Powdery Mildew by Rincon-Vitova Insectory Powdery mildew (PM) is the most important fungal disease of cannabis, but also one of the most easily managed of the foliar diseases. It is a fungus that grows on the upper surface of leaves and parasitizes surface cells. Affected cells may be killed, causing brown areas on […]
By Rincon-Vitova Insectary Thrips Thrips cause damage that is similar to spider mites; they tend to scrape the leaf surface to extract the chlorophyll. Thrips are tiny pests, capable of limited flight. Thrips damage plants by feeding on leaf and flower tissue, leaving a silvery appearance. They also lay eggs in leaves and flower […]
By Rincon-Vitova Insectary Caterpillars (& Moths) “Caterpillar” is the common name for the larvae of members of the order Lepidoptera (the insect order comprising butterflies and moths). Armyworms and cutworms generally eat seedlings. Bollworms and budworms typically feed on seeds and inside flowers. Hemp Borer and European corn borer are often found inside of […]
Russet Mites (Aculops cannabicola) By Rincon Vitova Insectary Hemp russet mites are hard to control if they get started in the garden. Extremely high populations of mites may build in late summer which damage maturing buds/flowers and reduce yield and quality. They feed on foliage, including petioles, meristems and leaves. Russet mites feed on stigmas […]
by Rincon-Vitova Insectary Broad Mites (Polyphagotarsonemus latus) This destructive pest lives on a wide host range. Broad mites secrete and inject a toxic growth regulator into plants as they feed. The toxin causes twisted, hardened and distorted growth and terminal leaves and flower buds become malformed. The reason broad mites are such a problem is […]
by Rincon-Vitova Instectary Root Aphids (Pemphigus populivenae) Root aphids feed on the root system, sucking so much sap that the plants do not receive proper sustenance. Leaves turn yellow and little new growth occurs. They can move from plant to plant via the drainage holes in pots, or through irrigation water that drains from one […]
by Rincon-Vitova Insectary Aphids Aphids suck plant sap, which causes distortion of leaves and shoots and reduces plant vigor. As aphids feed, they produce sticky honeydew, which attracts sooty molds, and reduces photosynthetic capacity. Some species also transmit plant viruses. Identification Aphids are soft-bodied, pear-shaped insects, 1/16-1/8 inch long. Most are wingless, but some have […]
by Rincon-Vitova Insectary Whiteflies are not flies but are related to honeydew producing pests like aphids, scales, mealybugs. They have piercing, needlelike mouthparts to suck sap from plants. Large populations can cause plant distortion, discoloration, yellow or silvering of leaves, leaves to fall off plants, and serious crop losses. Some whiteflies transmit viruses […]
by Rincon-Vitova Insectary Ants There are more than 12,400 species of ants throughout the world. In California, there are about 270 species, but fewer than a dozen are important pests. Ants interfere with biological control. Honeydew-secreting pests, like aphids, supply sweet food to the ants. In turn, ants protect the pests from beneficial insects that […]
