Pests often affect even the most well-kept areas of the garden. But scientists are not standing still in search of effective ways to combat the scourge, and now for the extermination of parasites, you can use ... other parasites. This article will tell about one of such means - the preparation "Nemabakt", the manufacturer of which is the St. Petersburg company "Biodan".
"Nemabakt": what is this drug and who is afraid of him
The main weapon of the bioinsecticide "Nemabakt" is a predatory nematode - a microscopic roundworm, as well as a bacterium infested into it, with which they form a definite symbiosis.
The nematode penetrates into the insect larva, where the bacterium eats it for several days and, in turn, provides the nematode with a source of food; the worm actively breeds inside the larva, and then leaves the empty shell to find another insect. Nematodes multiply very quickly and begin to look for new sources of food, that is, insect larvae. Nematodes settled on a plot of land continue to clean it for two to three years; at the end of autumn, they hibernate, and in the spring they are activated again.
Did you know? For the first time, the use of entomopathogenic (insect-parasitic) nematodes for controlling plant pests began in 1929. However, it was not until the 1970s and 1980s, with the development of technology, that it became possible to make wide use of them in agricultural technology.

Drug benefits
Indisputable merits drug "Nemabakt" are the following:
- It is harmless to humans, domestic animals, fish, bees, beneficial insects and earthworms.
- After a single treatment of a plot of land with a drug, nematodes continue to “work” on it for several years, while they can live in the soil for up to two years even in the absence of food (insect larvae).
- Worms quickly destroy pests even at the larval stage, thus minimizing the damage they can cause to plants.
Transportation
Nematodes in packaging are in anabiosis. Therefore, the tool must be transported carefully. Extract of the drug - up to 8 hours. During this time, the nematode is already starting to move and is able to quickly penetrate the soil. At temperatures up to + 28 ° C, it should be wrapped in several layers of paper, and if the temperature rises higher, bring a cooler bag with you.
Storage conditions
Storage temperature fluctuates from 2 to 8 ° C. Bioinsecticide is best kept away from chemical poisons and insecticides. Also, do not let the light on the drug.

Application rate "Nemabakt" and instructions for use
In online stores "Nemabakt" is expensive, but the price is justified during use.
Now let's start preparing the tool for application.
First you need to dissolve the bioinsecticide. Pour water into buckets and place mosquito nets on the edges of the containers. After that, each bucket should be poured on the packaging of the drug. The temperature of the water must match the temperature of the soil and air.
You can check the readiness of the solution for use. For this you will need a magnifying glass with a 20x magnification. If the worms move, then the drug is ready. Bring "Nemabakt" in the morning or evening, on a cloudy or rainy day. The temperature should be up to 26 ° С, and the air humidity - 80% and higher.
As soon as you start "pouring" nematodes directly into the ground, remove the mesh.
When watering, try not to fall on the leaves of plants - nematodes left on the leaves will dry out and die. Half an hour after application, water the plant again. One bucket of the drug will be enough for 1 hundred parts of the land.
Important! It is better to loosen the soil beforehand, especially if the ground is very dense.
"Nemabakt" is applied to any crops where pests from the list are present, so it is worth buying and using it in your garden.
