Biological products for plant protection against various diseases

Biologics help improve plant formation and growth, increasing plant vitality, which enhances immunity. This article will tell you about the drugs that act specifically on the causative agents of various plant diseases. These drugs are based on viruses, bacteria and antagonist fungi that can stop the development of harmful bacteria. The advantage of these drugs is that they are harmless to humans and pets.

Although these drugs are safe, nevertheless, after their application, it is advisable to treat the soil with EM-solutions of your own preparation or purchased ones, such as "Baikal", "Vostok", "Shining", etc. This is necessary to restore the microflora in the soil.

Fungicidal (drugs for the prevention and treatment of diseases) biological products will help to carry out preventive treatment or stop the development of various plant diseases.

Types of biological products for plant protection

Trichodermin (Glyocladin)

Biologicals to protect garden plants from pests ✅ Summer cottage garden and vegetable garden with Hitsad

Biological products for soil and plants, unlike traditional fertilizers and protection products, do not contain chemicals. They are environmentally friendly and safe, since they are based exclusively on "live" microorganisms that increase the biological activity of soil and plants.

  • Strengthening plants
  • Boosting growth
  • Disease resistance
  • Increasing the nutritional value of products
  • Increased yield
  • Enrichment of the soil with beneficial bacteria.

We offer preparations for soaking seeds, foliar treatment of plants at various stages of vegetation. Also in our assortment are soil conditioners for restoring soil fertility.

What are biological products, and what are they?

Biological products that are used in agriculture - special means to combat plant pests, pathogens and weeds. They work on the same principle as pesticides, but differ from them in that they contain microorganisms or are made from waste products, and not made from completely synthetic compounds. Because of this, they become harmless to cultivated plants, soil, humans, insects, animals.

Depending on the origin of the active substance, preparations of biological origin are divided into bacterial, fungal and viral. The first group is used mainly to combat phytopathogens, rodents and harmful insects. Means with fungi-entopathogens are used against microorganisms that cause diseases and pests. Both plants and soil are treated with biological products. Viral biological products are produced on the basis of entomopathogenic viruses. They are specific in orientation, they act on pests of a certain type.

How is the solution prepared?

A certain amount of a biological product (ml), in accordance with the recommendations of the developer, is mixed with a small amount of water. The resulting solution is distributed in the soil and mixed thoroughly.

Here is an example of preparing a working solution from a preparation based on Trichoderma (Fungilex): preparation (100 ml) + water (1 l). The solution is distributed in a bucket of peat substrate. They do the same with bacterial and other drugs, but always taking into account the dosage recommended by the manufacturers.

Fortifying biological products based on plant extracts

This group includes funds obtained with the addition of bioactive plant extracts and capable of "working" against diseases and pests, and at the same time accelerate ripening, strengthen the immune system of horticultural crops, increase their resistance to stress and yield.
