Weeds are one of the basic problems in agriculture that reduce the yield and quality of crops. The use of chemical methods to control weeds has been criticized because of their side effects on the environment and human health. For this reason, biological methods have been recognized as an effective and sustainable solution for weed control. In this article, biological methods for weed control are discussed.

1- Use of predatory animals: One of the biological methods to control weeds is the use of predatory animals. Some predatory animals such as lizards, owls and wild cats recognize weeds as their food source and destroy these plants.

2- Use of bacteria and fungi: some bacteria and fungi can act as weed control agents. For example, rhizobium bacteria can compete with weeds for their food resources and reduce weed growth. Also, fungi such as powdery mildew can act as weed control agents in many crops including wheat, barley and potatoes.

3- Use of competing plants: competing plants can compete with weeds in competition for their food resources and reduce the growth of weeds. For example, legumes such as barley and wheat can compete with weeds for light, water, and nutrients.

4- استفاده از تغییر شرایط محیطی: تغییر شرایط محیطی مانند تنظیم سطح آب، حراج و ایجاد رطوبت برگ‌ها می‌تواند باعث کاهش رشد گیاهان هرز شود.

استفاده از رقابت گیاه زراعی و گیاه هرز:

In this method, to prevent, control or reduce the establishment of weed plants, the plant's changeable abilities such as growth, habits, adaptations, and the ability of weed plants to compete are used.
ماده ای زنده و دارای فعالیتهای زیست شناختی است،بنابراین رقابت آن با گیاه دیگر به عنوان یكی از روشهای بیولوژیكی مورد بحث قرار می گیرد.

The competition of plants. The ability to compete and the strength of the plant is one of the important criteria for selecting and cultivating improved plant varieties. Plants with the ability to grow faster have advantages over slow-growing plants that are sensitive to weeds. Called pollinators, they are invaluable in any weed control program. They compete well with weeds for food storage, soil moisture, sunlight, and carbon dioxide. Corn, corn on the cob, soybeans,
And cowpeas are important plants that have the ability to compete with weeds and grow much faster than them, become taller and shade the space between the rows sooner.
As a result, weed plant growth is suffocated. The very serious limitation of this method is that the environmental requirements of crops and weeds are very similar. This method can be combined with Rieger's weed control methods.
