Věchet, Lubomír
Conference proceedings on biological plant protection. Contributions were presented on the influence of biological seed dressing for wheat on the composition of soil micromycetes, efficacy of botanical insecticides based on seed oil from Pongania glabra Vent. against Plutella xylostella L. larvae, supressive effect of selected plant species on the germination and foliar necrosis, induced resistence of wheat to powdery mildew.

Induced resistence of wheat to pokery mildew (Blumeria graminis f. sp. tritici)
Věchet, L. ; Šerá, Božena ; Vrchotová, Naděžda ; Kolomazník, K.
Inducers of chemical, biological - plant origin and animal origin were used to inducing of wheat resistance to powdery mildew. The best effect had benzothiadiazol (BTH)inducer of chemical origin. From biological inducers ginger and giant knotweed, from animal origin the sample 2 had the best effect. The latest effective on decrease powdery mildew severity had the sample 4 from inducers of biological inducers it was curcuma.
Mode of action of resistance inducers against powdery mildew in wheat
Grigová, Vendula ; Šašek, M. ; Věchet, L. ; Burketová, Lenka
One of the method, how to increase resistance of plants against disease without changes of their genom is use of phenomenon known as induced resistance. Plant protection in system of induced resistance is based on activation of defence mechanisms of plants by stimulation of methabolic and structural changes in plants. For induction of resistance is used many compounds of chemical and biological origin. This work informs about mode of action of inductors used in pathosystem wheat (Triticum aestivum L.) – powdery mildew (Blumeria graminis f. sp. tritici). Efficiency of cited inducers were analysed by means of markers genes expression and by finding out infective structures of Blumeria. Slight expression of WCI5 (wheat chemically induced gene) ) and WCK1 (gene encoding a MAP kinase in wheat) was detected. Test of germinability showed that BTH (benzothiadiazol) treatment and treatment of oak bark extract caused an inhibition of germinative activity of Blumeria graminis spores on wheat.
