What Does Bud Rot Look Like Under a Microscope?
Under a microscope, bud rot can appear as a mass of branching, thread-like hyphae known as mycelium. The mycelium may appear white or gray and may have a cobweb-like appearance. The mycelium can also produce sporangiophores, which are structures that produce and release spores (spores) that can infect other parts of the plant.
How Does Bud Rot Spread
Botrytis fungus initially infects the plant from the inside, but as it grows, it spreads to the outside, making it vulnerable to air currents.
How can Bud Rot Spread
For bud rot to occur, mold needs to make contact with your plants first. It may seem like an unlikely occurrence, but the dusty spores of the mold are quite easily transported, reaching your plants through air, water, and other pollinators, like contamination by farm tools.
Once the spores get to your yield, they form a wound or tear in the external tissue and enter the buds. The Botrytis Cinerea then continues to break down the surrounding bud and spread out to other areas of the plant
How Fast does Bud Rot Spread
Bud rot spreads quickly and dangerously.
The white, wispy sheen (mold) may be seen only for a day or two before it becomes dark brown or gray. Therefore, it is difficult to spot when starting, since you’ll probably never notice this sign before it changes.
Then you see the colas (leaves around, buds and pistils) become dark, dried up, dying.
In less than a week, the bud rot can spread the whole grow room if the conditions becomes conducive, such as high humidity level, poor air ventilation, and stagnant air flow etc.
Can Bud Rot Happen Overnight?
Bud rot can occur relatively quickly, and sometimes, it can happen overnight. This is because the fungus that causes bud rot can overgrow under the right conditions, such as high humidity levels and poor air circulation.
However, it is important to note that the development of bud rot is usually the result of a combination of factors. In some cases, it may take several days or even weeks for the symptoms of bud rot to become apparent.
Where Does Bud Rot Start?
Bud rot typically starts on the buds of the plant. The buds are particularly susceptible to rot and mold because they are tightly packed and often have poor air circulation.
Once the infection has started on the buds, it can spread to the stems and leaves of the plant, causing them to rot and wilt.
Does Bud Rot Spread to Other Plants?
Bud rot can spread to other plants. The fungus that causes bud rot produces fragments that can be dispersed by wind, rain, or other means, infecting other parts of the same plant or other plants. Touching infected parts of the plant can also transfer the fragments to other parts of the plant or other plants, spreading the infection.
Is Bud Rot Harmful to Humans?
Bud rot can be harmful to humans if the infected buds are consumed or inhaled. Inhaling mold or fungal fragments can cause symptoms such as coughing, wheezing, nasal congestion, and difficulty breathing and trigger allergic reactions in some individuals. In severe cases, exposure to mold or fungal fragments can lead to more serious health problems, such as pneumonia or other respiratory infections.
How to Treat Bud Rot
To save a plant with bud rot, it is important to identify and remove all affected buds, cutting back to healthy tissue. If the infection is caught too late or is too severe, it may be difficult or impossible to save the plant.
How to Treat Bud Rot if it was Infected?
If the core is displaying the signs we mentioned above
- Isolate and investigate: isolate by cutting it out and quarantine that area of your grow room. Sample and investigate all other plants nearby to determine if the botrytis cinerea has had time to spread out.
- Remove the affected buds: cut off any affected buds with trimmers and store it in a sealed container to prevent any accidental spreading. Remove any healthy buds that are touching or in close proximity to the affected buds, as the spores can spread easily.
- Consider pruning: if the infection is severe, you may need to prune back the plant to remove all affected parts. This can be a difficult decision, but it may be necessary to save the rest of the plant.
- Dispose and sanitize: dispose of this container and sanitize all gardening equipment used as well as your clothes. Changing your clothes and wearing protective gear when moving from one grow room to the next.
- Thorough assessment: before concluding your bud rot removal, do conduct a thorough assessment of the whole plant to ensure all the affected areas are removed quickly.
- Keep the affected area dry: bud rot thrives in moist conditions, so it's important to keep the affected area as dry as possible. Use a dehumidifier to lower humidity levels if necessary.
- Improve air circulation: good air circulation is important to prevent the growth of mold and mildew. Make sure your grow room is well-ventilated, and use fans to improve airflow.
- Make sure to leave space between hanging branches as your buds dry out or create an optimal environment for the drying process.
- You can even try out various speed-drying techniques to limit the time that your buds spend in conditions that could promote Botrytis cinerea.
The differences in treating bud rot outdoors versus indoors are mainly due to environmental factors and the size of the growing area. Outdoor growers have to deal with the elements and weather conditions, which can make it more difficult to control the humidity and temperature levels in the growing area. Additionally, the larger size of outdoor grow areas can make it more challenging to isolate and treat infected plants, as well as to monitor the spread of the disease.
To treat bud rot outdoors, it is important to follow the same basic steps as when treating it indoors, such as removing infected areas, using fungicides, and providing proper ventilation.
However, outdoor growers may also need to take additional measures to protect their plants from the elements, such as constructing a temporary shelter or installing fans to increase airflow. In addition, outdoor growers may need to use larger quantities of fungicides to treat a larger growing area and to ensure that all parts of the plants are properly covered.
