Three field trials were conducted to determine the efficacy of fumigant and herbicide combinations on nematode and Cyperus control in bell pepper (Capsicum annuum L.). Various in-bed, broadcast and drip-applied fumigants were combined with napropamide, trifluralin, and a non-herbicide treated control. Results indicated that during all the three bell pepper seasons, metham sodium plus chloropicrin (MNa +Pic), and both the gas and emulsifiable formulations of 1,3-dichloropropene (1,3-D) plus Pic provided equal or better Meloidogyne control than methyl bromide (MBr) plus Pic. For Heterodera and Belonolaimus control, MNa + Pic and both formulations of 1,3-D + Pic were equally effective as MBr + Pic during the three bell pepper trials. For Cyperus control, the herbicides failed to improve weed control. For the fumigants, MBr + Pic consistently controlled the weed better than the others. However, most of the MBr alternatives reduced Cyperus populations with respect to the non-fumigant control. For bell pepper yield, the application of MNa and MNa + Pic provided similar fruit weight as for MBr + Pic in two of the three seasons. (c) 2005 Elsevier Ltd. All rights reserved.
