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. Biological control requires more intensive management and planning.
May take longer, require more records, and require more patience and education or training. There are some disadvantages to the use of biological control agents. First, they may be less effective than chemical pesticides in controlling pests. Second, they may take longer to be effective than chemical pesticides.
Finally, they can be more expensive than chemical pesticides. Most natural enemies used in biocontrol attack a very limited number of species. Therefore, cases where a specific biocontrol practice interferes with other ongoing pest control practices are relatively rare. In contrast, chemical control practices often interfere with biocontrol due to the broad-spectrum effects of many pesticides.
This makes it difficult to integrate biocontrol practices into pest control systems that rely heavily on pesticides. There are many different types of biological control agents, including predators, parasites, and pathogens. 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 & risk for people who eat the foods that have been sprayed. 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.
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. 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. Often, the results of using biological control are not as dramatic or immediate as the results of using pesticides. 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.
Pests do not become resistant, there is no environmental pollution, if the biological control body is introduced, it is not necessary to re-introduce it, chemical pesticides must be used repeatedly, therefore, more expenses & time spent, biological control limits the further use of pesticides. 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. Although it is much more difficult to use entomogenic fungi for biological pest control in the field, it holds promise for pests that have an aquatic stage, such as the use of insect fungal pathogens for the control of diseases such as malaria that depend on insect vectors. Using biological control in your home garden requires knowledge, patience and motivation, but it can also reap great rewards.
Biological control is unpredictable, its unpredictability lies mainly in the fact that natural enemies depend on environmental conditions. Deploying BCAs in a new environment requires a lot of research to achieve desirable results due to climatic constraints. The biological control method is safe for the environment, this method offers less risk of residues in the food chain, biological control is more suitable for exotic pests that are not closely related to native beneficial species, biological control is less expensive than chemical control. It is an alternative to pesticides & poisons, when you eliminate the organism from the food web, it can disturb everyone else around it, so you must be very careful, biological control is a better and safer method of control than the use of pesticides.
Biological pest control is a very specific strategy, whichever predator is introduced it will only control the population of the pest they are intended to attack, making it an ecological alternative to chemical or mechanical control methods, while chemicals that kill weeds can destroy fruit plants, Biological control allows fruit to be left uninterrupted while weeds are destroyed. Controlling pests with their natural enemies, including parasites, predators, diseases & 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. an environmentally friendly method &, does not introduce pollutants into the environment. .
