Crop protection is a fundamental method to ensure the protection of crops from various harmful entities, such as pests and weeds. This method helps farmers control damage to crops with high yields.
It involves implementing strategies to minimise crop damage from pests, diseases, and environmental stresses, ensuring optimal yield and quality.
Methods of Crop Protection Management
There are so many methods of crop protection by which farmers can protect their high-yielding crops.
1. Weed Control
Weeds are the unwanted plants that grow with the crops. These plants also collect the essential nutrients, sunlight, and water from the same resources that are essential for the crops.
- Weeds affect crop growth, and as a result, crop yield decreases.
- Farmers remove these crops by following the process of weeding.
- The main aim of weeding is to save the crops from weeds.
- Ploughing the field, manual plucking, and spraying weedicides are some major processes to remove weeds from the field.
- Chemical substances are really essential, as they control the weed expansion.
- Examples of some weeds: Amaranthus, Cyperus rotundus, Bermuda grass, etc.
2. Pests and Insect Control
Insects and pests are the main cause of crop damage and loss of yield. These agents ruin the entire crop by eating the major portion of the grains.
- Insects and pests can reduce the crop yield by around 30-50% per year.
- The simple way is to spray insecticides and pesticides to prevent crop damage.
3. Disease Control
Pathogenic diseases harm crops. They are caused by bacteria, fungi, and viruses.
- These diseases affect different parts of the crops in different ways.
- Farmers can protect their crops from these diseases by using pesticides and biocontrol agents.
- This is the part of crop protection management that farmers should do before and during cultivation.
4. Storage Control
Harvested crops may be damaged by insects, rodents, and microorganisms during storage.
- Proper drying of grains
- Use of fumigants
- Clean and dry storage structures
Products of Crop Protection
Here are the different crop protection products as mentioned below.
- Fungicides kill fungi and their spores. It helps in preventing their growth and damage to crops. They do not work against bacteria, viruses, or nematodes.
- Herbicides kill unwanted plants like weeds and grass. It helps the crops to get the nutrients that they need for good growth. They are also known as weed killers.
- Insecticides kill insects that can harm the crops by repelling, harming, or killing them.
- Nematicides are chemicals that kill nematodes. They are the worm-like parasites that attack plant roots in the soil. It makes the crops more susceptible to bacterial and fungal damage.
Effect of Climate Change on Crops
Here are some effects of climate change on crops, as mentioned below:
- Climate change affects crop protection just as it affects various aspects of human life.
- The ecosystem of weeds, pests, and diseases is influenced by climate change, as rising levels of carbon dioxide contribute to the increase in global temperature.
- It is crucial for researchers and agricultural professionals to scrutinise these changing circumstances and their implications for agriculture.
- Research is needed to understand how global warming affects insect communities and herbivory rates.
Importance of Crop Protection in Agriculture
- Crop protection helps prevent yield loss due to pests, various diseases, and different environmental stresses.
- It can help farmers to increase production rate in smaller areas.
- It helps to preserve the biodiversity and nutrient levels in the soil.
- It can help to improve the food quality and also cut down the food costs.
