Abstract
In order to screen the herbicide types or combinations suitable for controlling annual weeds in Scutellaria baicalensis field,a survey was conducted on the types and quantities of weeds in Scutellaria baicalensis fields.Based on the main weeds,13 representative herbicides for stem and leaf treatment were selected for efficacy testing to determine the weed control effect and dosage.The results showed that 60 g/L nicosulfuron OD 750.0 mL/hm2,12%rimsulfuron OD 120.0,187.5 mL/hm2 and 10.8%quizalofop-p-ethyl EW 450.0,675.0,1 350.0 mL/hm2,108 g/L haloxyfop-p-methyl EC 375.0,450.0,900.0 mL/hm2 were safe for Scutellaria baicalensis,and the fresh weight reduction rate was-17.96%--1.35%.All or most of the Scutellaria baicalensis plants treated with 480 g/L and other herbicides died and the plants were weak and yellow,which were not safe for Scutellaria baicalensis.On the 30th day after treatment,the total plant control effects of 12%rimsulfuron OD 120.00,187.50,240.00,375.00 mL/hm2 on annual broad-leaved weeds in Scutellaria baicalensis field were 84.08%-90.55%,and the fresh weight control effect was 89.30%-95.38%.The total plant control effect on annual Gramineae weeds was 54.90%-73.20%,and the fresh weight control effect was 60.16%-78.52%.The plant control effects of 10.8%quizalofop-p-ethyl EW 450.00,675.00 mL/hm2 were 90.20%-95.42%,and the fresh weight control effect was 93.19%-97.00%.The plant control effects of 108 g/L haloxyfop-p-methyl EC 375.00,450.00 mL/hm2 on annual grass weeds in Scutellaria baicalensis field were 95.42%-99.35%,and the fresh weight control effects were 97.23%-99.54%.It is safe to use 12%rimsulfuron OD 120.0-187.5 mL/hm2 to control annual weeds such as Amaranthus retroflexus,Portulaca oleracea and Eleusine indica.When the Gramineae weed population is large,10.8%quizalofop-p-ethyl EW 450-675 mL/hm2 or 108 g/L haloxyfop-p-methyl EC 375-450 mL/hm2 can be added to increase the control effect on Gramineae weeds.关键词
