Microbiological preparation against fungal and bacterial diseases on any crops - home and garden flowers, vegetables, fruit and seedlings of berry trees and shrubs. Active ingredient: mushroom culture Trichoderma harzianum VIZR-18. Manufacturer: JSC "Agrobiotechnology", Moscow. Chemical class: Bacterial fungicides and biological pesticides. Impact speed, waiting time 3-7 days depending on conditions (temperature + humidity).

It is produced in the form of tablets in a jar of 100 pieces or in a cardboard blister, two bags of 50 tablets each (dried fungus hyphae).

Mechanism of action: Mushrooms of the genus Trichoderma harzianum either penetrate into the sclerotia of the phytopathogen fungus and slowly dissolve its cell from the inside, or wrap their hyphae around the fungal colony of the pathogen and block its further development. Contrary to some opinion, Trichoderma is not a mycorrhizal forming agent, does not form symbiosis with roots, it lives and develops in the soil as long as readily available carbohydrates are present in it.

Glyocladin - application

Glyocladin is used for the prevention and treatment of fungal pathogens on garden and indoor plants. It is most effective against root rot of plants:

  • alternaria
  • verticillosis
  • pityosis
  • rhizoctonia
  • fusarium
  • late blight

Glyocladin instruction

Glyocladin is used for soil preparation before sowing and planting seedlings, plant transplantation. It is not used for spraying plants. Mushrooms of the Trichoderma harzianum species are active only in the upper soil layers, where aerobic conditions are not deeper than 8 cm, with a soil moisture of 60-80%, the rapid development of hyphae occurs in the temperature range 20-25 ° С, soil acidity pH from 4.5 to 6 At pH above 7, the growth of mycelium of fungi is greatly inhibited.

Important: tablets with Trichoderma mushroom do not dissolve in water!

Consumption rates

  • 1 tablet of glyocladine is designed for a soil volume of 300 ml
  • on a pot with a diameter of 15-17 cm you need to put 3 tablets during transplanting, carefully stick directly into the root of the plant in the upper part of the pot
  • on a pot with a diameter of 20 cm - 4 tablets, be sure to distribute the tablets at a distance from each other on different sides of the root system
  • 3-4 tablets per hole when planting vegetables, depending on the size of the bush, as close as possible to the root system
  • when sowing seeds and when picking flower plants and vegetables (tomatoes, cucumbers) to prevent root rot, close 1 tablet to a depth of at least 1 cm

Glyocladin - reviews

Scientists continue to study strains of fungi and bacteria beneficial to plants. For example, S. Nikolaeva, A. Nikolaev, V. Shubina - scientists from the Institute of Genetics, Physiology and Plant Protection of the Academy of Sciences of Moldova, in a number of experiments, found that fungi of the genus Trichoderma of different species show the effectiveness of suppressing root rot in different ways: in their in vitro experiments (in test tube), the fungi Trichoderma harzianum exhibited more antagonistic properties than Trichoderma lignorum. In a Petri dish, spores of certain species of phytopathogens were inoculated from one end of the nutrient medium, and spores of Trichoderma, on the other hand.

After 7 days, the result of the interaction of the antagonists could be observed. The Trichoderma harzianum strains showed the most protective properties - they not only held back the growth of the phytopathogen, but also populated its strains by blocking and neutralizing. And Trichoderma lignorum "crushed" only the pathogens of phytophthora Phytophthora infestans. In some dishes, both types of trichoderma limited the growth of the pathogen, and pressed the harmful colonies, not allowing them to grow (Alternaria alternata), but could not suppress or neutralize within 7 days.

Of course, one of the experiments does not make the picture of the interaction of fungi reliable, and this article is not a term paper on microbiology. Based on this experience *, all biofungicides on the market can behave somewhat unpredictably in the field. For example, it is logical to assume that the drug Glyocladin (contains the Trichoderma harzianum strain) should be more effective than the Trichophyte drug (contains the Trichoderma lignorum strain). However, different strains of fungi of the same species show different results in suppressing root rot pathogens, therefore Trichodermin, based on several strains of Trichoderma lignorum, is not inferior in efficiency to glyocladin.

According to the gardeners' reviews, in advanced cases of the disease, for example, when plants already have signs of a black leg, biofungicides are powerless. They will not help even if the plants experience serious stress during the use of tablets (or solution) of Glyocladin. For example, when planting tomato seedlings, hypothermia can provoke a lesion with white rot, no matter how many tablets you put in the hole. Remember that the development of mycelium that can withstand the enemies of vegetables, flowers and berries should take at least 5-7 days, while pathogens are already developing in full in the soil. Those. If Glyocladin pills have not helped you, they may just be late, but not useless in fact.

It would be a mistake to put 1 tablet on a pot or pit when planting, and even at a greater depth. This is completely useless: 1 tablet is for 1 seed in a mayonnaise cup. It is best to place the tablets in the top 5-7 cm of soil, as close to the roots as possible. And remember that temperatures below 20 ° C and above 25 ° C, soil alkalinity and even neutrality, as well as soil drying - retard the growth of Tridoderma.

Glyocladin tablets do not dissolve in water, they are effective and justified only when planting, transplanting small plants, for example, when propagating strawberries, or planting seedlings, but are useless for large plants. If you have diseased large bushes, we advise you to consider treatment with other drugs, preferably in liquid form, so that you can shed the soil with high quality (Fitosporin, Trichophyte, etc.)

Since Trichoderma needs free water, the use of preparations based on it is advisable on constantly moist soils, and can be useful for those indoor plants that must grow in a moderately humid environment without overdrying, but there is always a risk of flooding (azaleas, myrtle).

Glyocladin Compatibility

The drug is incompatible with other pesticides, except for analogues containing other strains of Trichoderma (Trichodermin, Trichophyte, etc.). It is permissible to use both glyocladine and the Planriz preparation, which contains Pseudomonas fluorescens, strain AP-33, since Planriz has a more bactericidal effect, suppresses bacterial rot.

Glyocladin should not be diluted in water or tank mixtures. It is unacceptable to water the soil with chemical pesticides after laying the tablets for 2 weeks. For example, foundazol suppresses trichoderma up to complete destruction.


Glyocladin has a 4 hazard class for humans (low toxicity). Not phytotoxic. 3 class of danger for bees. Permitted to be used in the area of ​​fishery reservoirs.

Security measures

If a tablet is accidentally swallowed, possible reactions: nausea, diarrhea, vomiting, allergies (urticaria), anaphylactic shock, neurotoxic reactions (depending on the number of tablets). Requires mandatory gastric lavage and medical advice.

Store the drug in a dry room, optimally from +5 to + 15 ° C, exclusively in a dry place, separate from food and medicine, in places inaccessible to children and pets. Shelf life is 2 years.
