Abstract:

Selected systemic insecticides (carbofuran, disulfoton, Dasanit® (O, O-diethyl O-[p-(methylsulfinyl)phenyl]phosphorothioate), and Dasanit + disulfoton, phorate, and aldicarb) were tested as granules in-furrow during 1970 and 1971. These materials were applied to 'Lee 68' soybeans at 0.91 and 1.82 Ib AI/acre.

In 1970, Dasanit + disulfoton at 0.91 Ib/acre produced the tallest plants during the 1st month of plant growth. Dasanit at 1.82 lb/acre retarded plant growth more than any treatment or the check in 1970. Significant differences were seen between treatments and between treatments and the check on each of the 4 dates height measurements were taken in 1970. In 1971, no material significantly affected plant height. Dasanit 0.91 lb/acre significantly increased pod height on the stem over that of the check in 1970. In 1971, carbofuran differed significantly in height of 1st pod on the stem from disulfoton at 1.82, Dasanit at 0.91, and aldicarb at 1.82 Ib/acre. Statistical analysis of yield data and weight of 100 seed samples detected no significant differences between insecticide treatments and the untreated check either year.
