Soybean growers have adopted herbicide tolerant varieties at a rapid rate. While some potential cost savings may have driven adoption, the primary reason growers are switching to new programs is the simplicity and flexibility of a weed control program that relies on one herbicide to control a broad spectrum of weeds without crop injury or crop rotation restrictions. Roundup Ready weed control p...

Typically, low-pressure sprayers are used to uniformly apply pre- and post-emergent herbicides to control weeds in crop rows. An innovative machine for weed control in inter-row and intra-row areas, with a unique combination of inter-row cultivation tooling and intra-row band spraying for six rows and an electro-hydraulic side-shift frame controlled by a GPS system, was developed and evaluated....

In southern pine seedbeds, weed control relies on the use of diphenylether herbicides (oxyfluorfen, lactofen) and selective grass herbicides (sethoxydim and fluzifop-p-butyl). A number of nurseries use a polymer to stabilize the soil after sowing. This helps keep the herbicide barrier intact and extends the preemergence activity. Weekly postemergence applications of low rates are common and hav...

Integrated weed management (IWM) advocates the use of a combination of preventive, cultural, mechanical, and chemical tools to keep weed pressure below threshold levels that reduce yields and profits. Herbicide tolerant crops (HTCs) represent a relatively new weed control technology that can be used in an integrated weed management program. These crops, which enhance weed control options and gr...
