Problems solved by technology

After careful examination of the known extermination methods, it is found that the existing technology has the following problems: 1. The herbicides currently used in farmland are directly used on grasslands, and general herbicides have no special effect when used for poisonous weed control
When the concentration of the agent is small, the killing effect is poor, and when the concentration of the agent is high, it will cause phytotoxicity to the fine pasture in the herb
2. In the existing compound wolfbane preparations, the proportion of the drug 2,4-D butyl ester used in large quantities in its proportioning ratio is relatively high, and most of the drugs used in other patents are unstable and easy to decompose in acid and alkali environments. And it is easy to cause problems such as environmental pollution

Embodiment 1

[0209] The test of eradicating chamaejasma was carried out on the grassland of Haiyan County, Qinghai Province. The spraying area was 10 hectares, and the specific drug ratio was as follows:

[0210] J1: 2,4-D butyl ester 34.2%;

[0211] K1: Gibberellic Acid A 3 0.1%;

[0212] L1: Ethylene glycol 3.0%;

[0213] M1: Lubricant I (SAE: 15W-60, API: CD): 62.7%;

[0214] Spraying in the blooming stage of chamaema chamaejasma, the equipment is a backpack motorized sprayer. The medicine is sprayed directly without adding water, and the application rate is 1050ml / ha. When spraying the medicine, the knapsack sprayer walks 80 meters per minute, the height of the nozzle from the ground is kept at 1 meter, and the spray width of the nozzle is 10 meters. Three hours after spraying, the leaves of St. chamaejasma wilted and died 50 days later. In the second year, the mortality rate of the marked chamaejasma plants was 93.6%.

Embodiment 2

[0216] On the grassland of the same type adjacent to Example 1 in Haiyan County, Qinghai Province, the test of eliminating chamaejasma was carried out, and the area of ​​spraying medicine was 10 hectares, and the specific medicine ratio was:

[0217] J2: 2,4-D isooctyl ester 34.2%;

[0218] K1: Gibberellic Acid A 3 0.1%;

[0219] L1: Ethylene glycol 3.0%;

[0220] M1: lubricating oil I (SAE: 15W-60, API: CD) 62.7%;

[0221] Spray time, use mechanical equipment, spray mode are with embodiment 1. The application rate is 1050ml / ha. The leaves of St. chamaejasma wilted 5 hours after spraying and died 50 days later. In the second year, the mortality rate of the marked chamaejasma plants was 92.9%.

Embodiment 3

[0223] On the grassland of the same type adjacent to Example 1 in Haiyan County, Qinghai Province, the test of eliminating chamaejasma was carried out, and the area of ​​spraying medicine was 10 hectares, and the specific medicine ratio was:

[0224] J3: 2,4-D isobutyl ester 34.2%;

[0225] K1: Gibberellic Acid A 3 0.1%;

[0226] L1: Ethylene glycol 3.0%;

[0227] M1: lubricating oil I (SAE: 15W-60, API: CD) 62.7%;

[0228] Spray time, use mechanical equipment, spray mode are with embodiment 1. The application rate is 1050ml / ha. Four hours after spraying, the leaves of St. chamaejasma wilted and died 50 days later. In the second year, the mortality rate of the marked chamaejasma plants was 93.3%.

Abstract

The invention discloses a drug complex. The drug complex is characterized by comprising 30 to 60 wt% of one or more 2,4-D esters, 0.01 to 5 wt% of gibberellin, 0.1 to 5 wt% of one or more of diethylene glycol, dimethylformamide, dimethylformamide, dimethylacetamide and dimethyl sulfoxide, and the balance lubricating oil. The drug complex has the advantages of high selectivity of euphorbia, high eliminating effects, good drug stability, low drug dose and high drug efficacy.

Description

technical field [0001] The invention relates to a compound drug, in particular to a compound drug for eliminating chamaejasma, as well as its preparation method and application. Background technique [0002] my country's natural grassland area is 360 million hectares. The existence of these grasslands, on the one hand, supports the development of animal husbandry in ethnic minority areas, and on the other hand, it is also a major part of the ecological construction in western my country. According to relevant research data, 90% of my country's natural grasslands are degraded, 30% are seriously degraded, the yield of forage grass is reduced, and the ability to carry livestock is reduced. Among the five major factors causing grassland degradation, poisonous weeding is the second most serious factor harming grassland after desertification. Poisonous weeds are mainly distributed in my country's Inner Mongolia, Xinjiang, Ningxia, Qinghai, Tibet, Gansu, Sichuan, and Yunnan provi...
