Root knot nematodes, which are serious pests of many vegetable crops, can be controlled by soil bacteria. When infected soils are inoculated with the bacteria, vegetable yields are significantly increased. On many islands in the South Pacific, families have had to give up growing vegetables, because of damage by root knot nematotes. Researches from Reading University, UK, looking for a simple solution, identified Pasteuria penetrans, a bacterium specific to the root knot nematode. But it is difficult to culture, except through the nematodes. Mass production was impossible for large areas, but on small vegetable areas it was thought that numbers could be built up. The bacteria were taken to Tuvalu, where some infected plots were inoculated. Vegetable yields from treated plots proved significantly heavier. Now the researchers are hoping that the vegetable roots from the treated plots can be used to increase the population of bacteria. Roots can be dug up, dried, and then dug in once again. Drying in the sun kills the root knot nematodes, but the bacteria appear to be resistant to ultra violet light. This simple low-cost treatment may offer a practical means of multiplying the bacteria at the farm level.
