Problems solved by technology

[0003] At present, the prevention and control of chamaejasmin mainly uses single agents such as glyphosate, 2,4-D, and serotonin, and prior patents have made inventions in removing chamaejasmin. Leaf pastures are more harmful, destroying the biodiversity of pastures, resulting in single pastures in pastures, resulting in imbalanced livestock nutrition, and hindering the development of animal husbandry

Abstract

The present invention relates to herbicide, and is especially one kind of re-compounded Langdu preventing and killing herbicide. The re-compounded herbicide is re-compounded with 2, 4-D butyl 50-94 wt%, 3, 5, 6-tichloro-2-pyridyl oxyacetic acid 5-50 wt%, gelatin 0.5-2 wt% and sodium octodecyl sulfonate 0.5-2 wt%, and through mixing the materials through stirring, bottling and sealing to obtain the product. The present invention has the advantages of specificity of killing Langdu, easy operation, small use amount, low toxicity, low residue and high efficiency.

Description

technical field [0001] The invention relates to a compound herbicide, in particular to a compound herbicide for controlling chamaejasma. Background technique [0002] Among the five major factors causing grassland degradation in my country, poisonous weeding is the second most serious factor harming grassland after desertification. 36.369 million hm in Qinghai Province 2 Among the natural grassland area, the degraded grassland area is 530×10 4 hm 2 , poisonous weed type degraded grassland is 262.11×104 h m 2 , accounting for 49.5%, of which chamaejasmin occurred in an area of ​​73.94×10 4 hm 2 , accounting for 28.2% of the area of ​​poisonous weed-type degraded grassland. Chamaejasma belongs to Daphneaceae, commonly known as "mantou flower". It is one of the most serious poisonous weeds in natural grasslands in Qinghai Province. It grows strong, reproduces quickly, and has luxuriant branches and leaves in summer. It competes with fine pastures for space, soil and wate...
