Maleic Hydrazide 80% WDG
You want onions and potatoes that stay quiet in storage, not “think it’s spring.” Maleic Hydrazide (maleic acid hydrazide) 80% WDG is a plant growth regulator you apply pre-harvest to inhibit sprouting and stabilize pack-out. It moves systemically to the meristems to suppress cell division, which means cleaner skins, fewer rejects, and less rework across your cold chain. The WDG format is fast-dispersing and low-dust, built for reliable mixing on busy harvest days. We support OEM private label, multilingual packaging, and full docs (COA/MSDS/TDS). Request spec sheet, label templates, price, and lead-time; we’ll align to your market and packaging. Always follow the product label and local regulations.
- Designed for Professional Buyers & Bulk Orders
- This product is available for business purchase and large-scale distribution.

Maleic Hydrazide
Maleic Hydrazide (Maleic Acid Hydrazide) 80% WDG is a field-applied plant growth regulator (PGR) designed for sprout suppression and regrowth control. The dust-low water-dispersible granule dissolves rapidly and is engineered for OEM shipping stability and clean handling.
How it is used (label-dependent)
Applied as a foliar treatment in the field—typically toward the late growth stage / pre-harvest window—so the active is absorbed and transported to tubers/bulbs. It is not a warehouse fumigant or in-storage spray. Follow the local product label at all times.
Where it fits
Built for potatoes and onions/shallots/garlic (where registered) to suppress sprouting across storage; also used for tobacco sucker control in specific markets. Align with your storage program (curing, temperature, humidity) to extend marketable quality.
Key Benefits
- Reliable sprout suppression for potatoes and onions (label-permitted markets), helping protect pack-out and reduce shrink during storage.
- Field-applied convenience: one standardized foliar step before harvest—no extra in-storage treatment pass.
- Consistent handling: 80% WDG disperses quickly with low dust, supporting predictable mixing and operator hygiene.
- Supply-chain readiness: OEM-friendly solid format (25 kg typical), stable for long-haul, with COA/MSDS/TDS support.
- Program compatibility: pairs with best-practice curing and cold-room management; helps reduce volunteer potatoes pressure in following crops.
- Compliance-first: label-aligned claims and documentation; clear stewardship language for audits and distributor training.
Always follow the product label and local regulations. Risk = Hazard × Exposure.
Mode of Action
Mechanism
Maleic hydrazide inhibits cell division in meristematic tissues. After foliar uptake, movement is primarily acropetal, reaching tubers/bulbs, where it suppresses sprout initiation and unwanted regrowth.
Classification note
Regulatory descriptors may list it as a plant growth regulator and, in some systems, a growth-regulating herbicide. Functionally, for potatoes and onions it is not a post-emergence weed killer; it is a sprout inhibitor used to stabilize storage quality.
Performance drivers
- Correct crop maturity and pre-harvest timing (per label).
- Adequate leaf coverage and water quality management.
- Integration with curing and storage parameters to sustain outcomes.
Target Crops & Use Cases
Potatoes — Storage sprout suppression
Use Maleic Hydrazide 80% WDG as a field-applied foliar treatment in the late growth / pre-harvest window (label-dependent) to reduce sprout initiation in storage. You protect pack-out quality, cut shrink, and stabilize inventory turnover across the storage cycle.
Onions / Shallots / Garlic — Bulb quality retention
When applied per local label, MH helps delay sprouting in bulbs, supporting grading consistency and appearance during warehousing and distribution. Align field timing with your curing plan to extend marketable life.
Tobacco — Sucker control (where registered)
In markets where labeled, MH functions as a plant growth regulator for axillary shoot (sucker) management, reducing labor pressure and keeping energy directed to target leaf development.
Note: Despite legacy references to “weed killer,” MH is not used here as a post-emergence herbicide; your primary use is sprout inhibition and growth regulation on labeled crops only.
Application Principles (Label-Guided)
- Field foliar only：This is not an in-storage fumigant or warehouse spray; apply in the field following the local label.
- Timing matters：Target the late growth / pre-harvest window at correct physiological maturity to move the active into tubers/bulbs.
- Coverage & water quality：Ensure uniform leaf coverage; manage water hardness / pH only if permitted by the label.
- Program integration：Coordinate with curing temperature, humidity, and airflow to sustain storage outcomes.
- Safety & stewardship：Observe PHI/REI, PPE, and buffer requirements; keep accurate application records for audits.
- No prescriptive rates：Dose ranges and intervals are label-specific. Conduct a small-scale check before broad adoption.
Formulation & Quality
WDG handling advantages
The 80% water-dispersible granule offers rapid wetting and dispersion, low dust, and clean measuring—ideal for OEM shipping and repeated warehouse handling. You get predictable mixing behavior that saves time at the sprayer.
Batch-level QC
Every lot is HPLC-released and verified via cold/heat storage and freeze–thaw stress to protect stability across seasons and long-haul routes. Routine checks include moisture, granule integrity, suspensibility, and particle profile to keep field performance consistent.
Storage guidance
Keep product in original packaging, off the floor, dry and away from direct sunlight. Typical shelf life: 2 years under standard conditions; always refer to the SDS/label for specifics.
