PROBLEM TO BE SOLVED: To provide a watering tube having light resistance and an effect of keeping insects off, and making dirt obscure. SOLUTION: The watering tube 1 is composed of a tube body 3 which is set with water spray small holes 2 for water spraying at prescribed intervals in the length direction, and formed of a soft synthetic resin, and a colored layer 4 which is laminated on the surface of the tube body 3 and colored in silver. As a result of this, the watering tube effectively keeps insects off, and is prevented from being chewed by insects such as cricket. Furthermore, the watering tube 1 has light resistance equal to that of a conventional black tube by coloring the surface thereof silver, and also makes dirt obscure compared to a white tube, so the beautiful spectacle of a farmland or an agricultural greenhouse is not destroyed.
