Definitions

• This invention relates to agricultural and horticultural microbiocidal compositions having good stability which comprises methyl 1-(n-butylcarbamoyl)- benzimidazole-2-ylcarbamate (hereinafter sometimes referred to as "benomyl”) as a microbiocidally active ingredient.
• Benomyl is known to have excellent microbiocidal power (Japanese Patent Publn. 25720/70), and is used as a microbiocide in the agricultural and horticultural field.
• One drawback to the use of benomyl is that it decomposes with time and thus has poor storage stability. There is therefore a need for benomyl compositions which enhance the stability of benomyl.
• This invention is directed to an agricultural and horticultural microbiocidal composition consisting of a microbiocidally effective amount of benomyl and one or more compounds (hereinafter referred to as "metallic oxide”) of the general formula MxOy where M is an atom of calcium, barium, aluminum, silicon, boron or zinc, x is an integer of 1 or 2, and y is an integer of 1, 2 or 3.
• M is an atom of calcium, barium, aluminum, silicon, boron or zinc
• x is an integer of 1 or 2
• y is an integer of 1, 2 or 3.
• the metallic oxide of the claimed composition is a compound of the general formula MxOy.
• Examples include calcium oxide (CaO), barium oxide (BaO), aluminum oxide (A1 2 O 3 ), silicon dioxide (SiO 2 ), diboron trioxide (B 2 O 3 ), zinc oxide (ZnO), etc. Hydrates of metallic oxides may also be used. These metallic oxides may be blended singly with benomyl or two or more of them may be blended in admixture with benomyl.
• Benomyl and metallic oxide are preferably blended in such proportions that the latter is used in an amount of 0.01 to 10 parts by weight, preferably 0.1 to 5 parts by weight on the basis of 1 part by weight of the former.
• Preparations of the agricultural and horticultural microbiocidal composition of the present invention can be produced by mixing or grinding the above compounds by known methods. It is possible to prepare a dust, wettable powder, finely divided granule and granule by blending general adjuvants used in agricultural and horticultural chemicals as required, such as diluent, surfactant, fixing agent or the like.
• diluent one can employ finely divided mineral powders and finely divided mineral particles such as clay, talc, benzonite, diatomaceous earth or the like, a solid diluent such as white carbon or a diluent which is liquid at ordinary temperature such as ethylene glycol, polyethylene glycol, fluid paraffin, etc.
• Suitable surfactants include nonionic surfactants such as polyoxyethylene alkylaryl ether, polyoxyethylene alkyl ether, polyoxyethylene sorbitan fatty ester or polyoxyethylene fatty ester, and ionic surfactants such as alkylaryl sulfonate, alkylsulfate, fatty acid salt, ligninsulfonate, naphthalene sulfonate or alkylamine salt.
• the fixing agent one can use a solid paraffin, a vinyl acetate resin, natural fats and oils, etc.
• Other natural or synthetic products may also be included in the composition of this invention such as stabilizers, microbiocides, insecticides, herbicides, plant growth regulators, extenders, attractants, repellants, fertilizers, perfumes, colorants, and physical modifiers.
• microbiocides and insecticides which can be blended with the benomylmetallic oxide composition of this invention: copper type microbiocides such as cupric hydroxide and 8- quinolinol copper; organic sulfur type microbiocides such as zinc ethylene-bis(dithiocarbamic acid), manganese ethylene-bis(dithiocarbamic acid), zinc-maneb complex compound, zinc dimethyldithiocarbamate, dimethyl 4,4-o-phenylene-bis(3-thioallophanic acid) and bis(dimethylthiocarbamoyl)disulfide; or organic chlor ine type microbiocides such as tetrachloroisophthalonitrile, N-(parafluorophenyl)dichloromaleimide, 4,5,6,7-tetrachlorophthalide and pentachlorophenyl organic phosphorous type microbiocides such as S-benzyl-0,0-diisopropyl thi
• the storage and application methods of the agricultural and horticultural microbiocidal composition of this invention are the same as those for conventional preparations containing benomyl.
• compositions of this invention are advantageous in that they can be stored for long periods of time without losing their microbiocidal effectiveness.
• Example 7 wettable powder
• benomyl There are mixed 20 parts of benomyl, 40 parts of manganese ethylene-bis(dithiocarbamic acid), 2 parts of calcium oxide, 3 parts of sodium dodecylbenzenesulfonate, 5 parts of calcium ligninsulfonate and 30 parts of clay.
• the resultant mixture is then ground to afford a wettable powder.
• the resultant mixture is then ground to prepare a wettable powder.
