Close damping usually refers to the sudden death of cannabis plants in the seedling stage, due to fungal attack. These fungi are soil borne and are stimulated to grow and infect the seed or seedlings for nutrients released from a germinating seed. However, seedlings can be injured or killed by something other than fungi, for example, toxic materials in soil, soil moisture excess defects or shortages of seeds, extreme temperatures, toxic gases in the air, etc.
A Correct diagnosis is the key to effective control measures. disease, seedling blight is widely distributed and is a worldwide problem. Occurs in most soils, temperate and tropical climates and in greenhouses. The disease affects seeds and seedlings of different cultures. The amount of damage the disease causes seedling depends on soil moisture, humidity and temperature. Normally, however, cool wet soils favor the development of the disease.
Seedlings in nurseries are often completely destroyed by the nursery, or die after transplantation. Often, the seeds germinate die from damping-off fungi before they emerge, which explains the poor are found in many cultures. Older plants are seldom killed by damping-off fungi, mainly because the development of secondary stem tissue forms a protective barrier and limits the penetration of fungi.
However, lots of roots and stems may still be attacked, resulting in poor growth and lower production. When the seeds are planted in soil infested nursery fungi may attack at any time. Damping-off fungi may attack the seed before germination, or they may attack after the seed has germinated, but before the plants emerged above ground level. Infected seed becomes soft and mushy brown to black, and finally disintegrates. The seeds that have germinated and are infected develop watery spots that enlarge and turn brown.
Solution: The appropriate conditions for cannabis seed germination and seedling emergence also favor vigorous growth of fungi that cause damping-off. The seeds and roots are kept moist and warm until the roots have penetrated the soil and the plants grew. As the plants grow, the moisture in the earth’s surface can be reduced, and damping off fungi then, is less useful. When watering thoroughly saturate the soil and then apply more water until the country is approaching the point at which plants wilt. This procedure is to keep the soil surface to dry a lot of time. Pasteurization of soil is the best way to protect themselves. Land for cultivation of apartments transplantation can be steam pasteurized. If steam is used, the whole country, the mass must be maintained at a temperature of 160 degrees for 30 minutes. Home gardening is certainly not the steam of the soil, but packaged pasteurized soil mix is available in many garden stores.
To prevent recontamination of the soil, all the items as tools, pots and flats, etc., must be clean. Items can be washed in hot water (160 degrees for 30 minutes) or bleach solution (1 part bleach to 9 parts water, soak for 30 minutes). It is important to use fresh bleach solutions.
Cannabis seeds must also be of high quality for better growth and germination.Dutch Seeds provide you that better quality on affordable prices.
