Study Notes
Weed Control
- Weeds are removed from cultivated fields during early crop growth to prevent competition for water, nutrients, and light, ensuring optimal crop growth and yield.
Insect Pests
- Insect pests generally affect crop plants by feeding on them, causing physical damage, and transmitting diseases.
Pathogens
- Pathogens are microorganisms that cause diseases in plants, including fungi, bacteria, and viruses.
Integrated Pest Management (IPM)
- One common method to control weeds, insects, and diseases is through Integrated Pest Management (IPM), which involves using a combination of techniques such as cultural, physical, biological, and chemical controls.
Consequences of Excessive Pesticide Use
- Excessive use of pesticides can lead to environmental pollution, development of pesticide-resistant pests, and harm to beneficial organisms like bees and other pollinators.
Consequences of Uncontrolled Weeds
- If weeds are not controlled at the appropriate time in field crops, they can reduce crop yields, lower crop quality, and interfere with harvesting operations.
Controlling Weeds, Insects, and Diseases
- Weeds, insects, and diseases can be controlled in crop protection management through a combination of methods, including cultural practices, biological controls, and targeted chemical applications.
