Special preemergence herbicide for rhizoma bletillae

Abstract

The invention provides a special preemergence herbicide for rhizoma bletillae. The finished product of the special preemergence herbicide for the rhizoma bletillae is prepared by uniformly compounding5 parts of acetochlor emulsifiable concentrate and 5 parts of synergist 5 according to the proportion of 1 to 1. The content of the acetochlor emulsifiable concentrate is 50 percent. The special preemergence herbicide for the rhizoma bletillae, disclosed by the invention, has the advantages of safe and reasonable component design, scientific and rigorous formula, convenience and quickness in useand efficient and thorough weeding. By uniformly compounding 5 parts of the acetochlor emulsifiable concentrate and 5 parts of the synergist 5 to obtain the finished product according to the proportion of 1 to 1, the problems of difficulty in preemergence weeding of the rhizoma bletillae, high cost, single weeding and labor and time waste can be effectively solved.

Description

technical field [0001] The invention relates to a special pre-emergence herbicide for bletilla striata in the technical field of pesticides, which can comprehensively solve the problem of difficult pre-emergence weeding of bletilla striata. Background technique [0002] The cultivation of bletilla striata is a labor-intensive industry, especially the weeding of bletilla striata, which is not only troublesome and laborious, but also inefficient. If you don't pay attention, it will cause grass shortage, which will have an extremely adverse impact on the growth of bletilla striata, resulting in a significant reduction in bletilla striata production. 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 Bletilla striata have just started in my country, and most of them are from field crop herbicides. Transformed, the species is relatively si...

Problems solved by technology

[0002] The cultivation of bletilla striata is a labor-intensive industry, especially the weeding of bletilla striata, which is not only troublesome and laborious, but also inefficient. If you don't pay attention, it will cause grass shortage, which will have an extremely adverse impact on the growth of bletilla striata, resulting in a substantial reduction in the production of bletilla striata

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 Bletilla striata 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
