Compare the use of chemical and biological control of pest?
Biological control takes more roll in Integrated pest Management system where we are adopting the natural based methods inclusive of of Mechanical, Physical, Agronomical control methods, besides the Bio-control methods. comparatively the chemical control methods led to the following adverse effects which can be prevented by adopting Bio-control measures. 1.Creating Resistance power on Pests 2. creation of resurgence power , 3, poisoning the plant products(Foodgrains, fodders like straw) so that it make ill effect on human's and live stock's health 4. polluting the Air, Water, Soil, 5. Chemical control Very expensive than Bio control methods
What reason might a farmer have for using biological control instead of chemical pesticides?
A farmer might choose biological control over chemical pesticides to minimize negative impacts on the environment and human health, reduce chemical residues on produce, and promote sustainable agricultural practices. Biological control methods also have the potential for long-term pest management and are often more target-specific.
What is uses of biological chemical methods to change the DNA sequence of genes?
Rma
What are Advantage and disadvantage of four methods of pest control?
The four common methods of pest control are chemical, biological, cultural, and mechanical. Chemical methods are effective and fast-acting but can have harmful environmental and health impacts. Biological methods use natural predators, which are sustainable but may take longer to see results and can sometimes disrupt local ecosystems. Cultural methods promote practices that prevent pest infestations, making them environmentally friendly, though they require more effort and planning, while mechanical methods, like traps, are safe and precise but may not be practical for large infestations.
What uses biological and chemical methods to change the DNA sequence of gene?
Genetic engineering.
Does genetic engineering change DNA sequences using biological and chemical methods?
YES
Types of biological pest control?
There are basically three types of biological pest control i.e. Importation, Augmentation, and Conservation. All these home pest control methods are pretty useful in various pest control activities like rat extermination, cockroach pest control, mice control, fleas control etc. You can easily implement these methods one by one.
Why are preventive measures and biological control methods be preferred for crop protection?
Preventive measures and biological control methods are preferred for crop protection because they are typically safer for the environment, humans, and beneficial organisms. They also help to reduce the reliance on chemical pesticides, which can have harmful effects on ecosystems and human health. Additionally, they can be more sustainable in the long run by promoting natural pest control mechanisms and reducing the development of pesticide resistance.
Why should preventing measures and biological control methods be preferred for protecting crops?
In plants, disease are caused by microorganisms, and these disease causing microorganisms are called pathogens. Some preventive measures and biological control methods are used to get rid of these pathogens, which are : (a) Simple (b) Economic (c) Minimize pollution without affecting the soil quality.
What is the difference between natural biological method of clean up and man made?
The difference between natural biological and man made methods is that the later uses chemical processes which can be harmful to the environment. Biological methods use evaporation, oxidation, and biodegradation to safely cleanup
What are the methods of weed control?
Two types of methods are used to control pests. Natural pest control methods are employed to reduce or eliminate infestations through companion planting, crop rotation, predatory animals or repellent plants, but without harming humans, crops and other organisms. In contrast, chemical pest control methods often employ harsh pesticides that may be applied systemically (targeting where plants are commonly ingested by pests) or sprayed aerially, but with harmful and residual effects on both human and animals living within the area.
How does biological control and genetic modification be used instead of pesticides and herbicides to control pests that destroy crops?
Biological control involves using natural enemies of pests, such as predators or pathogens, to keep pest populations in check. Genetic modification can be used to engineer crops that are resistant to pests, reducing the need for chemical control methods. These approaches can be more environmentally friendly and sustainable than using pesticides and herbicides.
