The present invention relates to new substituted 1, 2, 3, 4-tetrahydro-5-nitro-pyrimidines of the formula (I) ##STR1## wherein Het, R.sup.1, R.sup.2, R.sup.3 and A are as defined herein,to processes for their preparation, and to their use as pesticides and ectoparasiticides.
摘要:
The invention relates to an aqueous dispersion which includes a mixture composed of the active ingredients carbendazime, 2-(thiocyanomethylthio)-benzothiazole and 2-methylthio-4-t-butyl-amino-6-cyclopropylamino-s-triazine. Further active ingredients with algicidal or fungicidal effect can optionally be present in the dispersion. The dispersion can be used for the fungicidal and algistatic finishing of paints, varnishes and plasters.
摘要:
This invention provides a surprisingly efficacious combination useful for inhibiting microorganism growth, particularly in aqueous slurries containing mineral ore. In particular embodiments, the invention provides an antimicrobial composition comprising 1-(3-chloroallyl)-3,5,7 triaza-1-azoniaadamantane chloride and 2-bromo-2-nitropropane-1,3-diol. The invention also provides a method for inhibiting microbial growth in an aqueus mineral or ore slurry, e.g. a kaolin slurry. The method includes the step of adding to the slurry a microbiocidal composition of 1-(3-chloroallyl)-3,5,7 triaza-1-azoniaadamantane chloride and 2-bromo-2-nitropropane-1,3-diol.
