Adjuvant Screening for Nicosulfuron·Mesotrione·Atrazine in Maize Fields
摘要
Abstract
To evaluate the optimal adjuvant for the low-dose application of nicosulfuron·mesotrione·atrazine,this study investig ated the effects of four adjuvants(Saileken,Haoqian Beili,Huanong Feiwen,Lvhong Spray Adjuvant)mixed with nicosulfuron·mesotrione·atrazine on the weed control efficacy.The results showed that at 15 d and 30 d af-ter application,the total weed plant control efficacy of the treatment with 30%nicosulfuron·mesotrione·atrazine oil-based suspension concentrate(OD)405 g a.i./hm²(P＜0.05)supplemented with Saileken was higher than those of other treatments,which were 83.54%and 87.26%,respectively.Its efficacy was also significantly higher than that of the 30%nicosulfuron·mesotrione·atrazine OD treatment at the same dosage without adjuvant addition,with an increase of 6.42%and 8.09%correspondingly.At 45 d after herbicide application,the treatment with 30%nicosulfuron·mesotrione·atra-zine OD at 405 g a.i./hm2 added with Saileken achieved the highest total weed plant control efficacy and total weed fresh weight control efficacy,which were 92.07%and 92.32%respectively.All the tested adjuvants exhibited a syner-gistic effect on 30%nicosulfuron·mesotrione·atrazine OD and had no adverse effects on the growth and development of maize.Meanwhile,compared with the water control treatment,all the herbicide-adjuvant combination treatments in-creased the maize yield,with the yield increase rate ranging from 14.97%to 21.76%.The input investment was posi-tively correlated with the output benefits in all treatments.Among them,the treatment with 30%nicosulfuron·me-sotrione·atrazine OD added with Saileken obtained the highest yield and input-output ratio,increasing the yield by 3 473.46 kg/hm2 compared with the blank control treatment,with a yield increase rate of 21.76%and an input-output ratio of 1.00∶29.46.Based on the above comprehensive results,Saileken,one of the tested adjuvants,has an obvious synergistic and yield-increasing effect on nicosulfuron·mesotrione·atrazine.关键词
