Embodiment 1

[0024] Example 1: 80% cyhalofop-terbuthine aqueous emulsion (1:10)

[0025] In the herbicidal composition containing cyhalofop-ethyl and terbuthyzine, each component is: 7.27% of cyhalofop-methyl, 72.73% of terbuthyrin, 0.02% of brassinolide, 5% of S-100A, and Nongru 600 5%, propylene glycol 1%, and deionized water to make up the balance.

[0026] The process steps are as follows: after mixing the original drug, auxiliary agent and filler according to the weight ratio, pulverize and mix evenly through a homogeneous mixer and a colloid mill, and the finished product is obtained after passing the test.

Embodiment 2

[0027] Example 2: 50% cyhalofop-terbuthine aqueous emulsion (1:9)

[0028] In the herbicidal composition containing cyhalofop-ethyl and terbuthyrine, each component is: 5% cyhalofop-methyl, 45% terbuthyrine, 0.6% dichloroallylamine, AEO 10, 6% sodium alginate, urea 4%, deionized water to make up the balance.

[0029] The process steps are as follows: after mixing the original drug, auxiliary agent and filler according to the weight ratio, pulverize and mix evenly through a homogeneous mixer and a colloid mill, and the finished product is obtained after passing the test.

Embodiment 3

[0030] Example 3: 30% cyhalofop-terbuthine aqueous emulsion (1:8)

[0031] In the herbicidal composition containing cyhalofop-methyl and terbuthyzine, each component is: 3.33% of cyhalofop-methyl, 26.67% of terbutyzine, 1% of antidote T1%, 5% of N,N-dimethylformamide, Sodium alginate 5%, urea 3%, deionized water make up the balance.

[0032] The process steps are as follows: after mixing the original drug, auxiliary agent and filler according to the weight ratio, pulverize and mix evenly through a homogeneous mixer and a colloid mill, and the finished product is obtained after passing the test.

Abstract

The invention relates to a weeding composition, and relates to the technical field of pesticides; the weeding composition comprises cyhalofop-butyl and terbuthylazine, the weight part ratio of cyhalofop-butyl to terbuthylazine is (1-10):(1-20), the weight ratio of cyhalofop-butyl to terbuthylazine is (1-2):(5-10), cyhalofop-butyl and terbuthylazine account for 5%-95% of the total weight of the composition. The cyhalofop-butyl and the terbuthylazine account for 30%-80% of the total weight of the composition, and the protective agent is at least one of brassinolide, isoxadifen-ethyl, cyclopropanesulfonamide, an antidote T, dichloropropenamide and pyraclostrobin. A variety of weeds in the field can be controlled by one-time pesticide use, and obvious synergistic effect on common weeds in a grain field is shown. The weeding composition has a rapid and effective prevention and control effect on common annual gramineous weeds and broadleaf weeds in a millet field, is wide in weed control spectrum, improves the content of amino acid and fat in millet, and achieves a yield increasing effect and improvement of nutritional quality.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition for millet resistant to acetyl-CoA carboxylase inhibitor herbicides and an application thereof. Background technique [0002] Millet has a long history of planting in my country. It is drought-resistant, barren-resistant, and nutritious. It is an important food crop. However, millet is highly sensitive to herbicides and has low competitiveness compared with weeds in the early growth period. , seriously restricted the healthy development of the millet industry. In order to effectively improve production efficiency and market competitiveness, researchers have bred millet varieties resistant to acetyl-CoA carboxylase inhibitor herbicides, such as "Jigu 39", which broadened the The scope of application of herbicides, this kind of millet varieties are popular in production, and the planting area continues to expand. [0003] At present, the herbicides widely...
