Identifying Pests and Diseases in Cannabis Plants
Identifying Common Pests and Diseases in Cannabis Plants is important when growing cannabis plants. As a cannabis cultivator, it is essential to be able to identify common pests and diseases that can affect your crop. Knowing the signs of an infestation or infection can help you take timely action to prevent further damage, while also helping you create a preventative plan for the future. In this blog post, we’ll discuss some of the most common cannabis pests and diseases, as well as how to spot them and treat them.
Common Pests
The most common pests in cannabis plants include spider mites, aphids, fungus gnats, whiteflies, caterpillars, and thrips. Spider mites are tiny arachnids that feed on the undersides of leaves; they produce fine webbing as they spread across the plant surfaces. Aphids are soft-bodied insects that feed on plant sap; they can cause stunted growth and leaf curling. Fungus gnats are small dark flies that live in soil; they can damage roots with their larvae. Whiteflies are small white bugs that fly around rapidly when disturbed; they can transmit viruses and stunt growth. Caterpillars have long bodies covered in hairs; they eat large chunks out of leaves. Thrips are tiny flying insects that feed on flower petals; they leave behind black spots on buds and foliage.
Identifying Diseases
Common diseases in cannabis plants include powdery mildew, root rot, wilt, nutrient deficiencies/burns, downy mildew, grey mold (botrytis), mosaic virus infections, phytophthora blight/root rot complex (PBRR), leaf curl virus infections (LCV), brown patch fungus (Rhizoctonia solani), Pythium root rot (Pythium spp.), etc. Powdery mildew looks like a white powdery coating on leaves. Caused by high humidity levels and low air circulation. Root rot is caused by over-watering or poor drainage. It causes dark spots on roots which can eventually lead to wilting leaves. Wilt is caused by too little water or too much heat; it causes drooping leaves due to dehydration or sunburn damage from too much direct sunlight exposure without any protection from shade or windbreaks.
Also with diseases in cannabis plants are Nutrient deficiencies/burns that occur when there’s an imbalance of nutrients in the soil. Yellowing leaves indicate an iron deficiency. While burnt tips indicate an overabundance of nitrogen or other nutrients like phosphorus or potassium. Downy mildew appears as yellow spots on upper leaf surfaces with fuzzy grayish-white patches appearing underneath leaves. Caused by high humidity levels but poor air circulation combined with warm temperatures during wet conditions. Grey mold (botrytis) appear as fluffy gray patches that form around buds and stems during flowering stages when temperatures drop below 10 degrees Celsius at night combined with high humid levels during wet conditions for long periods of time.
Mosaic virus infections look like yellow patterns along veins while LCV infections cause discoloration along veins plus distorted leaflets resembling curly fries shape while PBRR causes yellow circles on lower fan leaves near the base of stems.
Conclusion:
Identifying pests and diseases early is important for protecting your crops from serious damage or even death! By being vigilant about keeping an eye out for common pests. Such as spider mites, aphids, fungus gnats, whiteflies, caterpillars, thrips etc. You will be able to take swift action should any unwanted visitors make their way onto your plants!
