What Diseases Does This Powder Stop?
Pseudomonas fluorescens is a friendly bacteria that fights plant disease. It works in 4 different ways at the same time. It is one of the few biologicals that stops both fungus and bacteria. And it works very well in wet, flooded, and waterlogged fields that is why paddy farmers love it.

Common Dose for All Crops
The dose is simple and works the same way across all crops. Just choose the right method based on your problem.
| Method |
Dose |
When & Why |
| Foliar Spray (on leaves) |
3–5 g per litre water
(500–1000 g per acre) |
For leaf and fruit diseases sheath blight, blast, leaf spot, anthracnose, bacterial blight |
| Seed Treatment |
10 g per kg seed |
Before sowing protects against damping off, root rot, seedling diseases |
| Soil Application |
1–2.5 kg per acre
(mix in 50–100 kg FYM) |
At sowing or transplanting for wilt and soil diseases |
| Root Dip (for seedlings) |
10 g per litre water
(dip 20–30 minutes) |
Before transplanting best for tomato, chilli, paddy, brinjal |
| Drench (for affected plants) |

OR 1–2 kg in 200 L water/acre |
When plants start drooping or showing wilt symptoms |
Quick Dose Reference: Spray: 3–5 g/L • Seed: 10 g/kg • Soil: 1–2.5 kg/acre + FYM • Root Dip: 10 g/L • Drench: 5 g/L
Step-by-Step Use
1. Foliar Spray (Most Common)
Mix 3 to 5 grams per litre of water. For knapsack pump, that means 45 to 50 grams in a 15-litre pump. Spray in early morning or late evening. Cover full plant — both upper and lower side of leaves. Repeat every 10 days during disease season.
2. Seed Treatment
Mix 10 grams per kg of seed. Add a little water, make a paste, coat seeds well, dry in shade, and sow within 24 hours.
3. Soil Application
Mix 1 to 2.5 kg per acre with 50 to 100 kg of well-rotted gobar khaad (FYM) or vermicompost. Keep mixture moist for 5 to 7 days. Then spread in field at sowing or transplanting time.
4. Drench (For Wilt & Root Rot)
Mix 5 grams per litre water. Pour around the base of plants. Or for full acre mix 1 to 2 kg in 200 litres water and drench. Repeat after 10 to 15 days if disease continues.
5. Root Dip Before Transplanting
Mix 10 grams per litre of water. Dip seedling roots for 20 to 30 minutes. Then transplant.
When to Use
- Before disease starts when weather is humid, cloudy, or rainy
- At nursery stage and before transplanting (very important for paddy, tomato, chilli)
- In fields where wilt or rot came last year
- When you see first leaf spots, sheath blight patches, or wilting plants
- Every 10 to 15 days as part of organic and IPM programs
- Right up to harvest no waiting time
Best Time for Paddy Farmers: Use Pseudomonas fluorescens at 4 stages (1) seed treatment before sowing, (2) nursery bed drench, (3) root dip before transplanting, (4) foliar spray at tillering and again at panicle initiation. This 4-stage protection is the gold standard for paddy disease management.
How Does Pseudomonas Fluorescens Work?
This friendly bacteria is smart. It does 4 things at the same time:
-
Makes natural antibiotics: Releases medicines (DAPG, pyoluteorin, phenazines) that kill disease germs
-
Steals iron from disease germs: Disease germs need iron to grow. This bacteria grabs iron first disease germs starve and die
-
Forms a protective layer: Coats roots and leaves. Disease cannot enter
-
Wakes up plant's own defence: Plant becomes stronger and fights back on its own
Bonus benefit it also acts as a plant growth promoter. Plants become greener, stronger, and produce more.
Do Not Mix With: Copper-based fungicides (copper oxychloride, copper hydroxide), streptocycline, or strong chemical fungicides. They kill the live bacteria. Keep 4 to 7 days gap before or after such chemical sprays. Safe to mix with neem oil, biofertilizers, FYM, and other organic inputs.
Why This is the #1 Choice for Paddy Farmers
-
Best biological for paddy diseases: Sheath blight, blast, bacterial leaf blight all controlled by one product
-
Works in flooded fields: Survives in waterlogged paddy where many other biologicals cannot
-
Stops bacterial diseases: Most bio fungicides cannot stop bacterial blight or bacterial wilt this one does
-
Plant growth booster: Plants become greener, stronger, and yield more
-
Zero residue: No chemical residue, no waiting time before harvest
-
One dose for all crops: Same simple dose works for paddy, tomato, banana, chilli no confusion
-
Cheap and effective: Costs much less than chemical fungicides for the same protection
-
No resistance build-up: Disease germs cannot become strong against it
-
Organic farming approved: Use it without breaking organic rules
Storage & Shelf Life
- Store in a cool, dry place away from direct sunlight
- Keep the pack tightly closed when not in use
- Best storage temperature: below 30°C
- Shelf life: 6 to 12 months from date of manufacture

Frequently Asked Questions
Q. What is Pseudomonas fluorescens powder used for? Pseudomonas fluorescens 1% WP powder is a bio fungicide. It stops paddy diseases (sheath blight, blast, bacterial leaf blight), wilt in tomato and brinjal, panama wilt in banana, root rot in pulses, and many other fungal and bacterial diseases.
Q. What is the dose of Pseudomonas fluorescens per acre? For foliar spray: 500 to 1000 grams per acre (mix 3 to 5 g per litre of water). For soil application: 1 to 2.5 kg per acre with 50 to 100 kg FYM. For seed treatment: 10 g per kg seed.
Q. How much Pseudomonas fluorescens to mix in 1 litre water? Mix 3 to 5 grams per litre of water for foliar spray. For 15-litre knapsack pump, use 45 to 50 grams. For drenching, use 5 grams per litre.
Q. Is the dose same for all crops? Yes. The basic dose is the same spray 3 to 5 g per litre, seed 10 g per kg, soil 1 to 2.5 kg per acre. Choose the application method based on your crop and disease type.
Q. Can Pseudomonas fluorescens stop sheath blight in paddy? Yes. It is one of the best biological options for sheath blight in paddy. Spray 3 to 5 g per litre of water at tillering and again at booting stage. Spray during late evening for best results.
Q. Can it stop bacterial leaf blight in rice? Yes. Pseudomonas fluorescens is one of the few biologicals that stops bacterial leaf blight in rice. Spray 3 to 5 g per litre of water at first signs of yellow streaks on leaves.
Q. Can it stop bacterial wilt in tomato? Yes. Drench around plants with 5 g per litre of water at first signs of wilting. Repeat after 10 to 15 days. Best to use as preventive — soil application before transplanting.
Q. Can it stop panama wilt in banana? Yes. Apply 50 grams per banana plant mixed with 5 to 10 kg FYM near the root zone. Repeat every 3 months. Best to start as preventive in fields with disease history.
Q. What is the difference between Pseudomonas fluorescens and Trichoderma viride? Pseudomonas is a friendly bacteria. It works on leaves, roots, and in flooded fields. It also stops bacterial diseases. Trichoderma is a friendly fungus. It works mainly in soil. Both are useful — many farmers use both together.
Q. Can I mix Pseudomonas fluorescens with chemical fungicides? No. Do not mix with copper sprays, streptocycline, or strong chemical fungicides. They kill the live bacteria. Keep 4 to 7 days gap before or after such chemical sprays.
Q. When is the best time to spray? Spray in cool hours early morning or late evening. Do not spray in strong sunlight. Start spraying before disease comes, not after the crop is already damaged.
Q. Is Pseudomonas fluorescens safe for organic farming? Yes. It is approved for organic and natural farming. Safe for soil, plants, animals, bees, and people. Zero chemical residue. No waiting time before harvest.
Q. Can it be used along with biofertilizers and neem oil? Yes. Pseudomonas fluorescens works very well with neem oil, biofertilizers, FYM, and other organic inputs. Together they give better results than alone.
Q. Does it also help in plant growth? Yes. This is a bonus benefit. Pseudomonas fluorescens also acts as a plant growth promoter. Plants become greener, stronger roots develop, and yield improves.
