Description

Composition and method for controlling plant invasion by insects The present invention relates to a composition and a method for controlling or preventing the infestation of plants such as maize or cotton by insects, in particular Spodoptera littoralis and Diabrotica balteata . Specific active ingredients and combinations of active ingredients for controlling pest attacks are described in the literature. In particular, there is a continuing need to provide insecticidal combinations that offer improved, for example biological properties, or synergistic properties, for the control of insect, acarina, and nematode pests. Benefits may also include an increased safety profile, improved physicochemical properties, or increased biodegradability. A specific combination of active ingredients has been found to provide unexpected control or prevention of plant infestation when applied to plants, their sites, or their breeding materials. More specifically, the specific combination has now been found to be highly effective in controlling or preventing plant infestation by various insect pests of the Lepidoptera and Coleoptera orders, such as Spodoptera genus, particularly Spodoptera ritoralis , and Diabrotica genus, particularly Diabrotica valteata . Accordingly, in one embodiment, the present invention has a compound of formula A-1 as component (A): (A-1; cyclobutrifuram) and, as component (B), a compound of formula B-1: (B-1; Ciatraniliprol) A composition comprising, Here, the weight ratio of (A) to (B) is 500:1 to 1:500, 100:1 to 1:100, 125:1 to 1:125, 50:1 to 1:50, 25:1 to 1:25, or 20:1 to 1:20, or preferably 10:1 to 1:10, 8:1 to 1:8, 6:1 to 1:6, or 5:1 to 1:5 on a weight basis; More preferably, the ratio is 4:1 to 1:4, 10:3 to 3:10, 3:1 to 1:3, 2.5:1 to 1:2.5, 2:1 to 1:2, 5:3 to 3:5, 8:5 to 5:8, 1.5:1 to 1:1.5, 4:3 to 3:4, 5:4 to 4:5, or about 1:1. In another aspect, the present invention provides a method for controlling or preventing infestation of plants by insects of the order Lepidoptera and Coleoptera, wherein the method comprises, on a plant, a place thereof, or a breeding material thereof, a compound of formula A-1 as component (A) in any desired order or simultaneously: (A-1) and, as component (B), a compound of formula B-1: (B-1) It includes the step of applying a combination or composition containing References to cyclobutrifluram, a compound of formula A-1, and ciatraniliprol, a compound of formula B-1, also include isomers, tautomers, N-oxides, esters, prodrugs, isotopes, and protected forms, including their agrochemically acceptable ionic forms, salts, solvates, geometric and stereochemical isomers. Preferably, references to the compound of formula A-1 and the compound of formula B-1 also include their salt or tautomer or isomer or N-oxide or solvate; more preferably, their salt or tautomer or N-oxide or solvate, even more preferably, their salt or tautomer or solvate. Cyclobutrifluram comprises 80 to 100% of N-[(1S,2S)-2-(2,4-dichlorophenyl)cyclobutyl]-2-(trifluoromethyl)pyridine-3-carboxamide (hereinafter "(1S,2S) enantiomer") as exemplified below as a compound of formula A-1a, and 20 to 0% of the corresponding (1R,2R)-enantiomer (hereinafter "(1R,2R) enantiomer") as exemplified below as a compound of formula A-1b. These enantiomers occur because the phenyl ring on the left and the pyridyl-C(=O)-NH group on the right are cis to each other in the cyclobutyl ring. According to the present application, the compound of formula A-1 may comprise at least 85%, preferably at least 90%, more preferably at least 95% of N-[(1S,2S)-2-(2,4-dichlorophenyl)cyclobutyl]-2-(trifluoromethyl)pyridine-3-carboxamide.
