Specific growth rate constants were used to evaluate the effects of selected herbicides on Erwinia carotovora, Pseudomonas fluorescens, and Bacillus sp. Comparison of growth rate constants permitted the identification of either stimulatory or inhibitory effects of these substances. E. carotovora was inhibited by 6,7-dihydrodipyrido(1,2-a:2'-c)pyrazinediium (diquat) and 4-hydroxy-3,5-diiodobenzonitrile (ioxynil) at 25 mug/ml; 1,1'-dimethyl-4,4'-bipyridinium (paraquat) at 50 mug/ml; and pentachlorophenol (PCP) at 10 mug/ml. P. fluorescens was inhibited by paraquat and PCP at 25 mug/ml and by 4-amino-3,5,6-trichloropicolinic acid (picloram) at 50 mug/ml. Stimulation of P. fluorescens was observed with 4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline (nitralin) at 25 mug/ml. The Bacillus species was inhibited by diquat (25 mug/ml), ioxynil (10 mug/ml), and paraquat and PCP (5 mug/ml). No significant effect of 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine), 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron), alpha,alpha,alpha-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin), or 1,1-dimethyl-3-(alpha,alpha,alpha-trifluoro-m-tolyl)urea (fluometuron) on growth rates of the bacteria was observed at 25 and 50 mug/ml.
特定生长速率常数用于评估所选除草剂对胡萝卜软腐欧文氏菌、荧光假单胞菌和芽孢杆菌属的影响。通过比较生长速率常数，可以确定这些物质的刺激或抑制作用。胡萝卜软腐欧文氏菌在25微克/毫升的6,7-二氢二吡啶并(1,2-a:2'-c)吡嗪二鎓（敌草快）和4-羟基-3,5-二碘苯腈（碘苯腈）、50微克/毫升的1,1'-二甲基-4,4'-联吡啶鎓（百草枯）以及10微克/毫升的五氯苯酚（PCP）作用下受到抑制。荧光假单胞菌在25微克/毫升的百草枯和PCP以及50微克/毫升的4-氨基-
3,5,6-三氯吡啶甲酸（毒莠定）作用下受到抑制。在25微克/毫升的4-(甲基磺酰基)-2,6-二硝基-N,N-二丙基苯胺（氟乐灵）作用下观察到荧光假单胞菌受到刺激。芽孢杆菌属在25微克/毫升的敌草快、10微克/毫升的碘苯腈以及5微克/毫升的百草枯和PCP作用下受到抑制。在25和50微克/毫升浓度下，未观察到2-氯-4-(乙氨基)-6-(异丙氨基)-s-三嗪（莠去津）、3-(3,4-二氯苯基)-1,1-二甲基脲（敌草隆）、α,α,α-三氟-2,6-二硝基-N,N-二丙基对甲苯胺（氟乐灵）或1,1-二甲基-3-(α,α,α-三氟间甲苯基)脲（伏草隆）对细菌生长速率有显著影响。
