PROBLEM TO BE SOLVED: To provide a wide angle nozzle for weeding capable of perfectly spraying without making a worker run around a tree and by only rotating a flat type hood, and carrying out high efficiency work by one direction traveling work, namely facilitating the work and requiring minimal fatigue. SOLUTION: This wide angle nozzle for weeding comprises a nozzle tip section 3 having a nozzle part 3a perforated into the base plate portion 2a of the flat type hood 2 and protruded in the hood and a core axis part 3b protruded to the outside of the hood, and a nozzle base section 6 having an elastic plate portion 6a mounted on the core axis part 3b so as to mutually rotate against the nozzle tip section 3 and positioning downward so as to mutually rotate against the outer surface of the hood base plate portion 2a; also has a recess 5 and a projection 7 in which an elastic plate portion 6a and the hood base plate portion 2a engage on the rotational circumference abutted against these portions; and when the hood 2 is rotated in a condition of attaching the nozzle base section 6 to a nozzle pipe, positions the rotation of the hood 2 by disengaging the recess 5 and the projection 7 due to elastic force of the elastic plate portion 6a.
