This article reports results of trials with a systemic experimental nematocide, du Pont's 1410, chemically identified as S-methyl 1-(dimethylcarbamoyl)-N-[(methyl-carbamoyl)oxy]thioformimidate (D-1410). When D-1410 was released for testing, evidence was presented that demonstrated its systemic activity. Trials reported here have shown that when D-1410 is sprayed on plant foliage, it—or one of its breakdown products—is translocated to the roots and controls plant-pathogenic nema-todes.

Dr. George McCall of the du Pont Company provided assistance with these tests.
