摘要： PROBLEM TO BE SOLVED: To provide a method for exterminating a perennial weed by which the perennial weed is effectively terminated while saving labor.
SOLUTION: This method for exterminating the perennial weed comprises the following steps (1)-(4): (1) a chemical-treating step for cutting aboveground parts of the perennial weeds at the initial time of sprouting of the perennial weeds or the growing period of the perennial weeds, and treating the surface of the soil with dazomet or treating the soil by mixing with the dazomet on the day of the cutting or within 14 days after the cutting; (2) an irrigating step for irrigating the ground at 1-50 mm just after the chemical-treating step; (3) a covering step for covering the surface of the soil with a covering material just after the irrigation; and (4) a gas-removing step for removing the covering material at 1-60 days after the covering to remove the gas from the soil before transplanting a crop.

摘要： PROBLEM TO BE SOLVED: To provide a chemical applying apparatus for weeding by a simple and economical technique. SOLUTION: A discharge member 25 extended from a chemical source 21 presses a rotating member 26 to the side surface SA of a bush clearing blade 51 by a proper force and the rotating member 26 is rotated with the rotation of the bush clearing blade 51 when a shake member 25a receives energizing force rotating in the clockwise direction by a spring 81. As a result, a suitable amount of the chemical CS led from the chemical source 21 to a pipe 23 is oozed out from a roller main body 73 to a side cover 26a according to the rotation position of the rotating member 26, namely, the roller main body 73. Consequently, since the chemical CS such as herbicide is applied to the bush clearing blade 51 in weed clearing by a portable type bush cutter 100, not only weeds are removed by a bush clearing operation but also weed growth is efficiently suppressed by the herbicide attached to weeds remaining after bush clearing.
