JOINT DEVELOPMENT BY OTSUKA CHEMICAL AND MITSUBISHI CHEMICAL TO PROVIDE HIGHER YIELDS FOR JAPAN'S FARMERS

The joint development of a new pesticide that could give a substantial boost to Japan's agricultural production -- specifically fruit and vegetable crops -- was announced today by Otsuka Chemical Co., Ltd. of Osaka City (President: Yujiro Otsuka) and Mitsubishi Chemical Corporation (head office: Chiyoda-ku, Tokyo; President: Kanji Shono).

The pesticide, HachihachiEC (common name: tolfenpyrad) was officially registered April 24 as an agricultural chemical. It contains 15% of tolfenpyrad, a compound invented by Mitsubishi Chemical, which has demonstrated superior protective effects against the diamondback moth, common cabbage moth, aphids and other insects that typically attack cabbage, Chinese cabbage and cucumbers.

In addition, it has proven effective in protecting a wide range of fruit and other crops as both an insecticide and as a feeding inhibitor. Because of the broad extent and diversity of its effectiveness, it is considered likely to prove a major benefit to Japan's agricultural sector, increasing yields with less labor.

Mitsubishi Chemical will manufacture and supply the chemical to Otsuka Chemical, which will produce and market Hachihachi in Japan. Arrangements for future registration and marketing the pesticide in other countries are under consideration. Retail sales are currently projected to reach Yen 4 billion a year.

Specific features include:

1. Wide spectrum:
HachihachiEC has been proven effective in protecting against many serious harmful insects simultaneously. In Japan's field of agricultural production, where a variety of harmful insects are prevalent, this will not only increase yields but also prove labor-saving.
2. Effect of antifeeding action:
Depending on the specific insects, it has been shown to inhibit insect feeding, thereby reducing damage to agricultural produce.
3. Insect population control:
It restrains the increase of populations of harmful insects by inhibiting insect egg-laying and reducing egg survival.
4. Effect on harmful insects that resist existing insecticides:
HachihachiEC is effective on destructive insects such as the diamondback moth, aphids and thrips that have developed resistance to existing insecticides such as organophosphates and synthetic pyrethroids.
