What is whitefly in cannabis?

The whitefly ( Bemisia tabaci ) is a tiny but tenacious insect that feeds on the sap of marijuana plants . Although its size may be deceptive, its ability to damage plants is considerable . These insects carry viral diseases and can significantly weaken plants by sucking sap from leaves and transmitting toxins.

Whiteflies are easily recognized by their distinctive appearance, with white wings and a pale yellow body. They tend to congregate on the underside of leaves, where they lay their eggs and feed on the plant.

How to detect the appearance of whiteflies?

Early detection of whitefly is essential to control its spread and minimize damage to plants. Here are some common signs that may indicate the presence of this pest:

• Yellow or silver spots on leaves : Whiteflies suck sap from leaves, leaving yellow or silver spots on the surface.
• Presence of flying insects : Look carefully at the leaves and look for the presence of small white insects flying around the plant. These are the adult whiteflies.
• Sticky spots on leaves : Whiteflies excrete a sticky substance called honeydew, which can accumulate on leaves and attract fungi and other pests.
• Plant weakness and wilting : If you notice your plants appearing weak or wilted without an apparent cause, they may be being attacked by whiteflies or other pests.

How to get rid of whitefly in bloom?

Fighting whitefly during the flowering stage can be challenging, as it is crucial to avoid using chemicals that can affect the quality and flavor of the buds. Here are some effective strategies to eliminate whitefly during this crucial phase of the plant's life cycle:

• Natural attractants : Some aromatic plants, such as basil and mint, act as natural repellents for whiteflies. Planting these herbs around your marijuana crop can help keep these insects away.
• Manual control : Use a handheld vacuum to manually remove whiteflies from leaves. This can be laborious, but it is an effective way to reduce the insect population without resorting to chemicals.
• Sticky traps : Place sticky traps around your plants to catch adult whiteflies. These traps can help reduce the insect population and control their spread.
• Biological control : Introduce beneficial insects, such as ladybugs and predatory mites, which feed on whiteflies and can help control their population naturally.
• Natural oils and extracts : Essential oils, such as neem oil and garlic oil, are effective in repelling whiteflies and other pests naturally. Dilute these oils in water and apply them on the leaves of your plants to protect them.
• Natural fungicides and pesticides : Some natural fungicides and pesticides, such as baking soda and garlic extract, can help control whiteflies without harming your plants or affecting the quality of the buds. Apply these products sparingly and follow the manufacturer's instructions to avoid unwanted effects.

By combining these strategies and keeping a constant eye on your plants, you can significantly reduce the risk of whitefly infestation during the flowering stage and protect the health and yield of your marijuana crop.
