The invention comprises the compounds of formula <FORM:1065589/C2/1> wherein R is H or C2H5. The compounds are used in fungicidal compositions (see Division A5). In examples: (1) 3-(2-benzthiazolyl)-1-ethylurea is prepared by condensing 2-aminobenzothiazole with ethyl isocyanate; (2) 3 - (2 - benzthiazolyl) - 1,1 - diethylurea is prepared by reacting 2-aminothiophenol with diethylcarbamoyl isothiocyanate.ALSO:Fungicidal compositions comprise a biologically inert carrier and a fungitoxic quantity of a compound of formula <FORM:1065589/A5-A6/1> wherein R is H or C2H5. The compositions may be in spray emulsion, vapour, wettable powder or dust form. Specified solid carriers are fullers earth, pyrophyllite, talc, bentonite, Kieselguhr or diatomaceous earth. Specified liquid carriers are water, kerosene, fuel and lubricating oils and soy bean oil, linseed, castor, sperm and cod liver oils. Specified wetting agents are fatty alcohol sulphates, aliphatic or aromatic sulphonates and alkyl polyglycol ethers or thioethers. In examples the use of aqueous solutions or suspensions of the compounds in controlling fungus attack on beans, cucumbers, tomatoes, beans and roses is described. |
