摘要:
An aqueous agrochemical composition and in particular an agrochemical concentrate comprises (a) a non-encapsulated aqueous solution or dispersion of an agrochemical and (b) a suspension in said aqueous solution or dispension of a microencapsulated liquid, water-insoluble, bioperformance-enhancing adjuvant for said agrochemical. The adjuvant suitably has little or no surfactant properties. The invention permits oil adjuvants such as “Turbocharge” and “Brij 92” to be built into agrochemical compositions with which they would normally be incompatible. With certain adjuvants reduced phytotoxicity may be observed.
摘要:
3-Isochromanone is prepared by partially chlorinating o-tolylacetic acid with sulphuryl chloride or chlorine gas in an inert organic solvent in the presence of a free radical initiator. The 2-chloromethylphenylacetic acid first obtained is converted to 3-isochromanone by treatment with a base and separated from unreacted o-tolylacetic acid, which is in the form of a salt, by a phase separation technique. The separated o-tolylacetic acid salt is converted to o-tolylacetic acid by controlled acidification and the o-tolylacetic acid is extracted for re-use. The invention reduces the formation of unwanted, over-chlorinated by-products and leads to a more efficient process.

The novel compounds have plant-protective properties and are suitable for protecting plants against infestation by phytopathogenic microorganisms, in particular fungi.
摘要:
Stabilized liquid agrochemical compositions are provided that comprise flowable, aqueous dispersion concentrates comprising a) a continuous aqueous liquid phase; b) at least one dispersed, solid phase comprising a dispersion of polymer particles having a mean particle size of at least one micron, wherein the outside surfaces of the particles comprise a colloidal solid material and wherein the particles have at least one agrochemically active ingredient distributed therein, optionally a non-porous particulate mineral that acts as a diffusion barrier to slow the release of the active ingredient, and optionally at least one non-cross-linkable mobile chemical such that the extraction of this chemical from the disperse phase renders it porous in a manner that allows the active ingredient to diffuse out. The colloidal solid is used to stabilize the polymenzable resin in an emulsion state during preparation.
摘要:
Stabilized liquid agrochemical compositions are provided that comprise flowable, nonaqueous dispersion concentrates comprising a) a continuous non-aqueous liquid phase; b) at least one dispersed, solid phase comprising a dispersion of polymer particles wherein the outside surfices of the particles comprise a colloidal solid material and wherein the particles have at least one chemical agent distributed therein. The colloidal solid is present in an amount effective to stabilize the polymer particles in an emulsion state during the process which is used to prepare the dispersed phase. When the chemical agents are agriculturally active ingredients, the compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators.
摘要:
The present invention relates to methods for generating polymeric particles which comprise one or more active ingredients. The invention also relates to the use of such polymeric particles as a seed treatment. The present technology provides an improved seed treatment suitable for applying plant propagation materials. The seed treatment of the present technology includes the use of high aspect-ratio particles as a seed treatment. The present technology has been found to have advantageous properties associated with the seed treatment including increased adherence of the formulation to the seed and reduced tendency to dust off.
摘要:
This invention relates to agrochemical compositions comprising a benzamide compound of formula (I) where R 1 is fluoro, methoxy or C 1-4 alkyl; R 2 and R 3 are each independently optionally substituted C 1-6 alkyl or optionally substituted C 2-6 alkenyl; or R 3 is hydrogen and R 3 is optionally substituted C 5-8 alkyl or optionally substituted C 4-6 alkenyl or optionally substituted benzyl; or R 2 and R 3 and the nitrogen atom to which they are both attached together form an optionally substituted 5-, 6- or 7-membered ring, which ring optionally contains at least one further heteroatom selected from O, N and S; to the use of those benzamide compounds as solvents; to certain novel compounds of formula (I); and to a process for preparing those novel compounds.

A product comprising microcapsules which themselves comprise (a) a polymeric shell; and (b) a core comprising an agrochemical which has a melting point greater than or equal to 25ºC characterised in that the agrochemical is dispersed as a solid in a hydrophobic material which has a melting point greater than or equal to 25ºC but which does not exhibit a glass transition temperature.
摘要:
An adjuvant suitable for use with a lipophilic agrochemical has the formula (I), R1-(CO)m-O-[-R2O-]n-R3, wherein R1 is a C16 to C20 straight or branched chain alkyl or alkenyl group, R2 is ethyl or isopropyl, n is from 8 to 30 and m is 0 or 1 and when R2 is ethyl, R3 is a C1 to C7 alkyl group and when R2 is isopropyl, R3 is hydrogen or a C1 to C7 alkyl group, provided that when R1 is oleyl, R2 is isopropyl and R3 is hydrogen, n is not 10. An adjuvant composition comprising an agrochemical and an adjuvant of formula (I) is also claimed. Adjuvants of the invention show effective bioperformance enhancement despite having little or no surfactant properties.
