Abstract

The invention discloses a medicago sativa weeding agent, which comprises the following raw materials by weight: 50-60 parts of a 5% imazethapyr aqueous agent, 50-60 parts of 5% quizalofop-ethyl, 20-40parts of 33% pendimethalin emulsifiable concentrate, 20-40 parts of 48% trifluralin emulsifiable concentrate, 10-20 parts of a biological weeding agent, and 10-20 parts of a weeding agent aid. According to the present invention, the medicago sativa l weeding agent has advantages of simple formula and simple material obtaining, integrates the characteristics of conductive weeding agents and hormone-based weeding agents, can improve the economic benefits of planting, cannot produce environment pollution during the use, can prevent water from eutrophication, can improve the weeding effect, can protect medicago sativa from being damaged by weeds during the whole growth period after one applying, can reduce the environment pollution caused by pesticides, is safe and harmless to medicago sativaafter the use, and further is efficient, safe, economic and practical; and the preparation method is simple and is easy to perform.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to an alfalfa herbicide. Background technique [0002] Alfalfa (Medicago sativa) is an extremely important leguminous forage in the development of world agriculture and animal husbandry. It has the characteristics of wide adaptability, good palatability, high yield, and good forage quality. It is one of the first choice pastures for adjusting the structure of agricultural planting. However, at the initial stage of alfalfa establishment, it is very vulnerable to the invasion and harm of field weeds, mainly because alfalfa grows slowly at the seedling stage and takes a long time to cover the ground, while most weeds grow rapidly at the seedling stage of alfalfa, and they are different from the seedlings of alfalfa. Nutrients, water and light form a strong competition, thereby reducing the yield, quality and palatability of alfalfa. Regarding weed control in alfalfa field...
