A large-scale spraying operation was conducted on May 3, 2025.
Approximately 300 liters of herbicide diluted at a 1:100 ratio were used.
The spray nozzle was replaced with a three-nozzle type, which significantly increased
the spraying area per hour.
A 200-liter polyethylene tank is equipped with an engine-powered spray pump.
A 200-liter polyethylene tank is equipped with an engine-powered spray pump.
The pump can reach a pressure of up to 3.5. When the nozzles are closed at high
pressure, the herbicide circulates back into the tank through a bypass hose.
Each batch of diluted herbicide is prepared by mixing 2 liters of concentrate with 200
liters of water.
As the mixture contains a surfactant and tends to foam, it's important to fill the tank
As the mixture contains a surfactant and tends to foam, it's important to fill the tank
with water first, then add the concentrate.
Since the tank’s full line is located near the top, the suction hose and bypass hose must
Since the tank’s full line is located near the top, the suction hose and bypass hose must
be removed during transport, and the lid must be secured tightly.
2025.05.03にかなり大規模な散布を行った。
100倍希釈の除草剤で300Lほど。
噴霧ノズルを3口タイプに交換したので、時間あたり散布面積が一気に増加した。
200Lのポリタンクにエンジン稼働の噴霧ポンプが装備。
ポンプ圧縮は3.5まで可能、高圧縮時に、ノズルを閉じると噴霧ポンプからバイパス
ホースでポリタンクに還流する仕組みになっている。
一回の薬液希釈は水200Lに原液2Lで作成する、界面活性剤が含まれているので泡立ちに
注意が必要であるため、最初に水200Lを用意し、そこに原液を投入する。
ポリタンクの満水線はかなり上にあるため移動時には、吸い込みホースや還流用ホースは
一旦取り外し、しっかり蓋をした状態にする。
