Major Causes of Crop Diseases and Their Preventive Measures.

Major Causes of Crop Diseases and Their Preventive Measures.

08 Feb 2022

Plants, like all living things, are subject to several diseases. Crop disease is defined as any adverse departure or variation from the physiological systems' normal functioning – according to seed dressing experts in Halbury. As a result, sick plants' regular life processes and crucial functions are disrupted. In this blog, we will discuss the major causes of crop diseases and their preventive measures.

Causes of crop diseases
The disease typically appears and spreads from one season to another, based on the presence of a specific pathogen, as well as climatic circumstances and crop variety features. Crop diseases manifest themselves primarily as a result of the type of their causative agent:

• Noninfectious or Abiotic disease agents
• Infectious or Biotic disease agents

Non-living environmental factors or poor agricultural management are examples of abiotic, or non-infectious disease agents. They can't be passed on to other plants. The following are a few examples of generally known abiotic agents:

• Extreme temperatures
• Moisture
• Wind
• Heavy raining
• Excess or lack of nutrients
• Flood or drought
• Soil compaction
• Inadequate water management
Chemical injuries caused by salts or pesticides

Biotic disease agents, often known as infectious diseases, are living creature pathogens capable of transferring illness from one host to another. Major pathogens include:

• Fungi, the most prevalent pathogens, are responsible for around 85% of plant illnesses; for example, the Puccina graminis tritici causes black or stem rust.

• Viruses are spread by vectors or attack plants through wounds. Just like, Apple mosaic virus infects plum, apple, and hazelnut trees.

• Bacteria; mutate and reproduce quickly; they enter by stomata or wound; for example, Erwinia amylovora causes Apple fire blight.

• Nematodes wreak havoc on crops, causing galls on the roots.

• Algae, in theory, do not cause considerable damage, although they can under some conditions.

Preventive measures
Saving yields and safeguarding crops from illnesses is a top priority for any farmer who wants to achieve the best possible outcomes. Knowledge has always been the first and most important step in crop protection. Every farmer must be aware of the crop's vulnerability to specific illnesses, as well as the abiotic factors that encourage disease incidence. More significantly, effective techniques are to take preventative actions like:

• Handling optimal planting & harvesting times
• Planting quality and healthy material
• Equipment disinfestation 
• Crop rotation
• Controlling plant nutrients according to crop requirements

There is one more aspect of disease farm management that might make a major impact. Regular crop and field monitoring, as well as timely response, might be a genuine lifesaver for any agricultural output.
