Process for the preparation of benzyl-ethers

Pesticide compounds, compositions and process for the preparation thereof

Pesticide formulations and process for the manufacture thereof

The invention relates to novel 1,2-dihydro-1,2,4,5-tetrazine derivatives of the formula (IV) ##STR1## wherein means fluorine, chlorine or bromine; and

Acaricidally active tetrazine derivatives

The invention relates to novel tetrazine derivatives of the formula (I), ##STR1## wherein X is fluorine, chlorine or bromine; and

The invention relates to novel combined compositions for combatting plant, animal and sanitarian as well as forestry, horticultural and warehouse pests. These compositions contain a pyrethroid-type insecticide as an insecticidally active ingredient and at least one fungicide inhibiting the ergosterol biosynthesis as activity-strengthening agent as well as optionally piperonylbutoxide and other additives. The advantages of the compositions according to the invention consist therein that the activity-strengthening substances used are fungicidal agents widely used and have an advantageous toxicology. The activity-strengthening agent exerts a synergistic effect together with the pyrethroid-type insecticide. The combinations according to the invention bear an outstanding importance in the protection of stored crops.

Combined compositions

Pesticidal compositions comprising ethoxylated citric or tartaric acid

ULV plant protecting arthropodicidal formulation comprising alkyl aryl polyglycol ether as further additives in addition to the active ingredient(s) dissolved in the mixture of alphatic hydrocarbons and sunflower oil. The formulation according to the invention has an initial contact angle on the plant surface of &gt;13.degree., after 20 minutes of &gt;6.degree. and it is often 120 minutes still at least 2.degree..

Plant protecting agent

A process is disclosed for preparing a synergistic, crystalline product consisting of solely enantiomer pair 1RCisS and 1SCisR and enantiomer pair 1RTransS and 1STransR of cypermethrin in a 3:7 to 5:5 crystalline mixture, which comprises the steps of: (a) epimerizing an oily melt or a saturated solution of enantiomer pair 1RCisS and 1SCisR and enantiomer pair 1RTransS and 1STransR in a ratio other than 3:7 to 5:5, or a mixture of enantiomer pair 1RCisS and 1SCisR, enantiomer pair 1RTransS and 1STransR together with enantiomer pair 1RCisR and 1SCisS and enantiomer pair 1RTransR and 1STransS, said saturated solution including a protic or apolar, aprotic inert organic solvent by treating said oily melt or saturated solution with an organic or inorganic base at a temperature of -15.degree. C. to 30.degree. C. to precipitate crystals consisting solely of the 1RCisS and 1SCisR and the 1RTransS and 1RTransR enantiomer pairs in a 3:7 to 5:5 weight ratio; (b) isolating the precipitated crystals consisting solely of the enantiomer pairs 1RCisS and 1SCisR and 1RTransS and 1STransR at -10.degree. to 30.degree. C., optionally after inoculating the reaction mixture with a seeding crystal consisting of a mixture of the enantiomer pairs 1RCisS and 1SCisR and 1RTransS and 1STransR at a weight ratio of 3:7 to 5:5 before crystallization; and (c) repeating any of the above steps, if necessary.

Insecticidal composition comprising more than one active ingredient

A graft lyotropic liquid crystalline composition having a viscosity less than 10 Pa.s comprising a low amount of surfactant(s), optionally co-surfactant(s), and/or solvents, optionally a polymer in relative stretched state and which is partly or totally penetrable by the medium and a solid material having a surface free energy of 18 to 240 mN/m.

Multiphase systems

Plant-protective composition of increased stability containing nonionic

The present invention relates to a multi-component pesticidal composition against anthropoda containing as active ingredient pyrethroides and phosphate esters and optionally piperonyl butoxide and excipients comprising as pyrethroid component 0.1 to 40 percent by weight of cypermethrin related to the total weight comprising out of the 8 possible isomers 40 to 100 percent by weight of 1RcisS and/or 1RtransS stereoisomer and as a second component at least one phosphoric acid, thiophosphoric acid or dithiophosphate being toxic on arthropoda at a ratio of 1:1-99 related to the amount of cypermethrin.

Pesticide composition

According to the present invention there is provided a synergistic insecticidal composition containing more than one active ingredients and being harmless to environment characterized by comprising in an amount of from 0.001 to 99% by weight a synthetic pyrethroid of the Formula /I/ ##STR1## namely substantially only the 1RtransS and 1StransR entantiomer-pair /Ib/ out from the possible eight isomers--optionally in admixture with an amount of up to 100% by weight of one or more activator/s/ and auxiliary agent/s/, particularly antioxidants, stabilizing agents, wetting agents, emulsifying agents, dispersing agents, antifoam agents, diluents and/or fillers. The enantiomer-pair Ib consisting of the 1RtransS and 1StransR isomers is new and the invention also relates to the said new enantiomer-pair and a process for the preparation thereof. The advantage of the insecticidal composition of the present invention is that it is less toxical towards warm-blooded animals and useful parasites and is therefore much less harmful to the environment.

A veterinary composition is disclosed which is suitable against endoparasites and which contains as active ingredients:

Veterinary compositions against endoparasites containing cypermethrin
