Abstract

The invention belongs to the technical field of herbicides, and particularly relates to a compound preparation for controlling Radix Euphorbiae Lantu, and a preparation method thereof. The compound preparation comprises, by weight, 30-50 parts of 2,4-D-octyl ester, 5-25 parts of triclopyr, 0.5-2 parts of gelatin and 0.5-2 parts of sodium octadecyl sulfonate. Through reasonable proportioning and simple formula, the use of reagents limited by the Ministry of Agricultural Industry of China is avoided, the above herbicide has the characteristics of small dosage, high selectivity, high efficiency,safety and the like, the control effect can reach 95% or above, the herbicide not only has a good control effect on Radix Euphorbiae Lantu, but also is safe to other excellent pasture, and the biological diversity of grassland is protected.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a compound preparation for preventing chamaejasma and a preparation method thereof. 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, poisonous plants such as Stellera chamaejasme are widely distributed in the vast natural grasslands of our country, and Stellera chamaejasme accounts for 16% of the total grassland area in alpine grasslands, and there is a tendency to gradually expand. [0003] Stellaris belongs to the family Daphneaceae, with a well-developed root system. It is cold-resistant, drought-tolerant, turns green early, has strong vitality and strong stress r...
