The compounds having general formula I, which is exerted with respect to the adults, larvae and eggs of mites and insects which are harmful in the agricultural, have a high acaricidal and insecticidal activity, while the compounds also exhibit preferably fungicidal activity.
A further object of the present invention therefore relates to the use of the compounds having general formula I as acaricides, insecticides, and fungicides, both in agriculture and other fields. In particular, the compounds having general formula I are active against important species of tetranychidae (Tetranychus urticae, Tetranychus cinnabarinus, Panonychus ulmi, Panonychus citri, etc.), eriophyidae, tarsonemidae, etc. Additionally, some compounds in present invention also exhibit good fungicidal activity, which can be used to control of rice blast, tomato late blight, cucumber downy mildew, cucumber anthracnose, corn rust, wheat powdery mildew etc.
At the same time, the compounds having general formula I have a low toxicity with respect to many useful insects and mites, mammals, fish, birds, and have no phytotoxicity.
Thanks to their positive characteristics, they can be advantageously used in defending not only crops of agrarian and horticultural interest, but also domestic and breeding animals, as well as environments frequented by human beings, from harmful mites and insects.
For obtaining the desired effect, the quality of compounds can be varied in relation to various factors such as, the compound used, the crop to be preserved, the type of harmful organism, the degree of infestation, the climatic conditions, the method of application, the formulation adopted.
Doses of compounds ranging from 10 g to 5 kg per hectare generally provide a sufficient control.
A further object of the present invention also relates to a method for controlling mites and/or insects and/or phytopathogenic fungi in crops of agrarian and horticultural interest and/or on domestic and breeding animals and/or environments frequented by human beings, by the application of the compounds having general formula I. In particular, the quantity of compounds to be applied varies from 10 g to 5 kg per hectare.
For practical application in agriculture, it is usually beneficial to use compositions containing one or more compounds having general formula I.
A further object of the present invention therefore relates to acaricidal, insecticidal and fungicidal compositions containing compounds having general formula I as active principle and acceptable carrier in agriculture, the active component of the compositions is 0.5-90%.
Compositions can be used in the form of dry powders, wettable powders, emulsifiable concentrates, microemulsions, pastes, granulates, solutions, suspensions, etc.: the selection of the type of compositions depends on the specific application.
The compositions are prepared in the known way, for example by diluting or dissolving the active substance with a solvent medium and/or a solid diluent, optionally in the presence of surfactant
Solid diluents, or carriers which can be used are, for example: silica, kaolin, bentonite, talc, diatomite, dolomite, calcium carbonate, magnesia, chalk, clays, synthetic silicates, attapulgite, sepiolite.
Liquid diluents which can be used are, for example, besides water, aromatic organic solvents (xylols or mixtures of allylbenzols, chlorobenzene, etc.), paraffins (petroleum fractions), alcohols (methanol, propanol, butanol, octanol, glycerin, etc.), esters (ethyl acetate, isobutyl acetate, etc.), ketones (cyclohexanone, acetone, acetophenone, isophorone, ethylamylketone, etc.), amides (N, N-dimethylformamide, N-methylpyrrolidone, etc.).
Surfactant which can be used are salts of sodium, calcium, triethylamine or triethanolamine of alkylsulfonates, alkylarylsulfonates, polyethoxylated alkylphenols, polyethoxylated esters of sorbitol, ligninsulfonates, etc.
The compositions can also contain special additives for particular purposes, for example adhesive such as Arabic gum, polyvinyl alcohol, polyvinyl-pyrrolidone, etc.
The concentration of active principle in the above compositions can vary within a wide range depending on the active compound, the applications for which they are destined, the environmental conditions and the type of formulation adopted. In general the concentration of active principle ranges from 1 to 90%, preferably from 5 to 50%.
It is possible to add to the compositions, other active principles compatible with the compounds having general formula I according to requirement, such as, for example, other acaricides/insecticides, fungicides, phytoregulators, antibiotics, herbicides, fertilizers.
Several formulations of preparation methods, for example as follows:
The preparation of suspension concentrate: the common active component in formula is 5%-35%. With water as the medium, the compound, dispersing agent, suspending agent and antifreeze agent are added to sanding machine for grinding to make suspension concentrate.
The preparation of water emulsion: the compound, solvent and emulsifier are mixed together, to make a homogeneous oil phase. The water is mixed with antifreeze, as a homogeneous water phase. In the high-speed stirring, the aqueous phase added to the oil phase or oil phase is added to the aqueous phase, forming a good dispersion of the water emulsion. The active component of emulsions is generally 5%-15% in this invention. For the production of concentrated emulsions, the compounds of this invention are soluble in one or more of the mixed solvent, and then emulsifier is added to enhance dispersion effects in the water.
The preparation of wettable powder: the compound, surfactants and solid diluent are mixed well according to recipe requirements, after smashing through ultrafine pulverizer, that is the wettable powder products (for example, 10%-40%). For preparing the spraying wettable powder, the compounds of this invention can be mixed with solid power to form the mixture, such as clay, inorganic silicates, carbonates, as well as wetting agents, adhesives and/or dispersant agent.
The preparation of water dispersible granules: the compound and powdered solid diluents, wetting agents and adhesives are mixed to smash, kneaded together with water and added to the granulation 10-100 mesh machine for granulation, then by drying and sieving (at the scope screen). Also, the compounds, dispersants, wetting agents, disintegrants and solid diluent are added sanding machine, grinded with water for medium to produce suspension and then spray-drying granulation, usually the preparation of content is 20%-30% granular products.
