Specifically, ethics tells a branch of philosophy that it is comparable to a society that seeks to parse and explain existing thoughts and ideas about its usefulness. Agriculture is one of the most important human activities that it is very necessary to observe the ethical aspect. These aspects include human (as a component), animals, the environment, society, economics and politics. The most important ethical issue is the production, consumption and food business in the presence of the hungry, and the health of the food is also a very important moral issue. In relation to weed plants, if a farmer controls a weed with a wide root system or with a high distribution potential, it prevents the spread of losses to others, which is an example of the external sample of profit. On the other hand, if farmers fail to control some weeds, other farmers will be at risk of external infection, and additional costs of weed control or yield loss will apply to them. In addition, widespread use of chemical pesticides against weeds may reduce water quality, increased protests, the environment and the cost of treatment. Accordingly, the responsibility of the future as well as of the present generations will make us committed to preserving natural resources (sustainable management of weeds) and avoiding irreversible changes. Therefore, the ethical look is a holistic view, and it is not merely a set of methods; it is a view that does not focus solely on production and consider the whole system, and human beings are also part of this system, so stepping In line with the sustainability of agriculture, this attitude is realizing the goals.
