Cím:	Potential dissipation of atrazine in the soil unsaturated zone: A comparative study in four European countries / Salah Issa; Martin Wood; Luc Pussemier; Vincent Vanderheyden; Catherine Douka; Spyros Vizantinopoulos; Zoltan Gyori; Maria Borbely; Janos Katai
Dátum:	1997
Megjegyzések:	A European-wide project has been undertaken to establish the poten- tial for dissipation of atrazine in the soil subsurface environment. Samples were obtained, avoiding contamination, in four countries (Belgium, Greece, Hungary and UK) and laboratory studies carried out. In order to make comparisons between results from each laboratory, a ring experiment was carried out using common methodology for sampling, extraction and analytical techniques. Subsurface materials from each country were distributed to the other coun- tries. Atrazine dissipation was determined in each country for all materials under the same laboratory conditions. The results of this comparative study showed generally good agreement between all laboratories. Signi?cant potential micro- biological dissipation was detected in certain samples. Where diŒerences occurred between laboratories this was attributed to small, spatially heter- ogeneous microbial populations in the subsurface materials

Cím:	Paraffin oil induces resistance against powdery mildew in grapevine through salicylic acid signaling / Pálfi Xénia, Lovas Miklós, Zsófi Zsolt, Kátai János, Karácsony Zoltán, Váczy Kálmán Z.
Dátum:	2021

Megjegyzések:	BACKGROUND: Mineral oils have been widely used in the pest control of several crops. However, their mode of action is poorly understood, especially in the case of their antifungal properties. The possible direct fungicidal activity and the stress-inducing capability of paraffin oil on grapevine were examined using Vitis vinifera L. cv 'Kékfrankos' cuttings and the fungus Erysiphe necator, the causal agent of powdery mildew. RESULTS: Our experiments demonstrated that paraffin oil does not have fungicide activity on E. necator, but induces significant stress-related changes in grapevine physiology. Elevated H2O2 production and the accumulation of the phytohormone salicylic acid were measured. Secondary thickening of the cell wall by lignin deposition and the accumulation of phenolic compounds were also observed. Some enzyme activities related to the detoxification of reactive oxygen species, disease response, and the synthesis of lignin were changed in accordance with the determined changes in cell wall composition and H2O2 levels. CONCLUSION: The results suggest that paraffin oil induces stress responses on grapevine leaves through oxidative burst, and this response is systemized by salicylic acid. The accumulation of lignin and water-soluble phenolics may be directly responsible for the paraffin oil-induced resistance of grapevine against powdery mildew.
