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 thegeneral 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). The bio-active/acetal formulations provide enviro-safe treatments as formulated herbicides, safeners, insecticides, fungicides, acaricides, nematicides, pheromones and repellents and exhibit low flammability and biodegradibility.
