Special pre-emergence herbicide for isatis tinctoria

Abstract

The invention provides a special pre-emergence herbicide for isatis tinctoria. The special pre-emergence herbicide is prepared from acetochlor emulsifiable oil and a synergist No. 3; in the components, 1 part of acetochlor emulsifiable oil and 1 part of synergist No. 3 are uniformly compounded according to the proportion of 1 to 1 to prepare a finished product so as to obtain the special pre-emergence herbicide for the isatis tinctoria. The acetochlor emulsifiable oil is the one with the content of 50 percent. The special pre-emergence herbicide has the advantages that the design of the components is safe and reasonable, a formula is scientific and rigorous, the using is convenient and quick, and weeding is effectively and completely carried out. 1 part of acetochlor emulsifiable oil and 1part of synergist No. 3 are uniformly compounded according to the proportion of 1 to 1 to prepare the finished product, so that the problems of difficulty in pre-emergence weeding on the isatis tinctoria, high cost, a single weeding way, and high labor intensity and great time consumption can be effectively solved.

Description

technical field [0001] The invention relates to a special pre-emergence herbicide for Radix isatidis in the technical field of pesticides, which can comprehensively solve the problem of difficult pre-emergence weeding of Radix isatidis. Background technique [0002] Isatidis planting is a labor-intensive industry, especially weeding in the isatidis 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 isatidis, resulting in a significant reduction in the production of isatidis. Most of the existing pre-emergence herbicides are aimed at field crops such as wheat, corn, soybean, cotton, rice, etc., and they are used in a single way. The pre-emergence herbicides used on Radix isatis have just started in my country, and most of them are from field crop herbicides. Transformed, the species is relatively single, and the weeding area is narrow....

[0002] Isatidis planting is a labor-intensive industry, especially the weeding of Isatidis root fields, 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 effect on the growth of Isatidis root, resulting in a significant reduction in the production of Isatidis root

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