Abstract: Solid concentrated compositions comprising at least two active substances used in agriculture. The compositions are characterized by being a mixture of concentrated compositions in the form of granules capable of being diluted in water, and in that their content of inhalable particles is less than 0.1%, and preferably less than 0,01%, and in that each granule capable of being diluted in water includes a maximum of one active substance. The invention also concerns a container system comprising such a solid concentrated agrochemical composition in a bag, the wall of which is a water soluble or dispersable material.

Abstract: Tricyclohexyl-tin benzoate and insectidical and/or acaricidal compositions comprising an insecticidally and/or acaricidally effective amount of tricyclohexyl-tin benzoate. Tricyclohexyl-tin benzoate has an excellent acaricidal activity and a remarkable solubility in the usual solvents used in agrochemistry. Because of the high solubility, tricyclohexyl-tin benzoate can be easily formulated in the form of an emulsifiable concentrate.

Abstract: The process for the encapsulation of a liquid hydrophobic substance involves, in a first stage, dispersing an organic phase containing the liquid hydrophobic substance to be encapsulated and at least one polyfunctional hydrophobic monomer having functional groups containing the carbonyl or sulphonyl group, in an aqueous phase containing a polyfunctional amine in which the amine functions have been rendered inactive by salification, and subsequently starting polycondensation by liberating the amine functions through the addition, to the aqueous phase, of an equivalent amount of a base which is stronger than the amine. The process has application to the preparation of compounds which can be used especially in the field of plant health.
