or liters) and the content of the active ingredient (indicated in percentage), precautions in application (application time, which substances and pesticides can not be mixed, poisoning symptoms and first aid methods, safe days between a pesticide application and harvesting, etc.), the name of the pesticide manufacturer, delicate address, **, zip code, production date and shelf life.

After confirmation, the amount of pesticides to be purchased is determined according to the area of crops that you need to control.
