycotoxin, ergosterol, free and bound phenolic acid content, as well as antioxidant capacity. Calculated Fusarium head blight index (FHB index) ranged from 0% to 24% in the control, from 0% to 95% after inoculation and from 0 to 3% following chemical crop protection treatments. The highest concentration of ergosterol was detected in seeds from inoculated plots, with a mean value of 26.69 mg/kg. The highest mean concentration calculated for total toxin content was recorded after inoculation (7.833 mg/kg). The mean value for ferulic acid for inoculated samples resulted 2574 mg/kg, while for chemically protected samples 1158 mg/kg was obtained.Based on of discriminant analysis genotypes can be separated for inoculation 100%, for chemical crop protection 95%, and for natural infection 90%. Amongst 12 analysed phenolic acids the highest discrimination power was found for gallic acid, 4-hydroxybenzoic acid and vanillic acid.
