This invention relates to methods controlling, and protecting warm-blooded animals from infestation and infection by helminths, acarids and arthropod endo- and ectoparasites by administering or applying to the animals a substituted arylpyrrole compound.

Methods for the control and the protection of warm-blooded animals

This invention relates to methods and compositions for treating, controlling, preventing and protecting warm-blooded animals from infestation and infection by helminths, acarids and arthropod endo- and ectoparasites by administering or applying to the animals a substituted arylpyrrole compound.

Substituted arylpyrrole compounds

There are provided certain insecticidal, acaricidal and molluscicidal pyrrole carbonitrile and nitropyrrole compounds and a method for controlling insects, acarids and mollusks therewith. The invention also provides a method for protecting growing plants from insect, acarid and mollusk attack by applying to said plants or the soil or water in which they are growing, an insecticidally, acaricidally or molluscicidally effective amount of a pyrrole carbonitrile or nitropyrrole compound. The present invention further relates to methods for the preparation of said pyrrole carbonitrile and nitropyrrole compounds.

This invention is directed to certain novel insecticidal, acaricidal and nematicidal arylpyrrole agents and a method for controlling insects, acarids and nematodes therewith. The invention also is directed to a method for protecting growing plants from insect, acarid and nematode attack by applying to said plants or the soil in which they are growing, an insecticidally, acaricidally or nematicidally effective amount of a novel arylpyrrole compound. The present invention further is directed to a method for the preparation of the arylpyrrole compounds.

Arylpyrrole insecticidal acaricidal and nematicidal agents and methods

This invention provides novel .alpha.-[2,2-di(C.sub.1 -C.sub.4 alkoxy)ethylamino]-.beta.-cyanostyrene and .alpha.-[2,2-di(C.sub.1 -C.sub.4 alkoxy)ethylamino]-.beta.-nitrostyrene compounds that are useful for the preparation of pesticidal arylpyrroles. The invention also provides a method for the preparation of the above-said .beta.-cyanostyrene and .beta.-nitrostyrene compounds.

.alpha.-(2,3-Di(C.sub.1 -C.sub.4 alkoxy)ethylamino)-.beta.-cyanostyrene

The invention relates to novel substituted cyclopropanecarboxylic acid esters, and to methods of preparation thereof. The invention also relates to methods of use of the compounds for the control of insect pests of agriculturally important crops, and for the control of ectoparasites, especially acarina, of domesticated warm-blooded animals.

Cyanovinyl pyrethroids and pesticidal use thereof

The invention is a novel chloro-substituted cyclopropane carboxylic acid useful for the preparation of novel insecticidal-acaricidal pyrethroids.

Chloro-substituted benzospiro cyclopropane carboxylic acid

There are provided certain spiro-cyclopropyl amidinohydrazones, and methods of use of the compounds for the control of insects, especially Lepidopterous insects, and for the control of ants, Family Formicidae, especially fire ants.

Spiro-cyclopropyl amidinohydrazones, and use as insect and fire ant

The invention relates to novel substituted cyanovinyl cyclopropanecarboxylic acids and method of preparation thereof. The cyanovinyl cyclopropanecarboxylic acids are useful intermediates for the preparation of novel insecticidal-acaricidal pyrethroids.

Cyanovinyl cyclopropanecarboxylic acids

The invention is novel halo-substituted benzospiro cyclopropane carboxylates useful for the control of insect pests of agriculturally important crops, and useful as insecticidal and acaricidal agents for the treatment of livestock and domestic animals.

Halo-substituted benzospiro cyclopropane carboxylates as insecticides

This is a novel process for the preparation of m-phenoxybenzaldehyde, a useful and valuable intermediate for the synthesis of pyrethroid type pesticides. The process comprises halogenation of m-phenoxytoluene on the side chain, in an inert solvent and in the presence of free radical initiators or strong light to a mixture of the corresponding mono and dihalo derivatives, and conversion of the mixture to m-phenoxybenzaldehyde by a Sommelet-type reaction.
