Product Name |
Pendimethalin |
|
Classification |
Herbicide / Agrochemical |
|
Formulation |
30%SC, 330g/l EC |
|
Biochemistry |
Microtubule assembly inhibition. |
|
Mode of action |
Selective herbicide, absorbed by the roots and leaves. Affected plants die shortly after germination or following emergence from the soil. |
|
Usage |
Control of most annual grasses and many annual broad-leaved weeds, at 0.6-2.4 kg/ha, in cereals, onions, leeks, garlic, fennel, maize, sorghum, rice, soya beans, peanuts, brassicas, carrots, celery, black salsify, peas, field beans, lupins, evening primrose, tulips, potatoes, cotton, hops, pome fruit, stone fruit, berry fruit (including strawberries), citrus fruit, lettuce, aubergines, capsicums, established turf, and in transplanted tomatoes, sunflowers, and tobacco. Applied pre-plant incorporated, pre-emergence, pre-transplanting, or early post-emergence. Also used for control of suckers in tobacco. |

Mammalian Toxicology |
Oral: Acute oral LD50 for rats >5000, male mice 1620, female mice 1340, rabbits >5000, beagle dogs >5000 mg/kg. |
Annual Grasses First, Broadleaf Coverage Included
Pendimethalin 330 g/L EC is a pre-emergent/early post program block for row crops and professional turf. It targets annual grasses (barnyardgrass, crabgrass, foxtails) and covers a broad set of annual broadleaves (amaranths, lambsquarters, knotweeds). As an HRAC K1 dinitroaniline, it inhibits microtubule assembly so sensitive weeds fail at germination or shortly after emergence—especially valuable in rainy seasons with staggered flushes.
Compliance note: Principle-level information only—no field rates, tank mixes, or stepwise directions. All use must follow the registered product label and local regulations.
Active Ingredient & HRAC — Dinitroaniline | HRAC K1
-
Active / Load: Pendimethalin 330 g/L.
-
Mode of Action: Microtubule assembly inhibition during mitosis → arrested cell division/elongation; uptake via roots/shoots from treated soil.
-
Selectivity: Crop safety is label-defined (metabolism/placement). Use only within labeled crop/site/timing.
Crop & Weed Fit — Annual Grasses + Broadleaf Set (label-dependent)
-
Core grasses: Echinochloa (barnyardgrass), Digitaria (crabgrass), Setaria (foxtails).
-
Broadleaves (examples): Amaranthus, Chenopodium, Polygonum groups.
-
Crops (examples): cereals, corn, soybean, cotton, rice, vegetables; confirm scope on your local registration.
-
Boundary: Not intended for perennial or advanced-stage weeds. Greatest value where grass pressure dominates; heavy broadleaf scenarios may need rotational/partner actives (per label).
Program Windows & Positioning — Preplant / Pre-em / Early Post (per label)
-
Preplant (where labeled): Surface application or shallow incorporation as a base barrier.
-
Pre-emergence: Primary window—proactive soil layer that intercepts germinating weeds.
-
Early post: Available in some crop labels; not a strength on established weeds—use program partners as allowed by the label.
Formulation & Quality Window — EC (Emulsifiable Concentrate)
-
Platform intent: Fast emulsification, reliable re-dispersion, transport/storage robustness; clear, consistent appearance with controlled odor (solvent-system dependent).
-
Quality (range-based, non-numeric): Appearance uniform; emulsifiability/re-emulsifiability passes; cold/heat storage verified; pH/viscosity within release ranges.
-
Consistency & release: RM ID check → dispersion/stability control → in-process QC (appearance, emulsifiability, stability) → batch COA release; retention samples archived; all changes under change control.
-
Safety note: ECs contain solvents—GHS hazard/precautionary statements and pictograms must align across label/SDS for the destination market; PPE and handling are label-directed.
Safety, Storage & Compliance
-
Label-first: Supply to licensed buyers only; no off-label crops/sites or extrapolated timings.
-
Storage/transport: Keep sealed in original containers; store cool, dry, well-ventilated, away from food/feed and incompatibles; ship with SDS and lane-required documents.
-
Geographic variation: Some countries/states specify buffers, sensitive-area constraints, or distinct label elements—complete a regulatory check and label alignment before commercialization.
-
Non-operational page: No field rates, mixes, or stepwise instructions are provided here.
Packaging & OEM — Multilingual Artwork, Traceability, Route-Ready
-
Pack sizes: 500 mL / 1 L (retail/professional); 5 L / 20 L (program/bulk). HDPE/PET with tamper-evident closures.
-
Labeling & traceability: Multilingual artwork (EN/ES/FR/AR/RU on request), batch ID/QR, optional anti-counterfeit (serialization/hologram).
-
Logistics kit: Drop-tested cartons; pallet patterns for 20GP/40HQ; packing list + SDS routing; shipment photo pack (filling/coding/cartoning/palletization) for intake QA.
-
Documentation: COA / SDS / TDS / label elements standard; registration support dossier under NDA on request.
FAQ
What is HRAC K1 in pendimethalin?
A dinitroaniline microtubule assembly inhibitor that stops cell division in germinating weeds.
Is pendimethalin only pre-emergent?
It is primarily pre-em, with preplant and in some markets early-post use per crop labels—always follow your local label.
Which weeds does 330 g/L EC target most reliably?
Annual grasses (barnyardgrass/crabgrass/foxtails) and common broadleaves (Amaranthus/Chenopodium/Polygonum) within labeled scope.
What documentation do you provide?
COA/SDS/TDS/label elements as standard; registration support dossier available under NDA.
