You can incur significant expenses studying, choosing, testing and. 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.
The advantages of biological control, ecology and applications are many. Biological control agents are environmentally friendly and have no side effects for humans. These methods are also comparatively cheaper than other agrochemicals, such as pesticides and insecticides. These methods are also easy to use, available and can be used in any season of the year.
The most important use of biocontrol agents is perhaps that they help reduce the use of chemicals and pesticides that have harmful effects on humans. There are also other disadvantages to using biocontrol methods. The use of biocontrol agents causes a significant and noticeable deterioration in the quality of the products. Biocontrol agents do not eradicate all pests and are a useful and economical tool for pest control only when used on a large scale.
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. In order to choose a successful biological control program, it is crucial to identify the pest along with its population levels and the circumstances of the infestation. The ladybug acts as one of the biological control agents, which is safe for both the environment and soil and water. Another benefit of the biological control method is the environmental safety of BCAs, the pest cannot (or is very slow) to develop resistance, biological control can be cost-effective, its effectiveness is based on self-perpetuation & of self-propagation, therefore, if we establish a control agent in a specific area, it will reduce the target pest at an acceptable threshold for quite some time.
It is highly specific to a pest, can be less or more expensive than pesticides, can incur significant expenses studying, choosing, testing & raising 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. It is difficult & sometimes expensive to develop biological control in the field because it requires highly qualified scientific personnel. There is relatively less investment in biological control research compared to chemical pesticides, The & variation changes in the behavior of natural enemies that can be caused by breeding conditions are multiple, this variation leads to inconsistent results in biological control. Unlike chemical pesticides, biological control agents, also called bioagents, leave no lasting residues that remain in the environment.
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. The biological control method of pest control does not use chemicals, it uses many organisms that are the predators or parasites of the pest, the pest is the organism that causes harm to people and their crops, biological control should be implemented whenever possible because it does not pollute the environment. It is the negative impacts of chemical pesticides that have led to new attention to a greater emphasis on biological control agents with respect to the use of fungi through the use of natural arthropod pathogens. Biological control is a slow process, it takes a lot of time & patience for biological agents to work their magic on the pest population, while other methods such as pesticide work offer immediate results.
The advantage of this is the long-term effect that biological control provides. Once potential biological control agents have been identified, they are tested abroad to ensure that they are host-specific, that is, they will not attack any plant other than the herb to be controlled and, therefore, will not become a pest if introduced into Australia. The ability to self-perpetuate is an interesting advantage of the biological control method, BCAs will increase in number & of propagation, because BCAs self-propagate & by dispersing, pest control is also self-perpetuating, this is quite important with respect to the economic viability of control. Biological control has a slow action, lacks the immediacy of chemical control, therefore, for the required period until natural enemies control the pest population, pests may be present in intolerable populations, the agent may become a pest in itself, an input is needed frequent to maintain population balance and it has to be on a large scale.
Biological control agents are specifically targeted by harmful organisms and do not kill beneficial organisms in soil. . .
