The Root Knot disease of tomatoes and cucumbers, caused by the attacks of Heterodera radicicola Müll., is of widespread occurrence and under certain conditions, notably in the presence of fungi, may cause serious losses. Under some conditions considerable infestation may be present and yet produce no apparent ill-effects on the plants.
Experiments having indicated that sodium cyanide was beneficial in reducing the amount of eelworm infestation and pot trials having suggested that calcium cyanide might also prove effective, trials with calcium cyanide were carried out at various centres in 1926 and 1927.
