摘要:
The phytotoxic action of too high a concentration of peroxygen compounds such as peroxycarboxylic acids and hydrogen peroxide in the combating of phytopathogenic microorganisms, such as fusaria, in the water systems of plant irrigation systems, especially greenhouses, can be eliminated. The water is treated with a peroxycarboxylic acid solution which is brought in contact with a solid decomposition catalyst for active-oxygen compounds before the water is used for irrigation, in order to reduce the content of peroxycarboxylic acid and hydrogen peroxide. The water contacts and flows through a fixed bed of decomposition catalyst, by trickling over it or flowing through the conduits of a monolithic block coated with a decomposition catalyst such as platinum, palladium or rhodium.

摘要:
The invention relates to optically active isomers of trans-3-(2-chloro-2-(4-chloro-phenyl)-vinyl-2,2-dimethyl-cyclopropane-1-carboxylic acid .alpha.- cyano-4-fluoro-3-phenoxy-benzyl ester of Formula (I), to methods for the preparation of said optically active isomers, to compositions containing said optically active isomers and to the use of said optically active isomers and compositions for their ectoparasiticidal activity.
摘要:
The new compound ##STR1## is prepared and converted to the new acetal ##STR2## which is reacted with an alkali phenolate or alkaline earth metal phenolate in the presence of copper or a copper compound as a catalyst and in the presence of a diluent at a temperature between about 100.degree. and 200.degree. C. to produce the new acetal ##STR3## which can be hydrolyzed to the corresponding aldehyde which is a known intermediate for pyrethroid-like insecticides.
