In any case in which an action for injunction is brought alleging the prior misuse of agricultural chemicals and the court finds that the defendant properly used the agricultural chemicals according to state and federal law and the label instructions and that the plaintiff sustained no damages from the use of such agricultural chemicals, the court may assess against the plaintiff reasonable attorney fees and expenses incurred by the defendant as a result of such action. In addition, the court may assess against the plaintiff additional losses and costs incurred by the defendant upon proof that such losses and costs were the result of an injunction granted as part of such action. Any assessment under this section shall be reduced (but not below zero) by an amount equal to the amount of any bond forfeited to the defendant under article 9 of chapter 60 of the Kansas Statutes Annotated. An assessment under this section shall be collected as costs in the action. This section shall be part of and supplemental to the provisions of article 32 of chapter 2 of the Kansas Statutes Annotated, and acts amendatory of the provisions thereof or supplemental thereto.
