Abstract:
Entomopathogenic nematodes have been used successfully in the management of insect pests. Recently they were reported to suppress plant-parasitic nematodes. Our objective was to determine if soil application of Steinernema riobrave and Heterorhabditis bacteriophora would reduce root-knot nematodes on squash. Treatments (10 replicates) included microplots with S. riobrave or H. bacteriophora at a rate of 4.5 x 10(5) nematodes/m3, 1,3-dichloropropene at 84 liters/ha, and an untreated control. One week after the treatments were applied three zucchini squash cv. Marketeer seeds were planted in each microplot. Plant stand, number of fruit, and marketable yield were higher, and root-knot nematode calling indices were lower in fumigated plots when compared to the untreated control and S. riobrave and H. bacteriophora-amended plots. Mean shoot growth in the fumigated plots was twice that of the untreated and S. riobrave and H. bacteriophora amended plots. Steinernema riobrave and H. bacteria were not effective in the management of root-knot nematodes on squash |
