摘要:
Plant growth regulant compositions comprising as active ingredient a cyanobenzyl(idene) aniline derivative of the following general formula:- wherein A and B either represent hydrogen atoms or jointly represent a C-N covalent bond, each of the substituents X which may be mutually the same or different individually represents a halogen atom, an optionally halogenated alkyl group, an alkoxy or alkanoyl group, or a nitro or carboxyl group and m and n each independently represent 0,1,2,3 or 4. The use of the compositions as plant growth regulants and method for the preparation of the active ingredients.

Compounds of formula: wherein Y is =N- or =CH-, R' and R 2 are alkyl, cycloalkyl or phenyl and Z' and Z 2 are carbonyl or a derivative thereof, or salts or metal complexes thereof. They have fungicidal and plant growth regulating activity.
摘要:
Herbicidal N - (heterocyclicaminocarbonyl)- sulfonamides, and preparation and use thereof, having the general formula wherein R is an aromatic organic group, W is oxygen or sulphur and X and Y are hydrogen, chlorine, bromine, methyl, methoxy or ethoxy. The compounds may be made by reacting 4-aminopyrimidine with an isocyanate or isothiocyanate. They can be formulated for agricultural use with a surface active agent and/or a solid or liquid diluent, and can be used pre- or post-emergence for controlling weeds or for regulating plant growth.
