  The present invention is based on the discovery of the extremely potent fungicidal action possessed by certain

  
 <EMI ID = 1.1>

  
In main patent no. 537,420, the remarkable anti-cryptogamic action exerted by 1-chloro-2.4dinitronaphtha.lene has been described. By carrying out subsequent research, the Applicant has found that fungicidal compounds with an activity equal to or often greater than that of

The new fungicides which are the subject of the present invention can be employed in various forms which

the concentration of active material at the usual values. The diluent can be an inert solid, for example, talc, pyrophyllite, bentonite or diatomaceous earth. Biologically active substances can also be used as diluents, for example, insecticides (DDT, dieldrin, lindane), hormones (indole butyric acid) or fungicides
(sulfur, copper oxychloride, ethylene bis-zinc dithiocarbamate). It is advantageous to apply these anticryptogamics in the form of a suspension in water, in which case suitable wetting and dispersing agents are added to the solid composition described above. The wetting agents used can be nonionic, cationic, or anionic. For example, we can use

  
 <EMI ID = 15.1>

  
Usable include alkyl-aryl-sulfonates, ex. Santomerse D, a decylbenzene sulfonate, higher alcohol sulfates,
