A lot of insect pests attack the garden every season.But some of them are so clearly parasitic on the beds that they can not be overlooked. These pests include Colorado beetles. Each summer resident of the Colorado potato beetle and the fight against it are associated with certain difficulties. The main reason for the hatred of the garden gardeners for this little bug is its voracity and quantity. The spread of the species occurs quickly, and it is very difficult to prevent its settlement in all the plants it prefers. This scum can be brought out of the garden only when using effective means at an early stage of infection.
Brief description of the form
The pest owes its name to the US state of Colorado, where its large-scale invasion of potato fields was recorded. The insect itself belongs to the family of leaf beetles and was first found in Mexico. There it specialized in the destruction of tobacco leaves and nightshade. Later the leaf beetle spread to the north of the mainland, where it adapted itself to eat potato tops.
The Colorado potato beetle is very noticeable on plants due to its bright colors - yellow and black stripes. It is the best known pest of potato tops.The size of the leaf beetle usually does not exceed 1 cm in length. But in width it is almost as much.
Photos of the Colorado potato beetle demonstrate its visibility against the background of dark green leaves. The rounded body covers the chitinous layer, under which the wings are hidden. The beetle flies perfectly, so its invasion of the gardens can take anyone by surprise to the owner of potato plantations.
On a note!
Beetle damage to about 80% of the green shoots of potatoes leads to the loss of at least half of the crop.
Leaf beetles have an enviable fecundity. One female is able to lay about 500 eggs at a time. Laying can be found on the back of the leaves of the potato. Red small eggs are impressive in their quantity. The larvae that hatch from them are bright red insects with a black head and limbs. They are very similar to formed beetles, but do not have a protective shell of chitin.
Red beetles have no less appetite than adults. Feeding on the soft parts of the leaves, they leave behind only the median veins. After 2-3 weeks the larvae descend into the ground for pupation.After another 2 weeks, an adult individual is formed from the pupa, which can remain in the ground until the next spring or crawl out and continue sabotage.
Striped insects in addition to potatoes are not averse to feast on the leaves of other garden crops:
In order to save potatoes or other garden crops from a ruthless and voracious pest, it is necessary in time to apply effective methods to combat the Colorado potato beetle. The extermination of the beetle is the destruction of all insects at different stages of development: eggs, larvae and adults.
Fighting the Colorado potato beetle
Before you get rid of the Colorado potato beetle in the garden, you need to analyze the situation. If insects appeared on plants in the initial period of vegetation or flowering, it threatens to lose most of the crop, as the inflorescences can be damaged. Weak flowering will attract few pollinating insects, and the plant may remain hollow flowers.
In such risky cases, control measures must be quickly taken and brought to action.Any hitch will cause the death of most of the crop. In another situation, when beetles were found on potatoes in the final period of the formation of root crops, they pose no great danger to the crop. For different cases it is advisable to apply the appropriate methods of dealing with the Colorado potato beetle.
Among the wide variety of anti-pest agents there are several treatment options:
- the use of biological preparations that do not adversely affect the fruits of the plant (Bitoxibacillin, Colorado, Bowerin, Fitoverm, Agravertin);
- use of potent chemicals which are applied in accordance with the instructions and in compliance with safety measures ( Aktara , Sonnet, Corado , RegentKonfidor);

Every year I process potato beds with bitoxibicillin. Reliable and inexpensive remedy for bugs. The main thing in this process - time to understand when to poison the Colorado potato beetle. As soon as I see red larvae on the leaves, I immediately spray the solution. Then again in 7-10 days. I use this tool for the third season, so far without complaints.

- To poison the Colorado potato beetle with chemistry, a special sprayer or spray gun should be used, which should not be used for other purposes.After the treatment is finished, rinse all parts of the sprayer, dry them and store in non-residential premises separately from food.
Aktara
The Swiss insecticide contains the active ingredient thiamethoxam, which is absorbed by the plant through the surface of the leaves or through watering the soil. Entering pests with food, the poison destroys their nervous system. After 30 minutes the insect cannot move and dies.
For spraying you need to prepare a solution at the rate of 4 grams of the substance per 1 liter of water. Apply the composition should be immediately. To poison the Colorado potato beetle on potatoes should be in sunny weather at temperatures above 25 degrees Celsius.
On a note!
If it rains after treatment, it will wash away most of the drug from the leaves, and the result will be zero. Before treating the plants, you need to make sure that rain is not expected in the next day.
With the help of Aktar can not destroy the eggs of the Colorado potato beetle. But the larvae that have emerged from them will eat tops to be processed. The residual content of toxin in the foliage lasts about a month.
Regent
Highly effective contact-intestinal pesticide can poison pests of potato beds in one application. Regent can be used in the fight against leaf beetles, who have already developed immunity to certain insecticidal agents.
The advantage of this drug is its effectiveness even at high air temperatures. One day after spraying, all insects die. Insecticide, getting inside through food or direct contact, paralyzes the internal organs of striped leaf beetles.
Regent is available in the form of a concentrated liquid in ampoules or in the form of odorless powder. During the preparation of the working solution and the application itself, it is necessary to observe safety measures: wear glasses or a mask, cover all parts of the body with protective clothing.

I have heard many times about different ways of pest control, but I wanted to find a recipe for how to get rid of the Colorado potato beetle forever. After reading the reviews of the celandine, I decided to try this recipe: I filled a third of the plant's bucket with water and boiled the solution for 15 minutes. Then the liquid is cooled and diluted with water in the ratio of 1 liter of broth to 10 liters of water. After one spraying, all insects die.

For many years, I fought the beetle, collecting it by hand. And recently I stumbled on the Internet for feedback on the fight against the Colorado potato beetle and found a new way for myself. One bag of mustard powder is dissolved in a bucket of water and 100 ml of vinegar 9% is added to the same place. Instead of mustard is allowed to use red pepper. By spraying such a solution, you can kill all insects. The effect is instant!
