ABSTRACT:
The present invention relates to a pesticide which comprises a pesticidally active combination of active ingredients, a method of controlling pests using this composition, a process for the preparation of the composition, its use, plant propagation material treated with the composition, and to the use of a compound of the formulae (A) and (B) below for the preparation of the composition.
Certain mixtures of active ingredients are proposed in the literature for the purposes of pest control. However, the biological properties of these known mixtures are not fully satisfactory in the field of pest control, which is why there is a need to provide other mixtures, especially those which have synergistic properties, for example synergistic pesticidal properties, in particular for controlling insects and representatives of the order Acarina. This object is achieved in accordance with the invention by providing the present composition.
The invention relates to a pesticidal composition which comprises, in variable quantities, the pesticidally active compound of the formula
in free form or in the form of an agrochemically acceptable salt,
and the pesticidally active compound of the formula
in free form or in the form of an agrochemically acceptable salt, and at least one auxiliary.
The compound (E)-4,5-dihydro-6-methyl-4-(3-pyridylmethyleneamino)-1,2,4-triazin-3(2H)one(pymetrozine) of the formula (A), is known, for example, from The Pesticide Manual, 10
th
Ed. (1994). The British Crop Protection Council, London, page 868.
The compound 4-phenoxyphenyl (RS)-2-(2-pyridyloxy)propyl ether(pyriproxyfen) is known from The Pesticide Manual, 10
th
Ed. (1994). The British Crop Protection Council, London, page 887.
The agrochemically acceptable salts of the compounds of the formulae (A) and (B) are, for example, acid addition salts of inorganic and organic acids, in particular of hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, perchloric acid, phosphoric acid, formic acid, acetic acid, trifluoroacetic acid, oxalic acid, malonic acid, toluenesulfonic acid or benzoic acid.
Preferred within the scope of the present invention are compositions which comprise, as active ingredients, the compounds of the formulae (A) and (B) in free form.
The active ingredient combination according to the invention comprises the active ingredient of the formula (A) and the active ingredient of the formula (B) preferably in a mixing ratio (weight ratio, molar weight ratio or ratio of the LD
50
values of the pests to be controlled in each case) of from 1:200 to 200:1, in particular 1:50 to 50:1, more particularly in a ratio of between 1:20 and 20:1, especially between 10:1 and 1:10, also preferably between 50:1 and 3:1, very especially between 40:1 and 10:1, also preferably between 2:1 and 1:2, on the other hand in a ratio of 150:1, 40:1 or 30:1, or 20:1, or 20:3, or 15:1, or 10:1, or 5:1, or 5:2, or 5:3, or 5:4, or 4:1, or 4:3, or 3:1, or 3:2, or 2:1, or 1:20, or 1:10, or 1:5, or 2:5, or 3:5, or 4:5, or 1:4, or 3:4, or 1:3, or 2:3, or 1:2, or 1:1.
The invention also relates to a combination, in variable quantities, of the pesticidally active compound of the formula (A), in free form or in the form of an agrochemically acceptable salt, with the pesticidally active compound of the formula (B), in free form or in the form of an agrochemically acceptable salt.
Surprisingly, it has now been found that the combination of the active ingredient of the formula (A) with the active ingredient of the formula (B) not only causes the additive supplementation of the biocidal and the physical properties to be expected in principle, but that it generates a synergistic effect which, inter alia, widens the range of the pesticidal activity of the two compounds.`
Surprisingly, it has now been found that, in particular, for example the pesticidal activity of the compositions according to the invention is not only additive in comparison with the pesticidal activities of the individual components (A) and (B), as can essentially be expected, but that a synergistic effect is present. The term “synergistic” in the present context is however by no means restricted to the pesticidal activity, but the term also relates to other advantageous properties of the compositions according to the invention in comparison with the individual components (A) and (B). Examples of such advantageous properties which may be mentioned are: a widening of the pesticidal spectrum of action to include other pests, for example resistant strains, a reduced rate of application of the compounds of the formulae (A) and (B), sufficient control of the pests with the aid of the compositions according to the invention even at a rate of application at which the individual compounds (A) and (B) are entirely ineffective; advantageous behaviour upon formulation and/or application, for example upon grinding, screening, emulsifying, dissolving or dispersing; improved storage stability; better light stability; more advantageous degradation behaviour; improved toxicological or ecotoxicological behaviour; or other advantages known to those skilled in the art.
The compositions according to the invention are preventively and/or curatively valuable in the field of pest control, even at low rates of concentration, while being well tolerated by warm-blooded species, fish and plants, and have a very advantageous biocidal spectrum. The compositions according to the invention are active against all or some developmental stages of normally sensitive, but also resistant, animal pests such as insects and representatives of the order Acarina. The insecticidal and/or acaricidal activity of the compositions according to the invention can manifest itself directly, i.e. in destruction of the pests, which takes place immediately or only after some time has elapsed, for example during ecdysis, or indirectly, e.g. in a reduced oviposition and/or hatching rate, the good activity corresponding to a destruction rate (mortality) of at least 40 to 50%.
