To combat this pest, gardeners often use various home remedies in addition to chemical insecticides. One of the most effective ways is to use vinegar and dry mustard.
Below is a method for preparing a folk remedy for Colorado potato beetle.
Pour 100 ml of vinegar into a deep bowl, add 200 g of mustard powder and mix well. You will get 300 g of mustard mass, which you must then dissolve in 10 liters of water.
