Description

FIELD OF THE INVENTION [001] The invention relates to a method for controlling invertebrate pests of sugarcane, citrus fruits, rapeseed and potato plants, comprising the step of contacting the plant, parts thereof, its propagation material, the pests, their food supply, habitat or breeding sites with one or more compounds of formula I or tautomers, enantiomers, diastereomers, or salts thereof. [002] The compound of formula I is highly suitable for methods of controlling and/or combating invertebrate pests. [003] It was also found that mixtures of the compound of formula (I) with other active agricultural ingredients, such as insecticides or fungicides or nematicides, are particularly suitable for methods of controlling and/or combating invertebrate pests. [004] The compound of formula (I) is present in two enantiomeric forms IR-1 and IS-1 as shown below: [005] The compound of formula (I) is present in mesoionic forms. These forms can be expressed in different isoelectronic formulas, each with the formal positive and negative charges on different atoms (as shown below). The present invention extends to all representative isoelectronic structures of the compound of formula I. [006] The compounds with formula I-R-1 and I-S-1 are also present in mesoionic forms analogous to the compound with formula I as shown above. [007] The invention relates to a method in which the compound of formula (I) itself and its stereoisomers, salts, enantiomers or N-oxides, especially its enantiomers, and mixtures thereof. DESCRIPTION OF THE INVENTION [008] The term “non-racemic compound of formula (I)” refers to the compound of formula (I) in which its R and S enantiomers are not present in equal amounts. [009] The term “racemic compound of formula (I)” refers to the compound of formula (I) in which its R and S enantiomers are present in equal amounts. [010] The term “enantiomeric excess” indicates the excess of one enantiomer in a mixture of enantiomers and is calculated according to the following formula: ee = [|m1 — m2| / (m1 + m2)] x 100% - ee: enantiomeric excess - m1: fraction of enantiomer 1 - m2: fraction of enantiomer 2. [011] As used in this document and unless otherwise indicated, the term “enantiomer” means each individual optically active form of a compound of the invention. [012] The term “enantiomeric excess”, as used herein, refers to a mixture of enantiomers, wherein the enantiomer in relation to which the term “enantiomeric excess” is used is present in enantiomeric excess compared to another enantiomer, preferably in an amount of at least 60%, preferably at least 80%, more preferably at least 95%, most preferably at least 98% of the mixture of enantiomers. For example, the term “compound of formula I with enantiomeric excess of compound I-R-1” refers to the compound of formula I in which compound I-R-1 is present in an amount of enantiomeric excess compared to compound I-S-1, preferably in an amount of at least 60%, preferably at least 80%, more preferably at least 95%, most preferably at least 98%. [013] Potatoes are a tuberous crop grown from the perennial plant Solanum tuberosum. Potato tubers are specialized stems of the potato plant that form just below the soil surface. It is grown in over 125 countries and consumed almost daily by over one billion people. Hundreds of millions of people in developing countries depend on potatoes for their livelihood. The potato is the fourth most consumed food crop in the world, after rice, wheat, and corn. However, the potato crop is subject to attack by invertebrate pests such as thrips, leafhoppers, aphids, moths, etc. Due to the different context, the yield and quality of potatoes can be affected by different pests, causing economic losses. [014] Many species of citrus fruits are cultivated throughout the world. Of these species, sweet oranges (C. sinensis) and mandarins (C. reticulata) are extensively cultivated worldwide and, to a more limited extent, grapefruits (C. paradise), lemons (C. limon) and limes (C. aurantifolia) and the hybrids tangelos (mandarin orange X grapefruit) and tangors (mandarin orange X sweet orange) (Rajput and Haribabu, 1993). Like most fruits, citrus fruits are a low-calorie food, a good source of carbohydrates and fiber, are low in sodium and fat, and are an excellent source of vitamin C. The phytochemicals in citrus fruits have potential beneficial properties such as antioxidant, anticancer, and cholesterol-lowering abilities (Tian et al., 2001). The fruit harvest is widely produced and marketed as fresh fruit. However, citrus fruit plants are prone to attack by arthropod pests, such as mines, aphids, psyllids, flies, weevils, etc., which causes damage to crops resulting in large economic losses. [015] Rapeseed, Brassica napus, is an annual winter or spring crop of the Brassica family. It is also known as rapeseed and oilseed rapeseed. Canola is a genetic variation of rapeseed developed through traditional breeding by Canadian breeders. Ra
