What are the advantages and disadvantages of agricultural chemicals?

Question

pls i want the current information

Answer 1

Advantages are enhanced, better quality yields.

Disadvantages are potential misuse, over- or under- application, and chasing after growth rates at the expense of public and animal health.

Answer 2

Chemicals allow for high yields with limited labor especially with huge tracts of monoculture. They allow the farmer to shortcut nature to some advantage. The disadvantages though are that no matter what the claims are by the manufacturers, those chemicals always reside in the soil in whole or in part and adversely affect the whole of the environment. Statistically 90% of pesticides/ chemicals are what removes those couple little blemishes on a crop, like the occational little spot on your apple. Residue whether it is surface or incorporated in the actual crop is measured and compared with the LD50, the levels of a chemical that will kill 50% of the animal that consumes it, and the small PPM or PPB are considered to be within safe levels. These materials though are still there and frequently are cumulative poisons, really terrible if you work with these materials or have them everpresent in your environment. Even after they pass threw you they end up in the waste water to slowly be spread around. Some countries still use DDT. Many agro chemicals are formed around heavy metals and certain classes of insecticides are from the chemical warefare research and that wonderful legacy of modern human society. Little research is done except what needs to be done to field a product and make as much money as possible before followup studies prove those materials to be problematic. Like DDT. Like Paraquat. Like so many others. Guess yet if I favor chemicals? Fertilizer, as I said, shortcuts nature and makes our food source dependant on chemical companies and the petrolium industry. It all ends up back in our water to find it's way to the oceans where it disrupts the aquatic ecology and further reduces fish populations and contaminates the rest. I can't even allow my children to have more than one tuna sandwich weekly, and that only because they enjoy it so much. These above mentioned industries, and others to include governments and their balancing act of imports and exports, are the leading characters in the high price of foods even though all the users of those materials claim we would all starve without them. They have been depending on them for so long they now believe it to be true. Too many people want to make their money and bank it away while they can and environment be damned. The "Five Nations" believe that one must do a thing with consideration of seven generations and that is something all would do well to live by.
