The effects of plowing and tilling, fertilization, and chemical weed control on survival and height growth of newly planted seedlings of black locust, silver maple, white ash, white pine, and white spruce were investigated in a non-replicated study in southern Ontario. Cost-benefit relationships of treatments were computed. Plowing and tilling improved growth of all species with average increases ranging from 37 per cent for white spruce to 750 per cent for white ash. Plowing and tilling plus weed control greatly improved growth of all hardwood species and resulted in the most favourable growth-cost relationship. Fertilization improved growth of locust, ash, and maple by 200, 500, and 700 per cent respectively, but failed to increase conifer growth. Application of 12 pounds of simazine increased ash mortality by 67 per cent. White spruce was subject to severe frost heaving following complete weed control.

Abstract Successful establishment of hardwood plantations requires effective weed management. Mechanical weed control is inefficient, and few herbicides are available for use in hardwood plantations. In an effort to identify new chemical control options, the potential of imazapyr (Chopper herbicide) for site preparation prior to planting three common southern hardwood species was assessed. Twelve site preparation treatments were tested using Chopper applied at four rates and three timings prior to planting. Each site preparation rate and time pairing was repeated under two postplant herbicide regimes—directed glyphosate (Accord herbicide) sprays designed to maintain weed-free conditions and a single broadcast sulfometuron methyl (Oust herbicide) treatment designed to test a potential operational sequencing of Chopper site preparation followed by herbaceous weed control. Although results must be evaluated in the context of a single site and set of environmental conditions, they demonstrate the utility of Chopper herbicide for site preparation prior to planting hardwoods. For sycamore (Platanus occidentalis L.)and sweetgum (Liquidambar styraciflua L.),site preparation before the end of July with Chopper rates up to 64 oz/ac improved survival and growth over postplant treatments alone. For later season applications, sycamore and sweetgum were more sensitive to the Chopper site preparation rate. For Oct. site preparation, Chopper rates above 16 oz/ac adversely affected planted sycamore seedlings and rates greater than 32 oz/ac adversely effected planted sweetgum seedlings. Cherrybark oak (Quercus pagoda Raf.)performed best using the highest Chopper rate of 64 oz/ac regardless of timing. South. J. Appl. For. 28(3):163–170.

The herbicides paraquat, trifluralin, and metolachlor were compared for efficacy of weed control in cowpea [Vigna unguiculata (L.) Walp.] with and without cultivation as a supplemental strategy. Herbicides also were compared against a no cultivation-no herbicide treatment (control) and against cultivation without an herbicide. Cultivation had no significant effect on seed yield, biological yield, or harvest index of cowpea. Paraquat, applied before seeding but after emergence of weeds, was ineffective for weed control and usually did not change cowpea yield from that obtained without an herbicide. Trifluralin and metolachlor more than tripled cowpea seed yield compared with that obtained without an herbicide in 1988, when potential weed pressure was 886 g·m-2 (dry weight). The main effects of trifluralin and metolachlor were not significant for cowpea seed yield in 1989, when potential weed pressure was 319 g·m-2 (dry weight). However, in 1989, these two herbicides still increased cowpea seed yield compared with that of the control and increased net farm income by more than $300/ha compared with the income obtained from the control. Chemical names used 1,1'-dimethyl-4,4' -bipyridlnium salts (paraquat); 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl) benzenamine (trifluralin); 2-chloro-N-(2-ethyl-6 -methylphenyl)-N-(2-methoxy-l-methylethyl) acetamide (metolachlor).
