Irrigation lines are quite literally a lifeline in any agricultural or landscaping system. Delivering water and nutrients directly to crops, grass or other plants, a healthy irrigation system is essential for maintaining productive growth and reliable yields. However, these systems can also fall victim to harmful bacteria. Unfortunately, due to the very nature of irrigation systems and their dark, damp interior environments, they are a haven for bacteria and can quickly become a breeding ground for biofilm. <\/p>\n\n\n\n

This sticky, film-like slime adheres to surfaces over time and is built from layer upon layer, resulting in a \u2018megacity\u2019 of breeding bacteria that reduces water flow and harbors plant pathogens. A serious threat to growers of any capacity, biofilm can even pose a risk to food safety. It is also notoriously hard to remove, as the bacterial matrix that forms it is highly resistant to traditional cleaning methods and many chemical treatments – but all is not lost. <\/p>\n\n\n\n

In this article, we\u2019ll explain what biofilm is, how it develops in your irrigation water, the risks it poses to plant health and productivity, and why flushing alone isn\u2019t enough to eliminate it. We\u2019ll also explore effective maintenance schedules, highlighting what biofilm treatment products to choose, and how to prevent any future bacterial growth. <\/p>\n\n\n\n

What Are Irrigation Lines?\u00a0<\/strong><\/h2>\n\n\n\n

Irrigation lines are the tubes that carry water from a water source to crops grown for agricultural purposes. They are also an essential element of landscaping, keeping spaces such as golf courses green and healthy. However, the dark and moist environments of water systems make them a breeding ground for bacteria. When certain types of bacteria accumulate, it can lead to a film-like coating within the pipes, reservoirs and tanks known as biofilm. Eventually, this can lead to clogging and reduced water flow, which can pose a serious threat to the health of your plants or crops. <\/p>\n\n\n\n

What is Biofilm and How Does It Occur? <\/strong><\/h2>\n\n\n\n

Biofilm is a slimy coating found on most surfaces that are in frequent contact with water. Within the film is a highly organized, rampant and resilient structure of bacteria (often called a \u2018matrix\u2019) able to host a wide variety of microorganisms. The formation of biofilm can be broken down into the following 5 steps: <\/p>\n\n\n\n

Attachment <\/strong><\/h3>\n\n\n\n

Free-floating bacteria (also known as planktonic cells) that travel through the supply of water attach themselves to the inside of the lines. <\/p>\n\n\n\n

Adhesion & EPS Production <\/strong><\/h3>\n\n\n\n

Adhesion is enhanced by the production of EPS, a complex mixture of polysaccharides, proteins, and lipids, which forms a matrix surrounding the cells.<\/p>\n\n\n\n

Growth<\/strong><\/h3>\n\n\n\n

The microbes in the biofilm proliferate, and the biofilm becomes thicker and harder to remove. Over time, the matrix will continue to grow and mature into a complex 3D structure.  <\/p>\n\n\n\n

Dispersal <\/strong><\/h3>\n\n\n\n

In some cases, cells will break off from the mature colonies, returning to the \u2018free-floating\u2019 state above. <\/p>\n\n\n\n

Further Colonization<\/strong><\/h3>\n\n\n\n

Those broken-off cells will repeat the process elsewhere in the irrigation line, becoming adhered to the surface and developing into a complex, sticky structure.  <\/p>\n\n\n\n

The Problems Caused by Biofilm in Irrigation Systems<\/strong><\/h2>\n\n\n\n

As a grower, your priority will of course be ensuring a maximum yield of the highest quality. By understanding the risks posed by the development of biofilm, you\u2019ll be better informed on how to properly maintain your irrigation lines. Below, we\u2019ve listed the biggest dangers of biofilm:<\/p>\n\n\n\n
