  • the document corresponding to patent application CL 1549-99 relates to a method for treatment of fruit and vegetables in post-harvest conditions for the purpose of achieving their preservation; the method comprises cooling the fruit to the core and then treating it with a shower consisting of an aqueous composition for treatment by immersion, preliminary treatment of the aqueous composition with fungicide by means of thiabendazole, a terpene compound, orthophenylphenol and its salts and enilconazole, at a temperature from 40 to 6O 0 C.
