ABSTRACT:

The present invention relates to a novel pesticidal composition for controlling harmful insects and representatives of the order Acarina, and to a method of controlling these pests with the composition in question.
When controlling plant pests, in particular insects and spider mites in agricultural crops, especially in monocultures, it is an aim to keep the contact between not only the crop plants, but also their environment and the soil in which they grow, and the pesticidally active ingredients to a minimum. However, it is nevertheless intended to expose the pests themselves, which are mainly found on the plants, to the active ingredient as intensely as possible, for example by contact action or by action as a stomach poison. It is furthermore attempted to ensure that the adverse effects of the pesticidally active ingredients on beneficial animals and warm-blooded species are not substantial. To achieve these aims, pesticides and control methods have been proposed whose principal is that the behaviour of the target pests can be controlled or altered, with the aid of signal substances, for example using pheromones, in such a way that the pests are led to a source of a pesticidal active ingredient, which source is provided in separate areas within the cultivated area to be protected (so-called attract-and-kill methods, EP-A-376 888). Such methods have been successful in particular for controlling adult pests. However, the control of larvae of these pests, using these methods, is very poor indeed since these larvae are generally of low mobility and will therefore hardly find the source of the signal substances and thus the pesticide. Naturally, in contrast, eggs of those pests cannot be controlled at all using such methods. Thus, if one intends to achieve that, on the one hand, not only the crop plants to be protected, but also the soil in which they grow, come into as little contact as possible with pesticidally active ingredients but, on the other hand, the pests found on the plants are exposed to the active ingredients as intensely as possible while simultaneously leaving the beneficial animals unharmed, the method of choice will be the attract-and-kill methods described in the literature. However, as discussed, one will have to accept that it is hardly possible, using this method, to control the larvae present in the crop, and not at all possible to control the eggs which have been deposited in the period during which the crop has been treated with the composition in question. Thus, this means that the crop may be reinfested with the pest a short time after the treatment. There is therefore still a demand for a method of controlling pests which, in the manner described above, not only leaves plants and environment largely unharmed, but which is also capable of destroying not only the adults, but in particular the eggs and larvae, very especially preferably the eggs, of the pests so as to prevent the pest from spreading further.
The abovementioned shortcomings are overcome by control method and composition according to the invention. The invention relates to a flowable composition for controlling harmful insects and representatives of the order Acarina, comprising at least one pesticidally active compound, one or more signal substances selected from the group consisting of pheromones, kairomones and attractants, a UV absorber or a UV absorber mixture and, if appropriate, one or more additives selected from the group consisting of viscosity-regulating thickeners, fillers, solvents and other formulation auxiliaries,
which comprises 40 to 98% by weight of the UV absorber or of the UV absorber mixture,
0.01 to 30% by weight of one or more signal substance(s), and
0.1 to 20% by weight of one or more pesticidally active compound(s) selected from the group consisting of the compounds of the formula
