Cannabis

Root pathogens such as Pythium, Rhizoctonia, Fusarium, and Phytophthora are major threats during the cannabis propagation phase. These soilborne diseases attack young roots and stems, causing damping-off, root rot, poor rooting, and weakened plant development. Infected cuttings and seedlings may show symptoms such as yellowing, wilting, stunted growth, or sudden collapse. Warm, wet growing conditions and overwatered substrates can increase disease pressure. Early prevention through proper hygiene, environmental management, and biological solutions is essential to maintain healthy root development and successful cannabis propagation.

Biological control of root pathogens in cannabis

Trianum-P is Koppert’s biological solution for preventing and controlling root pathogens during the cannabis propagation phase. Based on the beneficial fungus Trichoderma harzianum T-22, Trianum-P colonizes young roots and protects them against damaging soilborne diseases such as Pythium, Rhizoctonia, Fusarium, and Phytophthora. It works by competing with pathogens for space and nutrients, parasitizing harmful fungi, and strengthening the plant’s natural defenses.

In cannabis propagation, Trianum-P supports stronger root development, improved nutrient uptake, and more uniform plant growth — helping young plants establish quickly under high-pressure conditions. The product can be applied preventatively through drench or irrigation systems immediately after sowing or sticking cuttings for optimal root zone protection.

Root aphids are destructive cannabis pests that feed on plant roots, reducing nutrient uptake and weakening overall plant vigor. Infestations can lead to slower growth, yellowing plants, reduced yields, and increased susceptibility to root diseases. Because root aphids develop below the growing media surface, early detection and preventative biological control are essential.

Biocontrol solutions for root aphids in cannabis

• Entomite-M – Contains the predatory mite Stratiolaelaps scimitus, which feeds on root aphid eggs and larvae in the growing media.
• Aphipar – Beneficial parasitoids that help reduce aphid populations by parasitizing aphids before infestations spread.
• Aphidend – A banker plant system that supports continuous populations of beneficial insects for preventative aphid management.
• Chrysopa – Predatory green lacewing larvae that feed on root aphids and other soft-bodied pests, helping reduce pest pressure naturally.

Spider mites are one of the most damaging pests in cannabis cultivation. They feed on plant cells, causing stippling, discoloration, webbing, and rapid plant decline. Under warm and dry conditions, spider mite populations can spread quickly throughout the crop, impacting plant health and yield.
