Pesticidal sulfur compounds

Pyrazole, pyrrole and imidazole derivatives having formula (I) or (II): ##STR1## wherein .dbd.X is .dbd.NR.sup.3, .dbd.O or an electron pair and Q comprises certain pyrazole, pyrrole and imidazole structures which, together with the remaining substituents, are defined in the description, are useful for controlling arthropod, nematodes, helminth or protozoan pests.

A pesticidal combination comprising a compound of formula (I) and a 1-arylpyrazole of formula (II). ##STR1##

Pesticidal combination

A nursery box comprising a growth substrate for rice, rice seeds and an aqueous formulation for treating said rice seeds to protect rice plants against insects for a prolonged period of time.

Nursery boxes for rice seed

Process for treating rice plants or rice propagation material against insects with a view to obtaining sustained and effective protection of the plant after the sowing period, characterized in that there is applied to the said plants or to their propagation material an effective amount of an insecticide other than an organophosphorus insecticide having systemic properties which is capable of having a long-lasting effect, that is to say even persisting on the growing plant after germination. This process is used with a pyrazole insecticide. The invention also applies to the seeds thus treated and to the nursery boxes containing them.

Process for the agrochemical treatment of rice and seeds thus treated

The invention relates to a synergistic pesticidal composition comprising:

Synergistic compositions comprising pesticidal

Process for treating rice plants or rice propagation material against insects with a view to obtaining sustained and effective protection of the plant after the sowing period, characterised in that there is applied to the said plants or to their propagation material an effective amount of an insecticide other than an organophosphorus insecticide having systemic properties which is capable of having a long-lasting effect, that is to say even persisting on the growing plant after germination. This process is used with a pyrazole insecticide. The invention also applies to the seeds thus treated and to the nursery boxes containing them.

This invention relates to a new method of plant growth regulation whereby a 1-phenylpyrazole such as fipronil is applied to a crop or a seed.

Plant growth regulation using 3-cyano-1-phenylpyrazoles such as fipronil

Method of control of corn borers attacking or susceptible or expected to attack corn plants whereby an effective amount of a 1-aryl pyrazole insecticidally active ingredient is applied near the corn sown seed. Method of protection of corn plants against European corn borer, whereby an effective amount of a 1-aryl pyrazole insecticidally active ingredient is applied near the corn sown seed.

Protection of corn

1-(Substituted phenyl)-3-(thioimidate)pyrazoles having systemic activity, arthropodicidal (especially insecticidal) and nematocidal compositions comprising same and methods for controlling arthropods (especially insects) and nematodes.

Pesticidal 1-arylpyrazole-3-carboximidothoic acid esters

Compounds of the formula 1-(4-SF.sub.5 2-R.sup.2 6-R.sup.6 phenyl) 3-CN 4-S(O).sub.n R.sup.4 5-N(R.sup.1)(R.sup.3) pyrazole, pesticidal compositions comprising them and related methods of controlling pests are disclosed.

Pesticidal 1-arylpyrazoles
