The results are presented of studies on the fungicidal action of a number of compounds (cf. C.A. 46, 7271e) on Aspergillus niger, employing the agar growth method. Most of the compounds were highly toxic to the fungus. The introduction of an addnl. Br atom imparted fair toxicity to substituted bromoamides, in contrast to the lack of toxicity of the corresponding unhalogenated amides. The dibromoamides did not, however, have exceptionally strong fungicidal activity, having only slightly more activity than the monobromoamides. The esters of cresotinic acid were fairly effective, as expected since esters of p-HOC6H4CO2H are toxic and alkyl substitution increases toxicity. The ethers of cresotinic acid esters were considerably more active than the hydroxy esters. With the higher ether-esters of cresotinic acids, a decrease in fungicidal activity occurred in compounds containing more than 12 C atoms, the hexyl ether of o-cresotinic acid butyl ester having least activity. Generally, with ether-esters of cresotinic acid the o-derivatives were less effective than the m- and p-derivatives; exceptions were noted. Substituted phenoxy fatty acids acted as fungicides at relatively low dilutions, some possessing fairly high toxicity. All of these compounds inhibited growth at a concentration of 1:10,000, maximum inhibition being exerted by p-tert-butylphenoxyacetic acid, while at 1:1,000,000 dilution, all of the compounds stimulated growth; intermediate effects were also observed. Hg derivatives of phenoxy fatty acids, especially Hg derivatives of aryloxyacetic acids, were extremely toxic to the fungus. The toxicity of most of the compounds fell rapidly as the concentration was lowered.
