Growing a crop on a site is a good thing. But sometimes all efforts come to naught due to pests. It is necessary to constantly deal with harvest eaters, and modern means, for example, the drug N Homact, are very helpful in this .
Nematode - what is it?
Even those who are far from gardening have repeatedly heard complaints that the nematode is the culprit of many problems with the crop. From the school biology course, we can recall that nematodes are a certain class of roundworms, of which there are more than two dozen, and maybe more. These worms are parasites of plants, animals and humans. You need to get rid of them radically, because they feed on their masters. Interestingly, these parasitic worms live on land, in fresh and salt water. The largest nematode worm is found in the body of a whale, and its length reaches almost 8 and a half meters! Also, this type of worms is divided according to signs of where they live and what they eat. Plant-eating nematode worms harm plants, especially cultivated ones, for which a person cares, watered, and loosens the soil, because the larvae of these pests live and develop in the ground. But there are also nematodes that parasitize on their brethren and on the larvae of other insects. It was on this group of nematodes that scientists decided to test the ability to create a bioinsecticide. The result of such research work was the drug "Nemabact".
Plants and nematodes
For garden and garden plants, the nematode is as big a problem as this worm that lives in the body of a whale can be. If a plant is infected with a plant-eating nematode, then it develops poorly and grows. Since the parasite harms the roots, splitting them, allowing fungi and bacteria to enter. In addition, the small roots of the plants die off, and the root itself thickens, splits, becomes sick. The plant is sick and poorly fruiting. That is why nematode worms are the enemies of plants and crops in the first place. But the use of this pest is based on the Nemabakt drug, reviews of which are left by gardeners and gardeners protecting the crop.
Alien among his
So what is the drug Nemabact. Its composition can be called unusual for habitual insecticides. After all, the main component of this plant protection product is the nematode. Yes, yes, scientists have been using entomopathogenic nematode worms in their struggle with relatives for more than a decade. How so? The Nemabact preparation contains nematodes infected with a symbiotic bacterium as an active ingredient. Worms settle in the ground, there they begin to lead a normal life for themselves, but infecting their relatives, who die over time. But what are symbiotic bacteria? And this is a special kind of microorganisms that live in a single inextricable community with insect pests, worms that destroy plants. The bacterium settles in insect larvae, in bugs, worms and feeds on its host, causing its death. The nematodes themselves, which were hooked into the ground, also parasitize in the larvae of various insects living in the ground. So the drug "Nemabakt" appointment has a special purpose - without harming nature, to destroy pests.
Against whom is Nemabakt fighting?
If the plants began to feel bad in the garden, cottage area, then, of course, some parasites or diseases are to blame. It is not difficult for an experienced gardener to determine what kind of misfortune fell on his favorite beds, flower beds or a garden. If this is not a disease, then it is Nemabakt, the instructions for use, reviews of which talk about the control of insect pests, will help to cope with the problem on the site. The pests themselves, of course, will not disappear, poisoning the earth with pesticides is harming oneself and nature. Therefore, many gardeners are already using " ", expressing reviews about it mostly only positive. It is noteworthy that the Nemabact tool was developed jointly with the All-Russian Research Institute for Plant Protection, which is located in the city of Pushkin, Leningrad Region, and is produced by several Russian companies. So, the use in the fight against pests of a drug containing as an active component of entomopathogenic nematodes has a serious scientific justification. With whom is Nemabact fighting ? The reviews of those who have already used it in their beds and flower beds tell about the numerous pests that they managed to get rid of with it. The larvae of most pests develop in the ground. It is there that the entomopathogenic nematode, which contains the drug "N emebact," finds them. Instructions for use of the tool tell you what problems it helps to get rid of:
- Colorado potato beetle;
- wireworm (nutcracker beetle larvae);
- thrips (California and flower);
- cabbage scoop;
- weevil;
- mushroom mosquito;
- leaflet;
- carrot fly;
- May Khrushchev;
- bark beetle;
- a bear;
- currant glass;
- sea buckthorn fly.
There is one interesting feature behind the predatory nematode: it hibernates when it gets cold, and with the onset of heat it takes it back to work, cleansing the earth of pests and protecting the crop.
Nemabakt: for
A drug containing an entomopathogenic nematode as an active component of pest control is a unique tool among insecticides. It uses natural resources to heal nature itself, or rather a specific place where people grow vegetables, berries, fruits, flowers. The advantages of the drug "Nemabact", the instructions for which contain basic information about the tool, the following:
- the drug is absolutely harmless to living creatures - people, domestic and wild animals, bees, even aquarium fish (you never mind!) will not suffer from its action;
- bio-insecticide "Nemabact", the manufacturer guarantees this, is valid for two years, subject to the rules for using the product - that is, after treating the ground with this drug once, you can forget about the pests for two years;
- entomopathogenic nematode kills pests at the larval stage, so they do not have time to harm plants.
Manufacturers of the product announce it as a bio-insecticide that does not harm nature and all living things, helping to get rid of pest larvae in a specific area of the soil.
Nemabact: against
Before using any new remedy, you should study it well. Should you do the same when acquiring the Nemabact biological product? Instructions, reviews about it suggest several questions. For example, why do larvae of only garden pests die ? Useful soil inhabitants such as earthworms, for example, must also suffer from entomopathogenic nematodes and a symbiotic bacterium. In addition, plants on the soil surface are still unprotected from the invasion of flying, jumping and crawling pests. The answer to this question remains open, although for most gardeners and gardeners the absence of diseases on planted plants is confirmation of the effectiveness of the drug. The instruction also mentions that the bioinsecticide must be applied on time - 2 weeks before the development of the larvae, so that the nematode has time to spread throughout the site and begin its fight against pest larvae. Well, the crop should be protected from other troubles in other ways, supplementing the Nemabakt drug. Side effects of the use of bioinsecticide, we can conclude - this is a potential danger to beneficial insects, as well as inefficiency in case of lost time in the development of larvae, when they are most susceptible to the negative effects of entomopathogenic nematodes.
What's the catch?
Having decided to purchase the biological insecticide "Nemabact" for crop protection, it should be noted that the living organisms are in the package. Although they fall into a kind of suspended animation during a cold snap, they can simply dry out in a dried up substrate, and die under severe freezing. Therefore, there are features of its storage and use. Another nuance that should be considered if a decision has been made to use the Nemabact bioinsecticide is the inability to store the finished product. This is due to the fact that an aqueous solution of the preparation is prepared for introduction into the soil, during storage, the nematodes settle to the bottom, and there is no oxygen. Worms die. Therefore, it is impossible to prepare the solution in advance, as well as store it. Opened packaging with the product must be used as quickly as possible without leaving it for storage.
How to deliver?
The drug is supplied in a special soil, where entomopathogenic nematodes are in a state of suspended animation - hibernation. This effect is obtained by maintaining the storage temperature of the packages with the nematode in the range of 2-8 degrees Celsius. With increasing temperature, the nematodes begin to "come to life". It is this process that is fundamental in the transportation and preparation of biological media for use. In addition to the cold, the nematode is afraid of sunlight, ultraviolet radiation. In the sun and without moisture, it can dry. As the temperature rises during storage, the biomaterial begins to come to life, and nematodes need oxygen for life. But since the packaging is airtight, and the nematodes have gone out of the state of suspended animation with increasing temperature, they simply die without oxygen. So during transportation and storage of the bioinsecticide, the temperature regime should be strictly observed, as well as protecting the biomaterial from the vicinity of chemical insecticides and poisons.
How to use?
One of the non-chemical insecticidal drugs is Nemabact. Its use should take place strictly in accordance with the instructions. So, before use, the packaging of the drug must be deployed and the soil allowed to warm up under natural conditions, but not reaching a temperature of more than 26 degrees Celsius. Typically, biomaterial is warmed to ambient temperature in 6-8 hours. In order to verify the activity of the nematode, you should use a magnifier with an increase of not less than 20 times. Active worms should come into view, although already dead individuals are in the preparation. If the drug is active, then it is diluted with ordinary water of natural temperature in a bucket. The ratio of funds and water should be at least 1: 100, otherwise the nematode will reproduce for a very long time and there will be no effect from it. The drug is applied to the ground by spraying or watering. Do not pour water with the product so that it falls on the leaves of plants - nematodes will die in the sun or dry out in the open, and there will be no benefit from them, the money will be wasted. You can apply bioinsecticide using sprayers - mechanical or electric, but you need to remove the nets from the nozzles first so that the nematodes do not get stuck in the cells, despite their microscopic dimensions, and are not damaged by the contours of the mesh when passing through it. When applying the drug to the soil, you need to periodically shake the container with water so that the biomaterial does not settle on the bottom, but is evenly distributed. Another prerequisite for the effective use of the drug "Nemabact" is moistening and loosening the soil before adding bioinsecticide to it. This will allow nematodes to penetrate deeper faster, and besides, favorable conditions for their life will be created - moist, loose soil with active access of oxygen. You can repeat watering with a pesticide after 1 hour, and moisturize the soil to create favorable conditions for the drug to work half an hour after re-applying the product.
Is there an alternative?
Protecting plants from a variety of pests and diseases is the main task of those who grow crops, take care of forests and fields. The arsenal of agriculture and domestic gardening uses a lot of various means of helping plants. And biological products occupy their rightful place in them. Bacteria, fungi, entomopathogenic organisms such as nematodes, such as, for example, the bio-insecticide Nemabact, are used as active components of this group of products. Analogs of this drug are few. In the Russian market for such products, you can find another such drug called "Anthem-F". Many gardeners prefer to use old time-tested products such as chemical insecticides or plant-based solutions. But often such funds do not bring benefits, but can cause significant harm to the ecological condition of the site, and therefore, to the crop and people. Therefore, the use of bioinsecticides is attracting more and more attention, although for many they still cause a lot of questions and caution in use.
Summer residents of Nemabakt
The drug "Nemabakt" appeared on the shelves of Russian stores not so long ago. And among gardeners and gardeners there are many who have not yet heard about this drug. Therefore, many of those who grow flowers, vegetables, berries, fruits in their garden plots carefully study Nemabakt: instructions for use, reviews become decisive arguments in deciding whether or not to use this remedy on their plot. The statement: “How many people, so many opinions” will be natural. The same applies to the bio-insecticide "N metabact". Reviews about it are contradictory, although it should be noted that many are still happy with this tool. Most often you can hear some bewilderment about the selectivity of the drug and its absolute harmlessness to all other living creatures. For example, there are few reports that moles that resemble insects little have disappeared from the site treated with this bioinsecticide. However, thanks to this nuance, the Nemabakt product received excellent reviews , because moles also harm the crop. Many summer residents would like to increase the shelf life of the drug, complaining that it can not be stored. But nematode worms are living creatures, and it is simply impossible to program them for other living conditions. All those who have already used the bio-insecticide "Nemabact" or its analogue, "Anthem-F", are satisfied with the absence of nematode disease in plants. Although for many, the presence of other problems in obtaining a crop is a priority. But what is noted by almost all those who have already used the drug "Nemabakt" to protect plants in their country or household plots - a significant reduction in the total number of pests. And as a result, stable yields in good weather conditions.
The drug "Nemabact" reviews about itself leaves controversial, although those who are grateful to the new crop bioprotection against pests are still more than skeptics or completely dissatisfied. Biomaterial means by definition should not harm wildlife. Its action is based on natural processes that a person saw and adopted in the struggle for the crop. Of course, the fact that the active component of the preparation is living organisms brings its essential features to its use: storage and transportation conditions, the inability to procure the solution for future use, the need to maintain temperature conditions, loosening and watering the soil before applying the bioinsecticide to the soil. But these chores and worries should be rewarded by a decrease in the number of pests in the cultivated area, and therefore, an increase in yield. In addition, the drug is applied to the soil once every two years, so the chores are not so significant compared to the expected result.
