There are several known side effects of maneb. One of these is it may cause irritation or inflammation in the skin, eyes, and respiratory tract. Short-term inhalation of large quantities of maneb dust or spray may cause irritation of the mucous membranes, resulting in a scratchy throat, sneezing, cough, and inflammation of the linings of the nose and upper respiratory tract.
