◉ Regular Inspection: It's crucial to check plants regularly, particularly during dry periods when planthoppers are more likely to attack. Thoroughly examine the plants, including the undersides of leaves, where the insects tend to hide. ◉ Spinosad Products: Spinosad-based insecticides, safe and organic in nature, can be used to directly kill planthoppers upon contact. These products should be sprayed liberally, especially under the leaves where planthoppers are commonly found. They are effective against the pests while being harmless to pets, children, plants, and beneficial insects. ◉ Insecticidal Soaps: Fatty acid salts or insecticidal soaps weaken the outer shell of planthoppers without causing harm to plants. Ensure comprehensive coverage during application, as the soap doesn't persist on the plant for long periods. Follow-up treatments may be necessary. ◉ Neem Oil: Neem oil is an all-natural remedy that effectively combats various pests, including planthoppers. However, it can leave an unpleasant taste and smell on buds, so it should be kept away from flowering plants. Care should also be taken as neem oil may be harmful to humans. ◉ Beneficial Insects: Introducing beneficial insects like lady beetles, parasitic wasps, ladybugs, and lacewings can help control planthopper populations. These insects consume significant numbers of planthoppers and are beneficial to the garden ecosystem. Ordering ladybugs can be an option, but keep in mind that they may fly away after a short period. ◉ Floating Row Covers: Using lightweight netting or mesh covers known as floating row covers can physically prevent planthoppers from reaching plants while allowing light and water to pass through. This method is more effective for smaller plants and can protect them from wind and harsh conditions. ◉ Pyrethrin: Pyrethrin-based insecticides, relatively safe for humans, can be considered as a last resort. However, they are toxic to bees, so caution must be exercised, especially if cannabis plants attract bees. Applying pyrethrin products in the evening allows for partial breakdown before bees become active. ◉ Remember to follow the instructions and precautions provided with any product used to ensure safety and effectiveness in managing planthopper infestations on cannabis plants.
