It’s common to encounter pests and diseases such as verticillium wilt on cannabis during weed cultivation. While creating an ideal grow environment may minimize problems, there’s no one-size-fits-all solution to these ailments.
Some fungal infections, like verticillium wilt, are trickier to deal with because they strike your crops unexpectedly. The damaging outcome may escalate from withering your plant to causing eventual death, but it’s not impossible to counter.
Another challenge is noting the symptoms, as this disease closely resembles other marijuana maladies. Understanding what to look for and how to prevent it is your best defense against fatal heartbreak.
Keep scrolling to see how you can confront verticillium wilt on cannabis and save your favorite plant from sudden demise.
What is verticillium wilt?
Verticillium wilt is a soilborne plant disease originating from fungus presence.
It often targets stressed marijuana crops or those grown in overly nutrient-rich soil or with poor drainage. Humid areas with a temperature around 68-82?F create the ideal conditions for this pathogen.
The definition of verticillium wilt in cannabis plants is similar to fusarium on weed. The difference is that the former is prevalent in cool weather, whereas the latter is more common in warmer climates. They both also originate from distinct fungal species.
Once it strikes, the fungus affects the roots before traveling up the vascular system to other plant parts. The xylem, which transports water and nutrients from the base to the stalks and leaves, facilitates the spread of the disease.
As verticillium wilt grows, it discharges toxins while creating a blockage inside the xylem. This clog deprives your crops of water and the right nutrients to thrive. The contamination spreads throughout the plant, causing it to yellow, wilt, and ultimately die.
This fungus can sit in the soil for many years, turning the area unfit for cultivation. Whenever you buy nutrients for cannabis, ensure you don’t overfeed your crops. Keep a keen eye on your soil’s drainage to avoid this potentially destructive infestation.
The signs and symptoms of verticillium wilt on cannabis
Learning how to stop verticillium wilt depends on whether you can identify the signs and how soon you catch it.
It’s not unusual for growers to confuse this fungus with a nutrient deficiency or a thirst problem. Noting the specific symptoms of verticillium wilt is the best way to tackle it and implement accurate preventative measures.
The telltale signs of a verticillium fungus often show on the leaves or the entire plant. Closely monitor and pay attention to any changes in your crops’ appearance and growth to protect them from infection.
Your plant’s leaves, especially those close to the base, may depict distinct color changes as follows:
After overwhelming the leaves, the fungus may increase the damage to other plant sections and cause:
How to get rid of verticillium wilt
Understanding how to get rid of verticillium wilt on cannabis is essential in rescuing your unaffected crop. There’s currently no effective treatment for infected weed. Eliminating the contamination entails separating sick plants from healthy ones.
Once you’re sure the fungus has invaded your crop, it’s vital to take immediate action. Remove the affected vegetation promptly but carefully, extracting as much of the root system as possible.
Be cautious not to spread the soil into the vicinity, as you risk a recurring outbreak in other portions of your crop. The fungus can also move through the air via spores.
Don’t put another weed plant in the same compromised soil, as it won’t mitigate the spread of verticillium wilt. Prepare a fresh potting mix and begin a new transplant instead. Thoroughly sanitize your pots and tools to avoid another fungus problem.
How to prevent verticillium wilt
While you may not treat verticillium wilt the same way as cannabis pests, prevention is possible. There are several practical approaches you can implement to avert severe crop damage.
The best option is to switch to a hydroponic setup. This technique is useful if your garden is massively contaminated or the soil is no longer reliable. It gives you better control of your crop when adding nutrients and makes it easier to spot diseases and pests.
Choose the best soil for cannabis growing if you want to cultivate marijuana the old-fashioned way. Amending your potting mix with sterilized or properly aged compost is the healthiest alternative and provides your seedlings with a nutrient-rich foundation.
Verticillium wilt tends to hang around the roots. Since this fungus thrives in humid conditions, adequate drainage may help keep your soil clear of it. Add more organic matter to improve liquid flow, or use a raised garden bed for seamless runoff when watering outdoor weed.
Soil solarization is another eco-friendly preventative solution. Sterilizing your compost in the sun helps you repel infestations without hazardous fumigation.
This non-chemical method involves plowing the land, blending the compost, and adding water before applying a transparent plastic cover. Exposing the soil to radiant energy for up to three weeks destroys microorganisms such as fungi, bacteria, insects, mites, and nematodes.
Practicing crop rotation or deep plowing before transplanting your seedlings may also help prevent verticillium wilt. Plant a fungi-resistant specimen such as sudangrass, broccoli, or mustard if the soil is already infected. Then, solarize the earth to strip it of harmful microbes.
Preventing a fungus infection is better than searching for a cure, and starting your cultivation on the right foot is imperative. Finding proven weed seeds for beginners is one way to guarantee resilient plant growth.
Who said wilting has to be a death sentence?
Prevention is the only way to deal with verticillium wilt on cannabis. There’s no established way of controlling the pathogen or healing the affected plants once it takes over your crop.
This fungus can live in the soil for years and could be a stumbling block in your cultivation efforts. To avoid this setback, implement proven solutions such as soil solarization, proper drainage, sufficiently aged compost, and hydroponic setups.
If you catch the infection too late, remove the affected crops to curb the outbreak. Better still, equip your weed plants with solid genetics from the onset to make them less vulnerable to pests and diseases.
