hat is the primary focus of pest control in agriculture?
Pest control in agriculture primarily aims to prevent damage caused by insects, rodents, and other organisms to crops. By managing pest populations effectively, farmers can protect their crops and ensure optimal yield and quality.
What strategy involves introducing natural predators or parasites to manage pest populations?
Biological control strategy involves the introduction of natural predators or parasites to manage pest populations. This method leverages the natural enemies of pests to reduce their numbers, minimising the need for chemical pesticides and promoting ecological balance.
What is the primary goal of disease control in crop management?
The primary goal of disease control in crop management is to prevent and manage crop diseases effectively. By implementing disease control measures, farmers aim to minimise crop damage, preserve yield and quality, and ensure the long-term health of their crops.
Which method involves using chemical agents to control fungal and bacterial diseases?
Fungicides and bactericides are chemical agents used to control fungal and bacterial diseases in crops. These substances are applied judiciously to prevent the spread of diseases and protect crop health without harming the environment or human health.
What does Integrated Crop Management (ICM) aim to achieve?
Integrated Crop Management (ICM) aims to achieve sustainable and efficient crop production by integrating various management strategies. It emphasises holistic approaches that combine cultural, biological, and chemical methods to optimise resource use, minimise environmental impact, and ensure crop health and productivity.
