Description

[Technical field]

[0001] The present invention relates to suspension concentrate compositions containing a pesticidal active ingredient, their preparation, and methods of using such compositions to control pests in crops of useful plants. [Background technology]

[0002] A pesticide adjuvant may be defined as a substance present in a pesticide spray formulation that is either incorporated into the active ingredient concentrate (i.e., so-called "built-in" adjuvants) (diluted in the spray tank prior to spraying) or that is added to the spray tank prior to spraying and is not a component of the active ingredient concentrate (i.e., so-called "tank-mix" adjuvants) and that improves the performance of the pesticide active ingredient, for example, by spreading the active ingredient over the leaf surface or promoting leaf penetration. The use of built-in adjuvants in an agrochemical formulation may simplify the spray process by eliminating the step of separate addition of the adjuvant to the spray tank, which may be preferred in certain circumstances.

[0003] WO 2004 / 007448 and WO 2010 / 066780 disclose that certain spiroheterocyclic pyrrolidinedione derivatives have pesticidal activity, in particular insecticidal, acaricidal, molluscicidal and nematocidal activity. Such derivatives act systemically and can penetrate into plant leaves and travel through the plant's vascular system upon foliar application. For this reason, these derivatives are particularly effective against insect sucking pests, such as aphids, thrips and whiteflies. However, when applying compositions containing such derivatives to plants, it is important to strike a balance between achieving acceptable pesticidal efficacy and limiting the phytotoxic consequences that may result from excessive penetration of active ingredients into the plant. Summary of the Invention [Problem to be solved by the invention]

[0004] Thus, there remains a motivation in the development of agrochemical formulations, especially those containing incorporated adjuvants, for new compositions that meet these dual requirements of obtaining optimized pesticidal (insecticidal) efficacy while limiting phytotoxicity and therefore significant damage to the plant (crop safety). [Means for solving the problem]

[0005] According to the present invention, (i) as an active ingredient a compound of formula (I): [ka] (In the formula, A is hydrogen or methyl; U is independently chloro or methyl; n is 1 or 2; G is hydrogen or -C(=O)OCH2CH3; X is N or C(H); or an agrochemically acceptable salt thereof; (ii)(a) oxirane / methyloxirane block copolymers (polyoxyethylene / polyoxypropylene block copolymers); and (b) Alcohol alkoxylate and a pesticidal composition comprising: wherein the weight ratio of component (a) to component (b) is 1:3 to 3:1; The weight ratio of components (i) and (ii) is 1:1 to 1:4.

[0006] Surprisingly, it has been found that the compositions of the present invention have a very advantageous level of activity in controlling pests in useful plant crops after foliar or soil application, while also maintaining, for practical purposes, acceptable crop safety (phytotoxicity) results.By activity, it is meant that the compositions of the present invention can kill or control insects, retard insect growth or reproduction, reduce insect populations, and / or reduce the damage caused by insects to plants. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] In a second aspect of the invention, there is provided a method for combating and controlling pests which comprises applying a composition according to the invention to the pest, to a habitat of the pest, or to a crop of useful plants susceptible to attack by the pest.

[0008] In a third aspect of the present invention there is provided a method for controlling pests, the method comprising applying a composition according to the present invention to the soil of a crop of useful plants, wherein application is by dripping, dipping or injecting into the soil.

[0009] Preferably, the composition according to the invention is a suspension concentrate formulation. A suspension concentrate (SC) formulation is a stable suspension of a solid pesticidal active ingredient in a liquid, which is usually intended for dilution before use. Ideally, the suspension should be stable (i.e., not settle). Suspension concentrate formulations are generally diluted with water before conventional spraying through a nozzle, and in addition to the active ingredient, may also contain other auxiliaries, such as surfactants, emulsifiers, dispersants, wetting agents, antifreezes, defoamers, biocides, solvents, stabilizers, antimicrobial agents, pigments, buffers, surface-active substances, etc. Such substances are known to those skilled in the art of agrochemical formulations. Suspension concentrate formulations may be prepared by ball milling or bead milling a solid active ingredient compound in a suitable medium, optionally with one or more dispersing agents, to produce a suspension of fine particles of the compound. One or more wetting agents may be included in the composition, and suspending (anti-settling) agents may be included to reduce the rate at which the particles settle. Alternatively, the active ingredient may be dry milled and added to water containing the agents listed above to produce the desired final product.

Compound 1 may be prepared by the procedures described in WO 2010 / 066780, WO 2018 / 114649 and WO 2018 / 114648.

[0030] The commercially available adjuvants used in the example compositions are Pluronic® PE6400 (BASF AG) and Pluronic® PE10500 (BASF Corporation, USA), which are oxirane / methyloxirane block copolymers with molecular weights (g / mol) ranging from 2500 to 7000. Plurafac® LF404 is a methyl oxirane block copolymer that is primarily composed of ethoxylated and propoxylated C 13 ~C 15 It is a low-foaming nonionic surfactant made from alcohol (liquid at 23°C).

[0031] Insecticidal activity and crop safety were tested on 4-week-old Chinese cabbage (Brassica rapa) plants infested with green peach aphids (Myzus persicae). Plants were treated by horizontal spraying at the rates indicated and incubated at 22°C with a 14-hour light regime and approximately 60% relative humidity. Plants used for efficacy (activity) evaluation were infested with populations of various ages of green peach aphids (Myzus persicae) 2 hours and 6 days after application. Plants used for crop safety evaluation remained uninfested and were kept separately but under identical environmental conditions. One and two weeks after application, efficacy (i.e. aphid control against test criteria) and crop safety (i.e. phytotoxicity against untreated) were assessed for each individual treatment. Each treatment was performed in triplicate, i.e. on three individual plants.

[0032] Compositions A-1 to I-1 were assessed for insecticidal activity against a spiropydione formulation applied at 50 g / ha active ingredient with rapeseed oil methyl ester (RME) EW40 as adjuvant in a 1:2 weight ratio achieving a score of 100 (acceptable activity) as standard.

[0033] Compositions A-2 to I-2, having the same active ingredient to adjuvant weight ratio as formulations A-1 to I-1, were assessed for crop safety against formulations applied at 100 g / ha active ingredient with rapeseed oil methyl ester (RME) EW40 standard as adjuvant achieving a score of 100 (acceptable crop safety) as standard.

[0034] The relative performance of Formulations A-1 to I-1 (activity) and A-2 to I-2 (crop safety) was scored against their respective standards based on the following:

[0035] A (- / -) rating was considered not acceptable for activity at a particular rate of active ingredient application; a (-), (+) or (+ / +) rating was considered acceptable. - / - Less than 90. - 90~99. + 101~110. + / + Over 110.

[0036] A (- / -) rating was not considered acceptable for crop safety at a particular rate of active ingredient application, whereas a (-), (+) or (+ / +) rating was considered acceptable. Less than + / - 90. + 90~99. - 101~110. - / - Over 110.

[0037] [Table 1]

[0038] As can be seen from Table 1, only compositions B, C, F and I having a weight ratio between compound 1 according to the invention and adjuvants (a) and (b) were not scored as unacceptable (- / -) for insecticidal activity or unacceptable (- / -) for crop safety relative to the standard formulation.
