All Flashcards
What is the goal of IPM?
To reduce pest populations to acceptable levels rather than complete eradication.
Why is IPM considered a flexible system?
It combines multiple control methods and can be adapted to various settings.
How does increased biodiversity aid in pest control?
It supports a variety of natural predators, which can reduce the need for chemical controls.
How does intercropping enhance natural pest control?
It increases biodiversity and confuses pests, making it harder for them to find and infest crops.
Why is IPM a key component of sustainable agriculture?
It minimizes environmental impacts while maintaining crop yields.
Why are chemical controls considered a 'last resort' in IPM?
To minimize harm to non-target organisms and reduce environmental pollution.
What role do barriers play in physical pest control?
They prevent pest access to crops, acting as a fortress against pests.
How does crop rotation disrupt pest life cycles?
By changing the crops grown, it prevents pests from establishing a stable food source.
What is the relationship between ecosystem health and pest control?
Healthy ecosystems with high biodiversity are more resilient to pest outbreaks.
What are the benefits of using beneficial insects?
They control pest populations naturally, reducing the need for chemical pesticides.
How can promoting biodiversity support sustainable pest management?
Biodiversity enhances natural pest control by providing habitat for beneficial insects and creating more stable ecosystems.
How does reducing pesticide use contribute to sustainability?
It protects soil health, water quality, and biodiversity, and reduces the risk of pesticide resistance and harm to non-target organisms.
How can farmers reduce pesticide drift?
Use drift-reducing nozzles, apply pesticides during low-wind conditions, and establish buffer zones around sensitive areas.
How can farmers improve soil health for sustainable pest management?
Use cover crops, reduce tillage, and incorporate organic matter to improve soil structure, fertility, and water retention, enhancing plant resistance to pests.
How can precision agriculture contribute to sustainable pest management?
Precision agriculture uses technology to monitor crop health, pest populations, and environmental conditions, allowing for targeted and efficient pest control interventions.
How can farmers use trap crops in IPM?
Planting a more attractive crop near the main crop can draw pests away, protecting the main crop from infestation.
How can farmers promote beneficial insect habitats?
Plant flowering plants and maintain hedgerows to provide food and shelter for natural predators and pollinators.
How can farmers use pheromone traps for pest control?
Pheromone traps attract and capture pests, disrupting their mating and reproduction cycles.
How can farmers implement conservation tillage for sustainable pest management?
Conservation tillage reduces soil disturbance, preserving soil structure and organic matter, which supports beneficial soil organisms and enhances plant health.
How can farmers use push-pull strategies in IPM?
Using repellent plants ('push') to drive pests away from the main crop and attractive plants ('pull') to lure pests to a trap crop.
What are the consequences of relying solely on chemical pesticides?
Development of pesticide resistance, harm to non-target organisms, soil and water pollution, and disruption of natural pest control mechanisms.
How does increased biodiversity affect pest outbreaks?
Increased biodiversity leads to more stable ecosystems that are less susceptible to pest outbreaks due to a variety of natural predators.
What is the effect of intercropping on pest populations?
Intercropping confuses pests, reduces their ability to find host plants, and provides habitat for beneficial insects, leading to reduced pest populations.
What are the effects of pesticide use on human health?
Pesticide exposure can lead to acute poisoning, chronic health problems (e.g., cancer, neurological disorders), and endocrine disruption.
How does climate change affect pest management?
Climate change can alter pest distribution, increase pest reproduction rates, and disrupt the effectiveness of traditional control methods.
What are the environmental consequences of soil degradation from conventional agriculture?
Soil degradation reduces soil fertility, increases erosion, decreases water infiltration, and reduces carbon sequestration, leading to decreased agricultural productivity and environmental damage.
How does the loss of natural habitats affect pest control?
Loss of natural habitats reduces the populations of natural predators and beneficial insects, increasing the reliance on chemical pesticides and disrupting natural pest control mechanisms.
What is the impact of pesticide runoff on aquatic ecosystems?
Pesticide runoff contaminates water sources, harms aquatic organisms, disrupts food webs, and can lead to bioaccumulation and biomagnification of pesticides in higher trophic levels.
How does overuse of fertilizers affect pest outbreaks?
Overuse of fertilizers can create imbalances in plant nutrition, making plants more susceptible to pest attacks and increasing pest reproduction rates.
What are the long-term effects of pesticide resistance in pest populations?
Pesticide resistance reduces the effectiveness of chemical controls, leading to increased pesticide use, higher costs for farmers, and greater environmental impacts.
