This is a very interesting research article that covers the different pathogens affecting both the root and shoot growth of Cannabis sativa L. Inoculation experiments were conducted on developing buds and the roots of Cannabis sativa to determine the extent of disease development caused by pathogenic fungi. LINK BELOW
As more propositions pass, tax dollars accumulate, and growers slowly creep out of the woodwork, it’s becoming clear that the CA cannabis industry is entering into a new phase.
While regulators scratch their heads trying to figure out how to best approach this topic, it’s clear that “business as usual” may turn into “business unusual.” Many farmers groan as engineering fees, soil tests, and permitting costs raise the price of going “legal”, but some growers and professionals are nodding their heads in approval. What some view as bureaucracy, others see as a opportunity to ‘do things right.’ CA is the leader in agriculture in the US. We grow the food that feeds most of the country using Billions of gallons of water, mixed with countless chemicals. Is the cannabis industry going to follow the same path? Or are we going to create sustainable and resilient systems promoting renewable energy, zero pesticides and water sovereignty? I’d like to think the latter.
The CHA is happy to provide a spotlight on Grass Roots Grow Mats. They’re made from Hemp, which has been cultivated for fiber and food for over 10,000 years around the globe. The beautiful thing about Hemp is that it helps our planet and people throughout its entire life-cycle and then some!
Grass Roots Grow Mats are now making hemp fiber grow plugs. The CHA will be running experiments with them over the winter to determine the optimal parameters. Check out Grass Roots Grow Mats at: http://grassrootsgrowmats.com
I am sure you’ve heard the old saying about how one bad apple spoils the bunch? Well it’s true, and of all things it’s due to a hormonal imbalance. Who’da thunk? So it turns out that in nature, the first ripe apple of the season drops to the ground and begins to decompose. During the decomposition process, the apple releases a gas called Ethylene. Ethylene is a Plant Growth Hormone (PGH) that triggers the nearby apples to fall to the ground and start the decomposition process. The sweet smell of all those decomposing apples attracts foraging animals who eat the apples and spread the seeds far and wide, often with a little fertilizer to boot (or conversely, to overwhelm scavengers so that some seeds are left undisturbed and able to safely germinate). Ethylene and other Plant Growth Hormones are vitally important to all aspects of plant growth and development, understanding them and their uses can improve any gardener’s yield.
Here is a wonderful article [offline as of 1/19/2020] to become familiarized with certain techniques and practices associated with Integrated Pest Management (IPM).
Moriah LaChapell joined Evergreen Growers Supply during 2015 as an Agronomist. She has a Bachelor of Science Degree in Biology from Western Oregon University and a Professional Viticulture Certificate from Washington State University. She was previously employed at Fisher Farms as the Plant Health Manager. Most of her work at Fisher Farms involved scouting ornamental plants and releasing beneficial insects to reduce insecticide applications. She is passionate about collaborating with growers to produce long term solutions for pests and plant pathogens. You can contact her directly through her website.
Fall is here and so are the caterpillars, at least in Northern California. We have documented numerous instances of caterpillar damage and can officially say there has been a decent hatch this year.
But how to deal with these nefarious little buggers? The best physical control is to carefully groom each plant and hand pick the caterpillars off. They can be difficult to see, but there are key telltale signs of their presence:
Based on our qualitative observations of farms using select products from this line of fertilizers, it is in our opinion that businesses, farms and co-ops, seeking to follow organic input standards, look into using this line of fertilizers.
California Organic Fertilizers has consistently proven their line of nutrients and any single product can make a great addition to a current regime. We recommend that farms and individuals contact their local horticultural center and request this line be carried.
FPJ is used in solutions for seed and soil treatments and plant nutrition. It consists of the young shoots of vigorously growing plants that are allowed to ferment for approximately 7 days with the aid of brown sugar. The brown sugar draws the juices out of the plant material via osmosis and also serves as a food source for the microbes carrying out the fermentation process. “
-University of Hawaii
The general overarching concept is the bacteria in the fermentation process use the sugars to breakdown the plant matter and convert it into a highly available solution of nutrients, hormones, enzymes, amino acids and microbes.
“Maybe it’s because of their wine-making heritage, but the French are obsessed with fermenting various plants into special insecticidal, bactericidal, and fungicidal brews to use on…other plants.”
In a world gone mad with pesticides and fungicides, it’s time we take a step backwards and analyze what our ancestors have accomplished without the use of synthetically created chemicals. This synopsis from frenchgardening.com provides a clear example of different varieties of herbs and their unique control properties on pests or pathogens.
