Principles of Nematology (Gerald Thorne, 1961):

"It is fitting that a few words of commendation be given to the officials of the Shell Chemical Corporation and The Dow Chemical Company for their foresight in pioneering the field of soil fumigation. Their efficient, generous, cooperative, and persistent campaigns have carried the science of soil fumigation into almost every country. Those of us who had spent many years attempting to control nematodes by crop-rotation and cultural methods, often with futile, discouraging results, now realized the satisfaction of recommending D-D and EBD for the control of nematodes on certain moderate and high-priced crops."
