Crop protection before & during the cultivation
Weeds are unwanted plants growing along with the crops. They steal the nutrients provided for crops and affects the growth of the crops. Few examples are Cyperinus rotundus (motha), Bermuda grass etc. The weeds could be controlled by weedicides and also could be uprooted using machines without affecting the main crop. Other factors, which affect the crop is pests and rodents. They could ruin the whole crop and eat up the large portion of grains. Pathogenic diseases are another type of crop-damaging factors. Microorganisms like bacteria, fungi, and viruses affect different parts of the crop through various means. Crops could be protected from these pests and diseases by using pesticides and bio control agents. These are crop protection management, which should be followed before and during the cultivation.
Crop protection after the cultivation
Crop protection after the cultivation
The cultivated grains must be stored safely to avoid product loss. Chances of grain loss are much higher during this time than before cultivation. Therefore, methods of protection need to be better. Common pests and rodents and some environmental conditions like humidity and temperature are the responsible factors for the loss. Certain precautions help us to prevent from this loss. Before storing the grains, it should be cleaned and dried completely in sunlight as it helps in protecting the crops from fungal growth, which is caused by the presence of moisture. Pests could also be killed by a method called fumigation.
