A method for modulating the release rate of microencapsulated active ingredients comprising the following steps: I) preparation of an aqueous suspension A) comprising microcapsules of at least one active ingredient, II) preparation of a liquid emulsifiable in water, component B), comprising a solvent of the active ingredient and at least a surfactant, III) water, component C), for diluting to the application dose the active ingredient, and mixing A), B) and C).

Method for modulating the release rate of microencapsulated active ingredients

The present invention provides a formulation characterised by the simultaneous presence in cyclodextrin based supramolecular complexes, of two components, one of which is a neonicotinoid selected from the group consisting of Thiacloprid and Thiamethoxam and the other possesses an activity synergistic with the first, enhancing its effectiveness. The synergistic component that is able to synergistically enhance the activity of the active principle is piperonyl butoxide, and. Processes for preparing said formulation and its use for the activities herein indicated are further aspects of the present invention.

Biologically active formulation

The present invention provides a formulation characterized by the simultaneous presence in cyclodextrin based supramolecular complexes, of two components, one of which possesses insecticidal, acaricidal, fungicidal, snailcidal or vermicidal activity and the other possesses an activity synergistic with the first, enhancing its effectiveness. The biologically active substance is chosen from the following classes of chemical products: carbamates, organophosphates, thioureas, pentatomic or hexatomic heterocycles in which 1, 2 or 3 nitrogen atoms are present. The synergistic substance can be chosen from components containing at least one aromatic or non aromatic carbocyclic ring, such as piperonyl butoxide, sesamol, verbutin or MGK 264. For the same dose, the activity of the present formulations is greater than that of the mixture of the two active components alone or separately complexed with cyclodextrin. The process for preparing said formulation and its use for the activities herein indicated are further aspects of the present invention.

The invention relates to the use of a derivative compound of 1,3-benzodioxole of formula (I) wherein R is a linear or branched (C-C)alkyl substituent as a synergistic compound of insecticidal active ingredients insecticidal compositions comprising at least one compound of Formula (I) and at least one insecticidal active ingredient are also described. 

Use of derivative compounds of 1,3-benzodioxole in insecticidal compositions

Use of formulations comprising polyurea microcapsules obtainable by interfacial polymerization of diphenylmethylen-4,4'-diisocyanate (MDI), optionally in admixture with polymethylenepolyphenylisocyanate (PAPI), said formulations having a prolonged knockdown and killing effect longer than at least 3 months, preferably at least of 6 months, still more preferably at least of 9 months from the application, wherein the microcapsules comprise:

Use of formulations having insecticidal activity

A new high-yield, easily industrialized process for synthesizing compounds of formula (IV), in which Xand X, the same or different, are linear or branched C1-C8 alkyls, n and m are 0, 1 or 2, with the proviso that n and m are not simultaneously 0; or (OX)n and (OX)m taken together form an O-T-O group where T is chosen from &#x2014;CH&#x2014;, &#x2014;CHCH, &#x2014;CHCHCH&#x2014;, &#x2014;C(CH)&#x2014;. The process comprises treating a chloromethyl derivative (I) with an alkaline acetate to form the intermediate acetylderivative (II); the intermediate (II) is to hydrolysed to form the alcohol (III); the alcohol (III) is then oxidised in the presence of air and catalysts to obtain the desired derivative (IV). The process runs its course within a short period of time, with high yields and high selectivity; in addition, the process does not require purification and separation of the intermediates and can therefore be favourably conducted in a single batch.
