Eyespot is one of the most important fungal diseases of the stem base of wheat (Triticum aestivum L.). The presented study clearly demonstrated that the Pch1 gene was the main effective source for reducing the eyespot disease score in the analyzed winter wheat lines. Nevertheless, Pch1 was present only in 8−9% of the investigated lines. Using an isoenzymatic marker and molecular markers, the presence...
Eyespot can reduce yields, even up to 50%. There are four genetically characterized resistances in wheat varieties, controlled by: (1) the Pch1 gene, transferred from Aegilops ventricosa; (2) the Pch2 gene, originating from wheat variety Capelle Desprez; (3) the Pch3 gene, originating from Dasypyrum villosum; and (4) the Q.Pch.jic-5A gene, a quantitative trait locus (QTL) located on chromosome 5A...
This paper describes a HPLC method with DAD detection for determining a mixture of four trichotecenes B in wheat protected by fungicides. The recoveries of trichotecenes B from wheat treated at two levels of fortification: 0.2 and 0.6 mg/kg for NIV, DON, 15-AcDON and 3-AcDON were: 101.83; 75.78; 84.58; 75.19 and 71.17; 70.24; 87.83; 74.95, respectively. The results confirmed usefulness of this method...
The aim of conducted research was the comparison of using full (registrated) doses of fungicides and doses indicated by decision support system (PC-Plant Protection) in protecting winter wheat against diseases. In the experiment were studied two fungicidal programs – each one in four protection strategies: in standard dates of treatments using recommended doses, in standard dates using reduced by...
Ekologiczna uprawa roślin zbożowych nie daje szerokiej możliwości stosowania środków, które mogą być pomocne w zwalczaniu wielu grzybów chorobotwórczych. Asortyment dopuszczonych do stosowania środków grzybobójczych w gospodarstwach ekologicznych ciągle się zmniejsza i jest niewystarczający. Wykorzystanie już dostępnych metod, zarówno agrotechnicznych jak i środków pochodzenia naturalnego, w celu...
