DESCRIPTION:

BRIEF SUMMARY
The present invention relates to insecticidal fertilizer mixtures comprising a fertilizing component and an agonist or antagonist of nicotinergic acetylcholine receptors of insects, and to their use.
Agonists or antagonists of the nicotinergic acetylcholine receptors of insects are known, for example, from the following publications:

Nos. 5,034,524, 4,948,798, 4,918,086, 5,039,686, 5,034,404; PCT Applications Nos. WO 91/17,659, 91/4965; French Application No. 2 611 114; Brazilian Application No. 88 03 621.
Reference is hereby made expressly to the methods, processes, formulae and definitions described in these publications and to the individual preparations and compounds described therein.
It is known to employ fertilizers for ornamental houseplants in the form of small fertilizer sticks.
It is also known to employ insecticides for ornamental houseplants in the form of impregnated cardboard strips which are pressed into the nutrient substrate of the plant.
Also known for keeping ornamental houseplants is a tablet which contains dimethoate as insecticidal active substance and fertilizer as carrier material. The action of this mixture, however, is not completely satisfactory.
The present invention relates to: nicotinergic acetylcholine receptors of insects with fertilizers, adhesives and optionally auxiliaries and carrier materials in the form of small sticks, plates, tablets or granules. nicotinergic acetylcholine receptors of insects, characterized in that they are employed in the form of dimensionally stable mixtures with fertilizers, adhesives and optionally auxiliaries and carrier materials. agonists or antagonists of the nicotinergic acetylcholine receptors of insects with fertilizers, characterized in that they are mixed with adhesives and optionally with auxiliaries and carrier materials and are compressed or extruded to the desired form. fertilizers, adhesives and optionally auxiliaries and carrier materials for the long-term protection of plants against insect damage, by incorporating these mixtures into the nutrient medium of the plants.
The action of the agonists or antagonists of the nicotinergic acetylcholine receptors of insects in the mixtures according to the invention begins more rapidly and persists for longer than that of the customary fertilizer-free granules. The mixtures according to the invention can be employed simply and without problems, specifically in non-commercial horticulture.
Some agonists or antagonists of the nicotinergic acetylcholine receptors of insects are covered by the class of nitromethylenes and related compounds.
These compounds can be represented preferably by the general formula (I) ##STR1## in which R represents hydrogen or optionally substituted radicals from the group acyl, alkyl, aryl, aralkyl, heteroaryl or heteroarylalkyl; acyl, alkyl, aryl or represents a bifunctional group which is linked to the radical Z; radical --CH.dbd. to be linked to the radical Z instead of one H atom; --O--R, --S--R, ##STR2## or represents a bifunctional group which is linked to the radical A or to the radical X.
Particularly preferred compounds of the formula (I) are those in which the radicals have the following meaning: the series consisting of acyl, alkyl, aryl, aralkyl, heteroaryl, heteroarylalkyl. arylcarbonyl, alkylsulphonyl, arylsulphonyl, (alkyl-)-(aryl-)-phosphoryl, which may in turn be substituted. -alkyl, specifically methyl, ethyl, i-propyl, sec.- or t.-butyl, which may in turn be substituted. and N, O, S, in particular N as heteroatoms. Thiophenyl, furyl, thiazolyl, imidazolyl, pyridyl, benzothiazolyl may be mentioned specifical
