What to Do When Powdery Mildew is in Buds Before Harvest

It is harvest time, and you notice powdery mildew on your cannabis buds before harvest. What do you do? This is a question that many growers face, and the answer can be tricky. This blog post will discuss what powdery mildew is, how it affects cannabis plants, and what you can do to prevent it from ruining your harvest. We will also provide some tips for dealing with powdery mildew if it does appear on your buds before harvest.

What is Powdery Mildew

Powdery mildew is a type of fungi that affects many plants, including cannabis. Powdery mildew appears as white or gray powdery patches on the leaves of affected plants.

Why Powdery Mildew Is Dangerous In Buds Before Harvest

The powdery mildew fungus can spread quickly and easily from plant to plant, and it thrives in warm, humid conditions. When powdery mildew appears on cannabis plants, it can cause the leaves to turn yellow or brown and eventually die. The buds of affected plants may also be covered in powdery mildew, reducing their quality and yield. Carefully cut out the infected leaves and buds and keep them away from the room and dispose it as soon as possible.

Preventing Powdery Mildew

The best way to deal with powdery mildew is to prevent it from appearing in the first place. There are a few things you can do to reduce the risk of powdery mildew appearing on your cannabis plants:

  • Water early in the day so that the leaves have time to dry before nightfall
  • Provide good air circulation around your plants
  • Avoid overhead watering
  • Clean up any dead leaves or plant debris around your grow area
  • Inspect your plants regularly for powdery mildew and other pests or diseases
  • Add an AirROS surface & Air Purification system

If you find powdery mildew on your plants, it is essential to take action immediately. The sooner you remove affected leaves and buds; the powdery mildew will cause minor damage.

Prevent Powdery Mildew From Spreading In Buds Before Harvest

A great way to prevent powdery mildew from cross-contamination is installing AirROS commercial air and surface purification system and having proper airflow in the cannabis grow rooms. An AirROS system installed can dramatically, if not stop the spread of powdery mildew in buds before harvest. As a result, this will increase yields and revenue $$

How does an AirROS commercial air purification system work?

AirROS is a commercial air and surface purification system that can prevent pathogens, mold, viruses, yeast, and bacteria, reduce cross-contamination, and eliminate cannabis odor. AirROS purifiers utilize and create ROS (Reactive Oxygen Species). First, it kills pathogens and aroma / odor as it passes through the air purifier. In addition, it sanitizes the air that comes out of the purifier, enters the environment, and continues to sanitize all surfaces it contacts. Here is the 2 stage process:

Phase 1- Primary Air Cleaning

Placed within your room’s airflow, air from the environment containing microorganisms enters the purifier’s internal chamber. The reaction chamber creates non-thermal plasma and generates ROS. ROS are comprised of 5 short-lived, highly Reactive Oxygen Species:

  • Atomic oxygen O(3P)
  • Singlet oxygen 1O2
  • Hydroxyl radical .OH
  • Superoxide O2-
  • Peroxynitrite ONOO-

These break down carbon-to-carbon bonds that sanitize the air and destroy all bacteria, molds, viruses, and other pathogens as they pass through the reaction chamber.

Phase 2- Secondary Surface & Air Cleaning

Provides Surface sanitation and continued Air sanitation. The purified air now diffused into the environment contains longer lived Reactive Oxygen Species:

  • Gas-phased H2O2 (GpHP) or dry hydrogen peroxide
  • Low concentration levels of O3 ozone

These combine and create Hydrogen Trioxide (H2O3) an Active Antimicrobial formed through the peroxone process. This H2O3 is very effective at sanitizing the surfaces and air 24/7.

ROS with H2O3 further sanitizes the room air and long-distance surfaces from the purifier. This commercial air purifier technology is the only one that can provide odor control, long-distance surface treatment, and purify the air all at once. Amazing right? To learn more, watch this video below!

AirROS commercial air purifiers are essential for ensuring a safe and clean cannabis cultivation facility and cannabis buds.
