Claim Text:
1. A method of treating soils to eradicate or reduce the number and/or proliferation of plant parasitic nematodes, said method comprising applying a nematicide comprising a nematicide active to the soil to be treated, said nematicide active comprising i) at least one antimicrobial metal ion or ion source which releases the antimicrobial metal ion in the presence of an acidic solution and ii) at least one organic acid, and optionally, iii) at least one surfactant which a) enhances penetration of the nematicide actives into the soil, b) enhances the bioefficacy of the nematicide actives as compared to the same nematicide actives without the surfactant, or c) both or d) a combination of such surfactants, wherein the at least one acid is present in an amount of at least 20 weight percent based on the combined weight of the acid and metal ion source and the mole ratio of acid to metal ion is at least 0.3:1, said nematicide having a pH of from about 1.5 to about 12; provided that when the nematicide is to be applied to soils in which planting has already taken place, the pH is from about 5 about 12, or the acid is sufficiently weak as not to cause phytotoxicity, wherein the nematicide does not comprise additional nematicidally active ingredients in a nematicidally effective amount.
