Pesticide composition, application thereof and herbicide

The invention relates to the field of pesticides, and discloses a pesticide composition, applications thereof, and a herbicide, the composition contains a weeding effective amount of a component A and a component B, the content weight ratio of the component A to the component B is 1: (0.5-70), the component A is a compound 168 represented by a formula (I), and the component B is cyhalofop butyl represented by a formula (II); optionally, the composition also contains a component C as shown in a formula (III) which is described in the specification. The pesticide composition and the herbicide provided by the invention can overcome the defect that gramineous weeds such as barnyard grass, moleplant seeds, digitaria sanguinalis and leersia oryzae in a paddy field have resistance to aryloxyphenoxypropionate herbicides such as cyhalofop-butyl, can overcome the defect that phytotoxicity is easily generated to crops such as rice when cyclohexenone herbicides are used for preventing and controlling weeds, have an excellent weeding effect and have very good safety to the crops such as the rice.

Microbial deracemization of α-substituted carboxylic acids: Control of the reaction path

A novel approach to preparing optically active α-substituted carboxylic acids using the whole cells of Nocardia diaphanozonaria JCM 3208 is described. When 2-phenylthiopropanoic acid and 2-methyl-3-phenylpropanoic acid were subjected to the reaction under aerobic conditions, the oxidation reaction proceeded preferentially rather than deracemization of these substrates. Herein, we report the design of reaction conditions to increase the deracemization activity in preference to oxidation reactions. In addition, we have successfully detected a metabolic intermediate in the reaction mixture of 2-methyl-3-phenylpropanoic acid, which indicates that the deracemization is a competitive reaction against the α-oxidation pathway of fatty acid metabolism.

Enantioselective hydrolysis of some 2-aryloxyalkanoic acid methyl esters and isosteric analogues using a penicillin G acylase-based HPLC monolithic silica column

A technique based on liquid chromatography has been developed to facilitate studies of enantioselectivity in penicillin G acylase (PGA)-catalyzed hydrolysis of some 2-aryloxyalkanoic acid methyl esters and isosteric analogues. PGA was covalently immobilized on an aminopropyl monolithic silica support to create an immobilized HPLC-enzyme reactor. Two sets of experimental data were drawn to calculate the enantioselectivity (E) of the kinetically controlled enantiomer-differentiating reaction, the degree of substrate conversion and the enantiomeric excess of the product. The developed enzymatic reactor was coupled through a switching valve to an achiral analytical column for separation and quantitation of the hydrolysis products. The enantiomeric excess was determined off-line on a PGA-chiral stationary phase. In this way, highly precise E values were determined. A computational study related to the hydrolysis of the considered racemic esters was also carried out in order to unambiguously clarify both the substrate specificity and the enantioselectivity displayed by PGA.
