和除草剂单剂的理论等效线相比，杀草丹和苄嘧磺隆混用的增效值高达４．３倍，增效作用显著。新禾葆热贮处理的稳定性良好，其有效成分杀草丹的分解率为０，苄嘧磺隆的分解率为７．７％。新禾葆防除稗草［Ｅｃｈｉｎｏｃｈｏｌａｇｒａｓ－ｇａｌｉ（Ｌ．）Ｂｅａｕｖ］和千金子［Ｌｅｐｔｏｃｈｌｏａｃｈｉｎｅｎｓｉｓ（Ｌ．）Ｎｅｓｓ］特效，且对水稻安全。
Compared with the theoretical equivalent line of a single herbicide, the synergistic effect of mixed herbicide Dan and bensulfuron-methyl is as high as 4.3 times, and the synergistic effect is remarkable. The new Hebao heat storage treatment stability is good, the active ingredient herbicide Dan decomposition rate of 0, bensulfuron-methyl decomposition rate was 7.7%. Newgrass controls the special effects of barnyard grass [Echinocholagras-gali (L.) Beauv] and Leptochloachinensis (L.) Ness and is safe for rice.
