Cannabis Growers Alert: Fusarium and How to Treat It - Article 2 in a 4-Part Series
The legal cannabis industry in North America is the hardest hit by Fusarium because licensed growers must have their product tested for fungus and a wide variety of other contaminants before it goes to market. When Fusarium Oxysporum and Pythium spores enter a farmer’s irrigation system these microscopic spores are virtually invisible and are impossible to detect. By the time they have infested the roots of an entire crop, the symptoms of mass plant wilting leave no time for correction or remediation with conventional measures. By the time a farmer spots mass wilting of the crop, it’s too late and the crop is ruined. This situation can become a nightmare for even the most experienced, educated agricultural specialists when all the soil used by the farm becomes contaminated as well.
In our uncultivated “wild” soils, Fusarium behaves just like most wild fungus and mushroom species and is harmless and even beneficial to some plants. But when exposed to artificially man-made conditions of large-scale agriculture, either out in the open fields or in the greenhouse and indoor facilities, Fusarium runs rampant, morphing into a lethal monster for crops. Scientists studying this species and its similar behaving Pythium relative, have already determined that they thrive in controlled agricultural environments precisely for the same reasons crops do.
Many large-scale commercial marijuana operations have recently experienced a sudden proliferation of Fusarium Oxysporum and Pythium infestation due to the ideal conditions these marijuana cultivators strive for. But instead of co-existing unobtrusively with plants as they do in the wild, they take over and can easily overrun and wipe out entire crops if left unchecked. Specifically, the growth cycle for marijuana is so relatively short compared to other cash crops, Fusarium doesn’t necessarily have enough time to completely destroy the plant but has just enough time to infect the precious marijuana buds.
This is article 2 in our 4-part series on Fusarium and How to Treat It. If Fusarium is affecting your cannabis crops, or other crops, we may be able to help.
In less than two months of using water made from Watson’s Ozone Water Treatment System, we are watering our farm with clear pure treated water which actually contains over 300% more dissolved oxygen to all the plants roots. The difference it is made with our crops this year is incredible.
Don Watson and his family have been providing experienced and reliable service to our well-water system since 2011. In those seven years, Watson Well has made a number of timely emergency service calls at any time of day and night, upgraded our water system, and rehabilitated our well.
When our well stopped producing water this summer, I called Watson Well. They used a special pump and opened up the well from 67’ to 132’. While inspecting the well with a video camera, they found that the wells steel casing had deteriorated in a number of places leaving large holes where sand and gravel were continuing to enter the well. They immediately installed a new liner and gravel packed the well. Our well has never produced this much water volume in twenty years of living on this property. We are also noticing a tremendous improvement in the quality of the water.
As Public Works Director for the Bear River Band of the Rohnerville Rancheria, I have contracted with Watson Well on five different projects for the tribe, here in Loleta, CA. Their company has completely replaced both of our main water systems submersible pumps and piping, which was not an easy task, as those wells are very deep. These projects were done very quickly and efficiently, while still maintaining a potable water supply to everyone at all times. They have the tools and equipment to not only handle the small jobs, but large jobs like this also. They have also installed three water softening units for us, as our water is very hard. These are big commercial units and all are working flawlessly. They have also developed a small rural water system for us on a piece of property the tribe recently purchased, to supply water to livestock. All of the work they have done for us is doing what they said it would do, without any problems or issues. Don, his sons, and employees are all very knowledgeable and professional and did our projects at a very reasonable cost. They stand behind their work and are only a phone call away. I would highly recommend Watson Well for any water project, no matter what the size, if you want it done right, on time and on budget, you won’t be disappointed.
It is hard to believe that it has been 9 months since I called you with an “out of water” problem on our property. It is not the call that any one on a well wants to make during a record breaking drought. You were here in a very short time and after taking in all the normal diagnostics you were concerned about us being dry but not convinced it was a true dry well. I think we were very fortunate that you had the ability to put a camera down our well to see what was happening and came up with a plan to rehabilitate our well after you discovered our weep holes for the well were plugged with iron bacteria, calcium and stuff. It gave us hope that we could get this reliable well up and running. You pulled the pump and line and determined that pump was fine. Once that was clear you put in the proper chemicals and literally scrubbed our well pipe of the “stuff” and found that our well was over 200’ deep. Water flowed and once the junk was sucked out of the well bottom and the chemicals neutralized we had 18’ more water which put us at over a 50’ column of water, of course this was fantastic. While here, all new water line and electrical wire was reinstalled and new electronics that were more current and a vast improvement of what we had. Since then the water keeps flowing with generous amounts and quality.
During the past two years, Watson Well has designed, constructed, and maintained a number of different projects at my home. These include new water storage tanks, a water treatment system, new piping from the pump house to the residence along with separate lines and faucets for untreated water; and a complex rain water catchment system including tanks, piping and faucets to different locations, all while providing flexibility directing the water to different areas as needed. Don Watson and his crew worked efficiently and coordinated the different aspects of the jobs in an effective manner. All systems continue to operate as expected without any problems. Don was always extremely helpful and receptive to new ideas which he easily incorporated into the projects.
