ABTEC Pseudo is characterized by their twin properties, i.e., disease suppression and plant growth promotion. ABTEC Pseudo is antagonistic to several root pathogenic fungi, bacteria, nematodes, and several foliar fungal and bacterial pathogens. ABTEC Pseudo is available in both wettable powder and liquid formulations.
ORGANISM & COUNT : Pseudomonas fluorescens 2 × 107 cfu/g.
MODE OF ACTION :
Disease suppression: The biocontrol activity of ABTEC Pseudo is through four main mechanisms, viz., Competition, Antibiosis Mycoparasitism, and Induced Systemic Resistance (ISR). Competition refers to the substrate competition for space & nutrients. When we apply ABTEC Pseudo, around the base of the plants, it grows quickly and forms a protective cover, and prevents the entry of pathogens, thus competing for space. ABTEC Pseudo also produces certain siderophores, that have a high chelating effect with iron (Fe3+). Siderophores combine with Fe3+ ions in the soil and make it unavailable for the pathogenic fungi. Fe3+ is essential for the germination of fungal spores.
Antibiosis refers to the production of antibiotics and several secondary metabolites with antibiotic activities against soil-borne plant pathogens. Some important such metabolites are Pyocyanine, phenazine-1-carboxylic acid (PCA), Oomycin A, Pyoluteorin, 2, 4 - diacetylphloroglucinol (DAPG), HCN, and Pyrrolnitrin.
Mycoparasitism refers to the parasitization, disintegration of pathogen hyphae by secreting lytic enzymes like chitinase, proteases, lipases, and b - 1, 3 - glucanases.
ABTEC Pseudo can also suppress diseases caused by foliar pathogens by triggering a plant-mediated resistance mechanism called Induced Systemic Resistance (ISR) in plants against subsequent infection by fungal, bacterial, and viral pathogens.
Plant growth promotion: ABTEC Pseudo helps in plant growth promotion through the production of growth-promoting hormones like gibberellic acid, indole acetic acid, and naphthaline acetic acid. They promote seed germination and early flowering & fruiting.
MOST EFFECTIVE AGAINST
Highly effective against the fungal diseases caused by Phytophthora sp., Pythium sp., Sclerotium sp., Rhizoctonia sp., and Fusarium. Control of fungal diseases of rice, quick wilt and poll diseases of black pepper, foot rot and leaf spot diseases of betel vine, fungal diseases of vanilla, capsule rot and chenthal diseases of cardamom, spot rot of ginger and turmeric, different fungal and viral diseases of vegetables etc.
DOSAGE & METHOD OF APPLICATION
ABTEC Pseudo is mainly used for direct soil application, seed treatment and foliar spraying. Apply in wet soil as basal dose along with organic manure and refresh it periodically along with organic manure. The normal dosage of ABTEC Pseudo is 20g per plant.
Seed treatment: Spray the seeds with a sticky / gummy solution like starch solution or jaggery solution, so that the surface of the seed will be wet. Take ABTEC Pseudo in a tray (@ 25 g/1 kg of seeds), add the wet seeds to this and gently mix by rolling the seeds in the powder so that the seeds will be coated uniformly. Dry the seeds in shade for 30 minutes and sow within a day. For seedlings, dip the seedlings in a slurry of ABTEC Pseudo ( make a
5 - 10% slurry in sticky solution) for 5 - 10 minutes before planting.
Soil Application: ABTEC Pseudo can be used for soil application after mixing with appropriate amount of ABTEC Super Organic Manure or Farm Yard Manure @ 20kg /Ha.
Foliar Spray: Mix 1 kg ABTEC Pseudo in 50 litres of water and spray on the foliage during evening hours.
