摘要:
The present invention relates to a new formulation characterised by the presence of two components, one of which (A) possesses insecticidal, acaricidal, fungicidal, snailcidal or vermicidal activity and the other (B) exhibits synergistic activity with the first by enhancing its effectiveness, and in which the average release time of component (A) is 1 to 12 hours later than the average release time of component (B). The formulation is obtained by: a) separate microencapsulation of both components (A) and (B) within a multilayer system of specific polymers in which component (A) is in a more interior portion of the capsule than component (B), being separated from component (B) by a polymer layer of suitable thickness (FIG. 1); b) microencapsulation of both components within a single layer system (FIG. 2), combined with an immediate-release emulsion/microemulsion containing an additional amount of component (B).

摘要:
Provided are compositions comprising (i) a neonicotinoid; and (ii) a compound of formula (I) or (II), preferably wherein the composition is a pesticide composition, for example an insecticide composition. Also provided is use of a compound of formula (I) or (II) as a neonicotinoid synergist and use of a compound of formula (I) or (II) in combination with a neonicotinoid. Further provided are methods for controlling pests.
摘要:
Described are new insecticide compounds that are derived from 2,2-dimethyl-3-(2-methylpropenyl)cyclopropanecarboxylic acid, also known as chrysanthemic acid, insecticidal compositions that contain the compounds, methods of synthesizing the compounds and methods of eliminating harmful insects from a substrate including bringing the substrate into contact with an effective amount of one or more such compounds.
摘要:
A new process for synthesizing 3,4-dioxo-substituted aromatic aldehydes by Oppenauer oxidation of the corresponding benzyl alcohols is described. The process, which specifically uses formaldehyde as hydrogen acceptor, proceeds with unexpectedly high yields and conversion percentages, allowing low cost access to finished and intermediate products of high industrial interest in the field of pharmaceutical products and fragrances.
摘要:
A new high-yield, easily industrialized process for synthesizing compounds of formula (IV), in which X1 and X2, 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 (OX1)n and (OX2)m taken together form an O-T-O group where T is chosen from —CH2—, —CH2CH2, —CH2CH2CH2—, —C(CH3)2—. 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.

摘要:
A composition comprising an alkynyl phenoxy compound of Formula (I) as a synergist and a pesticidal active ingredient is described, wherein R1 and R2, similar or different, are (C1-C4)alkyl or R1O— and R2O— together represent a group —O—CH2—O—, —O—CH(CH3)—O, —O—CH2—CH2—O—, —O—CH2—CH2—, R3 is (C1-C6)alkyl, (C3-C6)alkenyl or —B—(CH2—CH2—O)z-R6 where B is —CH2—O— or —O—, z is 0, 1 or 2 and R6 is (C1-C4)alkyl; R4 is hydrogen or methyl; R5 is hydrogen or methyl; x is an integer from 1 to 2; y is 0, 1 or 2; with the proviso that when R3 is —B—(CH2CH2—O)z-R6, y is 1 and 5-(propargyloxy)-benzo[1,3]dioxole is excluded.
摘要:
The present invention provides a formulation characterised 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.
