Abstract: The invention relates to a seed dressing composition containing 20 to 90% of 3-isononyloxypropyl-ammonium methyl phosphonate as active ingredient, optionally 2 to 10% by weight of a metal ion, preferably magnesium or zinc ion as well as a solid carrier and optionally other additives, preferably a surface active agent and/or adhesion promoting agent, in amounts adding up to 100% by weight, and to a method of protecting seeds against fungus attack by the application thereto of said composition.

Abstract: The invention relates to a plant protecting composition which contains 1 to 80% by weight substituted alkoxycarbonyl dithiocarbamates or thiolcarbamates of formula (I) ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and stand for hydrogen, straight or branched chain, saturated or unsaturated alkyl, alkoxyalkyl, alkylaminoalkyl, dialkylaminoalkyl having 1 to 10 carbon atoms, cycloalkyl, phenyl or halogenphenyl,R.sup.3 stands for straight or branched chain, saturated or unsaturated alkyl, cycloalkyl, phenyl or halogenphenyl, andX stands for oxygen or sulfur,as well as 10 to 90% by weight solid and/or liquid diluent(s) and 1 to 30% by weight additive(s).The novel compounds of formua (I) may be obtained in such way that a salt of disubstituted dithiocarbamic acid or thiolcarbamic acid of formula (II) ##STR2## wherein R.sup.1, R.sup.

Abstract: The invention relates to new compounds of the general formula (I), ##STR1## wherein R.sup.1 is hydrogen or a lower alkoxy group andZ.sup.1 is hydrogen, orR.sup.1 and Z.sup.1 form together a double bond,Z.sup.2 is hydrogen andB is hydroxy, orZ.sup.2 and B form together a double bond,Z.sup.3 and Z.sup.4 each stand for hydrogen or they form together an ethylene group, orZ.sup.4 and D form together a double bond,C is oxygen atom or a lower alkoxy group,D is a valence bond if C stands for oxygen, or otherwise D forms a double bond together with Z.sup.4 or Z.sup.5,Z.sup.5 forms a double bond together with D or represents hydrogen, andR.sup.2 is a group of the general formula --COOR.sup.3, wherein R.sup.3 is lower alkyl, orZ.sup.5 and R.sup.2 form together a 1-oxo-2-oxa-tetramethylene group, with the proviso that if Z.sup.3 and Z.sup.4 form together an ethylene group, R.sup.2 may stand only for a --COOR.sup.3 group,insecticidal compositions containing them, as well as to a process for their preparation.
