Powdery mildew, often known as blanquilla, is a fungus that marijuana breeders fear. There are various species that can harm your plants, and if not controlled, they can destroy an entire harvest. Continue reading to learn how to avoid and eliminate powdery mildew from your crop.
What exactly is powdery mildew?
The Oidium, also known as pigweed or vella malura, was the result of several tales, including that it was generated by a steam locomotive or fevers caused by simply passing through a contaminated culture.
The fact is that the term powdery mildew refers to a group of fungi in the Erysiphaceae family that are defined by their ability to operate on plants outside.
An analogy with the lawn can be used to describe how the fungus is implanted in the plant. Each blade is a fungus with its exterior mycelium, and in the area of contact with the plant cell, it contains clamps that allow it to hold on and take the nutrients you require. Unlike Mildew, mycelium develops on the outside of the sheet and on the upper side of powdery mildew.
Powdery mildew on Marijuana can weaken plants, causing infumable buds, impair your marijuana operation, and notably harm the health of those who ingest marijuana contaminated with this oidio.
Powdery mildew identification in marijuana plants:
It should be noted that identification with the naked eye is always aimed at successfully treating the plant in a curative manner, but powdery mildew is present every year, so preventive tasks must always be carried out and left to verify that the Powdery mildew has not appeared and that preventive action has worked.
How to Keep Powdery Mildew at Bay in Marijuana Plants:
- To avoid the formation of powdery mildew during marijuana production, there are a number of extremely effective techniques that, if made a practise of, will keep you from having difficulties with this nasty fungus.
- Cleanliness is essential in greenhouse or outdoor marijuana production, as is the removal of old leaves and cultivation waste. Powdery mildew spores can survive the winter by hiding in dry leaves and spreading spores in the spring when breeding circumstances are suitable.
- Indoor crops require the same level of cleanliness, but it is also critical to change out of your street clothing before entering the crop and thoroughly wash your hands.
- Maintain a humidity level of less than 60% in indoor crops and greenhouses.
- Don’t overdo it with the nitrogen, because powdery mildew reproduces and instals faster in plants with too much nitrogen.
It is critical that your crop has sufficient ventilation and that the plants are separated from one another so that air can flow and no pockets of humidity form.
Before using the pots, thoroughly clean them with bleach and thoroughly rinse them with water. Maintain the cleanliness of the indoor grow’s walls and floors.
Last words
Powdery mildew spores can be carried to your plants by insects. Keep whitefly, aphids, and thrips away from your protected cultivation since they usually wear clistotecios, potassium soap on their feet.
Look for strains of marijuana that are resistant to powdery mildew, such as Jamaican Dream or Critical + 2.0, especially if you have previously been attacked by this fungus.
