Birch tar from the Colorado potato beetle and wireworm

In the course of unequal battles with pests, gardeners are looking for ever new means that would allow them to get a crop without losses and not be poisoned by chemistry. Already invented many folk recipes from all types of insects that can be encountered in the garden. Most of them usually intersect and act on different types of pests. Relatively recently, birch tar from the Colorado potato beetle was tested. The American aggressor unexpectedly turned out to be sensitive to substances contained in the extract from birch. Gardeners use this drug in all garden crops, including even strawberries. Although the garden berry with the smell of such a substance will not appeal to everyone.

Application

"Pure" birch tar in the garden can be used in a mixture with water. But such a tool has a drawback: it does not mix with water and clogs atomizers. Therefore, spraying the plant with this drug is impossible.

Mix recipes vary:

• 30 ml per bucket of water;
• 2 tablespoons per liter;
• 1 spoon per bucket.

The optimal ratio of tar and liquid, each gardener finds independently empirically.

Important!

This drug does not kill pests, but repels them. The Colorado interventionist flies to the smell of potatoes, but if the smell is "clogged" with fumes of birch tar, the insect will not find the plantings it needs. This is the basis for the use of tar against the Colorado potato beetle.

Processing Rules

To get the crop you need to start handle from colorado potato beetle not even the plants themselves, but also tubers when planting. Before planting, tubers are bathed in tar tar (a tablespoon of the product in a bucket of water). When planting with the same tool, grooves are shed. Such measures help against the Colorado potato beetle and wireworm.

During the growth period, potato bushes are watered from the bottle with a similar composition. From a bottle, because, as already mentioned, an oily substance clogs the atomizer nozzle. Therefore, for the tar water mixture, they take an ordinary plastic bottle and make holes in its lid. You can use a watering can. Processing is carried out every 3 days from the moment of emergence of shoots and up to the start of harvesting.

Soap solution

Due to the fact that birch tar is an oily substance that does not mix with water, it is inconvenient to use it. It is very unevenly distributed over the beds: all the oil can be poured in the first liter of the mixture. It is much more effective to use tar soap from the Colorado potato beetle, which will allow you to properly spray the plants without harming the spray gun. And the effect will be the same as with a pure birch preparation.

To scare away potatoes, Colorado beetles and their larvae make a soap solution according to the usual recipe. But instead of household, tar soap is bred. Potato tops are processed as usual. This method will evenly distribute the birch preparation throughout the beds and will last longer than the water mixture.

Although gardeners' reviews of birch tar from the Colorado potato beetle are mostly positive, but everyone notes the difficulty of using the drug because of its oiliness.

Reviews

I tried to apply birch tar from a potato pest, but I had to spray this agent with a broom. And I have a feeling that everything useful on that broom has remained. The broom stank, but the bugs wanted to sneeze at my efforts. But when I tried to dilute tar soap, it turned out that all the pests were vigorously running away from the garden.

With tar solution, I prefer to water the beds from slugs and wireworms. Try to apply it to the top of a dead number. But it works quite well in the ground, you just need to constantly “beat” the mixture. But for the "tops" I use soap based on tar. Spraying from above and watering below saves me from all insect pests.
