What pesticides do farmers use?
Farmers mix together a variety of pesticides in their agitator drums. These can be categorized into three main groups: herbicides, fungicides, and insecticides . Commonly used insecticides are organic phosphates (OPP) or the controversial neonicotinoids. They keep harmful insects such as aphids at bay in the field, and voracious bugs like the granary weevil off the harvest in storehouses. Most insecticides attack the nervous system of the intended victims. OPPs, for example, inhibit the acetylcholinesterase enzyme and can cause convulsions.

Why are pesticides used in agriculture?
The biggest reason why using pesticides seems worth it to local farmers is because they are a cost-effective way to do more business if their produce is prone to pests. The reality is, that by “playing it safe” and avoiding the use of pesticides, the financial loss that professional growers will incur due to the loss of produce is far greater than the expenses required to purchase pesticides and prevent that from happening in the first place. On top of that, by actively and continuously making your crops “disease-proof”, the chance of the produce being infected in the future drops significantly.
