How do you control crazy roots?

Crazy roots, or excessive root growth, is caused by the Agrobacterium rhizogenes bacterium and is found in tomato, cucumber, eggplant and zucchini crops. This single-celled bacterium disrupts the endocrine system of the plant, causing the roots of the infected plant to grow excessively. Crazy roots can spread quickly. Therefore, it is important to know how to prevent and combat this problem as much as possible.

Identification of crazy roots

Crazy roots can be recognized by the growth of fine roots on the propagation blocks and around drippers. The propagation blocks – and sometimes the substrate mats – become so full of roots that the dripper water drains away. As a result, the plants dry out. Sometimes blocks and mats also become extremely expanded. Furthermore, you can see that the plant is more vegetative, that the stems thicken and that fruit budding and formation are negatively affected.

Crazy roots prevention

In order to prevent crazy roots as much as possible, the following actions can be taken:
  • Avoid using surface water. This is where the crazy roots bacteria may be present.
  • When growing in open soil, make sure that no soil particles from outside the farm end up in the greenhouse.
  • Disinfect the recirculation water. This prevents the bacteria from spreading throughout all of the greenhouse via the dripper system in the event of a possible infection. 
  • Ensure good water quality and use products that keep the dripper system clean, such as Huwa-San. 
  • Avoid root contact between plants as much as possible and do not allow roots to grow in drain gutters.  

Crazy roots control

By injecting Argentum into the substrates of the infected plants, normal root growth is promoted. Healthy, vital new roots that can't get infected can then grow again. During cultivation, ECA and Huwa-San are the solutions for suppressing the Agrabacterium (crazy roots). Furthermore, make sure that you completely clean and disinfect the greenhouse during crop changes to make sure that you deactivate the bacteria and prevent re-contamination. In consultation, our disinfection specialists can provide comprehensive advice on your approach to this.

How to clean clogged drippers
Drippers are very sensitive to pollution. Pollution in the drippers causes water flow differences, which has a negative effect on the quality of the crop. Therefore, it is important to clean clogged drippers as quickly as possible to prevent production losses.
What types of drippers are available?
A dripper is a capillary hose that doses water to the plant. In general, three kinds of drippers are capillary drippers, labyrinth drippers, and pressure-compensated. The best choice for a dripper depends on bed length and water flow.
How to create drainage holes in the substrate mats?
The number of drainage holes and the position of these holes have a major impact on the crop. This is because these are in part decisive for the water flow in the substrate, the re-saturation capacity and the displacement of old nutrient solutions.
