Abstract: The disclosure pertains to bio-active preparations, as solutions, emulsions, suspensions suspoemulsions, emulsifiable concentrates, and dispersible granules where the biologically active compound is dissolved in a solvent the general formula RCH(OR′)2, ketals of the formula R2C(OR′)2, or orthoesters of the formula RC(OR′)3, wherein the substituents are defined herein. Acetal from monoaldehyde and alcohol have the general formula (I) Acetals used herein also include structures such as: And more complex acetal compounds as disclosed herein. The biologically active compounds in such preparations are active organic compounds, in particular, herbicides and safeners, insecticides, fungicides, acaricides, nematicides, pheromones and repellents. Embodiments included are oil-in-water (O/W) emulsions, emulsifiable concentrates(EC), water dispersible granules (WG) and suspoemulsion (SE).

Abstract: The present invention relates to an oil-in-water pesticidal emulsion comprising a lipophilic pesticidal substance, optionally an organic solvent dissolving the said substance, water and an emulsifying system capable of ensuring the dispersion of the oily phase in the aqueous phase, wherein the said emulsion additionally comprises a dispersing agent based on titanium dioxide. The present invention also comprises a suspoemulsion obtained by adding a solid pesticide to the above-mentioned emulsion followed by milling.

Abstract: The present invention relates to stabilized, concentrated or diluted emulsions of the oil-in-water (O/W) type exhibiting a pesticidal activity and to a process for making use of the emulsions. More specifically the invention relates to stable O/W macroemulsions which comprise one or more pesticidal active ingredients in the oil phase or additionally, macroemulsions which comprise one or more pesticidal active ingredients in both the oil and water phases, wherein the oily phase is emulsified or dispersed in the water phase by an emulsifying system; and wherein the emulsions are further stabilized by a solid dispersing agent, namely titanium dioxide, which maintains or improves the emulsion stability. It also relates to a suspoemulsion obtained by milling the said emulsion with an additional solid pesticidal substance.
