Biological warfare in the soil is being encouraged through a product containing parasitic nematodes for the control of damaging soil pests such as weevils
Biological warfare in the soil is being encouraged through a product containing parasitic nematodes for the control of damaging soil pests such as weevils. The product, Nemasys, has just come onto the market in Britain. The nematode, Steinernema bibionis, is a species completely unrelated to those nematodes which infect plants or mammals. When applied to the soil, they seek out and enter the body of the target pest. The nematodes carry with them a bacterium which is deadly to many insects and their larvae and, once in the body of the prey the bacteria are quickly released. The nematode feeds on the bacteria and multiplies to produce many ok-spring, which in turn move out of the insect's body and seek out new victims. This product has been developed to control the vine weevil which is a particular pest of ornamental plants in glasshouses. However the expertise developed by the Agricultural Genetics Company and the Institute of Horticultural Research will be used to identify other strains of nematodes which will be effective in the control of other pests, especially those of brassicas. In trials carried out over the last year, Nemasys was more effective than chemical insecticides in keeping soil free of the vine weevil over the four-six month growing season.
