Legal analysis: First, dichlorvos is a toxic pesticide, which should not be stopped at present, but only requires rational use. Second, if the local agricultural commission or the industrial and commercial drug supervision department does not have local requirements, sales are not illegal. Third, agricultural stores should be irresponsible if they have complete licenses and regular purchase channels. Unless it is clearly stated at the time of purchase that it will be used for suicide, and the owner has not stopped it, it should not bear legal responsibility.
