Pesticides are chemicals or biological agents used for repelling, preventing and killing pests that can damage plants. Pests can be insects, weeds, birds, mammals, nematodes or microbes. Although pesticides are beneficial for plants, their inherent toxic nature renders them harmful for animals and human beings. If disposed inappropriately, pesticide poisoning can be fatal. Hence, it becomes critically important to dispose them off safely. Pesticides must be disposed when unused pesticide remains in the original container.
It is advisable to dispose the remaining pesticide after use. Usually, after application, the pesticide containers may contain some amount of the substance or trace chemicals left over. Find out if the label on the container has any specifications regarding the disposal methods. Most pesticides have labels on them specifying disposal methods and procedures. If not, you can check with the local waste management authority for the same.
Pesticides in the Original Container
Vefore you decide to dispose the pesticides, check whether any of your friends of neighbors need it. Otherwise, the best way to dispose unused pesticides in containers is to read and follow the disposal instructions mentioned on its label. Do not burn or bury pesticide bags or containers unless it is specifically mentioned.
