We would like to highlight the interesting reports in The Ecologist about pesticide use in Japan. Phil Carter, a freelance environmental journalist, explores how broad-spectrum pesticides used mainly at rice paddy fields are harming insects and the environment:
Chemical companies are taking advantage of Japan’s weak laws on pesticide use by selling a wide variety of broad-spectrum pesticides for use in rice farming, including neonicotinoids banned in other countries.
But other pesticide types with similarly devastating effects on aquatic ecosystems continue to be sold and promoted, such as Trebon, a synthetic pyrethroid sold by Mitsui Chemicals, and Prince, containing fipronil, a phenylpyrazole sold by BASF.
Simultaneously, a worldwide insect extinction event is ongoing in which broad-spectrum insecticides are implicated as a leading cause.
Japanese rice fields are losing aquatic insects such as iconic autumn darter dragonflies that use the flooded fields in the nymph part of their lifecycle. The resulting pollution of rivers and lakes has also led to the collapse of the fishery in Lake Shinji in Shimane Prefecture, which scientists have connected to neonicotinoid use in surrounding rice fields.
The process of removing dangerous pesticides from use is an arduous one, with companies like Bayer fighting bitterly to continue sales of each product both in court and with campaigns to discredit any critical scientific studies. In recent years, this scorched-earth approach has led to environmental groups focusing their energies on neonicotinoids, eventually achieving bans on some products in the European Union.
