Solid and liquid pesticidal concentrate and spray compositions are described which exhibit enhanced efficacy due to the addition thereto of a compound which increases EPSPS enzyme inhibition by the pesticide, cell membrane permeability, or expression of hydroxyproline-rich glycoproteins.

Pesticide compositions containing dicarboxylic acids

A method of improving the yield and vigor of agronomic plants, in particular leguminous plants such as soybeans, involves treating such plants and/or the propagation material of plants with a composition that includes an active agent, such as a fungicide, that has no significant activity against fungal plant pathogens of the treated plant. When the plant is not wheat, a preferred agent of this type is 4,5-dimethyl-N-(2-propenyl)-2-(trimethylsilyl)-3-thiophenecarboxamide (silthiofam). Plants and plant propagation material, such as seeds, that have been treated by the novel method are also described.

Method of improving yield and vigor of plants

The compounds may be formed by the reaction of bis-(phosophonomethyl)urea or urea respectively with carbon monoxide and formaldehyde in the presence of a carboxymethylation catalyst precursor and solvent.

A process for the continuous production of N-(phosphonomethyl)glycine is provided. In the process, N-(acetyl)iminodiacetic acid is formed in an amidocarboxymethylation reactor system. The N-(acetyl)iminodiacetic acid product stream is either: (1) reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid; or (2) deacylated and cyclized to form a 2,5-diketopiperazine, and then reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid. In either case, the N-(phosphonomethyl)iminodiacetic acid product is recovered and converted to N-(phosphonomethyl)glycine.

The selected sequence-directed hydrolysis of RNA under physiologically relevant conditions is described using conjugates comprising metal complexes covalently linked to oligodeoxynucleotides as hydrolysis agents. The oligodeoxynucleotide portions of the agents are selected to provide molecular recognition via the Watson Crick base pairing to the target RNA sequence to be hydrolyzed. A method is described for determining the RNA hydrolysis effectiveness of metals and ligands used to form the metal complexes useful in this invention.

A hydroxydiphenylamine compound can be converted to an N-phenylquinoneimine by reacting the hydroxydiphenylamine with oxygen or an oxygen containing gas in the presence of a modified activated carbon catalyst, the catalyst having had surface oxides removed therefrom.

Preparation of N-phenyl-benzoquinoneimine from hydroxydiphenylamines

Process for the preparation of an N-acyl amino carboxylic acid by means of a carboxymethylation reaction. In this reaction, a reaction mixture is formed which contains a base pair, carbon monoxide, hydrogen and an aldehyde with the base pair comprising a carbamoyl compound and a carboxymethylation catalyst precursor. In a preferred embodiment, the carbamoyl compound and aldehyde are selected to yield an N-acyl amino carboxylic acid which is readily converted to N-(phosphonomethyl)glycine, or a salt or ester thereof.

A process for the production of N-(phosphonomethyl)iminodiacetic acid. N-(acetyl)iminodiacetic acid is formed in a amidocarboxymethylation reactor system, into which a source of each of the following is continuously fed: (1) acetamide or an acetamide derivative, (2) formaldehyde or a formaldehyde generator or derivative, (3) a carbonylation catalyst, (4) carbon monoxide, and optionally (5) hydrogen. In turn, an amidocarboxymethylation reaction product stream, which contains N-(acetyl)iminodiacetic acid and the carbonylation catalyst, is withdrawn from the amidocarboxymethylation reactor system. The carbonylation catalyst is separated from the amidocarboxymethylation reaction product stream to recover the carbonylation catalyst and form a catalyst depleted product stream which contains N-(acetyl)iminodiacetic acid. The separated carbonylation catalyst is returned to the amidocarboxymethylation reactor system, and the N-(acetyl)iminodiacetic acid in the catalyst depleted product stream is either: (1) reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid; or (2) deacylated and cyclized to form a 2,5-diketopiperazine, and then reacted with a source of phosphorous and a source of formaldehyde in the presence of an acid to form a phosphonomethylation reaction product stream containing N-(phosphonomethyl)iminodiacetic acid and acetic acid. Either way, the N-(phosphonomethyl)iminodiacetic acid is precipitated from the phosphonomethylation reaction product stream in the presence of acetic acid, and the precipitate is recovered to form a filtrate stream.

Process for preparing substituted aromatic amines

A method and apparatus to continuously measure the ratio of gasses in a binary gas mixture. A binary gas mixture is passed through a chamber in which a single ultrasonic wave travels from one piezoelectric transducer to another on the opposite side of the chamber. Immediately upon sensing an incoming ultrasonic wave, the transducer on opposite side of the chamber converts into a transmitter and transmits a single wave on top of the just received wave. The new wave travels back in the direction of the first transducer where it is received. The time of travel back and forth through the chamber is compared to a reference time, and represents the concentration of a gas in a binary gas mixture. The difference between time of travel in the direction of flow and against the direction of flow represents standard flow rate. A temperature sensor located in the middle of the chamber is used to temperature compensate the result. From the measured times, the temperature, the offset, and stored formulas a microprocessor calculates the gas concentration and/or the standard flow rate for the gas.
