Managing problem weeds of irrigated cotton

Abstract

Additional research work has been undertaken to answer a range of questions raised concerning various aspects of WEEDpak. Included are:

1. Provide extension and technical support for WEEDpak. Promote WEEDpak at grower meetings, field days etc 2. Complete study of nutgrass control in commercial cotton 3. Commence herbicide susceptibility studies for dwarf amaranth, David's spurge and red pigweed 4. Commence germination, growth and seedbank studies on dwarf amaranth, David's spurge and redpigweed 5. Examine temperature and photoperiod effects on peachvine and bell vine and initiate seed dormancy experiment 6. Commence field evaluation of herbicides for dwarf amaranth, David's spurge and red pigweed management in permanent beds with retained stubble 7. Monitor weed density and diversity in commercial cotton
