The Colorado potato beetle is a very voracious and tenacious pest; it is extremely difficult to get rid of it completely.
But it is possible. The recipe for a "magic" decoction against the Colorado potato beetle is told by the expert of the online publication "Belnovosti", agronomist, landscape designer Anastasia Kovrizhnykh .
To prepare the decoction, you will need only one ingredient – celandine.
The Colorado potato beetle simply hates the smell of this plant.
For a liter of water you need 200-300 g of celandine. It should be boiled for 15 minutes (after the water boils).
Next, the decoction needs to be cooled and filtered. For spraying, dissolve 250-300 ml of decoction in 10 liters of water.
It should be noted that celandine decoction helps against many pests, not only the Colorado potato beetle.
