They are classified as being of implausible non-thermal nature due to low quantum energy and low specific absorption rate levels, even if considering worst cases of "hot spots" of only millimeter size. The considerations of this paper demonstrate that classical theory of polarization offers a conventional interpretation for all three the existence of so far unclarified effects, their low reproducibility and their low intensity. The basis of this explanation is given by the assumption that hot spots contain even hotter “nano spots” on a molecular level according to well known mechanisms of γ-relaxation. In this paper, the concept is put for discussion assuming a heterogeneous system that consists of water molecules as well as larger-sized functional molecules. A consistent interpretation through temperature increase on the level of nanometer sized molecular compounds promises to favor interdisciplinary discussions with respect to safety regulations.展开更多

The inhibitory effects of different pesticides against early leaf spot have not been analyzed systematically. Based on screening of Cercospora arachidicola Hori in earlier period, the inhibition rates of different pesticides on C. arachidicola growth were studied, and pesticides with strong inhibitory effects against C. arachidicola were screened. The paper provided a reference for field imitation test.展开更多
