Effect of three nematicides on the growth of some phytopathogenic bacteria and fungi.
The effect of three nematicides, aldicarb, fensulfothion, and phenamiphos at four concentrations (1, 5, 25, and 125 ppm) was tested on the growth of five bacteria, Agrobacterium tumefaciens, Corynebacterium fascians, Erwinia carotovora, Pseudomonas solanacearum, and Streptomyces scabies and four fungi, Fusarium oxysporum f. sp. vasinfectum, Fusarium solani, Rhizoctonia solani, and Sclerotium bataticola. Of the bacteria, P. solanacearum was most affected by the chemicals at all concentrations, while E. carotovora was least affected. Fensulfothion was generally the most effective nematicide on the bacteria tested, while phenamiphos was the least effective. Similarly, the effect of the chemicals on the fungi tested varied greatly. F. solani and R. solani were generally most affected, followed by F. oxysporum, while S. bataticola was least affected. Of the chemicals tested, phenamiphos was generally the most effective, followed by fensulfothion, while aldicarb was the least effective.
