Application of EPTC (S-ethyl dipropylthiocarbamate) at 3.4 and 4.5 kg/ha in 1972 increased root rot severity and reduced navy bean (Phaseolus vulgaris L.) yields in soil with an artificial root rot [Fusarium solani (Mart.) Appel and Wr. f. Phaseoli (Burk.) Snyd. and Hans.] inoculum level. EPTC at 3.4 kg/ha and chloroamben (3-amino-2,5-dichlorobenzoic acid) at 3.4 kg/ha in 1973 caused the greatest root rot severity and greatest decrease in yield. Dinoseb (2-sec-butyl-4,6-dinitrophenol) and fluorodifen (p-nitrophenyl α,α,α-trifluoro-2-nitro-p-tolyl ether) at 5 kg/ha interacted with root rot less than the other herbicides assayed. In the growth chamber at 23 C, EPTC at 3.4 kg/ha and alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl) acetanilide] at 2.8 kg/ha applied to navy bean grown in soil infested with F. solani reduced plant growth. Root rot injury was most severe in plants treated with EPTC at 20 C ambient temperature. Navy bean growth was reduced as the level of F. solani chlamydospore inoculum increased in the presence of EPTC.

SummaryTwo systemic fungicides, benomyl and thiabendazole, were more active than the non-systemic fungicide Drazoxolon in inhibiting fungal growth in vitro. A similar pattern was obtained in glasshouse trials with benomyl and thiabendazole giving adequate protection at low concentrations while Drazoxolon was ineffective unless applied at 50% the commercial product concentration. A field trial using thiabendazole, Drazoxolon and a mixture of benomyl and thiram confirmed the glasshouse results.Some phytotoxicity was noticed with high concentrations of both benomyl and thiabendazole, but satisfactory disease control was achieved using fungicide concentrations which did not induce phytotoxicity.

Fusarium root rot of dry bean (Phaseolus vulgaris), caused by Fusarium solani f. sp. phaseoli, is a major yield-limiting disease in North Dakota and Minnesota. Although a few sources of partial resistance are available, most commercial cultivars grown in this region are susceptible, especially in the red kidney bean market class. This study evaluated three methods of screening for resistance to Fusarium root rot. A sand-cornmeal inoculum layer method, spore suspension method, and paper towel method were used to evaluate 11 dry bean genotypes for resistance to Fusarium root rot under growth-chamber conditions. These same genotypes were also evaluated in field trials at Fargo, ND, and Park Rapids and Perham, MN, in 2005. In all trials, the small red genotype VAX 3 was found to have a consistently high level of resistance to Fusarium root rot and could be used as a source of resistance by dry bean breeders. Correlation analyses between field and growth-chamber root rot ratings indicated that all three growth-chamber methods had significantly (P ≤ 0.05) positive correlations with field results from Perham and Fargo, which suggests that all three methods could be used to screen germplasm efficiently for resistance to Fusarium root rot.

A bean (Phaseolus vulgaris) line, A - 300, resistant to Rhizoctonia solani and Fusarium oxysporum was introduced into Ontario from Colombia. The results of tests conducted in a root-rot nursery, in a greenhouse and in a growth room showed that this bean line is resistant to Fusarium solani f. sp. phaseoli and Pythium ultimum.

Phosphatic Fertilizers

The influence of phosphate deficiencies on infection of wheat by Fusarium culmorum (W. G. Sm.) Sacc. was studied. Marquis wheat was grown in pot cultures of quartz sand with different types of manuring, including a fully manured control, and four series having deficiencies of phosphate. One-half of the pots were inoculated with F. culmorum and sown with inoculated seed, the remainder served as uninoculated controls. The plants were grown for 36 days. The experimental data were treated by the analysis of variance method.Under the conditions of the experiment, deficiencies in phosphate did not significantly increase or decrease the susceptibility of wheat plants to root rot caused by F. culmorum. On the other hand, deficiencies in phosphate significantly reduced root development and total dry weight of the plants. The results suggest that the effect of phosphatic fertilizers is much more important on plant growth and yield than on the severity of infection by F. culmorum.

Navy bean (Phaseolus vulgarisL.) seedlings grown in soil treated with EPTC (S-ethyl dipropylthiocarbamate) were more susceptible to root rot caused byFusarium solani(Mart.) Appel and Wr. f.phaseoli(Burk.) Snyd. and Hans. than were control seedlings. The navy bean line ‘RRR041,’ which is moderately resistant to root rot, did not show reduced growth when grown in soil infested withF. solaniand treated with EPTC. None of the several herbicides tested increasedF. solanichlamydospore virulence when grown on potato dextrose agar supplemented with herbicides. No herbicide tested increasedF. solanihyphal development in liquid culture or soil. Dinoseb (2-sec-butyl-4,6-dinitrophenol) reduced hyphal development by the greatest amount. Scanning electron micrographs indicated that navy bean plants grown in EPTC had altered hypocotyl surfaces. EPTC and dinoseb increased the exudation of electrolytes, amino acids, and sugars from root and hypocotyl tissue.
