Sometimes negative cross resistance occurs, where resistance to one chemical class of fungicides leads to an increase in sensitivity to a different chemical class of fungicides. Beta-adrenergic blocking agents work by blocking the beta-receptors, thereby preventing epinephrine and norepinephrine from binding to these beta receptors. No single site mode of action should be used in consecutive applications. However, too much increase may result in loss of specificity between the weed and the crop from the action of herbicides.
