So you are aware there is a problem that may effect you in the future.

Fusarium from what I can make out it has been devastating both commercial growrooms and the home grower in Holland for several years now and they have been loosing the battle.

What is fusarium? This is nicked from an agriculture research site.
----------------
Taxonomy: Vascular wilt fungus; Ascomycete although sexual stage is yet to be found. The most closely related teleomorphic group, Gibberella, is classified within the Pyrenomycetes.

Host range: Very broad at the species level. More than 120 different formae speciales have been identified based on specificity to host species belonging to a wide range of plant families.

Disease symptoms: Initial symptoms of vascular wilt include vein clearing and leaf epinasty, followed by stunting, yellowing of the lower leafs, progressive wilting of leaves and stem, defoliation and finally death of the plant. In cross-sections of the stem, a brown ring is sometimes evident in the area of the vascular bundles. Some formae speciales are not primarily vascular pathogens but cause foot and rootrot or bulbrot.

Economic importance: Causes severe losses on most vegetables and flowers, several field crops such as cotton and tobacco, plantation crops such as banana, plantain, coffee and sugarcane, and a few shade trees.

Disease control: Use of resistant varieties is the only practical measure for controlling the disease in the field.

Under greenhouse conditions, soil sterilization can be performed. Alternative control methods with potential for the future include soil solarization and biological control with antagonistic bacteria or fungi.

General back ground info, in the resent past both the USA and Russia have been putting millions a year to develop new strains of fusarium oxysporum as biological weapons to spray on enemies crops. The USA are still working on it and have also been trying to develop a form of fusarium specific to cannabis, the idea being to eradicate the entire genus from the planet or at least parts of it.

Things that can reduce the risk of infecting your plants. It is obvious that a large proportion of imported bud from Europe is from infected plants. Just touching bud and then touching a plant can infect the plant, smoking a joint of infected bud anywhere near cannabis plants can infect them. It can be carried in infected clones.

It is also now here in grow rooms in the uk, it is going to spread. You have been warned.
