We will be contacting all potato growers to either continue to be vigilant and deal with the potato beetle infestation or have their potato plants cut from the ground up to remove the infestation. Potato beetles can eat potatoes, sweet potatoes, tomatoes, peppers, and a variety of other plants, though they usually prefer potatoes.
Robert soaked Rhubarb Leaves in water over a week, then used it as a spray to deal with potato beetles - it seems to work. Here is a faster recipe from http://tipnut.com/natural-pesticides/:
Rhubarb Leaf Mix
1 cup rhubarb leaves
6.5 cups water
1/4 cup liquid dish detergent or soap flakes
6.5 cups water
1/4 cup liquid dish detergent or soap flakes
- Cover rhubarb leaves with water and bring to a boil. Boil for 20 minutes then remove from heat and cool. Strain then add 1/4 cup liquid dish detergent. Apply. Good for aphids, june beetles, spider mites, thrips.
- Rhubarb leaves are poisonous, take care when preparing and handling. Do not use on food bearing plants.
