Special herbicide for pre-emergence of platycodon roots

Abstract

The invention discloses a special herbicide for pre-emergence of platycodon roots, and relates to the technical field of pesticides. The special herbicide consists of acetochlor emulsifiable concentrate and a synergist No. 1, wherein the acetochlor emulsifiable concentrate is acetochlor emulsifiable concentrate with a content 50%, and comprises the following components in parts by weight: 1 part of the acetochlor emulsifiable concentrate and 3 parts of the synergist No. 1, which are evenly compounded into a finished product according to a ratio of 1 to 3 to prepare the special herbicide for pre-emergence of platycodon roots, and a safe, reasonable, convenient and efficient pre-emergence weeding scheme for platycodon root with low toxicity and high efficiency is provided. The special herbicide can effectively prevent and eliminate annual gramineous weeds and various dicotyledonous weeds in platycodon root fields under the condition of ensuring the growth safety of platycodon roots. Thespecial herbicide greatly reduces the labor intensity of platycodon root weeding and improves the success rate of platycodon root production.

Description

technical field [0001] The invention relates to a special pre-emergence herbicide for platycodon grandiflorum in the technical field of pesticides, which can comprehensively solve the problem of difficult pre-emergence weeding of platycodon grandiflorum. Background technique [0002] Platycodon planting is a labor-intensive industry, especially weeding in the platycodon field, which is not only troublesome and laborious, but also inefficient. If you don’t pay attention, it will form a grass shortage, which will have a very adverse effect on the growth of the platycodon, resulting in a substantial reduction in the production of the platycodon. Most of the existing pre-emergence herbicides are aimed at field crops such as wheat, corn, soybeans, cotton, rice, etc., and are used in a single way. The pre-emergence herbicides used on Campanulaceae have just started in my country, and most of them are transformed from field crop herbicides. As a result, the variety is relatively s...

[0002] Platycodon planting is a labor-intensive industry, especially weeding in the platycodon field, which is not only troublesome and laborious, but also inefficient. If you don’t pay attention, it will form grass shortages, which will have an extremely adverse impact on the growth of platycodon, resulting in a substantial reduction in the production of platycodon

Most of the existing pre-emergence herbicides are aimed at field crops such as wheat, corn, soybeans, cotton, rice, etc., and are used in a single way. The pre-emergence herbicides used on Campanulaceae have just started in my country, and most of them are transformed from field crop herbicides. However, the variety is relatively single, and the grass-killing area is narrow
