Embodiment 1

[0039] The present embodiment provides a compound herbicide for controlling Ligularia spp., comprising the following components: 40 parts of 2,4-D butyl ester; 50 parts of tribenuron-methyl; 40 parts of urea; 10 parts of sodium dodecylbenzenesulfonate 5 parts; 5 parts of alkylphenol polyoxyethylene ether; 8 parts of ethoxy-modified trisiloxane.

[0040] The preparation method of described herbicide is:

[0041] Slowly add 2,4-D butyl ester into the stirring tank, dilute with 5 liters of tap water, stir at 50 rpm for 5 minutes, and mix the diluted solution evenly; then, weigh the corresponding mass of benzenesulfonate Put the powder into the mixing tank and stir for 10 minutes at a speed of 80 rpm; then, add sodium dodecylsulfonate, alkylphenol polyoxyethylene ether and ethoxylated trisiloxane in sequence, and control the speed at Stir at 120 rpm for 30 minutes to achieve full mixing of the agents in the mixing tank to obtain a mixed solution A, and separate the urea and the m...

Embodiment 2

[0043] This example provides a compound herbicide for controlling Ligularia syringae, comprising the following components: 90 parts of 2,4-D butyl ester; 10 parts of tribenuron-methyl; 70 parts of urea; 1 part of sodium dodecylbenzenesulfonate 15 parts; 15 parts of alkylphenol polyoxyethylene ether; 4 parts of ethoxy-modified trisiloxane.

[0044] The preparation method of described herbicide is:

[0045] Slowly add 2,4-D butyl ester into the stirring tank, dilute with 9 liters of tap water, stir at 50 rpm for 5 minutes, and mix the diluted solution evenly; then, weigh the corresponding mass of benzenesulfonate Put the powder into the mixing tank and stir for 10 minutes at a speed of 80 rpm; then, add sodium dodecylsulfonate, alkylphenol polyoxyethylene ether and ethoxylated trisiloxane in sequence, and control the speed at Stir at 120 rpm for 30 minutes to achieve full mixing of the agents in the mixing tank to obtain a mixed solution A, and separate the urea and the mixed s...

Embodiment 3

[0047] The present example provides a compound herbicide for controlling Ligularia spp., comprising the following components: 60 parts of 2,4-D butyl ester; 30 parts of tribenuron-methyl; 55 parts of urea; 6 parts of sodium dodecylbenzenesulfonate 10 parts; 10 parts of alkylphenol polyoxyethylene ether; 6 parts of ethoxy-modified trisiloxane.

[0048] The preparation method of described herbicide is:

[0049] Slowly add 2,4-D butyl ester into the stirring tank, dilute with 6 liters of tap water, stir at 50 rpm for 5 minutes, and mix the diluted solution evenly; then, weigh the corresponding mass of benzenesulfonate Put the powder into the mixing tank and stir for 10 minutes at a speed of 80 rpm; then, add sodium dodecylsulfonate, alkylphenol polyoxyethylene ether and ethoxylated trisiloxane in sequence, and control the speed at Stir at 120 rpm for 30 minutes to achieve full mixing of the agents in the mixing tank to obtain a mixed solution A, and separate the urea and the mix...

Abstract

Belonging to the technical field of herbicides, the invention in particular relates to a novel compound herbicide for control of Ligularia virgaurea, a preparation method and a use method thereof. Theherbicide comprises the following components by weight: 40-90 parts of 2, 4-D butyl ester; 10-50 parts of tribenuron-methly; 40-70 parts of urea; 1-10 parts of an anionic surfactant; 5-15 parts of anemulsifier; and 4-8 parts of polytrisiloxane. The herbicide provided by the invention is suitable for the natural grassland where Ligularia virgaurea occurs in a large area, 15 days after spraying, Ligularia virgaurea begins to die, and a quick effect can be achieved. In general, no drug residue can be detected in plants in about 10 days, and no drug residue can be detected in soil in about 7 days, the compound herbicide degrades quickly and has small toxicity, and obviously improves the pasture quality and yield. At the same time, the cost can be reduced by 77.8%, thus greatly saving herdsmen's expenditure on prevention and control.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a novel compound herbicide for preventing and controlling Ligularia spp. and its preparation method and application method. Background technique [0002] Ligularia virgaurea (Ligularia virgaurea) is a poisonous perennial plant of the genus Ligularia in the Asteraceae family. It is widely distributed in the alpine grasslands of the Qinghai-Tibet Plateau and Nepal. Because the branches and leaves of Ligularia chinensis contain white toxic emulsion, livestock will be poisoned and die after eating. At the same time, Lignus chinensis has both seed reproduction and rhizome reproduction capabilities, and its coverage in natural grasslands has continued to increase, seriously reducing the yield of edible pastures and causing major losses to the development of local animal husbandry. [0003] At present, the control methods of grassland poisonous weeds mainly include manua...
