You may incur significant expenses studying, choosing, evaluating and. Biological control can be cheaper or more expensive than pesticides. You may incur significant expenses to study, choose, test and reproduce a bioagent. However, where bioagents are applied to low-level pest populations, pest control can be long-term and cost-effective.
Some fungi attack insects and kill them. A fungal spore penetrates the insect and grows along it. It takes about a week for the insect to die. Fungi are cost-effective unless a high application rate is needed for intense insect infestations.
Biological control doesn't offer a simple and complete answer to all insect problems in the garden, and it's certainly not magic. It can be fickle, you can't control any natural enemy, you let loose in an ecosystem. While it's supposed to control a pest, your predator will switch to a different target, it may decide to eat your crops instead of the insects that infest them, but when you introduce a new species into the environment, there is a risk of disrupting the natural food chain. Chemical pesticides are very effective against pests that feed directly on crops over a very large area, but they must be used safely and the economic problems of using modern pesticides must be largely taken into account.
In the chemical process, being full of pesticides, it can easily destroy plants, which also bear fruit, rotting them. Once potential biological control agents have been identified, they are tested overseas to ensure that they are host-specific, meaning they will not attack any plant other than the weed to be controlled and, therefore, will not become a pest if introduced into Australia. 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 both beneficial insects and pest organisms, it is an environmentally friendly method %26: it does not introduce contaminants into the environment.
The biological process of pest control may seem easy, but it's not, especially if it's your first time doing so. Because of the potential health risks associated with the use of pesticides, the cost of developing new pesticides has increased at an increasingly rapid rate in recent years. 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 of the reproductive capacity of weeds, making it more manageable. Biological pest control is a safe method, since it only focuses on weeds and leaves only fruits and others. These natural enemies are known as pest control agents and include predators, parasites and organisms. It is highly specific for a pest, can be cheaper or more expensive than pesticides.
You can incur significant expenses studying, choosing and testing %26 reproduction of the bioagent, a long-term solution if equilibrium is established, biological pest control is economical in the long term %26 can be used in a greenhouse. Biological control is a slow process, it takes a long time.26 of patience for biological agents to work their magic on the pest population, while other methods, such as pesticides, offer immediate results. The advantage of this is the long-term effect that biological control provides. However, many IPM programs have been unable to go beyond the first stage of developing sampling methods and economic thresholds for pesticide application.
Biological control is unpredictable. Its unpredictability lies primarily in the fact that natural enemies depend on environmental conditions. The deployment of BCAs in a new environment requires a lot of research to obtain the desired results due to climate limitations. .
