Steaming soil is effective in eliminating invasive alien plants (IAPs) - part I: effect of exposure method. [PDF]

Pest Manag Sci
As regulations on chemical pesticides become more stringent, it is likely that there will be interest in water steam as an alternative approach for soil disinfestation. This study investigated the feasibility of utilizing a soil steaming device for thermal control of selected invasive alien plants and showed a promising mortality rate for their ...

Will the Amaranthus tuberculatus Resistance Mechanism to PPO-Inhibiting Herbicides Evolve in Other Amaranthus Species? [PDF]

International Journal of Agronomy, 2012
Resistance to herbicides that inhibit protoporphyrinogen oxidase (PPO) has been slow to evolve and, to date, is confirmed for only four weed species. Two of these species are members of the genus Amaranthus L. Previous research has demonstrated that PPO-
