Abstract
Description
Pesticide compositions The present invention relates to a composition comprising a combination of insecticidal active ingredients, to the preparation of such compositions, and to a method of using such a composition to control pests in useful plant crops. Insecticidal compositions containing combinations of the insecticidal active ingredient spiropidion with another active ingredient are known, for example, from WO 2013 / 107793. However, in certain compositions for use in controlling insects in crops, the chemical instability of the active ingredient (e.g., spiropidion) can be a problem, resulting in a loss of insecticidal performance. Consequently, there remains a strong incentive to develop insecticidal compositions in which, for practical purposes, the active ingredient component retains long-term chemical stability. According to the present invention, a pesticide composition is provided comprising: (i) 25 to 35% by weight of spiropidion; (ii) 20 to 30% by weight of acetamiprid; and (iii) 2.5 to 10% by weight of a buffering agent, which, based on the total weight of the composition, comprises: (a) 2 to 7% by weight of an alkali metal sulfate and / or an alkaline earth metal sulfate, and (b) 0.1 to 5% by weight of an organic acid. The pesticide compositions of the invention, for practical purposes, have a very advantageous level of activity in the control of insect pests in useful plant crops after foliar or soil application. 1593356 of 22 while also maintaining acceptable crop safety (phytotoxicity) results. By activity, it is understood that the compositions of the invention are capable of killing or controlling pests, retarding the growth or reproduction of insects, reducing the insect population and / or reducing the damage to plants caused by insects. Furthermore, it has been surprisingly found for the present invention that the addition of an organic acid (e.g. citric acid) to certain compositions comprising spiropidion and acetamiprid significantly improves the chemical stability of the spiropidion active ingredient component and thus the storage life of compositions containing these two active ingredients. Furthermore, according to the invention, an aqueous composition is provided comprising the pesticide composition according to the invention, which optionally further comprises one or more adjuvants or carriers. Furthermore, according to the invention, a (non-therapeutic) method is provided for combating and controlling pests, comprising applying a composition according to the invention to a pest, a pest locus, or a crop of a useful plant susceptible to pest attack.

EXAMPLES: The following examples serve to illustrate the invention and, in particular, demonstrate the surprising effect of using specific amounts of the organic acid citric acid as a buffering component on the stability of spiropidion in a heat storage test, thus demonstrating a viable composition for use in commercial pest control. The compositions according to the present invention are prepared according to known formulation methods, for example, for a water-dispersible (wettable) granule. Referring to Table 1 below, Composition A is a water-dispersible granule composition not according to the invention (without citric acid present), and Composition B is a water-dispersible granule composition according to the invention (with citric acid present). Composition A and Composition B are identical except for the inclusion of citric acid and a slightly lower amount of filler present in Composition B to compensate for the inclusion of the citric acid component. 1593356 of 22 To test the robustness of the chemical stability of the active ingredients (spiropidion and acetamiprid), samples of Composition A and Composition B were suspended in 50% by weight water and stored at 54°C for 2 weeks. Table 1: Component Composition A (% by weight) Composition B (% by weight) Spiropidion 30 30 Acetamiprid 24 24 Sodium sulfate 5 5 Citric acid - 1 Dispersant 17 17 Antifoaming agent 2 2 Filler 22 21 As can be seen in Table 2 below, after suspension, Composition B according to the invention remains within a 5% degradation limit for spiropidion, which is considered acceptable, whereas Composition A not according to the invention refers to unacceptable degradation of spiropidion (greater than 20% loss). Table 2: Composition A (not according to the invention) Composition B % by weight remaining after 2 weeks at 54°C (Spiropidion) 23.9 28.7 % by weight remaining after 2 weeks at 54°C (Acetamiprid) 23.8 23.9 1593356 of 22 % degradation (Spiropidion) - 20.33 - 4.33 % degradation (Acetamiprid) - 0.83 - 0.42 It is hereby stated that, as of this date, the best method known to the applicant for putting the aforementioned invention into practice is the one that is clear from the present description of the invention. 1593356 of 22 Santiago Ferrer Reyes - 20142227887 Digitally signed by PORTALTRAM ITES - INPI Date: 2021.11.25 10:30:49 -03:00 Reason: Digitally Signed by INPI Location: Buenos Aires, Argentina 1593356
Claims
1. An insecticidal composition characterized in that it comprises: (i) 25 to 35% by weight of spiropidion; (ii) 20 to 30% by weight of acetamiprid; and (iii) 2.5 to 10% by weight of a buffering agent which, based on the total weight of the insecticidal composition, comprises: (a) 2 to 7% by weight of an alkali metal sulfate and / or an alkaline earth metal sulfate, and (b) 0.1 to 5% by weight of an organic acid. 19 Claims follow
