Pesticides are used to control various pests and disease carriers, such as mosquitoes, ticks, rats and mice. Pesticides are used in agriculture to control weeds, insect infestation and diseases.
There are many different types of pesticides; each is meant to be effective against specific pests. Some examples include:
Algaecides to kill and/or slowing the growth of algae.
Antimicrobials to control germs and microbes such as bacteria and viruses.
Disinfectants to control germs and microbes such as bacteria and viruses.
Fungicides to control fungal problems like molds, mildew, and rust.
Herbicides to kill or inhibit the growth of unwanted plants, also known as weeds.
Insecticides to control insects.
Insect Growth Regulators to disrupt the growth and reproduction of insects.
Rodenticides to kills rodents like mice, rats, and gophers.
Wood Preservatives to make wood resistant to insects, fungus and other pests.
Vietnam has had varying success over the past decade with its pesticides policy. Some of the most toxic pesticides have been banned from the market. But while many countries have successfully decreased agricultural pesticide use per hectare, this has not (yet) happened in Vietnam.
Due to insufficient pesticide management capacity of the Vietnamese government, pesticide types and quantities registered and distributed on the market have substantially increased in Vietnam over the last 10 years.
A 10-year monitoring programme at farm level showed that pesticide use follows the increasing pesticide availability on the market, and many toxic and illegal pesticides are still being used.
In an agricultural country dominated by millions of small-scale farmers and with limited state capacity for control at farm level, reduction of the use of the most toxic pesticides can best be achieved by more effective pesticide market control through stricter and more effective state regulations and implementation, aimed at eliminating illegal, low quality and counterfeit pesticides from the market. But even then, better state and private extension services, and greater state capacity for control and enforcement remain essential in enabling farmers to make better decisions about pesticide use.
