Essay | Please explain the significance of monitoring pesticide residues in green leafy vegetables and how it contributes to sustainable agriculture.
|
Overuse of pesticides can cause toxic chemicals to build up in plants and can cause harm to their natural pollinators or to humans who ate them, therefore it is important to monitor its use in order to ensure that the toxins are within safe levels but is still able to ward off pests |
