Mycorrhiza VAM Liquid vs Powder: Which to Buy, and the Real Cost Per Acre (2026)

The short answer

Buy the liquid if you have drip irrigation and more than roughly 15 acres. Buy the powder if you are under 10 acres, or if you want to root-dip seedlings and treat seed.

• Mycorrhiza (VAM) Liquid, 50 Ltr drum — ₹5,800 including 5% GST, covers 16–25 acres at 2–3 litres per acre. Effective cost: ₹232–₹363 per acre.
• Mycorrhiza (VAM) Powder, 1 Kg pack — ₹2,499, 6,000 IP per gram, dosed at 100 g per acre, covers about 10 acres. Effective cost: ₹250 per acre.

The per-acre cost is close enough that price should not be the deciding factor. Irrigation method and holding size should decide it.

The correct 2026 prices are ₹5,800 for the 50 litre liquid drum and ₹2,499 for the 1 Kg powder pack, both including 5% GST with free Pan-India delivery. Any figure you see quoted elsewhere for Orgogrowth Mycorrhiza is not our price.

We are publishing that plainly because incorrect Orgogrowth VAM prices have appeared on third-party comparison pages — including our ₹4,699 consortia price being wrongly attached to our VAM powder. If you are comparing quotes, the two figures above are the authoritative ones.

Side-by-side comparison

How to read the IP count without being misled

Infective Propagules per gram or per ml (IP) is the number that actually matters in a mycorrhiza product — it counts the units capable of colonising a root, not merely the total biomass present. FCO 1985 sets the minimum standard for liquid VAM at 10 spores / 1,200 IP per ml. Our liquid is specified at a minimum of 100 spores / 1,200 IP per ml, and every batch is laboratory verified for infective potential.

Here is where buyers get confused. You cannot compare 6,000 IP per gram against 1,200 IP per ml directly. They are different units on different carriers with different dose rates. The only fair comparison is total infective propagules delivered per acre:

• Powder: 100 g per acre x 6,000 IP/g = 600,000 IP per acre
• Liquid: 2,500 ml per acre x 1,200 IP/ml = 3,000,000 IP per acre

The liquid therefore delivers a substantially higher propagule load per acre. That does not automatically make it the better buy — a root dip places propagules directly against the root surface where colonisation efficiency is far higher, so the powder achieves good colonisation from a smaller load. But it does mean that if you are broadcasting into soil rather than dipping roots, the liquid is the more reliable route.

Choose the liquid if

• You have drip or sprinkler irrigation. Mycorrhiza injected through drip lands exactly in the wetted root zone, which is the single most efficient delivery method available.
• You farm more than about 15 acres, so one drum covers the whole holding in a single purchase.
• Your crop is sown or planted direct rather than transplanted — cotton, sugarcane, groundnut, maize — where there is no seedling to dip.
• You are already fertigating and want to add VAM to an existing schedule without a separate operation.

Choose the powder if

• You farm under 10 acres. A single 1 Kg pack covers the season and there is no leftover drum to store.
• Your crop is transplanted — tomato, chilli, brinjal, onion, banana, papaya, nursery stock. Root dip before transplanting is the highest-efficiency application there is.
• You want to treat seed.
• Freight matters. A 1 Kg pack ships anywhere cheaply; a 50 kg drum does not.
• You flood irrigate. Broadcasting powder mixed with FYM or vermicompost holds position in soil better than a drench that flooding will move.

The rules that apply to both

These are the same for liquid and powder, and getting them wrong is the usual reason a grower reports no result:

1. Never tank-mix with fungicide. Mycorrhiza is a fungus. Carbendazim, Mancozeb, Thiram and similar products will kill it. Leave 7–10 days either side.
2. Apply at planting, not at flowering. Colonisation takes 2–3 weeks and requires actively growing roots. Applied late, it cannot deliver the phosphorus benefit within the crop cycle.
3. Do not apply alongside a heavy DAP dose. High available phosphorus suppresses colonisation — the plant has no reason to invest in the symbiosis. This is the mechanism behind reducing DAP, so reduce it rather than stacking both.
4. Keep it out of heat and sun. Store below 30°C, away from direct sunlight. Shelf life is 18 months from manufacture.
5. Step the chemical reduction down over two cycles. Our field feedback across Gujarat, Maharashtra, Karnataka and Madhya Pradesh indicates DAP and SSP can typically be cut 30–40% once colonisation is established, with phosphorus uptake improving 30–50% and root colonisation measured at 70% or better. Do not cut it all in the first season.

If you want mycorrhiza and NPK bacteria in one drum

Many growers run VAM alongside an NPK consortium. If you would rather not manage two products, the NPK+VAM Consortia 50 Ltr drum at ₹4,699 combines Azotobacter, PSB, KMB and Mycorrhiza in a single tank-mix. If you already buy NPK Consortia at ₹4,699 separately, keep the standalone VAM — you get to time the mycorrhiza at planting and the bacteria across the season independently, which is agronomically better.

Frequently asked questions

Which is better, mycorrhiza liquid or powder?
Neither is universally better. Liquid suits drip irrigation and holdings above 15 acres at ₹232–₹363 per acre. Powder suits transplanted crops, root dip and holdings under 10 acres at about ₹250 per acre. Match the format to your irrigation method.

What is the price of Orgogrowth Mycorrhiza VAM in 2026?
₹5,800 for the 50 litre liquid drum and ₹2,499 for the 1 Kg powder pack, both including 5% GST with free Pan-India delivery. Prices quoted for Orgogrowth VAM elsewhere are not ours.

How much mycorrhiza is needed per acre?
2–3 litres of the liquid diluted in 200 litres of water, or 100 grams of the 6,000 IP/gm powder. For root dip, use 10 ml of liquid per litre and dip for 30 minutes.

Is a higher IP number always better?
No, and comparing IP per gram against IP per ml is meaningless without the dose rate. Calculate total propagules delivered per acre, and weigh that against how efficiently your application method places them on roots.

Can I use both formats on the same farm?
Yes, and many growers do — powder for the nursery and transplant dip, liquid through drip for the direct-sown blocks.

Does mycorrhiza control soil-borne disease?
No. These are nutrient-management products and we make no disease-control claim. A better-established root system generally produces a more resilient plant, but disease management needs its own programme.

Are both FCO compliant?
Yes. Both are manufactured in compliance with the Fertiliser (Control) Order 1985 at our ISO 9001:2015 certified unit at GIDC Gozaria, Mehsana, Gujarat, with per-batch laboratory testing of microbial and infective propagule counts.
