Potato varieties resistant to the Colorado potato beetle - myth or reality?

The resistance of potato varieties to the Colorado potato beetle depends on many factors. This care, and agricultural technology, and even the "taste" of the leaves. However, it is safe to say about some varieties that the striped pest is not terrible in principle.

The Colorado potato beetle is one of the most dangerous and tenacious pests. In the fight against it, humanity is losing. Why? Insects actively reproduce, due to this, the population already in several seasons reaches hundreds, and even thousands of individuals. Adult bugs are not afraid of temperature drops and the effects of various chemicals (which would rather harm people and destroy potatoes than pests).

If necessary, the Colorado potato beetle “goes on a diet” and is not afraid of the lack of food for several months. Even by the standards of insects, the Colorado potato beetle is a long-lived: in the south there are individuals that are 3 years old! He is not afraid of almost anything.

Is it easy to deal with the Colorado potato beetle?

It is difficult to find a more cunning and fearless insect in nature than the Colorado potato beetle. For any method of struggle proposed to him, the beetle has a steady “antidote”:

  • birds and animalsas natural enemies of insects, in this case do not help. Colorado beetle is not for nothing has a bright and memorable striped color. This way, he warns everyone who wants to “eat the bug” that his body contains toxic substances that he receives from the leaves and shoots of the nightshade. Few birds and animals want to suffer from poisoning, so there are almost no natural enemies of the Colorado potato beetle. And those that do not cause damage to the population;
  • insecticide treatment. The Colorado potato beetle very quickly develops immunity to any chemicals. Therefore, they need to be constantly updated and changed. This is not always done, which allows the beetle to be fruitful further, simultaneously destroying the crop.
  • manual collection of beetles and larvae. This method is effective only in small areas, while on industrial landings it requires constant employment of a large number of people. Beetles that feel in danger pretend to be dead and lie with their paws up. At the same time, they can survive in a jar of water for 10 days, and even being frozen, they live another 2 days.

With strong winds, Colorado beetles can travel tens of kilometers.

Recently, they have started talking about another measure of struggle - the cultivation of potato varieties resistant to the Colorado potato beetle. Did you manage to fool a cunning insect?

Are there “no beetle” potato varieties?

The Colorado potato beetle is still a gourmet. Both the larvae and adult insects prefer soft, young and tender leaves and shoots. It is important for them that the plant be “tasty” and that the harsh smells of the borage (borage), garlic, calendula or beans planted next to them do not distract from the meal.

These food taboos are breeders and tried to wrap against the pest. Years of experience allowed scientists to draw certain conclusions:

  • Colorado potato beetle less often damages plants with coarse, dense leaves covered with hairs;
  • the unpleasant (from the point of view of the beetle) taste of leaves scares off the insect;
  • a high degree of regeneration of the shoots reduces crop losses;
  • the introduction of special genes into the plant's genome, which form a protein that is toxic to the beetle, makes it possible to repel an uninvited guest.

Voracious larvae cause the main damage to potatoes

In any case, it has not yet been possible to obtain a 100% absolutely resistant to the Colorado potato beetle in any climatic zone. You can talk about either relative resistance (less affected by the beetle), or the introduction of transgenic varieties, the safety of which for humans is still in question. In addition, the “tasteless” varieties for the beetle seem to be human too. Therefore, one always has to choose: either to fight the bug for the “second bread”, or to eat not the best potato that even the Colorado potato beetle does not like.

Relatively resistant to the Colorado potato beetle varieties of potatoes

We suggest to get acquainted with the selection of potato varieties, relatively resistant to the Colorado potato beetle and some diseases.

Bryansk reliable

High-yielding variety, which occupies a leading position in taste and resistance to various pests and diseases, including the Colorado potato beetle. Tubers neat, oval-rounded, with smooth skin and small eyes. The flesh is thick and juicy, suitable for various dishes.

Glow

A variety that has proven itself in different climatic zones. A consistently high yield and good keeping quality of the fruits - this is what distinguishes it from the rest. Tubers are pink, rounded, with a mesh skin and small eyes. The fruits are characterized by a high content of starch and protein, and at the same time very tasty. Due to the nature of the variety, when harvesting, some of the tubers may become covered with small cracks. To avoid this, make a little more phosphorus and potassium and reduce the dose of nitrogen in dressings.

Kamensky

Large hard leaves of this plant allow you to avoid the mass invasion of the Colorado potato beetle. It is one of the earliest ripening, high-yielding and drought-resistant varieties.

Lasock

Medium late variety, which is characterized by positive characteristics and satisfies the requirements of owners of both small plots and large agricultural enterprises. Tubers are dark beige, almost brown. The peel is smooth, little eyes, but they are deep. Yield varieties slightly above average, the main advantages are the universal purpose of potatoes and resistance to most diseases and pests. From potato varieties Lasock prepare any dishes, as well as chips, dry powder, etc.

Pace

This variety was bred before the mass epidemic of the Colorado potato beetle began. Variety Tubers Pace rather large, flat-rounded, with light yellow skin. The starch content in them is about 17-22%, so that the potatoes are perfectly boiled soft and happy with a rich and bright taste. From tubers get alcohol, starch, sublimated puree and, of course, prepare a variety of dishes. The harvest is stored for a long time, and at the same time the roots are almost not affected by various diseases and infections.

The varieties described by us can only reduce the intensity of the invasion of the “striped saboteur” on your potato plantations. No one will give you guarantees of full protection of culture, even for one season. Take care of the potatoes, observe crop rotation, and then the beetle, in any case, will have to look for other places to eat.
