摘要:
An insecticidal and/or acaricidal and/or nematicidal composition having a rapid efficacy and residual activity which comprises a mixture of a poorly water-soluble organophosphorus insecticide and/or acaricide and/or nematicide and/or a poorly water-soluble carbamate insecticide and/or acaricide which have been microencapsulated in water-insoluble polymer coatings with a dispersing agent used in forming a microcapsule part, with a poorly water-soluble pyrethroid insecticide and/or acaricide emulsified or suspended in water with the above-mentioned dispersing agent used in forming a flowable part.
摘要:
A microencapsulated insecticidal composition has excellent residual effect which comprises an organophosphorus insecticide encapsulated in a wall formed of a polyurea and having an average particle diameter of not more than 80 .mu.m, a wall thickness of not more than 0.3 .mu.m and a ratio of an average particle diameter/wall thickness of not less than 250.
摘要:
A solid pesticidal formulation, such as wettable powders, water dispersible granules and water soluble formulations, enveloped in a water soluble substance, such as polyvinyl alcohol and so on, wherein the solid pesticidal formulation comprises at least one water soluble hydroxy compound selected from the group consisting of alkanols, alkylene glycols, glycol monoethers, tri- or more valent alcohols, alcoholamines, hydroxyfatty acids and hydroxyfatty acid esters, or water soluble glycol ether acetates is excellent in stability after preserved.
摘要:
An aqueous suspension formulation of encapsulated pesticide comprising 3 to 30% by weight of nonionic water-soluble substance which is a solid at room temperature and has 50 to 700 of molecular weight is easy to handle, excellent in preservative stability and highly antiseptic.
摘要:
The water dispersible granule of the present invention is obtained by mixing a pesticide having a melting point of not more than 70.degree. C., a calcined product of precipitated hydrated silicon dioxide and a surface active agent, and granulating the resulting mixture by the wet granulation method or compaction method. This water dispersible granule is an excellent formulation of which the physical properties such as disintegrability-in-water, dispersibility, suspensibility, storage stability, etc. are good, and which is free from dust-scattering and is capable of being measured by volume.
摘要:
A pesticidal composition comprising microcapsules, each microencapsulating an organophosphorus compound having a melting point of at least 15.degree. C., a proportion (A) of aromatic ring structure in microcapsule wall material being not more than 40% by weight, and a ratio of (A) to (average diameter/wall thickness) of the microcapsules being not less than 0, but not more than 0.8, causes less color change to applied area even if applied outdoors.
摘要:
A liquid pesticidal composition including Acephate and one or more N-alkyl-2-pyrrolidones, and methods for stabilizing and inhibiting decomposition of Acephate by adding one or more N-alkyl-2-pyrrolidones to Acephate. The storage stability of Acephate bulk or Acephate in an Acephate-containing liquid pesticidal composition is improved by addition of the N-alkyl-2-pyrrolidone(s).
摘要:
A composition excellent in dispersibility and diffusion in water, and storage stability comprising a) a pesticidal active ingredient, b) a surface active agent, c) a carbonate, d) a solid acid and e) at least one selected from the group consisting of boron oxide and metaboric acid, wherein at least one of the carbonate and the solid acid is water-soluble, the total content of the carbonate and the solid acid is in a proportion of 5-90% to the total weight, the weight ratio of the carbonate to the solid acid is in the range of 1:10-10:1, and the weight of at least one selected from the group consisting of boron oxide and metaboric acid is in a proportion of 0.5-40% to the total weight.
