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: fungal culture Trichoderma harzianum VIZR-18. Manufacturer: CJSC Agrobiotechnology, Moscow. Chemical class: Bacterial fungicides and biological pesticides. Exposure rate, waiting time 3-7 days depending on conditions (temperature + humidity).
Available as tablets in a jar of 100 or a cardboard blister, two bags of 50 tablets (dried mushroom hyphae).
Mechanism of action: Fungi 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 belief, the trichoderma is not a mycorrhizal, does not form a symbiosis with the roots, it lives and develops in the soil as long as readily available carbohydrates are present in it.
Gliocladin - use
Gliocladin is used to prevent and treat pathogens of fungal diseases on garden and indoor plants. It is most effective against root rots of plants:
- alternariasis
- verticillosis
- pytiosis
- risoctoniosis
- fusariosis
- phytophthora
Gliocladin instruction
Gliocladin is used for soil preparation before sowing and planting seedlings, transplanting plants. It is not used for spraying plants. Fungi of the species Trichoderma harzianum are active only in the upper layers of the soil, where aerobic conditions are not deeper than 8 cm, with soil moisture of 60-80%, the rapid development of hyphae occurs in the temperature range 20-25 ° C, soil acidity pH from 4.5 to 6. At pH above 7, the growth of fungal mycelium is strongly inhibited.
Important: Trichoderma mushroom tablets do not dissolve in water!
Flow rates
- 1 gliocladin tablet is designed for a soil volume of 300 ml
- 3 tablets should be put on a pot with a diameter of 15-17 cm during transplantation, carefully stuck directly into the root part 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 from different sides of the root system into
- the well when planting vegetables 3-4 tablets, 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
Gliocladin - reviews
This instruction for biofungicide is not based on the manufacturer's data, but solely on the scientific and own experience of flower growers rukodelie.net/plants.
Scientists continue to study strains of plant-friendly fungi and bacteria. For example, S. Nikolaeva, A. Nikolaev, V. Shubina - scientists of 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 different effectiveness of suppressing root rot: in their in vitro experiments (in vitro) fungi Trichoderma harzianum showed antagonistic properties to a greater extent than Trichoderma chichoderma lignorum. In the petri dish, spores of phytopathogens of certain species were sown from one edge of the nutrient medium, on the other hand, Trichoderma spores.
After 7 days, the result of the interaction of antagonists could be observed. Trichoderma harzianum strains showed the most protective properties - they not only restrained the growth of the phytopathogen, but also colonized its strains by blocking and neutralizing. And Trichoderma lignorum "crushed" only phytophthora infestans. In some dishes, both species of trichoderma limited the growth of the pathogen, and pressed the harmful colonies, preventing them from growing (Alternaria alternata alternaria), but could not suppress or neutralize them in 7 days.
Trichoderma harzianum showed the best phytophthora (Phytophthora infestans), rhizoctoniosis (black scab of tubers - Rhizoctonia solani), selectively to the causative agent of fusarium - perfectly suppressed tomato fusarium (Fusarium oxysporum), but could not cope with beet fusarium (Fusarium sp.) in the allotted 7 days. Scientists explain this by the fact that the causative agent of fusariosis of beets produced antifungicidal substances that delay the growth of trichoderma fungi.
Of course, one of the experiments does not make the picture of the interaction of mushrooms reliable, and this article is not a course on microbiology. If we rely on this experience *, then all biofungicides offered on the market can behave somewhat unpredictably in the field. For example, it is logical to assume that Gliocladin (contains the Trichoderma harzianum strain) should be more effective than Trichofit (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 effectiveness to gliocladin.
According to flower growers, 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 plants experience serious stress during the use of tablets (or solution) of Gliocladin. For example, when planting tomato seedlings, hypothermia can provoke white rot, no matter how many tablets you put in the hole. Remember that the development of a mycelium capable of resisting enemies of vegetables, flowers and berries should take at least 5-7 days, while pathogens are already developing with might and main in the soil. I.e. if Gliocladin tablets haven't helped you, they may just be late, but they're not essentially useless.
It would be a mistake to put 1 tablet on a pot or pit when planting, and even to a greater depth. This is completely useless: 1 tablet is 1 seed in a mayonnaise cup. It is best to place the tablets in the upper 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 - delay the growth of Tridoderm.
Gliocladin tablets are not dissolved 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 sick 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 the trichoderma needs free water, the use of drugs based on it is advisable on constantly wet soils, and can be useful for those indoor plants that should grow in a moderately humid environment without drying, but there is a constant risk of flooding (azaleas, myrtle).
Gliocladin compatibility
The preparation is incompatible with other pesticides, except for analogues containing other Trichoderma strains (trichodermin, trichophyte, etc.). It is acceptable to use both gliocladin and Planriz, which contains Pseudomonas fluorescens, strain AR-33, since Planriz has more bactericidal effect and suppresses bacterial rot.
Gliocladin should not be diluted in water or tank mixtures. It is unacceptable to water the soil with chemical pesticides after laying tablets for 2 weeks. For example, fundazole inhibits trichoderm until it is completely destroyed.
Toxicity
Gliocladin has hazard class 4 for humans (low toxicity). Not phytotoxic. 3 hazard class for bees. It is allowed to use fishery water bodies in the zone.
Security measures
With accidental ingestion of the tablet, possible reactions: nausea, diarrhea, vomiting, allergy (urticaria), anaphylactic shock, neurotoxic reactions (depending on the number of tablets). Mandatory gastric lavage and medical advice is required.
Store the product in a dry room, optimally from + 5 to + 15 ° С, exclusively in a dry place, separate from food and medicine, in places inaccessible to children and pets. Shelf life is 2 years.
