A METHOD OF CONTROLLING THE GROWTH OF NEMATODES AND BACTERIA IN SOIL WHICH COMPRISES APPLYING THERETO A NEMATOCIDAL AND BACTERICIDAL AMOUNT OF A COMPOSITION COMPRISING AN INERT PESTICIDAL CARRIER MATERIAL AND, AS THE ESSENTIAL ACTIVE INGREDIENT, A MATERIAL SELECTED FROM THE CLASS CONSISTING OF 3,6-DITHIAOCTANE, 3,6,9-TRITHIAUNDECANE, AND THE REACTION PRODUCTS OBTAINED BY HEATING ONE OF SAID THIAHYDROCARBONS WITH ELEMENTAL SULFUR AT A TEMPERATURE BETWEEN ABOUT 100*C. AND ABOUT 250*C. FOR A PERIOD OF TIME BETWEEN ABOUT 1 AND ABOUT 24 HOURS, BETWEEN ABOUT 1 AND ABOUT 10 ATOMIC WEIGHTS OF SULFUR BEING EMPLOYED PER MOLECULAR WEIGHT OF SAID THIAHYDROCARBON AND SAID CONDITIONS OF TIME AND TEMPERATURE BEING SUFFICIENT TO EFFECT THE FORMATION OF A SULFURIZED THIAHYDROCARBON CONTAINING FROM 1 TO AN AVERAGE OF ABOUT 10 ATOMS OF SULFUR PER MOLECULE OF SAID THIAHYDROCARBON REACTANT.
