The invention also relates to seed comprising compounds of formula 1.

The invention further relates to the use of compounds of formula I for the protection of seeds from soil pests.

One typical problem arising in the field of protection of seeds lies in the need to reduce the dosage rates of the active ingredient in order to reduce or avoid unfavorable environmental or toxicological effects whilst still allowing effective soil pest control.

Another problem encountered concerns the need to have available seed protection agents which are effective against a broad spectrum of soil pests.

There also exists the need for seed protection agents that combine know-down activity with prolonged control, that is, fast action with long lasting action.

Another difficulty in relation to the use of seed protection pesticides is that the repeated and exclusive application of an individual pesticidal compound leads in many cases to a rapid selection of soil pests which have developed natural or adapted resistance against the active compound in question. Therefore there is a need for seed protection agents that help prevent or overcome resistance.

It was therefore an object of the present invention to provide compounds which solve the problems of reducing the dosage rate and/or enhancing the spectrum of activity and/or combining know-down activity with prolonged control and/or to resistance management.

We have found that these objects are in part or in whole achieved by the compounds of formula I and compositions comprising them.

The insecticidal and acaricidal activity in plant protection in the agricultural field of some of the compounds of formula I has been described in EP-A 604 798, and also in J. A Furch et al.,"Amidrazones : A New Class of Coleopteran Insecticides", ACS Sym- <BR> <BR> posium Series 686, Am. Chem. Soc. , 1998, Chapter 18, p. 178 ff, and also in D. G.

Kuhn et al.,"Cycloalkyl-substituted Amidrazones: A Novel Class of Insect Control Agents", ACS Symposium Series 686, Am. Chem. Soc., 1998, Chapter 19, p. 185 ff.

Activity of compounds in plant protection against agricultural pests does not suggest their suitability for the protection of seeds which requires, for example, activity against soil pests, compatibility with the soil conditions (e. g. concerning binding of the com- pound to the soil), negligible phytotoxicity when applied to the seed, and appropriate movement to achieve necessary bioavailability (in soil or plant).

Application to the seeds is carried out before sowing, either directly on the seeds or after having pregerminated the latter.

For use according to the present invention, the compounds I can be converted into the customary formulations, e. g. solutions, emulsions, suspensions, dusts, powders, pastes and granules. The use form depends on the particular purpose; it is intended to ensure in each case a fine and uniform distribution of the compound on the seed according to the invention.

The formulations are prepared in a known manner, e. g. by extending the active ingredient with solvents and/or carriers, if desired using emulsifiers and dispersants.

Solvents/auxiliaries, which are suitable, are essentially: - water, aromatic solvents (for example Solvesso products, xylene), paraffins (for example mineral fractions), alcohols (for example methanol, butanol, pentanol, benzyl alcohol), ketones (for example cyclohexanone, gamma-butyrolactone), pyrrolidones (NMP, NOP), acetates (glycol diacetate), glycols, fatty acid dimethylamides, fatty acids and fatty acid esters.

of solid carriers are mineral earths such as silica gels, silicates, talc, kaolin, attaclay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as, for example, ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders and other solid carriers.

Stickers/adhesion agents can be added to improve the adhesion of the active materi- als on the seeds after treatment. Suitable adhesives are block copolymers EO/PO sur- factants but also polyvinylalcoholsl, polyvinylpyrrolidones, polyacrylates, polymethacry- lates, polybutenes, polyisobutylenes, polystyrene, polyethyleneamines, polyethyl- eneamides, polyethyleneimines (Lupasol0, Polymin0), polyethers, polyurethans and copolymers derived from these polymers.

In general, the formulations comprise from 0.01 to 95% by weight, preferably from 0.1 to 90% by weight, of the active ingredient. The active ingredients are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).

The following are examples of formulations: 1. Products for direct application or for application after dilution with water A) Soluble concentrates (LS) 10 parts by weight of the active compounds are dissolved in water or in a water-soluble solvent. As an alternative, wetters or other auxiliaries are added. The active compound dissolves upon dilution with water.

B) Dispersible concentrates (DC) 20 parts by weight of the active compounds are dissolved in cyclohexanone with addition of a dispersant, for example polyvinylpyrrolidone. Dilution with water gives a dispersion.

C) Emulsifiable concentrates (EC) 15 parts by weight of the active compounds are dissolved in xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5% strength).

Dilution with water gives an emulsion.

D) Emulsions (ES) 40 parts by weight of the active compounds are dissolved in xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5% strength).

This mixture is introduced into water by means of an emulsifier (Ultraturax) and made into a homogeneous emulsion. Dilution with water gives an emulsion.

E) Suspensions (FS) In an agitated ball mill, 20 parts by weight of the active compounds are comminuted with addition of dispersant, wetters and water or an organic solvent to give a fine active compound suspension. Dilution with water gives a stable suspension of the active compound.

F) Water-dispersible granules and water-soluble granules (WG, SG) 50 parts by weight of the active compounds are ground finely with addition of dispersants and wetters and made into water-dispersible or water-soluble granules by means of technical appliances (for example extrusion, spray tower, fluidized bed).

Dilution with water gives a stable dispersion or solution of the active compound.

G) Water-dispersible powders and water-soluble powders (SS, WS) 75 parts by weight of the active compounds are ground in a rotor-stator mill with addition of dispersant, wetters and silica gel. Dilution with water gives a stable dispersion or solution with the active compound.

2. Products to be applied undiluted H) Dustable powders (DS) 5 parts by weight of the active compounds are ground finely and mixed intimately with 95% of finely divided kaolin. This gives a dustable product.

I) Granules (GR, FG, GG, MG) 0.5 part by weight of the active compounds is ground finely and associated with 95. 5% carriers. Current methods are extrusion, spray-drying or the fluidized bed. This gives granules to be applied undiluted.

The active ingredients can be used as such, in the form of their formulations or the use forms prepared therefrom, eg. in the form of directly sprayable solutions, powders, gels, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, microcapsules (CS), pellets or tablets, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; it is intended to ensure in each case the finest possible distribution of the active ingredients according to the invention.

Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier.

Alternatively, it is possible to prepare concentrates composed of active substance,

wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.

The active ingredient concentrations in the ready-to-use products can be varied within relatively wide ranges. In general, they are from 0.01 to 80%, preferably from 0.1 to 50%.

Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active ingredients, if appropriate just immediately prior to use. These agents usually are admixed with the agents according to the invention in a weight ratio of 1: 100 to 100: 1.

Preferred are FS formulations.

Preferred FS formulations of compounds of formula I for seed treatment comprise from 0.5 to 80% of the active ingredient, from 0,05 to 5 % of a wetter, from 0.5 to 15 % of a dispersing agent, from 0,1 to 5 % of a thickener, from 5 to 20 % of an anti-freeze agent, from 0,1 to 2 % of an anti-foam agent, from 1 to 20 % of a pigment and/or a dye, from 0 to 15 % of a sticker/adhesion agent, from 0 to 75 % of a filler/vehicle, and from 0,01 to 1 % of a preservative.

In the control of pests, the application of the compound of formula I or of the composi- tion comprising it is carried out by spraying or dusting the seeds or the soil (and thereby the seeds) after sowing.

A further subject of the invention is a method of treating the seed in the seed drill with a granular formulation containing the active ingredient or a composition comprising it, with optionally one or more solid or liquid, agriculturally acceptable carriers and/or op- tionally with one or more agriculturally acceptable surfactants. This method is advanta- geously employed in seedbeds of cereal, maize, cotton and sunflower. For cereals and maize, the rates for compounds of formula I are between 50 and 500 g/ha.

The invention also relates to the propagation product of plants, and especially the treated seed comprising, that is, coated with and/or containing, a compound of formula I or a composition comprising it. The term"coated with and/or containing"generally signifies that the active ingredient is for the most part on the surface of the propagation product at the time of application, although a greater or lesser part of the ingredient

may penetrate into the propagation product, depending on the method of application.

When the said propagation product is (re) planted, it may absorb the active ingredient.

In general,"pesticidally effective amount"means the amount of active ingredient needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various compounds/compositions used in the invention. A pesticidally ef- fective amount of the compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.

The pesticidal action of the compounds is demonstrated by the following experiments: Corn Rootworm, Wireworm and Seed Corn Maggot Seed Treatment Assay Protection of seeds from southern corn rootworm, Diabrotica undecimpunctata howardi (larvae), wireworm, Agriotis lineatus (larvae), and seed corn maggot, Delia platura (eggs) The active compounds were formulated in a solvent-surfactant carrier consisting of 15% acetone and 0.05% Tween ZOT"" (Polyoxyethylene sorbitan monolaureate) in wa- ter.

Corn seeds (corn'Truckers Favorite') were treated in lots of 50 by shaking with 450 NI of the compound preparation in a glass jar and were dried. Seeds were planted one per 120 ml container with air holes in the cap in sandy loam. Ten insect eggs or larvae were added to each container. Egg or larvae mortality and feeding damage to roots and shoots were evaluated seven days after planting.

Percent mortality of the insect and feeding damage are calculated compared to the blank solvent-surfactant control.

At 251 g active ingredient per 100 kg of seed, compounds 1-1 and i-2 provided over 30% protection of seed and seedling from wireworm feeding damage.
