Phytopathology. 92(Suppl.6):17. Interpretive Summary: Technical Abstract: Field plots were established 8 Aug 2001 on a Tifton loamy sand naturally infested with Meloidogyne incognita. The experiment was a randomized complete block design with polyethylene film mulch beds 7.6 m long and 0.76 m wide replicated 5 times. Blue dye was injected into the drip tape to estimate movement of oxamyl in the soil. Treatments were methyl bromide (MB) 224 kg/h; 1,3-D; 1-3-D plus oxamyl 0, 2 and 4 wks post plant (pp); 1,3-D plus oxamyl 2, 4 and 6 wks pp; oxamyl 0, 2 and 4 wks pp; oxamyl 2, 4 and 6 wks pp; 1,3-D plus oxamyl 4, 6, 8 wks pp; oxamyl 0, 2 and 4 wks pp; and control. All 1,3-D was applied at 76 1/ha by chisel injection 46 cm deep. All oxamyl was applied at 4.67 1/ha per application via drip tape. Cucumber weight was increased by the MB and 1,3-D + oxamyl 2, 4 and 6 weeks pp treatments. Numbers of cucumbers were increased by all treatments except those which received only oxamyl. Numbers of M. incognita juveniles and the root gall index observed at harvest were decreased by all treatments except oxamyl alone. MB and 1,3-D treatments reduced colony forming units of Pythium spp. at planting and at harvest. |
