  • the active ingredient mixture of the compounds of formula I with the insecticides described above comprises a compound of formula I and an insecticide as described above preferably in a mixing ratio of from 100:1 to 1 :6000, especially from 50:1 to 1 :50, more especially in a ratio of from 20:1 to 1 :20, even more especially from 10:1 to 1 :10, very especially from 5:1 and 1 :5, special preference being given to a ratio of from 2:1 to 1 :2, and a ratio of from 4:1 to 2:1 being likewise preferred, above all in a ratio of 1 :1 , or 5:1 , or 5:2, or 5:3, or 5:4, or 4:1 , or 4:2, or 4:3, or 3:1 , or 3:2, or 2:1 , or 1 :5, or 2:5, or 3:5, or 4:5, or 1 :4, or 2:4, or 3:4, or 1 :3, or 2:3, or 1 :2, or 1 :600, or 1 :300, or 1 :150, or 1 :35,
  • the mixtures comprising a compound of formula I and an insecticide as described above can be applied, for example, in a single "ready-mix” form, in a combined spray mixture composed from separate formulations of the single active ingredient components, such as a "tank-mix", and in a combined use of the single active ingredients when applied in a sequential manner, i.e. one after the other with a reasonably short period, such as a few hours or days.
  • the order of applying the compounds of formula I and the neonicotinoid insecticides as described above is not essential for working the present invention.
  • compositions can also comprise further solid or liquid auxiliaries, such as stabilizers, for example unepoxidized or epoxidized vegetable oils (for example epoxidized coconut oil, rapeseed oil or soya oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, fertilizers or other active ingredients for achieving specific effects, for example bactericides, fungicides, nematocides, plant activators, molluscicides or herbicides.

  • Typical rates of concentration are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient.
  • the rate of application per hectare is generally 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g/ha, preferably 10 to 600 g/ha.
  • a preferred method of application in the field of crop protection is application to the foliage of the plants (foliar application), it being possible to select frequency and rate of application to match the danger of infestation with the pest in question.
  • the active ingredient can reach the plants via the root system (systemic action), by drenching the locus of the plants with a liquid composition or by incorporating the active ingredient in solid form into the locus of the plants, for example into the soil, for example in the form of granules (soil application).
  • compositions according to the invention are also suitable for the use in plant propagation material, for example seeds.
  • the propagation material can be treated with the compositions prior to planting, for example seed can be treated prior to sowing.
  • the compositions can be applied to seed kernels (coating), either by soaking the kernels in a liquid composition or by applying a layer of a solid composition. It is also possible to apply the compositions when the propagation material is planted to the site of application, for example into the seed furrow during drilling.
