Crops can be protected in various ways to ensure their healthy growth and minimize damage caused by pests, diseases, and other factors. However, there are certain methods that may not effectively protect crops. One such method is allowing animals to graze in the crop field.
1. Use of insecticides and pesticides:
- Insecticides are chemicals specifically designed to kill or repel insects. They are applied to crops to prevent insect infestation and damage.
- Pesticides, on the other hand, are substances used to control a wide range of pests including insects, weeds, and diseases. They help in reducing crop damage and increasing yields.
2. Proper fencing of the field:
- Fencing the crop field helps in keeping out large animals like deer, rabbits, and cattle that may damage or graze on the crops.
- This physical barrier prevents animals from accessing the crops, protecting them from being trampled, eaten, or destroyed.
3. Allowing animals to graze in the crop field:
- Allowing animals to graze in the crop field can result in significant damage to the crops.
- Animals like cows, goats, and sheep may eat or trample on the crops, leading to yield loss and reduced quality.
- They may also introduce weed seeds or spread diseases, further affecting the crop's health.
4. None of these:
- This option is incorrect because all the other methods mentioned (use of insecticides, use of pesticides, and proper fencing) can effectively protect crops.
Therefore, the correct answer is option 'C' - Allowing animals to graze in the crop field. This method can be detrimental to crop protection and should be avoided to ensure optimal crop growth and yield.
