SAO PAULO, April 29 (Reuters) - Brazil's Mato Grosso

farmers lobby Aprosoja-MT has filed a lawsuit against global

grain companies over Brazil's so-called "soy moratorium," a

voluntary agreement by traders which bans the purchase of

soybeans from areas of the Amazon deforested after 2008.

The defendants in the suit include the Brazilian units of

ADM, Bunge, Cargill, Louis Dreyfus Company and

COFCO, according to a copy of Aprosoja's complaint filed with

the court and seen by Reuters on Tuesday.

Lobbies for grain exporters, such as Abiove and Anc, are

included as defendants in the proceedings.
