ADDITIONAL INDEX WORDS. flaming machine, insect pest, paraquat, southern China, thermal weeding SUMMARY. Widespread herbicide-resistant weeds and severe insect pest infestations pose a challenge to the preplant pest management (PPPM) strategy currently in use in leaf vegetable fields in southern China. The aim of this study was to develop a new weed and insect control method for use before planting leaf vegetables in southern China. Two flaming machines (a tractor mounted and a trolley flaming machine) were designed, and their efficacies for the control of insect and weed pests were evaluated and compared in two field trials. With liquefied petroleum gas (LPG) at 101 kgÁha L1 , flaming machines reduced plant numbers by 86.7% to 98.8% 2 days after treatment (DAT), which was equal to or higher than the reduction after application of paraquat at 900 gÁha L1 . Some weed species, especially awnless barnyard grass (Echinochloa colona) and goosegrass (Eleusine indica), regrew at 7 DAT, resulting in a decrease in control efficacy. Flaming machines also reduced the number of diamondback moth (Plutella xylostella) larvae by 83.0% to 88.2% and the number of adult striped flea beetles (Phyllotreta striolata) by 64.9% to 80.9%. This is the first report on flaming treatment in China to show that this method is a promising alternative to chemical pesticides for PPPM in leaf vegetable fields.

Weed management is a major constraint in organic crop production. The main objectives were design, development and evaluation of a targeted-discrete flame weeder in laboratory and comparing continuous (uniform) flame weeding with targeted flaming of inter-row weeds in an organic maize production field. In the laboratory tests, optimum angle and height of burners, as well as accuracy and precision of the targeted discrete-flamer were evaluated at three levels of ground speed (0.5, 0.7 and 0.9 m s -1 ). In the field experiments, the effects of the same ground speed levels at three maize plant growth stages (4, 6 and 8 leaves denoted by V4, V6 and V8, respectively) on weed eradication as well as on fuel consumption were investigated. The results of the laboratory tests showed that the optimum position of burners were 25 cm above the ground surface and inclined at 30º for achieving acceptable accuracy in application of targeted flaming. In the field trials, uniform (continuous) and targeted (discrete) flaming showed similar results in weed eradication, while fuel consumption of the targeted method was significantly lower than the uniform application. Also, based on the field experiments, weed control calculated three days after flaming (3DAF) was significantly higher than that of one day after flaming (1DAF) and the first flaming was significantly more effective than the second and third flaming. The results of this investigation indicates that targeted-discrete flame weeding by using machine vision technology is a potential alternative to uniform flaming with extra advantages of lower fossil fuel consumption and air pollution.
