The present invention relates to a method for controlling undesirable vegetation in an aquatic environment in which a rice plant is growing. In the method of this invention, a herbicidally effective amount of pendimethalin or of a composition comprising pendimethalin is applied to the aquatic environment before emergence of the undesirable vegetation and after germination of the rice seedlings. The method is particularly suitable for weed control in flooded rice fields.

Compositions for improving plant health, the compositions comprising at least one water-soluble pesticide and at least one non-herbicidal water-insoluble agrochemical, are described. Also described are processes for preparing the compositions and methods of improving agronomic crop plant health using the compositions.

The present invention relates to a composition comprising microcapsules, which comprise a polyurea shell and a core, wherein the core comprises a water-insoluble pesticide and the shell comprises a polymerization product of a tetramethylxylylene diisocyanate, an cycloaliphatic diisocyanate, and an aliphatic diamine; to a method for preparing the composition comprising the steps of contacting water, the pesticide, the tetramethylxylylene diisocyanate, the cycloaliphatic diisocyanate, and the aliphatic diamine; and to a method of controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition is allowed to act on the respective pests, or the crop plants to be protected from the respective pest, on the soil and/or on undesired plants and/or on the crop plants and/or on their environment.

An agricultural chemical composition comprises a solvent having the general formula CO(OR.sub.a)(R.sub.b), wherein R.sub.a is a linear or branched alkyl group of one to eight carbon atoms and R.sub.b is an aromatic group. Active agricultural components are dissolved in the solvent to produce a solution usable for distributing the active components.
