Last Updated: 2024/11/06, Weeds can seriously affect the yield and quality of licorice. It competes with licorice for sunlight, water and nutrients. Some weeds are intermediate hosts of licorice crop diseases and insect pests, helping to spread and spread diseases and insect pests. Especially artificial cultivation of licorice at seedling stage, if weeds are not eliminated in time, a large number of dead seedlings will be caused, even seed destruction. Now chemical herbicides are often used in addition to artificial weeding. Artificial licorice in our county is now promoting the following three chemical herbicides: Acetochlor, Shitianbu and Doucaote. Practice has proved that the use of chemical herbicides is the guarantee.

Weeds can seriously affect the yield and quality of licorice. It competes with licorice for sunlight, water and nutrients. Some weeds are intermediate hosts of licorice crop diseases and insect pests, helping to spread and spread diseases and insect pests. Especially artificial cultivation of licorice at seedling stage, if weeds are not eliminated in time, a large number of dead seedlings will be caused, even seed destruction.

At present, in addition to artificial weeding, chemical herbicides are often used to control weeds. Artificial licorice in our county is now popularizing the following three chemical herbicides: Acetochlor, Shitianbu and Doucaote. Practice has proved that the use of chemical herbicides is an effective measure to ensure the healthy growth of licorice, increase yield, improve quality and save labor. This paper introduces the application methods of the above three commonly used licorice herbicides.

Acetochlor and Shitianbu are both closed agents with similar herbicidal effects. Timely application can restrain the germination of many kinds of weed seeds, the application rate is 200ml per mu (1.5 mu per bottle is suitable), and infiltrate into the water before spraying or watering. The application time was controlled before the weed seeds germinated and unearthed, but had no effect on the unearthed weeds. The limited period is 2MQ for 3 months, and it is recommended to apply it twice a year.

2. Doucaote: the special validity period of legume crops is long, and it is sensitive to non-legume crops. It is not suitable to plant other crops within three years, 500ml per bottle, with an area of 2.5 mu, once a year. To the thrush grass (commonly known as: sesame oil) does not work, immediately after spraying with Quine and Lingshu eyebrow grass.
