Embodiment 1

[0026] In the small-area experiment of controlling Pedicularis kansuensis Maxim in Qilian Mountains, 2,4,D-butyl ester 336 / hm 2 , accounting for 32%, ethephon 15.75g / hm 2 , accounting for 1.5%, engine oil 698.25g / hm 2 , account for 66.5%, mix evenly, use the knapsack type motorized sprayer that is equipped with special nozzle, (this special nozzle applies for a patent simultaneously on the same day), carry out stoste spray, per hectare consumption 1150-1200 milliliters. After 25 days of spraying, the plants of Artemisia gansuensis injured by the drug began to die, and the mortality rate of the marked plants of Artemisia gansuensis reached 92.5% in the second year.

Embodiment 2

[0028] In the small-area test of controlling Pedicularis kansuensis Maxim in Qilian Mountains, 378g / hm of 2,4,D-butyl 2 , accounting for 36%; ethephon 147g / hm 2 , accounting for 14%, engine oil 525g / hm 2 , accounting for 50%, mix evenly, use a knapsack motorized sprayer equipped with a special nozzle to spray the stock solution, and use 1150-1200 ml per hectare. After 25 days of spraying, the damaged plants of Artemisia gansuensis began to die, and in the second year, the death rate of marked plants of Artemisia gansuensis reached 97%.

Embodiment 3

[0030] In the small area test of controlling Pedicularis kansuensis Maxim in Qilian Mountains, 376g / hm of 2,4,D-butyl 2 , accounting for 35.8%; ethephon 36g / hm 2 , accounting for 3.4%; engine oil 638g / hm 2 , accounting for 60.8% and mixed evenly, use a knapsack motorized sprayer equipped with a special nozzle to spray the stock solution, and use 1150-1200 ml per hectare. 25 days after the application of the pesticide, the plants of Artemisia gansuensis injured by the drug began to die, and the mortality rate of the marked plants of Artemisia gansuensis reached 95% in the second year. The test results showed that after 3 years of killing A. gansuensis, the importance value of A. gansuensis in the degraded grassland decreased from 60.1% to 3.5%. Density, coverage and above-ground biomass have substantially increased, occupying the dominant position in grassland, and the vegetation functional group structure of degraded grassland has basically recovered to the level before gras...

Abstract

The present invention relates to herbicide, and is especially herbicide for killing resupinate woodbetony. The herbicide for killing resupinate woodbetony consists of 2, 4, DB 21-36 wt%, ethephon 1-15 wt% and engine oil 49-78 wt%. It has resupinate woodbetony killing rate as high as 92.5-97 % to raise grass producing capacity.

Description

Technical field: [0001] The present invention relates generally to herbicides, and more particularly to herbicides suitable for use on plants of the genus Artemisia. Background technique: [0002] Pedicularis L is a perennial or annual herb belonging to the family Scrophularicaceae. There are more than 500 species in the world, most of which are distributed in the cold temperate zone and high mountains in the northern hemisphere. There are more than 340 species in our country, mainly distributed in the southwest mountainous area and the northwest region. They are born in alpine meadows, shrubs or grasslands, mountains, forest margins or under forests. The plants of Artemisia spp. , has strong competitiveness for light, water, fertilizer and other resources. In Inner Mongolia, Gansu, Qinghai and other provinces and regions, the spread of Artemisia genus plants has posed a serious threat to the safe production of livestock. Poisoning incidents of cattle and sheep accidentall...
