In the previous article I finished talking about the chemical method in weed control, and there I said that it should be remembered that this method is not the only and by no means the most important, because there are biological controls that are often more effective.
▶ As I have mentioned, the elimination or reduction of undesirable plants to economically acceptable levels through the use of specific organisms is a positive option from the environmental point of view.

Hence, in recent years, in addition to chemical control, biological control has begun to be used, by means of biological agents, namely microorganisms of multiple species, where in specific cases the combination of more than one microorganism that does not affect the environment is used.
Biological agents, once established, can control undesirable plants of concern in places inaccessible to humans due to their high dispersal ability.
Biological control is quite specific, whereby its practice is successful in eliminating a weed species. Its use can be useful when a certain weed species is prevalent.
Biological control is generally economically feasible, especially if the agent can be multiplied locally for later release.
