Krishikranti Bacillus Subtilis is a broad-spectrum bio fungicide that controls both foliar and soil-borne diseases powdery mildew, downy mildew, early blight, anthracnose, bacterial wilt, sheath blight, and botrytis in grapes, tomato, chilli, paddy, cotton, vegetables, and fruit crops. Used as foliar spray, seed treatment, soil application, or drenching. Residue-free and safe for organic farming.
What Krishikranti Bacillus Subtilis Controls
Bacillus subtilis is unique among bio fungicides it works on both fungal and bacterial diseases, and it can be sprayed directly on leaves, fruits, and flowers (unlike soil-only biologicals). It produces natural antibiotics (lipopeptides) that disrupt pathogen cell walls and forms a protective biofilm on plant surfaces.
Foliar Diseases Controlled
- Powdery mildew in grapes, cucurbits, mango, peas
- Downy mildew in grapes, cucumber, onion
- Early blight and late blight in tomato, potato
- Anthracnose in chilli, mango, banana
- Botrytis (gray mold) in grapes, strawberry
- Sheath blight and blast in paddy
- Scab in apple
- Sigatoka leaf spot in banana
Soil-Borne & Bacterial Diseases Controlled
- Bacterial wilt in tomato, brinjal, potato, ginger
- Bacterial leaf blight in paddy
- Fusarium wilt in cotton, banana, gram
- Damping off in vegetable nurseries
- Root rot, collar rot, stem rot
- Rhizome rot in ginger, turmeric

How to Apply Bacillus Subtilis
1. Foliar Spray
Use 2.5–5 g per litre of water. Spray during cool hours early morning or late evening. Cover both upper and lower leaf surfaces. Repeat at 7–10 day intervals during disease-favorable weather. Avoid spraying in direct sunlight.
2. Seed Treatment
Use 5–10 g per kg of seed. Make a slurry with water, coat seeds evenly, dry in shade, and sow within 24 hours.
3. Soil Application
Mix 2.5 kg per acre with 50–100 kg of well-decomposed FYM or vermicompost. Keep moist for 5–7 days, then broadcast at sowing or transplanting. Best for fields with bacterial wilt or fusarium wilt history.
4. Drenching (For Bacterial Wilt & Soil Diseases)
Dissolve 5 g per litre of water. Drench the root zone of affected and surrounding plants. Repeat after 10–15 days if disease pressure persists.
5. Seedling Root Dip
Dissolve 10 g per litre of water. Dip seedling roots for 20–30 minutes before transplanting.
Quick Dose Reference: Foliar Spray: 2.5–5 g/L • Seed: 5–10 g/kg • Soil: 2.5 kg/acre + FYM • Drench: 5 g/L • Root Dip: 10 g/L
When to Use
- Preventive: Start sprays 7–10 days before disease onset (based on weather forecast and crop history)
- At early symptoms: First spotting of mildew, leaf spot, or wilting
- During humid/cloudy weather: When fungal and bacterial diseases spread fastest
- Before flowering and fruit setting: Critical for grapes, tomato, chilli, mango
- Throughout the crop cycle: As part of IPM and organic spray programs
How It Works
Bacillus subtilis works through four mechanisms:
- Antibiotic production: Releases iturin, surfactin, and fengycin natural lipopeptides that rupture pathogen cell membranes
- Biofilm formation: Coats leaf and root surfaces, physically blocking pathogen entry
- Induced systemic resistance (ISR): Triggers the plant's own immune response
- Competition: Outcompetes pathogens for nutrients and space
Unlike Trichoderma (which is a fungus and works mostly in soil), Bacillus subtilis is a bacterium that survives well on leaf surfaces making it the go-to biological for spray-based disease management.
Compatibility Note: Do NOT mix Bacillus subtilis with copper-based fungicides (copper oxychloride, copper hydroxide), streptocycline, or strong chemical fungicides these kill the live bacteria. Maintain a gap of 7–10 days between Bacillus subtilis and any chemical bactericide or copper spray. Compatible with neem oil, biofertilizers, FYM, and most organic inputs.

Frequently Asked Questions
Q. What is Bacillus subtilis used for? Bacillus subtilis is a bio fungicide used to control both fungal and bacterial diseases in crops — including powdery mildew, downy mildew, early blight, late blight, anthracnose, bacterial wilt, sheath blight, and botrytis.
Q. What is the dose of Bacillus subtilis for foliar spray? Use 2.5–5 g per litre of water for foliar spraying, or about 500–750 g per acre depending on crop and disease pressure.
Q. Can Bacillus subtilis control powdery mildew in grapes? Yes. Bacillus subtilis is one of the most effective biological options against powdery mildew in grapes. Spray 2.5–5 g per litre of water at 7–10 day intervals during disease-favorable weather.
Q. Can Bacillus subtilis control bacterial wilt? Yes. Unlike most biological fungicides, Bacillus subtilis is effective against bacterial diseases including bacterial wilt in tomato, brinjal, potato, and ginger. Apply as soil drench at 5 g per litre of water.
Q. What is the difference between Bacillus subtilis and Trichoderma viride? Bacillus subtilis is a bacterium that works on both foliar and soil diseases and controls bacterial pathogens. Trichoderma viride is a fungus that works mainly on soil-borne fungal diseases. They complement each other many farmers use both.
Q. Can Bacillus subtilis be mixed with chemical fungicides? No. Avoid mixing with copper-based fungicides, streptocycline, or strong chemical fungicides — these kill the live bacteria. Maintain a 7–10 day gap before or after such applications.
Q. Is Bacillus subtilis safe for grapes and export crops? Yes. It is residue-free, has zero pre-harvest interval, and is approved for organic and export-grade crop production.
Q. When should Bacillus subtilis be sprayed? Spray during cool hours early morning or late evening. Avoid direct sunlight. Start preventively, 7–10 days before expected disease onset, and repeat at 7–10 day intervals.
Q. Can Bacillus subtilis be used in organic farming? Yes. It is approved for organic crop production and is widely used in IPM, integrated organic, and natural farming systems.

Very nice pull-out spice rack for square bottles. Mount with screws for permanence.
This Boivshi spice rack organizer is made with stainless steel, and has racks deep enough to keep your spice jars securely in place. There’s a thin plastic sheet for the bottom of each rack. Due to the shape of the racks, I recommend using square spice jars rather than round ones. My 6 ounce square jars fit well, and each rack holds 5 jars. Or you can use the smaller 4 ounce square spice jars and fit 6 jars in each rack. The 4 ounce jars will be looser and slide around more when you pull each rack out. I also recommend getting some round ingredient labels for your jar lids so you can identify contents quickly without having to lift each jar to look at the label. The stainless steel metal is thick, smooth and well attached, with nicely rounded corners. The top row is height adjustable. Each rack has its own extension mechanism. That means when you pull out a rack, it doesn’t pull out the entire row. This is especially important if you’ve used the adhesive to attach the rack to your pantry shelf or inside a cabinet as a top heavy item will pull and loosen the adhesive over time. The rack comes with mounting adhesive and wood mounting screws and its own screwdriver, another bonus for ease of installation. You can choose to mount the rack with the adhesive or the screws. My personal preference here is to attach this rack with the provided screws rather than the adhesive. With glass jars and weight that’s being pulled out over a tile floor in a pantry or over a hard countertop, having the risk of adhesive giving way is inviting disaster. So consider all the options when deciding on how to attach it. Overall, this Boivshi Spice Rack Organizer is very well made, and is a good deal at this price point. I definitely recommend it.

Expensive, but Smooth, Sturdy Spice Rack
I received the BOIVSHI Spice Rack Organizer through the Vine program, and overall I’m quite pleased with its quality.
The rack feels sturdy and well-made. The metal construction has a solid, heavy-duty feel, and the chrome finish gives it a clean, modern look that works well in most kitchens.
The pull-out mechanism is smooth and glides nicely. The 2-tier design is efficient and makes good use of vertical space. Installation was fairly easy and the instructions are simple enough to follow.
For me, it is limited to smaller spice bottles, due to the configuration of my cabinet which limits the available height of the top tier. Also, the rack has to be secured to the surface, either with screws or adhesive mount, to prevent it from sliding around.
Overall, it is well made and a practical solution for organizing spices. If your cabinet dimensions are compatible and you mostly use standard-size spice jars, it’s a solid upgrade that makes everyday cooking more convenient.
However, this is a very expensive spice rack, if you compare it to similar items.

Good size, looks nice, mostly easy to put together and install
Okay I love this a lot more than I expected to. I was not extremely excited about the instructions. They come with a warning that if you have any doubts about your ability to install this, call a qualified technician. It just seemed condescending. Also, everything is printed poorly, like someone put this together in the 80's and it printed smudgingly and this is the copies from that. The only thing that this made confusing was when trying to figure out where the cabinet screws go (before I realized that was an alternative install), you really can't tell which holes they go in. Turns out they probably go in the holes covered by the pre-installed sticky PVC mat.
Only other issue I had was that it comes with a screwdriver. It seems so wasteful to include something that should be in every household, especially those who buy diy things like this.
But beyond that, everything else is great. It was easy to put together, it was easy to place in the cupboard, and it was easy to fill.
I love that each line comes out individually. It's nice and sturdy. I tried pulling on it to test it, and the sticky was strong.
I mostly loved that, even though this took up 3/4 of the shelf, I was able to fit all my small spices AND my honey AND my sprinkles. I went from 3 overflowing shelves to 2 full shelves and an almost empty one. I only have 6 items on the top. I feel super happy about this.
