To provide a spraying controller of a pest control machine, by which the abnormality of various sensors used in the spraying controller can be simply ascertained at a working site.
In this spraying controller of the pest control machine, a control means 10 has a sensor abnormality detection means 11 for detecting the abnormality of each sensor on the basis of the output of the sensors (a pressure sensor 21, a flow rate sensor 22, a vehicle speed sensor 23); and the sensor abnormality detection means 11 specifies a sensor to be detected, compares the detection value of the sensor with a target value in a state operating a spraying device 1 or a travel machine frame so that spraying conditions for detecting with the sensor become set target values, and detects the abnormality of the sensor when the difference between the detection value of the sensor and the target value is not included in a set tolerance.
