Spider mites are a common pest that can wreak havoc on cannabis plants, causing stunted growth, yellowing leaves, and even death if left untreated. These tiny arachnids feed on the sap of the plant, causing damage to the foliage and disrupting the plant's ability to photosynthesize. In this article, we will explore the problems caused by spider mites on cannabis and the various methods to get rid of them.
Problems caused by spider mites on cannabis:
Spider mites are tiny pests that can be difficult to spot until they have already caused significant damage to the plant. The first signs of a spider mite infestation include small white or yellow spots on the leaves, which eventually turn into brown, dead patches. As the infestation progresses, the leaves will start to yellow and wilt, and the plant may begin to lose its vigor.
In addition to physical damage, spider mites can also transmit diseases to cannabis plants, such as mosaic virus and tomato spotted wilt virus. These diseases can cause even more severe damage to the plant and can lead to reduced yields or complete crop failure.
Getting rid of spider mites on cannabis:
There are several methods to get rid of spider mites on cannabis, including natural options, synthetic options, and predator insects.
Natural options:
Neem oil: Neem oil is a natural insecticide derived from the seeds of the neem tree. It works by disrupting the feeding and reproductive behavior of spider mites, ultimately killing them. To use neem oil, mix it with water and spray it on the affected plants every 3-4 days until the infestation is under control.
Peppermint oil: Peppermint oil is another natural insecticide that can be effective against spider mites. Mix 10-15 drops of peppermint oil with water and spray it on the affected plants every few days until the infestation is under control.
Garlic: Garlic has natural antifungal and insecticidal properties that can help control spider mites. Crush a few cloves of garlic and mix them with water. Let the mixture sit for a few hours, then strain it and spray it on the affected plants every few days.
Synthetic options:
Insecticidal soap: Insecticidal soap is a synthetic option that can be effective against spider mites. It works by disrupting the cell membranes of the spider mites, ultimately killing them. To use insecticidal soap, mix it with water and spray it on the affected plants every few days until the infestation is under control.
Pyrethrin: Pyrethrin is a synthetic insecticide derived from chrysanthemum flowers. It works by attacking the nervous system of spider mites, ultimately killing them. To use pyrethrin, mix it with water and spray it on the affected plants every few days until the infestation is under control.
Predator insects:
Ladybugs: Ladybugs are natural predators of spider mites and can be effective at controlling infestations. They feed on the eggs and larvae of spider mites, ultimately reducing the population. To introduce ladybugs into your grow space, purchase them from a reputable supplier and release them onto the affected plants.
Predatory mites: Predatory mites are another natural predator of spider mites. They feed on adult spider mites, ultimately reducing the population. To introduce predatory mites into your grow space, purchase them from a reputable supplier and release them onto the affected plants.
And finally another option to control spider mites is Sulphur.
Sulfur burners: work by releasing sulfur dioxide gas into the air, which then settles onto the plant's foliage and kills spider mites. The sulfur dioxide gas works by inhibiting the respiration of the spider mites, ultimately leading to their death.
Sulfur burners are commonly used in greenhouse and indoor grow settings to control spider mite infestations. They are particularly effective at controlling spider mites in the early stages of an infestation, before the spider mite population has grown too large.
