Preventing Plant Pathogens in Farming: Tips and Strategies

Crop loss due to plant pathogen is a significant issue for farmers worldwide, with an estimated loss of 14.1% or USD 220 billion annually. These losses can be caused by a variety of biotic and abiotic factors, including oomycetes, fungi, viruses, bacteria, nematodes, and viroids, as well as environmental factors. While certain regions have better disease management, even a 10% loss can have a significant impact on a farmer’s yield and revenue.

One of the main causes of crop loss is pathogens, which are “disease-causing agents” that disturb a plant’s structure, function, or economic value. Pathogens can be especially challenging to manage in traditional farming, but indoor growing methods provide more control over the environment and make it easier to detect and prevent pathogen problems early on.

Proactivity is key to preventing crop loss due to pathogens. One important consideration is the host specificity of the pathogen, as some pathogens are specialists that only infect a certain host, while others are generalists that can thrive in a wide variety of conditions.

Viruses and viroids are two types of pathogens that can cause significant damage to crops. Viruses are cell hackers that stow away in a plant’s cells and use their machinery to reproduce, while viroids are simpler pathogens that are just short pieces of RNA without a protein coat. Both viruses and viroids need a living vector to move from one plant to another and require a wound or opening to enter a plant.

Bacteria and phytoplasmas are other types of pathogens that can cause damage to crops. Bacteria are single-celled organisms that reproduce by cloning, while phytoplasmas are bacteria without a cell wall. Both types of pathogens can be spread by vectors or splashing water, making it important to reduce these potential pathways of infection.

Overall, understanding the basics of pathogens and how they can impact crops is crucial for farmers looking to prevent crop loss and protect their yield. By focusing on proactivity, host specificity, and reducing vectors and pathways of infection, farmers can take steps to protect their crops and ensure a healthy harvest.
