Studies were conducted to find out the justification for levee-burning, customarily executed by farmers for long time, Experiments were carried out in farmers fields with levee-burning early in the season, and some pesticides spraying when necessary from 1995 to 1997. Some data collected are analysed and discussed from several available aspects of surroundings. In relation to some results obtained together with some previous evidences, levee-burning seems to have several adverse effects on levee destruction, partial cause of forest fire, and lowering of spider density in the field during fall, without providing any benefit, while causing no signifant effect on weed flora on levee, insect density in the field, and incidence of the rice-blast. Therefore, concequently, it could be recommend that the levee-burning by farmers should not be continued.
