     DETAILED DESCRIPTION OF THE INVENTION 
     In a following description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration a specific example in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the embodiments. 
     General Overview: 
     It should be noted that the descriptions that follow, for example, in terms of a method of determining terpene-based biocontrol agents for cannabis and hemp is described for illustrative purposes and the underlying system can apply to any number and multiple types terpene isolates. In one embodiment of the present invention, the method of determining terpene-based biocontrol agents for use on cannabis and hemp can be configured using plant terpene isolates derived essential oils. The method of determining terpene-based biocontrol agents for use on cannabis and hemp can be configured to include multiple cultivars testing and can be configured to include using individual terpene isolates at various dilutions using the embodiments. 
     Terpenes as Natural Fungicides: 
     Terpenes are major components of plant derived essential oils used by humans for thousands of years, and they are abundant in unique combinations in cannabis. Terpenes can be used to distinguish cultivars from one another, many terpenes have documented medical effects in humans, and terpenes also have a natural role in the plant&#39;s interaction with its environment. Data from flower samples collected in Nevada in 2018 show that certain cultivars fail for mold much more often than others. 
     We consider several possible explanations for higher mold failure rates on certain cultivars and discuss some basic agricultural considerations that can impact the microbiological environment including currently available commercial fungicides derived from plant sources. Addition of individual terpene isolates at various dilutions showed decreased mold growth versus a control when added to failing client samples. This indicates that some terpenes may inhibit mold species present in the commercial environment. And the antifungal effect of each terpene addition was also related to the natural terpene profile of each particular cultivar. 
     Terpenes are major components of plant derived essential oils and have been used by humans for thousands of years. Terpenes play a natural role in a plant&#39;s interaction with its environment including repelling pests and attracting pollinators. Mold presents a difficult problem for many cannabis cultivators, resulting in about 15% failure rate for flower. Mold infections increase cultivators cost and present potential health risks for consumers. Synthetic fungicides also present their own regulatory, economic, and health risks. The production of terpenes by cannabis plants are used as naturally-derived microbial control agents. Not only can terpenes be used to distinguish and categorize cannabis cultivars from one another, we noticed that certain cultivars fail for mold much more often than others and it can be tied to their terpene chemoprofile. The use of prophylactically applied terpenes as natural biocontrol agents has the added benefit of augmenting the resulting terpene content in the dried flower and products made from the flower including extracts, imbuing added benefits to the cannabis user. 
     This preliminary data suggests that individual terpenes or terpene mixes may be effective as fungicides and broad spectrum biocides during cultivation, and that effective terpene mixes may be optimized for different cultivars. Cannabis derived terpene fungicides and biocides may also be effective on other crops. As an aside I see a secondary benefit to the use of terpenes for biocontrol on cannabis which is that the terpene content of the resulting crop can/could be influenced in a positive way since terpenes are bioactive molecules in mammals as well. 
     Cannabis terpene-mimickry in beer to define terpene profiles in hops and options during and after the beer brewing process to influence the resulting terpene profile contribution for aroma, flavor, and specific physiological outcomes in the end user including but not limited to cannabis strain specific terpene-mimickry. 
       FIG. 1  shows for illustrative purposes only an example of placing terpene-soaked discs in a pattern onto bacterial inoculated plates of one embodiment.  FIG. 1  shows an example of a method of determining terpene-based biocontrol agents for cannabis and hemp by placing terpene-soaked discs in a pattern onto the bacterial inoculated plates in duplicates with a diluent-soaked negative control disc in the center  100 .  FIG. 1  shows an example a bacterial inoculated plate  110  with a diluent-soaked negative control disc  130  in the center and terpene-soaked disc #1  120  and a terpene-soaked disc #1 duplicate  122 . This prepares the samples for testing of the efficacy of a terpene fungicidal and broad spectrum microbiocidal function in controlling mold on various cannabis plants. 
     Terpenes are the Next Frontier in therapeutic impacts. Current thought is that there is no end to the phytocannabinoid pharmacological revelations from a highly effective pain management alternative to a non-toxic anti-cancer remedy of cannabidiol (CBD) and tetrahy drocannabinol (THC), the two powerhouse cannabinoids respectively. However, the phytotherapeutic story is shifting to what will be a dramatic ascendency of terpenes and their therapeutic impact either individually or in concert with THC and/or CBD. Terpenes heretofore have been used predominantly as flavorings and fragrances common in our diet, and are considered GRAS compounds by the US Federal and Drug Administration and have no controlled substance restrictions associated with phytocannabinoids. 
     It turns out that terpenes are affecting us much more than we might think. As examples: limonene is a strong anxiolytic, is active against bacteria associated with acnel and can induce the suicide of cancer cells. Another terpene beta-caryophyllene is a nonpsychoactive anti-inflammatory via CB2 binding. Another beta-myrcene is a sedating muscle relaxant anti-inflammatory. Yet another terpene alpha-pinene, the most abundant terpene among all plants is an antimicrobial and more importantly acts as an acetylcholinesterase inhibitor which may aid in memory loss associated with several human neurological diseases. 
     The rising eminence of terpenes couldn&#39;t be coming at a better time for the cannabis industry that needs a strategy for demarcating medical marijuana from recreational marijuana. Today, terpenes constitute the medicinal subtlety of the entourage effect that we all keep hearing about. There are probably more biopharmaceutical messengers yet to be revealed by this most extraordinary plant,  Cannabis sativa  L. 
     Few cannabis complicit states even require testing and reporting of terpenes. Most cannabis consumers remain in the dark about the importance of terpenes. The State of Nevada was the first state to have the foresight to require reporting of 11 terpenes as a component of potency. 
     Unfortunately, many cannabis extract producers are unaware that their procedures are basically throwing away the terpenes to the atmosphere rather than bringing them along with the two powerhouses, THC and CBD, which remain the coveted measure of wholesale valuation. Clearly, retaining the entire terpene complement going forward appears to be worth the effort during cannabis extraction. 
     Not surprisingly, it was Ethan Russo&#39;s review article in 2011 that portended the current therapeutic extent of cannabis-derived terpenes on human health and behavior. Remarkably, terpenes are potent even when inhaled in ambient air and can subsequently be detected at quantifiable levels in your serum. 
     Terpenes and cannabinoids (also chemically known as phenolic terpenes), share a common biochemical precursor, geranyl pyrophosphate and over 10,000 terpenes have been identified, albeit their biochemical and genetic pathways are not completely resolved. Another consequence of the focused spotlight on THC and CBD. 
     Terpenes act remarkably in concert with phytocannabinoids and in particular to diminish the intoxicating effects of THC. From the MMJ side of the industry, if the intoxicating effect of THC can be controlled, reduced or eliminated while maintaining its therapeutic merits, the application of cannabis derived products could be expanded dramatically. Terpenes can make up to 10% of trichome content but are subject to loss from processing and subsequent drying and storage. Terpenes come in different formats with the three monoterpenes, limonene, alpha-pinene and beta-myrcene dominating, followed by sesquiterpenes, like beta-caryophyllene and alpha-humulene. Importantly, just like cannabinoids, terpene synthesis is under genetic control. 
     From a pharmacological standpoint, terpenes are highly evolved lipophilic molecules that can interact with other lipophilic structures like membranes and the many embedded receptors that reside there, resulting in neurological responses, the detection of odors, downstream enzymatic changes or acting as a THC antidote. Terpenes&#39; lipophilic (hydrophobic) nature also gives them the unique ability to permeate skin. Remarkably, the use of terpenes as facilitating permeants in topical formulations not involving cannabinoids was reported 13 years ago. 
     Topically applied drugs must somehow permeate the stratum corneum or the outermost layer of epidermis, layers of dead cells embedded in a lipid matrix. Topicals passing through the stratum corneum must either move into cells (intracellularly) or move between cells (intercellularly) and the lipophilicity of the compound formulation is the key. Cornwell et al. found that formulations with high levels of specific terpenes could increase permeation by up to a 1,000-fold with the intercellular concentration of limonene, cineole and nerolidol reaching 40-60% of the tissue treated with neat terpenes. Plants are clearly better remedies than the extracts made from them and stand apart from the empty promise of modern pharmaceuticals. Going forward, more attention needs to be focused on the contribution of terpenes both individually and in combination with phytocannabinoids.

     Detailed Description: 
       FIG. 2  shows for illustrative purposes only an example of terpene concentrations plot analysis of terpenoid data of one embodiment.  FIG. 2A  shows an example of a terpene concentrations plot analysis of terpenoid data  200 . The graphical display of the terpene concentrations plot  210  of the terpenoid data clearly shows the effective distribution of terpene sample tests. This method of analysis aids researchers in a arriving at a clear understanding of the evaluations and helps them to direct their attention to the most effective applications of one embodiment. 
     An unintended consequence of state-mandated cannabis testing regulations has been the resulting database from the analysis of thousands of individual cannabis flower samples from artificially restricted geographical regions. The resulting detailed chemical database can serve as the basis for the development of a chemotaxonomic classification scheme outside of conjectural cultivar naming by strain. Chemotaxonomic classification schemes for cannabis cultivars have previously been reported by others based largely on cannabis strains grown in California under an unregulated testing environment or in Europe from strains grown by a single cultivator. In this study 2,237 individual cannabis flower samples, representing 204 individual strains across 27 cultivators in a tightly regulated Nevada cannabis testing market, were analyzed across 11 cannabinoids and 19 terpenoids. 
     Even though 98.3% of the samples were from drug Type I cannabis strains by cannabidiolic acid/tetrahydrocannabinolic acid (THCA) ratio of &lt;0.5 CBDA, principal component analysis (PCA) of the combined dataset resulted in three distinct sample group  220  of data that were distinguishable by terpene profiles alone. Sample group #1  230 , sample group #2  240 , and sample group #3  250  show the data results of three different terpene profiles. Further dissection of individual strains by cultivators within samples revealed striking fidelity of terpenoid profiles and also revealed a few outliers. We propose that three terpenoid sample assignments account for the diversity of drug type cannabis strains currently being grown in Nevada of one embodiment. 
     Profiled Chemicals: 
       FIG. 3  shows for illustrative purposes only an example of profiled chemicals of one embodiment.  FIG. 3  shows examples of profiled chemicals  300  including a listing of examples of cannabinoids  310  and terpenoids  320 . The objective is to identify unique combinations of plant-derived terpenes for use as prophylactic applications on cannabis plants to control either fungal or bacterial populations and/or mites and aphids as 100% natural, non-toxic plant-powered “terpenated pest control” with the added benefit of terpo-charging the resulting cannabis crop. 
     Mean Terpenoid Content Test Results: 
       FIG. 4  shows for illustrative purposes only an example of mean terpenoid content test results of one embodiment.  FIG. 4  shows a bar chart of mean terpenoid content test results  400 . The lack of horticultural or agronomic naming conventions and registrations in the cannabis industry has created a confusing collection of strain names, making authenticity questionable for the cannabis consumer. Various efforts have been underway to make sense of cannabis strain names through the use of data analytics on broader cannabis flower chemoprofiles beyond strictly tetrahydrocannabinol (THC) and cannabidiol (CBD) potency even though harvesting a consistently reproducible cannabis crop is challenging under the best of agronomic standards. 
     There are many environmental factors besides genetics that can impact the resulting chemical content of an agronomic plant. Reports indicate that cannabinoid and terpenoid content varies both intra-plant, inter-plant and between harvest lots. Reducing consistently-grown cannabis to its extract is the best approach to achieving chemical profile uniformity. Cannabis drug-type plants that have a cannabidiolic acid (CBDA)/tetrahydrocannabinolic acid (THCA) ratio of &lt;0.5 are referred to as drug type I or broad leaflet drug-type (BLDT), cannabis plants with a CBDA/THCA ratio between 0.5 and 3.0 are type II or narrow leaflet drug-type (NLDT) and those plants with a CBDA/THCA ratio of &gt;3.0 are type III or hemp. 
     The obsession surrounding cannabinoids and in particular (−) trans-Δ9-tetrahydrocannabinol (−Δ9-THC) and cannabidiol (CBD) content in cannabis cultivars has overshadowed the importance of the terpenoid profile and content in specific cannabis cultivars. Today we know that terpenoids are contributing pharmacologically active compounds in cannabis and can be used to distinguish cannabis cultivars. Of the roughly 140 identified terpenoids in cannabis, there seems to be a consensus in the literature that range between 17 to 19 are the most useful in defining a cannabis chemotype. 
     Terpenoid content in the cured flower can typically range from 0.5% to 3%. Terpenoids demonstrate effects on the brain at very low ambient air levels in animal studies. Generally speaking terpenoids contribute a sedative and anxiolytic effect to cannabis with more specific pharmacological effects attributed to individual terpenoids; such as, pinene exhibiting antibiotic activity [14] or β-caryophyllene providing gastric cytoprotective activity [15] or the anticonvulsive effects of β-myrcene. 
     Previous groups have made great strides in demonstrating that terpenoid content can be used to distinguish cannabis strains, varieties or cultivars based on the nomenclature in use. These studies have also highlighted the importance of obtaining cannabis samples of sufficient size and representativeness to result in a valid test. Notably, previous reports demonstrate the need for the use of validated analytical test methods as well as reproducibility of sample set data. 
     In 2010, Fishedick et al. showed that across 11 cannabis varieties, all grown by one cultivator, each variety was distinguishable based on the occurrence of 36 different chemical compounds including 27 terpenoids using principle component analysis (PCA). A recent genomic analysis of diversity among 340  Cannabis sativa  L. varieties demonstrated the existence of three major cannabis groups represented by BLDT, NLDT and hemp [21]. In an elegant time course study over the growth cycle of specific chemotyped cannabis plants Aizpurua-Olaizola et al. [1] found differences in the evolution of monoterpene and sesquiterpene patterns within chemotypes. Here we report on the analysis of the chemoprofile data for 2,237 individual cannabis flower samples representing 204 individual cultivars across 27 cultivators in a tightly regulated Nevada cannabis testing market. Even though all of the samples except for 1.7% of the samples were type I based on CBDA/THCA ratio, the terpenoid chemoprofiles distinguished the samples into three separate samples of one embodiment. 
     A Method of Evaluating Individual Terpenes for Effectiveness: 
       FIG. 5  shows for illustrative purposes only an example of a method of evaluating individual terpenes for effectiveness of one embodiment.  FIG. 5  shows a method of evaluating individual terpenes for effectiveness in controlling common fungal and bacterial populations. The method includes one sample in an EB Plate that is a control sample. Mold Plate 1, Mold Plate 2, and Mold Plate 3 are samples of terpene-soaked discs in a pattern onto bacterial inoculated plates as described in  FIG. 1 . Each of the Plates represents a terpene-soaked disc that is placed in the petri dish in the pattern shown in  FIG. 1 . The specific aims are to evaluate individual terpenes for effectiveness in controlling common fungal and bacterial populations found on indoor and outdoor grown cannabis plants. 
     At least one device for mixing formulated individual terpene isolates concentrations and for mixing formulated combinations of individual terpene isolates concentrations. At least one device for applying at least one of the mixed terpene formulations on cannabis seedlings and plants is used for field testing terpene inhibition treatments. An infrared camera with Wi-Fi and cellular connectivity coupled electronically to a digital server using cellular connectivity captures time-stamped images at intervals of microbial species infected cannabis seedlings and plants growing indoors or outdoors that have been treated with at least one application of at least one embodiment of a terpene isolates concentration. The infrared images detect the areas of the microbial infections and record on server databases the progress of the inhibition of the microbial growth. 
     The server scanner with OCR converts the time-stamped data into digital data that is recorded with the infrared images on the digital server database. An algorithm of the digital server computer measures the infected surface areas and records those measurements on the digital server database. The computer coupled to the digital server analyzes any changes in the infected surface areas and records those changes and the time interval between the images to determine a rate of change. The changes and rate of change allow an evaluation to be performed in a digital processor to determine an inhibition effectiveness of the inhibition of the microbial growth of the embodiment of a terpene isolates concentration of one embodiment. 
     Terpenes to be evaluated by anti-microbial category for fungi include eugenol, geraniol, alpha-bisabolol, alpha-terpineol, caryophyllene oxide, nerolidol, and ocimene. Terpenes to be evaluated for anti-bacterial activity include thymol, citral, limonene, linalool, caryophyllene oxide, and nerolidol. Terpenes to be evaluated for activity against Mites/Aphids include terpinolene, para-cymene, and ocimene. 
     The method of determining terpene-based biocontrol agents for use on cannabis and hemp include processing steps that include a. Isolate epiphytic microorganisms from cannabis ‘flower wash’ and isolate into pure cultures. b. Grow up individual fungal or bacterial broth cultures with shaking at RT until turbidity is evident; if, possible take OD 600 nm  reading of turbidity for each culture just prior to plating out serial dilutions onto agar plates to determine ˜CFU/ml. c. Based on CFU data from (b) above, re-inoculate fresh broth cultures for individual cultures monitoring OD 600 nm  to reach previous data point and make appropriate dilutions to attain complete seeding on agar petri plate. d. While allowing bacterial suspension to be absorbed into agar, prepare terpene-treated Whatman filter paper hole punches by aliquoting 25 μl of either full strength, 1:10 dilution or 1:100 dilution. Dilutions should be made into 1-15% MeOH or 1-2% castile soap. e. Place terpene-soaked discs in a pattern onto the bacterial inoculated plates in duplicates with a diluent-soaked negative control disc in the center as seen in  FIG. 1 . i. One terpene per plate at three concentrations with negative control. ii. One microbial culture seeded per plate. f. Allow plates to grow with incubation at 28° C. for overnight and photograph as well as measuring any zones of inhibition. Continue incubation for 2 more days, taking photographs and making measurements after each 24-hr period. g. Repeat steps (c) through (f) for each terpene against all microbial cultures. 
     An optical camera and an infrared camera with Wi-Fi and cellular connectivity coupled electronically to a digital server using cellular connectivity captures time-stamped images at intervals of individual cultures during incubation. The images are analyzed for measuring any zones of inhibition and the measurement data is recorded with the time interval between images to determine the changes in the zones of inhibition and a corresponding rate of change is calculated using a digital processor coupled to the digital server and server computer. The data was further evaluated to determine the effectiveness of the terpene-based biocontrol agents treatments. 
     Sensors coupled to the digital server computer record data for detected temperatures, and changes in density of the incubated microorganisms using distances sensed from the top surface of the microorganisms to the surface of the culture plate surface. Chemical sensors perform chemical analysis of vapors being released during the incubation heating process to detect any changes in the vapor composition to identify components of the microorganisms being inhibited. 
     The testing personnel may log in to the digital server via Wi-Fi or cellular capable digital devices including laptop computer, smart phone, tablets and other digital device to review the inhibition data being collected. The digital server will send Wi-Fi and cellular alerts to the testing personnel should the data being collected register any abrupt or abnormal changes that are outside a calculated trend line of the progression of the inhibition data being gathered and recorded of one embodiment. 
     1. Test combined bioactive terpenes identified under Specific Aim #1 above for synergy. 2. Develop terpene formulations and retest as in Specific Aim #1 to ensure that added ingredients do not interfere or dampen bioactivity. 3. Test terpene formulations on cannabis seedlings for suitability. 4. Test terpene formulations in challenge experiments on cannabis seedlings. An initial timeframe to complete a battery of testing can for example be 9 months of one embodiment. 
     The data gathered from inhibition testing on living infected cannabis seedlings and plants and laboratory tested inhibition cultures are analyzed using digital processors of the digital server to determine any differences in the effectiveness of the inhibition responses between “field” testing living plants and cultures in a controlled laboratory setting. Any correlations developed between the two sets of data for example time intervals for inhibition of microbial growth, are then used to develop adjustments in concentration levels of particular terpenes to aid in the development of the terpene inhibition treatment formulations of one embodiment.
