Systemic Acquired Resistance: Plants’ Secret Weapon
Triggering Plants’ Immune Response Provides Protection Against Disease
For nearly a century, plant scientists have known that when a plant survives a disease, it often is more resistant to subsequent infections. It’s as if the plant’s immune system has become stronger, and indeed it has.
Because they are rooted in the ground, plants appear to be at the mercy of every disease or insect that comes their way. However, plants actually have a number of defense mechanisms. One of these is systemic acquired resistance (SAR), a whole-plant defensive response to disease. When a pathogen invades, a long-distance chemical signal is sent from the infection site that triggers the SAR response.
While research is still ongoing and many questions remain, it appears that salicylic acid (SA) plays a key role in the long distance signaling, which occurs via the phloem, or nutrient transport system. Scientists believe that infection causes a buildup of SA, which in turn triggers the plant genes specific to the SAR response to produce pathogenesis-related proteins. These proteins, some of which have been proven to have anti-microbial activity, remain within the plant to help protect it from further infection.
It is important to note that not all pathogens elicit the SAR response, and not all plants react in the same way. But it is clear that the SAR response is an important component of plant health. The true potential for agriculture though, lies in developing the ability to elicit this response before the first infection, preventing the initial loss of plants and yield. Plants have been bred for disease resistance for years, and it works, but it’s a process that takes many years. Having the ability to induce a systemic resistance in the current year’s crop by triggering a chemical response within the plant is a powerful tool for growers — one that can be integrated into the crop protection program and may reduce conventional pesticide use.
Chemical elicitors of the SAR response have been discovered. Since the elicitor itself doesn’t have anti-microbial action it has less environmental impact than most conventional pesticides. Studies have been conducted using various elicitors on a number of crops. The efficacy of both the elicitors and the SAR response itself was dependent upon a number of factors including the dose, the plant’s genetics, the frequency of application and the pathogen. In some cases, the SAR response generated was ineffective, but in others it was just as effective as the conventional treatment. In other cases, the response was effective, but the best results were obtained in combination with other crop inputs.
Many KeyPlex products contain proven elicitors that activate the SAR response along with essential micronutrients for plant growth. Combining the nutrients plants need with elicitors that boost the immune system is one way to ensure that crops will grow to their full potential and stay that way.

For decades, the cultivation of marijuana has focused on obtaining the highest production possible, in the fastest and most effective way. For a long time, most marijuana growers thought that to obtain this they had to use chemical fertilizers.
Fortunately, as the cannabis industry evolves and takes shape, this cultivation paradigm also transforms. There are more and more growers who are betting on organic farming, because not only does it produce higher quality crops, it is also healthier for consumption and more environmentally friendly.
They all seem to be advantages! Participate in the wave of organic farming by following some simple steps that we explain below.
A step by step guide on how to make your cultivation of organic marijuana, a simple and very useful method that will increase the quality of your cannabis flowers.
Cultivation of Organic Marijuana – Preparations are paramount.
The advantages of growing marijuana in organic mode compared to growing with chemical fertilizers are many, but we could reduce them to a rule of three: it is better for the plant, it is better for the final consumer of marijuana and is better for the environment
It must be remembered that everything you give to the plant will end up in your body when you will consume the flowers, and certainly you will not want to introduce into your system many chemicals that you do not know how they can affect your health in the long term. Without considering the fact that the taste of marijuana grown with organic products is far better than the sour taste that often stings in the throat, typical of marijuana grown with chemicals.
Although it is not among the most damaging things, it is not good for the environment to leave traces of chemicals in the soil or in the waste water.
Your cannabis plants will like a cultivation in which the nutrients are of marijuana origin. This will result in increased resistance to pests and diseases and an increase in crop quality. The ultimate goal of the organic farming method that we propose is to promote and activate the SAR (Systemic acquired resistance).
Systemic Acquired Resistance (SAR) is a plant resistance response that occurs after exposure to a pathogen. One could say that the SAR system is analogous to the immune system that animals have. When we talk about SAR, we are referring to a sort of “immune system” of plants.
If we use an inert substrate with which we need to feed the plant through chemical fertilizers, what happens is that the SAR of that cannabis plant will be weaker and will have less “defenses”, if one may say so, against possible attacks by of pests and diseases. Let’s make a simple comparison to better understand this concept: if we feed a person feeding it with the “fast food”, that person will increase in size, probably will become even obese, however this is not equivalent to being in good health, it will rather mean the opposite, surely will have a weakened immune system and will be more likely to get sick than those who follow a balanced diet.
Likewise, plants fed with chemical fertilizers will be more vulnerable than those grown in a biological system, and it is that, after all, nature can not be deceived.
