Using RootShield for Cannabis Production

Using RootShield for Cannabis Production Professor DeBacco Reference Poster… https://www.researchgate.net/profile/... What Is RootShield® Plus WP? Active Ingredients: Trichoderma harzianum strain T-22, Trichoderma virens strain G-41 An organic biological fungicide with dual active ingredients to prevent a broad spectrum of root diseases and promote healthy root systems. Registered for use in: USA except AKREI: 4-hourPHI: 0-day This biocontrol agent has been reported to be affective against a range of root pathogens (Eladet al., 1982). In this study Rootshield®PLUS WP (BioWorks) was applied at a rate of 0.02% Biofungicides in General Evaluation of biological agents against pathogenic fungi can be challenging due to the environmental variability that naturally exists. When looking at studies comparisons that are focused on a single pathogen may seem limiting form a growers viewpoint but it does offer usable information. Fusarium oxysporum and Fusarium proliferatum These pathogens have been isolated from all stages of plant growth, from vegetative cuts to mother plants that typically show wilt symptoms. Treatments Impact on Disease Rootshield, containing Trichoderma harzianum, reduced infection. Conclusion Based on Cannabis Data Provided Rootshield produced a notable level of disease reduction However, Regalia produced a statistically significant level of disease reduction Based on this data Regalia may be the better option, but Rootshield would still potentially offer some protection and it may also offer reduction in other diseases so it can be considered as a potential biopesticide when it comes to cannabis production.

Effect of Colonization of Trichoderma harzianum on Growth Development and CBD Content of Hemp (Cannabis sativa L.). Microorganisms. 2021; 9(3):518. https://doi.org/10.3390/microorganism... https://www.mdpi.com/2076-2607/9/3/51... Study Specifics This study aimed to investigate the effect of Trichoderma harzianum inoculation on agronomical and quality characteristics of two monoecious hemp (Cannabis sativa L.) varieties, Fedora 17 and Felina planted in 12 L pots filled with soil and 8 L of compost. The product used: Trichoderma harzianum was the commercial product Trianum-P by Koppert Biological Systems. This product contains water-dispersible granules of 1% w/w Trichoderma harzianum strain T-22 with 1 x 1012 colony forming units (CFU) kg-1. A greenhouse pot experiment was conducted in a completely randomized design of two treatments of Trichoderma harzianum with a low and high dose of the fungus (T1 and T2). The split-application was carried out through fertigation 10 and 30 days after sowing (DAS). Yield characteristics and CBD content Yield characteristics and CBD content as affected by different Trichoderma harzianum treatments in hemp varieties Fedora 17 and Felina. Conclusions The highest values of plant height and dry weight were noticed for T2, especially in variety Felina. Trichoderma harzianum positively influenced characteristics of inflorescences such as their number, fresh weight moisture, and compactness in both varieties, while the dry weight, length, and dry yield of inflorescences were not improved. Finally, the fertigation of Trichoderma harzianum in hemp plants was beneficial by increasing the cannabidiol (CBD) content, especially in T2 treatment (4 x 1012 CFU kg-1).
