Prometryn 50% SC

Prometryn 50% SC Herbicide

What It Is
Prometryn 50% SC is a selective triazine herbicide (HRAC Group 5, photosystem II inhibitor) in a suspension concentrate designed for pre-emergence and early post-directed programs. The SC system offers controlled particle size, fast re-dispersion, and low-dust, pour-ready handling.

Where It Fits
Protect the first 6–8 weeks of establishment in cotton, peanut, potato and other locally registered crops. Targets annual broadleaf weeds and suppresses certain grasses when seedbeds are clean and soil moisture is adequate.

Program Highlights

• Pre-emergence foundation with residual support to hold early flushes.

• Early post-directed passes to tidy escapes while protecting crop tissue.

• Resistance management by rotating or tank-mixing with other HRAC groups per label.

Operating Conditions

• Set rates from the local label based on soil organic matter, water hardness, and rainfall/irrigation.

• Always jar-test before new tank mixes; follow local regulations and stewardship.

OEM & Logistics
OEM private label, multilingual packaging, barcoding/QR, and COA/MSDS/TDS support available. Liquid packs: 200 L / 20 L / 10 L (bulk) and 1 L / 500 mL / 250 mL (retail); leak-resistant closures and ship-ready outer cartons.

Mode of Action — Prometryn 50% SC

How It Works
Prometryn is a photosystem II (PSII) inhibitor (HRAC Group 5) that binds to the D1 protein (QB site) and blocks electron transport in chloroplasts. Energy capture and photophosphorylation stall; sensitive weeds develop chlorosis → necrosis, leading to death. As a soil-applied residual with root and hypocotyl uptake and xylem-dominant (acropetal) translocation, it protects the germination zone during pre-emergence and supports early post-directed programs when label allows.

Selectivity & Crop Safety
Selectivity comes from differential metabolism in labeled crops and application placement. Maintain a clean, firm seedbed and avoid contacting green crop tissue when making post-directed passes. Align timing with soil moisture to activate the herbicide band in the topsoil where weeds emerge.

What Drives Performance

• Moisture activation (rainfall/irrigation) moves the herbicide into the germination layer.

• Soil organic matter/texture influence binding and residual length.

• Temperature & light affect PSII pressure and symptom speed.

• Seedbed quality (level, clod-free) improves uniform control and reduces skips.

Resistance Stewardship

• Place Prometryn (HRAC 5) in a layered program; rotate/tank-mix with different HRAC groups per label.

• Pair residual + contact strategies to manage early flushes and late escapes.

• Calibrate to the local label rate range; keep accurate records for field audits.

• Always jar-test new mixes; follow label and local regulations.

Target Weeds & Application Areas

Target Spectrum (label-dependent)
Prometryn 50% SC targets annual broadleaf weeds commonly found in row crops, with suppression of certain annual grasses depending on label and rate selection. Typical broadleaf examples include pigweeds (Amaranthus spp.), lambsquarters (Chenopodium spp.), purslane (Portulaca oleracea), chickweed (Stellaria spp.), shepherd’s-purse (Capsella bursa-pastoris), nightshade spp. (Solanum spp.), and mustard weeds (Brassicaceae). Where permitted by the local label, activity extends through the critical early-season window, reducing early flushes that undermine stand vigor and uniformity.

Crops & Use Areas (where registered)
Use in cotton, peanut, potato, and other locally registered broadacre or specialty crops to maintain clean intra-row conditions during establishment. Fit it as a pre-emergence foundation on a clean, firm seedbed, and—where labels allow—use early post-directed passes to tidy escapes while protecting green crop tissue. Programs should reflect regional agronomy: irrigation or timely rainfall for activation, seedbed preparation standards, and weed spectra typical of the target zone. Align with resistance-management plans to widen spectrum and sustain long-term efficacy.

Timing & Placement
Apply pre-emergence after planting and before crop/weed emergence to place active ingredient in the germination layer. For early post-directed use (where permitted), angle or shield spray to avoid foliage contact, targeting the soil and lower stem zone. Performance is optimized when label-guided rates consider soil organic matter/texture, anticipated weed pressure, and moisture. Clean seedbeds and consistent activation help deliver even residual bands, fewer skips, and less reliance on rescue interventions.

Application Methods & Dosage (Label-Guided)

Method & Mixing
Use standard ground sprayers with continuous agitation to keep the suspension concentrate (SC) uniformly dispersed. Fill the tank to one-third, start agitation, premix the product as a slurry if recommended by the label, then top up with water while maintaining agitation. Add only label-approved adjuvants or partners, and conduct a jar test before first-time mixes. Flush lines and nozzles after use. Avoid off-target movement; do not apply when wind or temperature inversions increase drift risk.

Rate Expression & Key Variables
Dosage must follow the local label. Rate selection typically reflects soil organic matter and texture, expected weed spectrum and density, climate/irrigation pattern for activation, and application placement (broadcast vs. banded). Where banding is allowed, calculate the band-to-broadcast conversion strictly per label guidance. Observe all use restrictions that may apply to light-textured or low-OM soils, vulnerable areas, or specific rotational crops.

Operational Safeguards
For post-directed applications, keep spray off green crop tissue to reduce phytotoxicity risk. Respect REI/PHI, PPE, and equipment hygiene requirements defined on the label. Water quality can influence outcomes—hard water and suspended solids may affect performance and compatibility—so condition water only if the label permits and local regulations allow. Document field conditions and mixes to support audits and stewardship reporting.

Formulation Stability & Packaging Options

SC Performance
Prometryn 50% SC is a suspension concentrate engineered for controlled particle-size distribution, anti-settling rheology, and rapid re-dispersion after storage. The formulation minimizes caking, supports uniform spray deposits, and maintains pour-ready, low-dust handling to reduce mixing time and operator exposure. Agitation restores homogeneity quickly, helping you hold consistent field performance across pre-emergence and early post-directed programs. Use clean water and maintain continuous agitation as directed by the label to keep the SC phase stable in the tank.

Quality Control & Shelf Life
Each batch is HPLC-released and verified through cold/heat storage and freeze–thaw cycling to protect stability during transport and seasonal swings. Routine checks cover viscosity, suspensibility, wet sieve/particle profile, and pH within release specifications, ensuring predictable handling and field results. Store in original containers under normal warehouse conditions away from direct sunlight. Shelf life: 2 years under standard storage. Always refer to local label and SDS for handling and storage instructions.

Packaging Options (OEM)
To streamline procurement, we offer OEM private label with multilingual artwork, barcoding/QR traceability, and a full COA/MSDS/TDS pack. Liquid packs cover bulk lanes (200 L / 20 L / 10 L) and retail sizes (1 L / 500 mL / 250 mL), all with leak-resistant closures and ship-ready outer cartons. Custom cartonization notes, pallet patterns, and tamper-evident seals are available to match importer and distributor requirements. Request the spec sheet and label templates to align packaging with your market’s regulations and channel strategy.

Tank Mix Compatibility & Safety

Compatibility Principles
Use Prometryn 50% SC within label-approved tank mixes to widen spectrum and support resistance management. Keep continuous agitation so the suspension concentrate stays uniform. When adding partners (residuals, contact herbicides, adjuvants), follow the label order of addition and conduct a jar test with your actual water source. Avoid mixes with products known to destabilize SC systems, and never exceed label limits on load, spray volume, or application window.

Adjuvants & Water Quality
Only use label-permitted adjuvants appropriate to the crop and timing (pre-emergence vs. post-directed). Hard water, high bicarbonates, and suspended solids can affect compatibility and performance; condition water only if permitted by the label and local regulations. Maintain clean tanks, lines, and filters; flush promptly after use to prevent residue build-up that may contaminate subsequent sprays.

Operational Safety
Respect PPE, REI/PHI, and local stewardship rules. During early post-directed applications, shield or angle the spray to avoid contact with green crop tissue. Manage drift with suitable nozzles, boom height, and wind thresholds; avoid temperature inversions. Keep spray away from non-target plants and water bodies, and follow any buffer-zone requirements.

Regulatory Compliance & Environmental Behavior

Regulatory Framework
Prometryn 50% SC is positioned as a selective triazine herbicide (HRAC Group 5). Packaging and documentation support GHS/WHMIS/REACH-aligned hazard communication. You receive a full SDS (MSDS), COA, and TDS for each batch. Storage, transport, and disposal must comply with the local label and prevailing regulations; only registered uses in the destination market are promoted and supplied.

Environmental Fate & Stewardship
Field performance and environmental profile depend on soil texture and organic matter, which influence binding and residual duration. Activation by rainfall/irrigation places the active in the germination zone; excessive runoff or leaching risks are mitigated by clean seedbeds, correct placement, and avoiding oversaturation. Protect non-target areas with setbacks and drift control. Integrate resistance management (rotate/tank-mix with different HRAC groups per label) to sustain long-term efficacy.

Rotational & Sensitive Areas
Honor all rotational crop intervals and restrictions listed on the label, especially on light-textured or low-OM soils. Follow local requirements for spray buffer zones, equipment hygiene, and container disposal/Triple-Rinse. Do not contaminate water sources during mixing, loading, or cleaning. Keep accurate application records to support audits and stewardship reporting.

Field Use Scenarios

Cotton — Pre-emergence foundation
Use Prometryn 50% SC on a clean, firm seedbed to hold early broadleaf flushes and support uniform stand. With timely rainfall/irrigation activation, rows stay cleaner through the first 6–8 weeks, reducing hand weeding and rescue passes.

Peanut — Layered residual + early post-directed
Anchor pre-emergence residual and, where label allows, follow with early post-directed passes to tidy escapes while protecting green tissue. Align rate ranges to soil organic matter and typical weed spectra for your zone.

Potato — Pre-emergence on shaped beds
Apply on well-prepared ridges so the active reaches the germination layer. Cleaner in-row conditions support even emergence and smoother early field operations; pair with complementary HRAC groups (per label) to widen spectrum.

Irrigated row crops — Activation-driven programs
Where irrigation scheduling is predictable, time applications so activation coincides with weed germination peaks. Programs built this way deliver consistent residual bands and fewer skips across the field.
