The fight against the Colorado potato beetle folk remedies

Characteristic Colorado potato beetle

In order for vegetable growers to diagnose pest infestation correctly, the Colorado potato beetle must be identified that it is he. The insect can reach up to 15 mm in length and has unique identification features. On the body of an adult pest there are 5 black longitudinal stripes and yellow wings. You can also see several black spots on the yellow or orange abdomen.

Males and females are visually practically indistinguishable. Depending on weather conditions, the eggs of Colorado beetles can ripen from 3 to 15 days. Over the next 2-4 weeks, larvae develop in various stages. Then the larvae fall to the ground to penetrate deep into the soil. After about 1 month, the pests crawl as adult beetles and their life cycle repeats.

Reasons for the appearance

  • In colder climates, adults hibernate deep in the soil. In this case, it is very important to carry out soil treatment before planting potatoes.
  • When the temperature is 15 degrees and above, the beetles go hunting and begin to hit the landing. In this case, insects need to be removed from planting until the time of warming.
  • Nests are located in groups on the lowest leaves of the plant, so it is important to weed the beds in time and spud the potatoes.

Mostly gardeners carry out tillage before planting and use different methods of influencing the beetle in order to surely eradicate the pest from their site. In autumn, the soil where potato tubers will be planted must be dug deep. In deep grooves for potatoes, you can try to sprinkle fresh manure and loosen the soil between it and the plantings. During the winter, manure will burn out most of the parasites and larvae, and in the spring when snow falls from the soil, manure will be an excellent fertilizer.

You can make different mixtures such as manure with horseradish or nettle. You can deal with the pest with the help of mint, caraway seeds or mustard or sprinkle the place of planting with onion husks, wood ash. All these odors, the pest does not tolerate.

Simple ways

Manual pest collection

You can collect beetles with your hands

Many gardeners adhere to such a rule that they do not use various chemicals or even harmless folk remedies for growing vegetables. Therefore, in this case, you can get rid of the insect only by removing it from the plantings manually. To do this, wear protective gloves and inspect each potato bush. As soon as you see the Colorado potato beetle, you should remove it away from your site. Such a measure to protect your landings is considered more humane for nature, but this method of eliminating the pest requires a lot of time.

Colorado potato bug repellent plants

Properly planted plants will help prevent the spread of Colorado pest larvae. During the planting of tubers, you can throw the seeds of one of these plants into the hole:

  • Beans
  • Dill
  • Coriander
  • Calendula
  • Tansy
  • Basil

The Colorado potato beetle will not harm your plantings if it senses the presence of these plants in the soil. Also, with them you can perform the processing of mustard. Many gardeners consider it an effective way to plant garlic around the perimeter or between rows of potatoes, and with it onions. Garlic and onions have a pungent odor that the Colorado potato beetle cannot tolerate.

Hilling potatoes

Hilling helps prevent the appearance of insects in your plantations, as it creates a natural barrier to pests. Hiding young shoots in the soil layer, additional sprouts form on the plant. As a result, the bush grows, becomes more powerful and resistant to insect attacks. Potato should be earthed several times during the period of root growth — these are May, June and July.

Varieties of early potatoes can be spudded as soon as sprouts appeared, later potato varieties should be spudded when the plant has reached a height of 5-10 cm. After hilling, the soil is loosened between rows. Hilling and loosening will save your landings from nesting of eggs and bugs. After hilling around a bush of young potatoes, you can pour a little wood ash, and then onion husk. The ratio in proportion is half a glass of ash and a handful of husk. The smell of rotting husk repels the insect perfectly.

Colorado potato beetle traps

Gardeners often use so-called pest traps. In the spring, as soon as the soil woke up and the night frost ended, you can pour a bunch of potato peels on different ends of the garden. After hibernation, insects attack light prey. Here the main thing is not to miss the moment and watch when most of the pests gather. After this, the beetles should be collected in a jar and released as far as possible from their site. According to the same method, there is another option: several potatoes are laid out in a glass floor liter containers and put in small cavities across the field. When the banks are filled with pests, they need to be released elsewhere.

Using solutions

Blue vitriol

Before planting potatoes, the tubers themselves can be treated against parasites and fungal diseases. A teaspoon of copper sulfate is bred in a three-liter jar, the tubers that are being prepared for planting are lowered into the solution for 1-2 minutes. Then the tubers are dried and three days later planted in the ground. Instead of copper sulfate, manganese can be used. This is done so, one gram of potassium permanganate is diluted with a liter of water and thoroughly mixed. This solution is recommended to fill in the sprouted tubers for half an hour, and then remove, dry and plant on the third day.

In ash mixed with fertilizers, you need to plant potatoes in the usual manner and sprinkle with soil on top. Ash is also used in this embodiment: hot ash is poured into the hole to a depth of 10-15 cm and covered with soil from above. After 2 weeks, you can plant potatoes in the prepared soil.

Horseradish is thrown into a tank or barrel of 10 liters. A container of horseradish is placed in a sunny place for 2-3 days. The resulting mixture should be filtered through a sieve or gauze. Processing horseradish infusion is carried out both on young tops and on infected plants. The treatment procedure with horseradish infusion is recommended to be repeated after 2 weeks.

Peppermint infusion

With a peppermint compound, experienced gardeners spray the plantings almost every week from the start of planting potatoes to digging up the crop. For 10 liters of water, 1 kg of mint is required.
