Weed management in corn and soybeans can be an extremely difficult problem to tackle and, if left unmanaged, can cause nearly a 52% corn yield loss and 49% yield loss in soybeans according to research conducted by the Weed Science Society of America and Kansas State University. ...
The crop enemies investigated were: weeds for corn (Zea mays); and for apple orchard (Malus pumila), three insect pests (codling moth (Cydia pomonella), plum curculio (Conotrachelus nenuphar) and apple maggot (Rhagoletis pomonella)) and two diseases (apple scab (Venturia inaequalis) and fire blight (Erwinia amylovora)). ...
Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High populations of this weed can occur in fields of continuous corn. A high population of ...
As corn planting dates were delayed, greater amounts of vetch mulch and lower weed density helped reduce weed biomass. ...
Received for publication October 28, 2008. Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and ...
The objective of this study was to evaluate how an integrated crop–livestock system would influence weed biomass and weed species composition compared with a conventional, continuous corn (Zea mays L.) cropping system. ...
However, as herbicide-tolerance and insecticidal traits are often simultaneously expressed by individual plants, glyphosate [N-(phosphonomethyl) glycine]-resistant (GR) volunteer corn is becoming a widespread problem as a weed in corn-soybean rotational systems. We show that these volunteer corn plants not only have ...
Terbuthylazine (TA) is a herbicide that has been introduced for weed control in corn cultivations as a direct replacement for atrazine. Because incorporation of different organic amendments (OAs) is a common practice in this crop, this study investigated the effects of different OAs, including urban sewage sludge, poultry compost, and corn straw ...
The objective of this study was to determine the contribution of CCs [rye (Secale cereal L.) and hairy vetch (Vicia villosa Roth)] on plant N nutrition and weed suppression to the following sweet corn (Zea mays L.). The CCs were planted in the fall of 2003 and 2005, and sweet corn was planted in spring of 2004 and 2006. ...
Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control ...
We conducted a 9-ha field experiment near Boone, IA, to test the hypothesis that yield, weed suppression, and profit characteristics of low-external-input (LEI) cropping systems can match or exceed those of conventional systems. Over a 4-yr period, we compared a conventionally managed 2-yr rotation system {corn (Zea mays L.)/soybean [Glycine max (L.) Merr.]} with ...
The five FSP cropping systems include a conventional no-till corn–soybean–wheat/soybean rotation (NT), a conventional chisel-till corn–soybean–wheat/soybean rotation (CT), a 2-yr organic corn–soybean rotation (Org2), a 3-yr organic corn–soybean–wheat rotation (Org3), and a 4- to 6-yr organic ...
The objective of this study was to quantify interspecific competition of self-seeded winter cereal cover crops growing concurrently with corn. Total weed density responded more to environment than cover crop treatment, with 12.0 and 2.2 weeds m–2 in 2005 and 2006. Averaged across species, cover crop treatments lowered corn grain ...
