Abstract: Research was conducted in North Carolina to compare tobacco thrips (Frankliniella fusca Hinds) control, early season peanut emergence and growth, and pod yield with combinations of the insecticide acephate, inoculant containingBrady rhizobium, and the fungicide tebuconazole applied in the seed furrow during planting. Although interactions among treatment factors were significant, greater control of tobacco thrips damage was noted when acephate was applied and in some cases when tebucanozole was applied. Tebucanzole-treated peanut emerged more slowly than peanut not receiving tebucanazole. Delayed emergence of tebuconazole-treated peanut most likely resulted in emergence when fewer tobacco thrips were present in fields. Peanut pod yield was affected by acephate, inoculant, and tebuconazole independently. Applying acephate and inoulcant increased pod yield in two and three of five experiments, respectively. Pod yield was lower in one of five experiments when tebuconazole was applied. These data suggest that while acephate, inouclant, and tebuconazole may interact with respect to early season tobacco thrips control, these in-furrow materials most likely will affect pod yield independently.
