If you don’t want to use chemicals, which are always toxic (I wrote about them here), then you can also use folk remedies. Just a word of caution, they're more suitable for prevention than for getting rid of leafhoppers. pest and his harmfulness I also wrote about prevention.
However, if you are an organic lover or the drooling spittlebug has just started to appear, you can use one of the following options:
- Rinse off the foam with a strong stream of water if the plant allows it. For example, mine does, because the leafhopper is on a willow tree, and you can then remove it by hand (I'm providing a photo of the affected tree):
- Dust with crushed wood ash. Keep in mind that the ash should completely cover the entire plant. For example, if you have a potato plant, you'll need about 30-50 grams of ash.
- Buy green soap and prepare a solution - about 40-80 g per 2 liters of water, depending on the extent of the infestation.
- Prepare a solution of regular laundry soap and brown soap - 200 g per 9-10 liters of water.
- Make a celandine infusion: pour a quarter of the fresh plant into a bucket, fill it to the top with cold water, let it sit for 25 hours, and then strain. Pour this solution into another 10 liters of water. You can also grate a bar of laundry soap. For those who don't know what celandine looks like, I've attached a photo:
- Prepare a garlic infusion: peel the garlic and press it through a garlic press. You'll need a full 200 ml cup. Pour this mixture into a bucket and add 10 liters of boiling water. Cover and let it steep for a couple of hours. Strain. Once it's cooled, spray the bushes with it.
- If you have tobacco dust, pour 1 cup of it into two liters of water and bring it to a boil. Simmer for half an hour, then reduce the volume to 4 liters.
- A decoction of wormwood or tansy repels leafhoppers. Use approximately 500 g per 10 liters of water. Boil for 10 minutes after boiling, then let steep for 4 hours.
- Sprinkle slaked lime on the foamy areas.
Before spraying, etc., try rinsing the plants with water to remove foam. Additionally, if foamy spittlebug is a frequent visitor to your garden, I recommend treating the soil with a semi-fallow system in early spring.
