Mustard solution from Colorado potato beetle

Insect characterization

Colorado potato beetle is an insect with an oval body, a convex head and short paws. A characteristic feature of this insect are black strips on the back, which makes it easy to identify it among other harmful insects.

The Colorado potato beetle is characterized by brutal appetite, especially they like young potato leaves, as well as foliage of other nightshade crops. A great threat to potatoes is not so much adult individuals as insect larvae. If you do not take measures to destroy them, then two weeks from the moment the first seedlings appear, they can destroy almost all the planted potatoes.

A feature of the Colorado potato beetle is its adaptation to chemical agents. Pests have a strong immunity to chemicals, so mustard and vinegar against Colorado potato beetles are an actual method of protecting potato bushes. For such components, striped insects from Colorado do not develop immunity.

The principle of the solution

Mustard itself does not act against insects, does not destroy them. The effect of using mustard seed powder is that it is the mustard flavor that the Colorado potato beetle does not like and they will not put on potato bushes that have a mustard flavor. Therefore, mustard for striped insects is a repellent, a plant that allows you to get rid of the pest by a deterrent effect, causing intolerance.

Benefits of using

  • scaring away adult insects and larvae;
  • processed potato leaves become unattractive as food;
  • mustard is combined with any, both components of chemical and plant origin, which are used in agro-technical methods of struggle against the Colorado potato beetle.

Along with mustard powder, vinegar is also used, which is added to the prepared mustard liquid.

The substance has a harsh acidic taste and a specific odor. Using this fluid, you must be very careful and accurate, since contact with the substance can be dangerous to humans.

Precautionary measures

  1. It is forbidden to bring vinegar close to the front and take sharp breaths, because burns of the respiratory tract, nasopharynx and mucous membranes, including the eyes, can occur.
  2. Do not get a bite in undiluted form on the skin, because you can also get a burn. Also dangerous is the ingress of liquid on scratches or wounds on the surface of the skin.

Vinegar acts on insects in a different way, a strong concentration of this agent enters the body of the insect and expels its insides. The concentration of vinegar liquid should be 9-10%, so that there is no damage to potato shoots.
