The compounds of general formula (V) and (VII) can be easily prepared by reaction of the general formula (IV) and (VI), respectively, with methylamine aqueous solution.

The present invention also provides a composition of insecticides and fungicides. The active ingredients of the composition are the compounds having general formula (I), wherein the active ones being present in a total amount of 0.1 to 99% by weight, the rest being the acceptable carrier by agriculture.

The present invention, further more, provides preparation method of the said composition thereon. The compounds of general formula (I) and the carrier are mixed. The said composition may be a single component compound or mixture of compounds with several components.

The carrier in the invention accords to the requirements: it is easy to apply to the sites being to be treated for the carrier after it is confected with active component. For example, the sites could be plant, seed or soil convenient for store, transport or operation. The carrier could be solid or liquid, including the liquid which usually turns from gas condition under pressure. And the carriers which are used to confect insecticidal, bactericidal composition are applied.

Suitable solid carriers include natural and synthetic clays and silicates, for example diatomaceous earths, talcs, magnesium aluminium silicates, aluminium silicates(kaolin), montmorillonites and micas; calcium carbonate; calcium sulphate; ammonium sulphate; synthetic silicon oxides and synthetic calcium silicates or aluminium silicates; elements, for example carbon and sulphur; natural and synthetic resins, for example coumarone resins, polyvinyl chloride, and styrene polymers or copolymers; solid polychlorophenols; bitumen; waxes, beeswax or paraffin wax for instance.

Suitable liquid carriers include water, alcohols such as isopropanol or alcohol; ketones such as acetone, methyl ethyl ketone, methyl isopropy ketone or cyclohexanone; ethers; aromatics such as benzene, xylene, toluene; petroleum fractions such as kerosene or mineral oils, chlorinated aliphatic hydrocarbons such as carbon tetrachloride, tetrachloride ethylene or trichloride ethylene. Mixtures of these different liquids generally are often suitable.

The compositions of insecticides and fungicides are often formulated and transported in a concentrated form which is subsequently diluted by the user before application. The presence of small amounts of surfactant facilitates this process of dilution. Thus preferably at least one carrier in a composition according to the invention is a surfactant. For example the composition may contain at least two carriers, at least one of which is, a surfactant.

A surfactant may be an emulsifier, a dispersant or a wetting agent; it may be nonionic or ionic. Examples of suitable surfactant include the sodium or calcium salts of polyacrylic acids and lignin sulphonic acids; the condensation products of fatty acids or aliphatic amines or amides containing at least 12 carbon atoms in the molecule with ethylene oxide and/or propylene oxide; fatty acid esters of glycol, sorbic alcohol, sucrose or pentaerythritol and condensations of these with ethylene oxide and/or propylene oxide; condensation products of fatty alcohol or alkyl phenols such as p-octylphenol or p-octylcresol, with ethylene-oxide and/or propylene oxide; sulphates or sulphonates of these condensation products; alkaline metal salts or alkaline earth metal salts, preferably sodium salts, of sulphuric or sulphonic acid esters containing at least 10 carbon atoms in the molecule, for example sodium lauryl sulphate, sodium secondary alkyl sulphates, sodium salts of sulphonated castor oil, and sodium alkylaryl sulphonates such as sodium dodecylbenzene sulphonate.

Examples of compositions and formulations according to the invention are wettable powder, Dustable powder, granule and aqueous solution; emulsifiable concentrate, emulsion, suspension concentrate, aerosol composition and fumigant. Wettable powder usually contains 25, 50 or 75% weight(ab.w) of active ingredient and usually contain in addition to solid inert carrier, 3-10% w of a dispersant and, where necessary, 0-10% w of stabiliser(s) and/or other additives such as penetrants or stickers. Dustable powder are usually formulated as a dust concentrate having a similar composition to that of a wettable powder but a dispersant, and are diluted with further solid carrier to give a composition usually containing 0.5-10% weight of active ingredient. Granules are usually prepared to have a size between 10 and 100 BS mesh (1.676-0.152 mm), and may be manufactured by agglomeration or impregnation techniques. Generally, granules contain 0.5-75% w active ingredient and 0-10% weight of additives such as stabilisers, surfactants, slow release modifiers. The so-called “dry flowable powders” consist of relatively small granules having a relatively high concentration of active ingredient. Emulsifiable concentrates usually contain, in addition to a solvent and, when necessary, co-solvent, 1-50% weight /volume(ab. w/v) active ingredient, 2-20% w/v emulsifiers and 0-20% w/v of other additives such as stabilisers, penetrants and corrosion inhibitors. Suspension concentrates are usually contain 10-75% w active ingredient, 0.5-15% w of dispersing agents, 0.1-10% w of other additives such as defoamers, corrosion inhibitors, stabilisers, penetrants and stickers.

Aqueous dispersant and emulsions, for example compositions obtained by diluting a wettable powder or a concentrate according to the invention with water, also lie within the scope of the invention. The said emulsions may be of the water-in-oil or of the oil-in-water type.

The composition to which one or more other fungicides are added has wider spectrum activity than single compound having general formula (I). In addition, other fungicides may have synergistic effect on the fungicidal activity of the compound having general formula (I). The compound having general formula (I) can also be used with other insecticides, or with another fungicide and other insecticides simultaneously.

This invention has the following advantages:

The compounds of present invention have very good insecticide activity, and may be used to control insects such as armyworm, diamond backmoth, aphids, carmine spider mite, two-spotted spider mite, lady beetles, mites and culex mosquitoes, especially for lady beetles and culex mosquitoes. All these attributes are suitable for integrated insect management.

The compounds of present invention have wide spectrum fungicidal activity, and may be used to control diseases in all sorts of plants caused by by oomycete, basidiomycete, ascomycete pathogens, and it may also provide good control efficacy at very low rate because of the high activity. These compounds have penetration activity and can be used as soil and foliar fungicides. They can provide satisfied control of grape downy mildew, rice sheath blight, rice blast, tomato early blight, tomato late blight, wheat leaf rust, wheat leaf blotch, wheat powdery mildew, cucumber powdery mildew, cucumber downy mildew and cucumber grey mold
