摘 要：
选择麦极、骠马、大能、优先、彪虎、爱秀、世玛7种茎叶处理除草剂,开展其防除小麦田大龄硬草试验。结果表明:15%麦极WP 300 g/hm~2、50 g/L大能EC 1 200 mL/hm~2、50 g/L爱秀EC 900 mL/hm~2和30 g/L世玛OF 300 mL/hm~2+助剂900 mL/hm~2在试验条件下可有效防除2—3分蘖期的硬草,药后150 d的株数防效和鲜重防效均大于90%,69 g/L骠马EW 1 500 mL/hm~2对2—3分蘖期的硬草也有较好的防效,药后150 d株数防效接近90%,鲜重防效优于株数防效,70%彪虎WG 60 g/hm~2和7.5%优先WG 150 g/hm~2+助剂450 mL/hm~2处理对2—3分蘖期的硬草防效较差,药后150 d株数防效和鲜重防效均不足41%,不足以有效控制大龄硬草的危害。各供试药剂及剂量对小麦生长安全。

摘 要：
Evaluation test for 7 post-emergence herbicides against Sclerochloa kengiana(Ohwi) Tzvel which at2—3 tillers stage was carried out in wheat field.The results showed that 15%clodinafop-propargel WP 300 g/hm~2,50 g/L clodinafop-propargyl + pinoxaden EC 1 200 mL/hm~2,50 g/L pinoxaden EC 900 mL/hm~2,30 g/L mesosulfuron-methyl OF 300 mL/hm~2 + adjuvant 900 mL/hm~2 could effectively control the Sclerochloa kengiana(Ohwi)Tzvel,investigated at 150 DAA,the population efficacy and fresh weight efficacy of above mentioned herbicides were all above 90%,69 g/L fenoxaprop-p-ethyl EW treated at 1 500 mL/hm~2,the population efficacy were close to 90%,the fresh weight efficacy was better than the population efficacy,7.5%pyroxsulam WG 150 g/hm~2 +adjuvant 450 mL/hm~2 and 70%flucarbazone-Na WG 60 g/hm had worse effect to Sclerochloa kengiana(Ohwi)Tzvel,the population efficacy and fresh weight efficacy were less than 41%that were not enough to control the damage of Sclerochloa kengiana(Ohwi)Tzvel.All the tested herbicides were safe to wheat growth.
