A continuous process for preparing microcapsules containing water-insoluble active principles, comprising: (1) preparing, in a first reactor, an aqueous solution containing one or more surfactants, (2) preparing, in a second reactor, a solution comprising at least an active principle immiscible in an aqueous phase and a first component for preparing a polycondensation polymer for forming the microcapsule shell, simultaneously feeding to a tubular reactor of a stream of aqueous solution (1) and solution (2), the ratio of solution (2)/solution (1) being between 0.5 and 2.0, inletting a stream (3) of a second component for preparing the polycondensation polymer into the reactor, wherein stream (3) reacts with the first component, wherein the streams are under turbulent flow conditions in the tubular reactor, and are continuously fed to the tubular reactor, and wherein the ratio between the equivalents of the first component and second component are between 0.9 and 1.1.

The present invention includes compositions and methods of for treating plants infected with fungal pathogens by contacting an infected plant or plant at risk of infection with a fungicidal composition comprising an fungicide selected from copper compound such as copper octanoate or copper hydroxide, or a triazole fungicide such as myclobutanil, propionazoie, tebuconazole or epoxiconazole, an enhancer selected from apyrase inhibitors, e.g., N-(m-toly)-[1,1′-biphenyl]-4-sulfonamide, S-heptyl 2-oxo-2H-chromene 3-carbothioate, 3-(N-(4-bromophenyl) sulfamoyl)-N-(3-nitrophenyl) benzamide, or (E)-3-methyl-N-(1-(naphthalen-2-yl) ethylidene) benzohydrazide and, optionally, a phytologically-acceptable inert carrier.

Non-water-continuous pesticidal microemulsions are described as well as methods of preparing these microemulsions and methods of using these microemulsions to prepare pesticidal application mixtures that are oil-in-water (O/W) macroemulsions. Herbicidal concentrate compositions having a high loading of an auxin herbicide are also described along with methods of preparing these concentrate compositions, and methods of using these concentrate compositions in preparing certain non-water-continuous herbicidal microemulsion compositions. Further, various herbicidal compositions having improved chemical stability and extended residual weed control are described.
