PURPOSE:To spread thoroughly an agricultural chemical to the rear of the leaves of crops, etc. by forming a nozzle body of ceramics working and forming the same in such a way that the chemical can be sprayed in a fan shape toward right and left directions. CONSTITUTION:A nozzle body 2 is formed of ceramics working and is punched with two injection ports 3, 4 to permit spraying in a 45 deg. fan shape to the right and left. A groove 5 having a semicircular section connecting the ports 3, 4 is provided on the inside surface and further a nozzle protective cap is fitted in the outside wall part. If an agricultural chemical having the pressure higher than the pressure in a conduit is sprayed in the stage of use, the agricultural chemical is sprayed in a fan shape in a 45 deg. direction from the right and left ports 3, 4 and when the chemical advances in, for example, an arrow 12A direction, the spray in the left direction is effected from the lower to upper part of crops and the spray in the right direction is effected from the upper to lower part of the crops, whereby the chemical is uniformly sprayed. |
