Photoperiodic control of floral initiation in
sicklepod (Cassia obtusifolia L.).
Sicklepod (Senna obtusifolia) response to shading, soybean (Glycine max) row spacing, and population in three management systems.
In another experiment increasing soybean density from 245,000 plant/ha to 481,000 and 676,000 plants/ha with reduced row distance reduced
sicklepod (Senna obtusifolia L.) density and growth [23].
Lynn Walker provided him with isolates from diseased sicklepod plants.
Besides kudzu and sicklepod, Myrothecium attacks hemp sesbania--which is problematic in soybean crops of the southeastern United States--morningglories, pigweed, redvine, and trumpetcreeper.
Bromoxynil controls several troublesome weed species encountered in cotton production, including morning-glory (Ipomoea spp.) and cocklebur (Xanthium strumarium L.), but is mostly ineffective at controlling grasses, pigweed (Amaranthus spp.), and sicklepod {Cassia obtusifolia L.
Growers adopting BXN cultivars, particularly BXN 47, report satisfaction with both the weed management technology, except where high populations of sicklepod, pigweed, and certain grass species not controlled by bromoxynil are encountered in cotton production (Culpepper and York, 1999), and the performance of the BXN 47 cultivar.
tillage, and rye mulch on
sicklepod (Senna obtusifolia).
Douglas Boyette at ARS' Southern Weed Science Research Unit, Stoneville, Mississippi, recently discovered that the
sicklepod fungus Myrothecium verrucaria is also an effective bioherbicide for controlling kudzu.
Root morphology of young soybean,
sicklepod, and Palmer amaranth.
A fungus from the
sicklepod plant, Arabis canadensis, found in the south-eastern United States, effectively controls kudzu.
In addition, two weeds - leafy spurge and
sicklepod - and a plant disease - tomato blight - are potential projects.
Pesta containing other weed-killing fungi was tested against
sicklepod and jimsonweed with promising results.
