摘　　要：盐城市稻茬麦田泽漆发生较 2 0世纪 80年代前大为严重 ,其发生高峰在小麦播种后 15～ 2 0d ,全生育期约 2 0 0d。泽漆发生密度和小麦产量损失及穗数减少均呈直线函数关系 ,其危害临界期在 2月 2 5日～ 3月 2 5日之间。化防试验结果表明 ,冬前应用 2甲 4氯 +使它隆或 2甲The damage of sun euphorbia in wheat field was becoming serious and its occurrence peak was from fifteenth to twentieth day after wheat sowing. The growth period of sun euphorbia was 200 days. The relation between of the growth density of sun euphorbia and wheat yield and panicle decrease was the linear correlation and the period of damage happened was from 25 Feb. to 25 March.
