Root Knot Nematode..
Over the past few years we have seen an increased level of root knot nematode infestation in the veggie patch.. This is due to poor crop rotations, spreading contaminated soil through transplanting & reusing old soil in new beds.. There are some plant varieties, especially in the Fabaceae family that includes peas & beans, have root nodules.. These are caused by a beneficial bacteria, called rhizobia, that form a symbiotic relationship with the plants helping them to fix nitrogen from the atmosphere to the soil..
