greenhouse, and 2) confirm that the MSM rates used in our study inhibit emergence of a weed (Palmer amaranth, Amaranthus palmeri ) and growth of a soilborne pathogen ( Phytophthora capsici ) that are common problems during the middle and later phases of
Growth of `Apache' pecan [Carya illinoinensis (Wangenh.) K. Koch] seedlings was evaluated for 3 years when grown in a 11.2-m2 weed-free area or when various combinations of one or two plants of cutleaf evening primrose (Oenothera laciniata Hill), a cool-season species, or Palmer amaranth (Amaranthus palmeri S. Wats.), a warm-season species, were grown 30 cm from the tree, with the rest of the 11.2-m2 area weed-free. Either weed species alone suppressed tree growth compared to the weed-free control. A temporal succession of primrose followed by amaranth reduced growth most. After 3 years, two plants of primrose followed in succession by two of amaranth caused a 79% reduction in cumulative current-season's growth.
the following eight plant species: Penstemon palmeri (Palmer penstemon), Mirabilis multiflora (desert four o'clock), Geranium viscosissimum (sticky geranium), Eriogonum jamesii (James buckwheat), Echinacea purpurea (purple coneflower
L.), and Palmer amaranth ( Amaranthus palmeri S. Watts). Yellow and purple nutsedge affect sweetpotato yield and quality negatively, and are the most difficult-to-control weeds in sweetpotato across the Southeast because of the high rainfall
