The invention belongs to the technical field of agricultural equipment and particularly relates to disease and insect pest control equipment for agricultural and forest crops. The equipment comprisesa vehicle body, a water passage pipe and a sprinkling assembly. The equipment further comprises a driving unit, a swinging unit, an air cylinder I, a fixing block I, a fixing block II, a water tank and a hose. The driving unit is used for moving the vehicle body; and the swinging unit is used for enabling the sprinkling assembly to sprinkle uniformly. The driving unit and the swinging unit are matched with each other, so that on one hand, an insecticide solution is sprinkled to the agricultural and forest crops according to actual conditions, the sprinkling is uniform, the damage to the agricultural and forest crops caused by plant diseases and insect pests is avoided, and thus, the effect of disease and insect pest control on agriculture and forestry is improved; and on the other hand, apower source of the equipment is utilized, so that the utilization ratio of resources is increased, meanwhile, external power equipment is reduced, and thus, the manufacturing cost of the equipment isreduced.
