Problems solved by technology

However, because Bupleurum is a traditional Chinese medicinal material, herbicides in Bupleurum field are also limited by the safety of crops; moreover, excessive herbicide dosage or uneven application may also easily cause residual toxicity to current crops or subsequent crops. These factors limit the application of herbicides in Bupleurum field, resulting in fewer types of herbicides for Bupleurum field and limited herbicidal spectrum. Therefore, there is an urgent need for new herbicides for Bupleurum field

Embodiment 1

[0054] Example 1 Preparation of Bupleurum herbicidal composition emulsifiable concentrate

[0055] Take 5% of high-efficiency haloxyfop-methyl, 20% of promethazine, 5% of calcium dodecylbenzenesulfonate, 3% of alkylphenol polyoxyethylene ether, add mineral oil to make up 100%, and prepare it according to the conventional preparation method The emulsifiable concentrate is the emulsifiable concentrate of the Bupleurum field herbicidal composition with a mass percentage of 25%.

Embodiment 2

[0056] Example 2 Preparation of Bupleurum herbicidal composition emulsifiable concentrate

[0057] Take high-efficiency haloxyfop-methyl 1%, promethazine 9%, calcium dodecylbenzenesulfonate 10%, alkylphenol polyoxyethylene ether 3%, add castor oil to make up 100%, and prepare it according to the conventional preparation method The emulsifiable concentrate refers to the emulsifiable concentrate of the Bupleurum field herbicidal composition with a mass percentage of 10%.

Embodiment 3

[0058] Example 3 Preparation of Bupleurum herbicidal composition emulsifiable concentrate

[0059] Take high-efficiency haloxyfop-methyl 1%, promethonin 24%, calcium dodecylbenzenesulfonate 5%, alkylphenol polyoxyethylene ether 3%, add machine oil to make up 100%, and prepare emulsifiable concentrate according to the conventional preparation method, That is to say, the emulsifiable concentrate of the Bupleurum field herbicidal composition is 25% by mass percentage.

Abstract

The invention belongs to the technical field of agricultural pharmacology and discloses a Bupleurum falcatum field weed control composition and an agricultural chemical preparation thereof. The Bupleurum falcatum field weed control composition is prepared from haloxyfop-R-methyl and prometryn in a mass ratio of 1:24-29:1. The haloxyfop-R-methyl and prometryn are compounded to achieve the synergism effect and can be used for post-emergence weed control of the Bupleurum falcatum field, and the Bupleurum falcatum field weed control composition has wide weed control spectrum, has good removal effect on the weeds in the Bupleurum falcatum field, has long persistent effect, is safe to Bupleurum falcatum crops, can be used for preparing weed control composition pesticides and is particularly suitable for weed control of the Bupleurum falcatum field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a Bupleurum field herbicide composition and a pharmaceutical preparation thereof. Background technique [0002] Bupleurum, also known as Dixun, Shancai, Mushroom Grass, and Firewood; the roots of the plant are dug in spring and autumn, the stems and soil are removed, and the medicinal Bupleurum is obtained after drying. The root of Bupleuri, bitter in nature and slightly cold, returns to the liver and gallbladder meridian; it has the effects of reconciling the exterior and interior, soothing the liver, and promoting yang; it can be used for colds and fever, alternating cold and heat, malaria, liver depression and qi stagnation, and pain in the chest and ribs , prolapse of the anus, uterine prolapse, prevention and treatment of irregular menstruation. Studies have found that the chemical components of Bupleurum include saikosaponins (saikosaponins a, b, c, d four),...
