Mode of Action of AGSO Pseudomona as a Bio-Control Agent
AGSO Pseudomonas is a multi-mechanism biological control agent that protects crops from major soil-borne and foliar fungal diseases while improving root health and plant immunity.Â
Antibiosis (Pathogen Suppression) : AGSO Pseudomonas produces natural antifungal metabolites (phenazines, pyoluteorin, DAPG) that inhibit the growth of Pythium, Rhizoctonia, Fusarium, Alternaria, Anthracnose, Cercospora, and leaf spot pathogens.
Competitive Root Colonization : It rapidly colonizes the rhizosphere and root surface, occupying infection sites and depriving pathogens of space, nutrients, and oxygen especially effective against root rot and damping-off diseases.
Siderophore Production (Iron Starvation of Pathogens) : AGSO Pseudomonas secretes strong iron-chelating compounds (siderophores), making iron unavailable to pathogenic fungi, thereby suppressing their development.
Induced Systemic Resistance (ISR) : Triggers the plant’s natural defense pathways, enhancing resistance against foliar and soil-borne diseases across the crop lifecycle.
Root Growth Promotion : Produces plant growth promoting substances that enhance root biomass, nutrient uptake, and stress tolerance resulting in healthier, more resilient crops.
Crop-wise Mode of Action
Cereal Crops (Paddy, Wheat, Maize, barley, oats, rye, sorghum and Millet) : Protects seedlings from Pythium & Rhizoctonia. Reduces root rot and sheath blight and improves root vigor and tiller strength.
Pulse Crops (lentils, chickpeas, beans (like kidney, black, navy), peas, and black gram (urad)) : Suppresses Fusarium wilt & Rhizoctonia rot. Enhances nodulation and nitrogen efficiency and Improves flowering and pod setting.
Oilseed Crops (Groundnut, Mustard, Sunflower, Soybean, Turnip rape, Linseed, Poppy) Controls collar rot, root rot, Alternaria leaf spot, and Strengthens root system and oil yield potential.
Cotton : Controls Fusarium & Rhizoctonia wilt. Enhances root health and boll retention and improves tolerance to soil stress conditions.
Sugarcane : Suppresses sett rot and root rot pathogens, Enhances early root establishment and shoot vigor.
Vegetable Crops : Solanaceous Crops (Tomato, Chilly, Capsicum, Potato) Controls damping-off, Fusarium wilt, Alternaria & leaf spot. Reduces transplant shock and enhances disease resistance and fruit quality. Cruciferous Crops (Cabbage, Cauliflower) Controls Rhizoctonia rot & leaf spot and Improves root mass and head formation. Cucurbits (Cucumber, Melon, Pumpkin, Gourds) Suppresses Pythium root rot & Anthracnose and Enhances vine growth and fruit set.
Spice Crops : (Black Pepper, Cinnamon, Cumin, Clove, Ginger, Cardamom, Chilli Pepper, Coriander, Turmeric) Controls Fusarium & Rhizoctonia rhizome rot. Reduces soil-borne disease pressure and enhances rhizome/root development.
Fruit Crops : Temperate Fruits (Apples, Pears, Peaches, Plums, Cherries, Grapes, and Berries) Controls collar rot, root rot, leaf spot diseases and enhances root health and orchard longevity.
(Sub-tropical & Tropical Fruits) (Mango, Banana, Papaya, Citrus (orange, lime), Guava, Pineapple, Jackfruit, Litchi, Pomegranate, and Avocado, alongside others such as Passion Fruit, Sapodilla (Sapota), Custard Apple, and Date Palm) Suppresses Fusarium, Anthracnose, Alternaria, Cercospora. Improves root zone microbial balance and enhances flowering, fruit retention, and quality.
Plantation Crops : (Tea, Coffee, Rubber, Coconut, Cashew, Arecanut, Cocoa, and Oil Palm) Controls root rot, collar rot, leaf spot pathogens. Enhances root resilience in perennial systems and Improves long-term soil health and productivity.
Dosage & Method of Application
Seed Treatment (Preventive Use) : Mix 1Kg of AGSO Pseudomonas with seeds required for 1 Acre (Approx25-40 Kg). Allow seeds to dry in shade before Sowing, This Provides early protection against soil pests.
Seedling Root Dip / Nursery Treatment : Mix 10 gm of AGSO Pseudomonas with 1L of water. Dip the seedling for 10-20 minutes before transplanting.
Foliar Spray (Field Crops) : Mix 1Kg AGSO Pseudomonas with 150 to 200 Liter of water for one acer. Spray thorough coverage on both leaf sides (dense spray). 10-15 day intervals.
 
Foliar Spray (Vegetables) : Mix 1Kg AGSO Pseudomonas with 150 to 200 Liter of water for one acer. Spray thorough coverage on both leaf sides (dense spray). 7-9 day intervals.
 
Soil Application (Supplementary Method) : Soil Application: Mix 2Kg of AGSO Pseudomonas with 100 Kg compost or organic manure, broadcast or apply near the root zone.
Drip Irrigation / Drenching : Mix 2Kg of AGSO Pseudomonas with 200L of water. Drip irrigation 1 acre of land.
 
Greenhouse Application: Mix 2Kg of AGSO Pseudomonas with 100 Kg compost or organic manure, broadcast or apply near the root zone.
Gardeners and small scale farmers : 10gm of AGSO Pseudomonas with 1L of water. Hand sprayer / watering can apply weekly during growing season for prevention.
Application Tips for Maximum Effectiveness
Timing: Apply early in the morning or late afternoon when temperatures are moderate.
Coverage:Â Ensure thorough coverage of all plant surfaces, especially the undersides of leaves where many pests hide.
Weather Conditions:Â Avoid application during hot, dry conditions or when rain is expected within 4-6 hours.
Early Intervention:Â Begin applications at the first sign of pest presence for preventative control.
