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 chemical and labor costs saved in this way can rather be used for the control of invasive plants where there are no effective biocontrol agents, or in areas where biological control is less effective. 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. The biological control agent (BCA) can be deployed in the agricultural ecosystem, so as not to harm non-target pests, it depends on appropriate host specificity tests that determine the potential range of hosts. 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.
Another benefit of the biological control method is the environmental safety of BCAs, the pest is unable (or 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. 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. 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. environmentally friendly method & does not introduce pollutants into the environment.
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. Biological pest control does not have an adverse effect on human health or the environment, it is self-sustainable, it can be cost-effective, when the cost of testing & has been met by introducing control agents, the ongoing costs are small, it is not necessary to find% 26 identify each individual weed to be treated, a effective agent will look for all the right plants from the weed. 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.
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. Weed-related native and cultivated plants are exposed to the biological control agent to see if they are also attacked. 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. In addition, the disadvantages of using entomogenic fungi as biocontrol agents against arthropod pests have been absent by the need for specific environmental conditions (humidity greater than 80% and above) during the prolonged period in which the fungi are required to germinate the spores and then penetrate the surface of the cuticle of arthropods.
The ladybug acts as one of the biological control agents, which is safe for both the environment and soil and water. . .
