It's nice to collect a good harvest of vegetables and fruits from your site, realizing that the resulting product is environmentally friendly and, of course, healthy. However, it is often necessary to fight for the harvest, first of all, with a large army of pests, various mites and insects. They are capable of not only damaging, but also destroying cultivated crops. Of course, you can “hit” this army with special chemistry, but you want to get pure products. In this case, biological products will come to the rescue. What they are and how to protect plants from pests and diseases with their help will be discussed in this article.

What it is?

Biological products are modern environmentally friendly products designed to protect plants from pests and diseases. They are based on the use of living organisms or natural biologically active compounds that these organisms synthesize. Most often they are of plant or microbiological origin.

The destruction of pests occurs through exposure to their intestines or nervous system. In the first version, eating the processed leaves, insects die from poisoning. In the second case, they are paralyzed and die of hunger. Biological preparations have a wide spectrum of action. Depending on the purpose, they are divided into the following main groups:

• biofungicides and biobactericides - drugs for fighting diseases;
• insecticides - insect repellents;
• acaricides - kill ticks;
• bioantibiotics;
• biocomplexes or stimulants - they consist of plant extracts capable of affecting the timing of growth, flowering and ripening of fruits.

Some products are effective against rodents and slugs . There are biological preparations that are used to treat seeds before planting. This operation is carried out several days before disembarkation. It is necessary to process the seeds in the shade, avoiding direct sunlight. The result will delight the grower, such planting material will be distinguished by good similarity, disease resistance, more intensive growth, and increased productivity.

Some funds are applied to the soil . It is recommended to carry out this work 5-6 days before planting the plants. In this case, the number of beneficial microorganisms in the soil increases, which inhibit pathogenic bacteria.

At the same time, the decomposition of organic matter proceeds at a faster rate, the structure of the soil improves, as a result, the productivity of crops grown on the site increases.

Before planting seedlings, it is recommended to spray its root system with special biological products. Such processing is carried out 2-3 hours before the moment of planting . Plants prepared in this way will be disease resistant and more productive. Good results can be obtained by spraying rooted seedlings with biological agents. The treatment is carried out with suspensions of different concentrations - from 0.1 to 1%. The solution must be used on the day of preparation.

During watering, you can apply the preparations together with water under the root system of plants . Bacteria of biological products will begin to interact with soil biocenosis, exerting an impact leading to a change in the development of phytophages.

This leads to the death of not only pathogenic microflora, but also insect pests.

Pros and cons

Biological preparations are convenient because their use makes it possible to obtain environmentally friendly products. The fruits processed by them can be eaten after a couple of days, without any danger to health. In addition, they do not harm the environment, killing only pests without negatively affecting beneficial participants in the biocenosis. Like any plant protection product, biological products have their pros and cons.

Advantages:

• they are safe, the composition used is absolutely harmless to humans and animals;
• environmentally friendly, since they do not pollute and do not destroy the surrounding nature, some are not dangerous for bees;
• when used correctly, they are quite effective;
• act selectively;
• they act in a complex way - most of the drugs simultaneously destroy pests and enhance the immunity of plants;
• can be used throughout the entire growing season of crops, even during flowering and ripening of fruits;
• the drugs do not cause an addictive effect in insects, which means that there is no need to constantly change them;
• it is quite economical, because a small amount of drugs is consumed on the treated area.

The disadvantages include the slow work of biological products. After all, their impact begins only after being included in the chain of biological processes. A certain difficulty is caused by storage and the need to use them immediately after preparation, they are unstable and disintegrate under the influence of sunlight.

The ecological safety of biological products is considered to be impeccable, because we are talking about the use of microorganisms isolated from biological objects of the environment and included in the circulation of substances.

Such biological preparations do not violate the natural balance, independently control the number of phytophages, pathogens and beneficial microorganisms.

Views

The first types of biological products for plant protection were developed to combat phytophages. Now these are preparations of complex action, they are able to protect plants from pests and numerous diseases.

The most popular of them are such groups

• Avermectins . These are preparations based on the toxins secreted by the fungi Streptomyces avermitilis. With their help, they fight insects, ticks and nematodes. Toxins affect the nervous system of pests. Albit is used to stimulate plant growth. You can cope with fungi and bacteria with the help of "Baktofit". The use of "Fitolavin" will help in the fight against bacterial rot. "Fitosporin - M" will help to protect the garden and vegetable garden from a complex of fungal and bacterial diseases.
• Trichoderma . To create them, the waste products of Trichoderma fungi are used. These products can be used to treat vegetative parts of plants, soak seeds and root system of seedlings, and also apply to the soil. The active substance destroys infectious diseases. In addition, the bacteria of this agent enter into symbiosis with the root system of plants, enriching them with nitrogen. To protect plants from fusarium, microsporosis, phytosporosis, anthracnose, root and gray rot, Trichoderma Veride is suitable. You can fight the causative agents of fungal diseases with the help of "Trichocin" and "Trichophlor".
• Bacterial insecticides . They are created using strains of the entomopathogenic bacteria Bacillus thuringiensis. The drug is designed to destroy pests by entering bacteria into their digestive system and damaging internal organs. To destroy lepidoptera and their caterpillars, pests of fruit and berry crops, Lepilocid is used, while Bitoxibacillin is suitable to combat ticks, lepidoptera and larvae of the Colorado potato beetle.
• Bacterial fungicides . These drugs are based on antagonistic bacteria. The active ingredient is cells with a complex of metabolites of bacteria Bacillus subtilis. They are designed to combat a variety of plant diseases. The complex preparation "Albit" is suitable as growth stimulants. To combat fungal and bacterial diseases of crops, use "Baktofit".
• Insect viruses . This category includes drugs that are deadly to pests such as Karpovirusin and Madex Twin.
• Another biological product for pests is entomopathogens of nematodes ., which use in their action the symbiosis of nematodes with pathogenic bacteria that kill pests. These include "Nemabakt"; Antonem - F.
• Biological products from plant extracts include extracts of needles, barberry, rose, ginseng . They function as fungicides and growth stimulants at the same time. Among the most popular are the drugs "Rostok", "Silk", "Fitozont".

It is recommended to use biological products in warm weather, while the air temperature should not be below 20 degrees . It is worth noting that with an increase in its effect, the drugs are doubled. A day after its application, the products become not dangerous for bees. They are dangerous for aquatic inhabitants, therefore, contact with water bodies should be avoided.

Although all biological products are not toxic to humans, however, children and pregnant women should not be allowed on the treated areas.
