Daktilium (arachnoid mold, powdery mildew) Dactylium dendroides
Pathogen Daktiliuma molds Dactylium dendroides
The fungus forms a coating on the surface of the soil is grayish-white or pinkish-white patches of fluffy cobwebby mycelium that growing, goes on fruit mushroom body. They stop growing, their tissue darkens and becomes watery rot. mold development is very fast, the same should be quick and reaction mushroom grower, its removal and control of proliferation. Symptoms of the disease appear in the latest wave of fruiting mushrooms if there was infection with spores. In case the covering mixture mycelial fragments infected pathogen, the disease is detected at the first wave of fruiting. Cobweb mold is very easy because spreads quickly ventilated, dirty packaging, personnel working tools and equipment, insects, nematodes and rodents. There were cases when the cooling stage (SHOCK) already manifested Ductil foci. The reason turned out to be a great background of this pathogen in the entire enterprise. Daktilium very dangerous and insidious mold and can bring the enterprise to a full stop.
Until such a catastrophic spread of mold to allow strictly prohibited.
The reasons for the development of mold:
Failure to comply with sanitary norms and rules. High humidity and temperatures above 18 ° C. Under these conditions Daktilium spontaneously expands its area and is capable of infecting many very quickly mushroom fruit body. The reason for moisture, may be:
- Very small exhaust passages (Hall has to “breathe”)
- Presence of insects and nematodes
- The presence of patients mushrooms and waste on the premises
- Increasing resistance to fungicides. Remedies should be changed periodically
Watering shelves to the elimination of the lesions and infected fruit bodies, it contributes to the rapid spread of Dactyl. Watering is an important growing process, when making water drops on the surface of the beds can also spread spores and mycelia Daktiliuma.
Often the disease begins:
- with the left leg on the shelves of mushrooms after harvesting. Therefore, the first health unit cleans the shelves from the broken, fallen legs and mushrooms, and only then removes all diseases
- no filters in the channels of the fresh air supply and exhaust windows
- the use of non-quality coating mixture.
Prevention and control:
- Continuous monitoring of indoor cultivation conditions and climate factors, especially humidity
- Use of the coating mixture reliable suppliers
- When watering Pokrovka need to use protective equipment Shirlan or banjo. If you are using keking, on the second day, without kekinga 3-4 day entered one of the fungicides. The dosage is the same for both: (. 20-30mll 100 l.), 1 liter of solution per 1 m². If the threat of mildew infection is high, then as a preventive, it is possible at the end of the first and second waves after the irrigation water, to make any of the fungicide with the dosage – 10-15mll. 100 l. water
- Get rid of the insects and to control their presence
- Immediate discharge from the premises all waste and disease
- Net disposable overalls and caps are mandatory for all staff
- It is very important good lighting shelves
- The floors in the corridors and halls of cultivation must be kept clean and moist
Moving the collectors for the production should be strictly regulated, always start picking mushrooms need a cleaner finish and growing rooms more infected persons. When collecting the fungus must be very careful, small pockets of mold is not always seen by the fungus. If it really happened that struck the mushroom forager saw already in hand to gently put it on the place where he grew up. Remove the inverted glove and put in place the mold chamber (in any case, do not throw in a bucket of spines affected fungus and gloves). Dirty knife wrapped in a plastic bag and send it to the sink. Gathering continue to clean the knife in the new gloves, leaving the mushrooms over a larger area than the visible mold itself hearth. Avoid contact with infected mushrooms in a box. Suffice couple of diseased mushrooms in a box, so they very quickly infected all the mushrooms in it.
Avoid mold infection to large hearths and remove even small, as large centers will be difficult to handle. Remove Daktilium pickers do not (they are then at risk of becoming a source of further infection), and specially trained employees “health team” that is desirable to the collection and after collection should carefully review and clean up all the shelves. Pickers in turn, should be easy to identify the mold – in the first place, so as not to touch himself and focus to the fungal infection, and secondly, to notify the foreman about her presence. It is advisable to hang in domestic premises posters with information about the disease.
If there is no health care, it is desirable to collect and then mushroom gathering is necessary to allocate a few trained pickers to remove pockets of mold. After this operation, all the clothes must be washed in hot water and a maximum disinfected.
Remove lesions and affected mushrooms Daktiliumom to be very careful. In order to do it safely, we recommend the following technique. Disposable plastic bag is worn on special accommodate made of plastic pipes (the diameter of 150 mm.), And then adapt this hotbed of Dactyl, together with mushrooms “pulled” to the compost. The package is tied and in a special container or large plastic bags all taken out and disposed of. Thus, the outer side of the package remains clean, no contact with the hand, and the number of spores and mycelia of mold, caught in the air – is minimal.
The place where the mold has been removed, it is best to fill carefully (without hitting the next growing mushrooms) solution SHERLANA or bungee (20 mll. To 10l. Water). For this is well suited for small polivayka vases. Salt is not desirable because when watering it will scatter in different directions and later on mushrooms appear yellow spots. If it really happened, that hotbed of mold larger than the diameter adapt, then it together with mushrooms need abundantly pour a solution of fungicide above described method. After that, the plastic bag larger carefully selected together with mushrooms and Pokrovka.
Minimize the spread Daktiliuma across the enterprise! Before unloading chamber must proparit not less than 12 hours at 68 degrees. After unloading thoroughly cleaned, including klimatustanovki. If the lights are removed before steaming, and then thoroughly washed and disinfected. When there is no possibility of growing steamed Hall: firstly, it can be discharged earlier, when the spread of the disease is not so much, and secondly, it is desirable to process the shelf disinfectant. After unloading, a thorough washing chamber and air conditioning systems, to disinfect. Disinfection is carried out with a solution Virotsida, Disolita or their analogues. There are various special gun (foggers). Virotsida solution in a proportion of 1 liter to 6 liters of water or its analogs. First produced in blowing-deztumanom recirculation channel enabled fan, the fan stops and then processed by the entire room.
The most effective method of preventing secondary spread of all diseases is only steaming! disinfectants processing though and helps reduce the risk, but not very effective.
