Disadvantages of Biological Control Biological control agents are expensive to find. The greatest expenditure occurs during the field study and the early testing stage, which must be carried out abroad. There may not even be suitable agents. Potential agents are also costly to test for specificity.
Biological control can be less or more expensive than pesticides. You can incur significant expenses studying, choosing, testing and breeding a bioagent. However, in cases where bioagents are applied to low-level pest populations, pest control can be long-term and economical. Some fungi attack insects and kill them.
A fungal spore penetrates the insect and grows all over it. It takes about a week for the insect to die. Fungi are cost-effective, unless a high application rate is needed for severe insect infestations. A major disadvantage of biological pest control may be that it takes a long time to actually control the pest population.
Controlling pests with their natural enemies, including parasites, predators, diseases %26 that compete with organisms, is called biological control. It is an alternative to the use of broad-spectrum pesticides, which kill beneficial insects as well as pest organisms. , it is an environmentally friendly method %26, it does not introduce pollutants into the environment. The ladybug acts as one of the biological control agents, which is safe for both the environment and soil and water.
When it comes to the biological method of pest control, it requires a lot of dedication and patience. Ultimately, biological pest control has its own advantages and disadvantages, as it remains a new method of controlling the pest population. Unlike the chemical process, the biological control pest does not leave any type of residue as its sequelae. Further improvement in the microbial control activity of entomopathogenic fungi can be expected through their combination with other interventions and technologies, the use of other biological control agents, the use of environmental manipulation to favor infection processes, and the use of targeted pests to aid in the spread of mushroom.
While the chemical process of getting rid of pests has proven successful, success stories in controlling the pest population through a biological process are very few. Biological control is described as the practice by which the undesirable effects of a pest organism are reduced through the activity of another organism that is not the host, is not a pest, or is not a human being. Biological pest control is the use of natural predators as agents to attack weeds. The biological control agents are insects, but sometimes fungi are used, bacteria %26 nematodes, some fungi attack insects %26 kill them, the fungal spore penetrates the insect %26 grows along it, The insect takes about a week to die.
There have also been cases where the biological control agent, when introduced and not native, ultimately becomes a pest. The development of host resistance is not a problem, biological pest control is compatible with most other control techniques (except sometimes the use of insecticides %26 herbicides), biological control reduces the competitiveness %26 of the reproductive capacity of the weed, making it more manageable. The great benefit of this method is its selectivity, there is a restricted danger of damage to non-target plant species, biological control does not create new problems, such as conventional pesticides, selectivity is the most important factor with respect to the balance of agricultural ecosystems because a large damage to non-target species objective can lead to the restriction of populations of natural enemies. It can be more difficult for a non-professional person to achieve biological control, given the many variables involved and the specialized knowledge of pests, bioagents, and environmental conditions that are often needed to succeed.
Biological control is the attractive alternative to agrochemicals, the use of environmentally friendly alternatives to chemical pesticides is absolutely necessary in agriculture, no chemicals are used, so there is less pollution, disruption of the food chain %26 risk for people who eat the foods that have been sprayed. It is an alternative to pesticides and poisons that can offer a few different advantages and disadvantages. . .
