<p><P>PROBLEM TO BE SOLVED: To provide a sprayed agrochemical detection method using photoanalysis techniques for determination for determining the state of an agrochemical sprayed over farm produce, after spraying. <P>SOLUTION: Liquids (solvents 19, 19, ...) are placed in collecting containers 1, 1, ... with their upper surfaces being left open. The plurality of collecting containers 1, 1, ... are located at a place in a farm field. At spraying the agrochemical, the sprayed agrochemical is acquired (gathered) in the solvents 19, 19, ... in the collecting containers 1, 1, .... Data acquired by spectrally analyzing the solvents 19, 19, ... by means of infrared light and data previously taken by spectrally analyzing liquids by means of infrared light, the liquids made by dissolving an agrochemical of known concentration in the solvents 19, 19, ... are input into a computer 18 for comparative operation, thereby measuring the amount of sprayed agrochemical. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
