THE POTENTIAL FOR MANAGING ROOT-KNOT NEMATODES BY USE OF PASTERURIA PENETRANS AND OXAMYL

Abstract

The use of Pasteuria penetrans and oxamyl singly and in combination for the control of Meloidogyne javanica infecting two tomato cultivars was tested under glasshouse conditions. Treatments significantly decreased the number of egg masses produced on cvs. Tiny Tim and Moneymaker compared with the untreated controls. On Moneymaker, egg production was greater in the combined treatments despite there being fewer egg masses. The relationship between the egg masses produced in a root system and the number of eggs per egg mass was negatively correlated.
