Pythium in soil

It is a type of fungus that proliferates in indoor crops, greenhouses and seedbed. Pythium can be eliminated and prevented using appropriate fungicides for it. But be careful, because if not removed in time, it can cause death of the plant.

A lot of fungi that can ruin our culture marihuna. One of these is called Pythium, actually this species of fungus has several kinds of varieties. Pythium often appears in greenhouses, nurseries and indoor growing, so we have to be very careful if we have any of these types of crops also once has produced its appearance, it acts very quickly. They can also be contaminated with this fungus, irrigation water and even mosquitoes or flies. This species, like many others, can be up and survive for many years in the contaminated soil.

Causes of the appearance of Pythium

They can be a breeding ground for the emergence of such fungi the following conditions:

– A soil temperature too high.
– Areas of cultivation with high moisture.
No extreme hygiene in the growing area.
A substrate is not maintained clean and airy, it can also cause the spread of this fungus.
Over watering the plant. They do not have to be after the usual irrigation pools of water on the substrate of the plant.

Once the plant has this kind of fungus, its devastador effects are felt first in the roots, the fungus makes it virtually impossible nutrient absorption, and rots the plant. Root expands throughout the culture, first by the stem and then leaves, that are seeing increasingly wilted day until eventually die. The fungus can stretch up to even 10 centimeters above the base of the plant.

One must know how to recognize when a plantation is affected by Pythium. If the fungus has affected the seeds, they appear soft, black in color until they eventually die. The plants will go on seeing more wilted day with a yellowish color and can even die.

Prevention

Almost all prevention goes, first, to maintain a clean and appropriate higiene throughout the area of cultivation of cannabis. All the tools that we will use (including our hands) must be very clean and, in the case of the vessels, properly sterilized. Also have to keep the substrate clean and ventilated at all times, as the air flowing around the cultivation of cannabis, and keep each floor, a distance of the other, so that good air circulation between them. Also, the crop should be at a warm temperature, since excessive heat causes this type of fungus proliferate. If the temperature exceeds 30 degrees, and the humidity is above 80%, the fungus may appear because these conditions are its natural habitat.

Change often the mother plant

Another way to prevent the attack of this fungus, is to renew the mother plant after a while, as they may be carrying spores of Pythium, and therefore the cuttings will also be carriers of the fungus. Therefore it is usually advised to use the mother plant, once or twice and then replace it with one of the new plants, cuttings made. Thus, young, healthy, strong, vigorous and without diseases mothers are obtained.

Mix bicarbonate and water, and spray

On the other hand, if we do not want the appearance of this fungus occurs, we must maintain the pH of plant the lowest as possible, always have, of course, the needs of the crop.

Finally, there are some growers who use the remedies called “home” to eliminate fungus harvest. The best – known trick is the use of sodium bicarbonate, remedy that might work, if the fungus does not take more than 3 days in our harvest. The idea is to mix baking soda and water, and sprinkle with this mixture throughout the plant. Baking kills fungi, because it alters the pH of the foliage, but does not harm the plant.

So, you know, watch very carefully to your beloved marijuana plant, and be sure that the substrate, stem, leaves and buds look radiant look and are free from any type of fungus and parasite.
