Biocontrol & Organic Farming — NEET Biology
📚 Practice ConceptThe organic farmer holds the view that the eradication of the creatures that are often described as pests is not only possible, but also undesirable, for without them the beneficial predatory and parasitic insects which depend upon them as food or hosts would not be able to survive. Thus, the use of biocontrol measures will greatly reduce our dependence on toxic chemicals and pesticides. An important part of the biological farming approach is to become familiar with the various life forms that inhabit the field, predators as well as pests, and also their life cycles, patterns of feeding and the habitats that they prefer. This will help develop appropriate means of biocontrol.
Which of the following statements regarding the importance and approach of biocontrol methods are NOT correct? S1: Biocontrol methods are increasingly favored because they are often more cost-effective and faster acting than synthetic pesticides. S2: Organic farming emphasizes a holistic approach to pest management, aiming to maintain biodiversity rather than pest eradication. S3: Synthetic pesticides typically offer specific targeting of pests, minimizing harm to beneficial organisms in an ecosystem. S4: The reliance on chemical methods in conventional farming can lead to pollution of soil, groundwater, and crop plants. S5: Understanding the life cycles and feeding patterns of both pests and predators is crucial for developing effective biocontrol strategies. S6: Biocontrol measures aim to completely eliminate pest populations to ensure maximum crop yield.
