Benefits of Paraquat Dichloride 24% Sl
- Fastest knockdown weedicide: Visible wilting starts in 2 – 3 hours, full kill in 24 – 48 hours fastest action of any weedicide in India
- Rain-fast in 15 – 30 minutes: Best choice for monsoon spraying when sudden rain is a risk
- Wide crop approval: CIB-approved for tea, rubber, cotton, aquatic weeds, coffee, potato, apple, grapes
- Soil-safe: Binds tightly to soil on contact does not leach down, safe to plant new crop after 1 to 2 days
- Inter-crop friendly: Safe directed spray in orchards and plantations does not enter through tree bark
- Cost-effective per acre: Lower dose than glyphosate, faster results, lower per-acre cost
- Works in cool weather: Effective even in winter when glyphosate becomes slow
How Does SUMAX Work?
Paraquat is a contact herbicide it works very differently from glyphosate:
- Sprays on weed leaves: Paraquat enters the leaf surface in minutes
- Disrupts photosynthesis (PSI): Blocks the photosystem I in the plant cell
- Creates damaging free radicals: These oxygen radicals burst the leaf cells from inside
- Plant dries and dies: Wilting starts in hours, full death in 24 – 48 hours
Important: Paraquat is a contact killer only it does NOT travel to roots. Perennial weeds (Doob, Motha, Kans grass) will regrow from roots. For root-level kill on perennials, use Glyphosate 41% SL instead.
Paraquat (SUMAX) vs Glyphosate — When to Use Which? SUMAX (Paraquat) = fast knockdown in 24 – 48 hours, rain-fast in 15 minutes, best for tea, rubber, cotton pre-sowing, aquatic weeds, and inter-crop spray where you need quick visible results. Glyphosate = slow but kills roots also, best for tough perennial weeds (Motha, Doob, Kans) and pre-sowing fields where you need full root kill. Many farmers tank-mix a low dose of glyphosate + paraquat for both fast knockdown and root kill.

⭐⭐⭐⭐⭐ Technical Review: Premium Cedar Wood Glass Top Humidor (25-35 Count)
5 stars all the way! Wow! I'm speechless, but WOW! Excellent product.
This desktop humidor package is an exceptional entry-level to intermediate solution that demonstrates superior craftsmanship where it matters most: maintaining stable Relative Humidity (RH) for cigar aging and preservation. It flawlessly balances high-utility features with an elegant, display-friendly design, earning a perfect five-star rating as a standout gift or personal essential.
🔬 Technical Integrity: The Seal and The Wood
The core function of any humidor is its seal and its ability to buffer humidity changes. This unit executes both with precision:
The Airtight Seal: The box features a carefully machined lid designed with a sealed freshness coaming—a tight, internal lip that meets the box edge when closed. The result is an audible "whoosh" or vacuum sound when the lid is lifted (the "dollar bill test" typically passes with flying colors), confirming minimal air exchange. This robust seal is crucial for long-term humidity stability.
Spanish Cedar Lining: The interior is lined with genuine Spanish Cedar (Cedrela Odorata). This isn't just for aroma; cedar has a unique cell structure that is naturally hydroscopic (it absorbs and releases moisture). This acts as a humidity buffer, stabilizing the internal environment by absorbing excess moisture when RH is too high and releasing it slowly when RH drops. This buffering action is vital for consistent aging.
Capacity: The 25-35 cigar capacity (depending on cigar ring gauge) is ideal for a dedicated enthusiast or a growing collection, providing enough volume for proper air circulation without being overly bulky.
🌡️ Instrumentation and Humidification System
The integrated components simplify the critical process of humidity management.
Glass Top Display & Stability: While glass tops are sometimes criticized for being less efficient than solid wood (as wood is a better buffer than glass), this model compensates by using tempered glass that is deeply seated and sealed. This allows for visual inspection without opening the lid, a critical feature that reduces the physical disruption of the stable internal RH.
Analog Hygrometer: The included analog hygrometer is an excellent aesthetic touch. While all analog hygrometers should be calibrated immediately upon receipt, its positioning is clear and front-facing. Many users upgrade to a digital hygrometer for superior precision, but the built-in unit provides a reliable visual reference point.
Humidifier & Dropper System: The package includes a standard foam or acrylic humidifier and a dropper. This allows for precise charging with distilled water or propylene glycol solution. The inclusion of a divider helps organize the collection, ensuring proper spacing for maximum air and humidity exposure to every cigar.
🎁 Presentation and Value
The humidor's aesthetic appeal and comprehensive feature set make it a genuinely thoughtful gift.
Aesthetic Appeal: The smooth, polished exterior finish combined with the glass top makes it a beautiful piece of desk or office furniture. The overall fit and finish feel premium, with quality hinges and a solid weight.
All-Inclusive Kit: By including the box itself, the hygrometer, the humidifier, the cedar divider, and the dropper, the manufacturer provides everything needed for a new aficionado to correctly season the box and begin storage immediately.
Final Verdict: This humidor successfully executes the technical requirements of long-term cigar storage—a tight seal and Spanish cedar lining—while adding the convenience and presentation of a glass top. It is the perfect blend of form and function, offering exceptional value and performance for its class.

A Really Nice Starter or Small Humidor
This is a really nice small or starter humidor kit for someone that buys a box or small assortment of cigars and needs a place to keep them maintained while working through them over a period of time. Sized right for this need, my picture shows 20 cigars stored with plenty of room left over for 5 to 10 more.
I added my own calibrated hygrometer with the hygrometer included with the humidor. This allowed me to capture a week long stream of data showing the seasoning process of the humidor as the internal relative humidity level slowly increased as the included crystal gel humidifier added water vapor to the humidor. I did top up the humidifier with the included cigar solution over this period but very little was needed.
After a week I had a stable internal humidity level near 70% so I added 20 cigars from my well maintained collection and all is well. As long as I follow the manufacturers instructions and keep the humidor out of direct sunlight, I believe it will provide a stable long term storage environment.
Prefilled humidifier, cigar solution, travel storage tubes, dropper and instructions were all well done. One thing I'll add is the provided hygrometer can be changed from degrees C to degrees F by pushing the on-off switch twice rapidly. This is not called out in the instructions. Also, I found the provided hygrometer to be off as compared to my calibrated hygrometer. This is common and once the offset is known it can be worked around. In my case the included hygrometer was reading 4% below my test hygrometer.
Fit, finish, and build quality of the humidor was very good. It looks good on the outside and appears to be sealing very well when closed to maintain a humidified internal environment. I very much appreciate the full coverage velvet-like cushion/pad on the bottom of the humidor to keep it from scratching a softer wood surface it is placed on.
Some quick notes on the hinge and hasp hardware. The humidor includes quadrant hinges which work really well for humidors. Happy to see them included. The locking hasp does hold the lid securely closed using a ball detent locking system. Should the humidor ever become too wet or you want to let the humidor air out a bit, the hasp can be used as a lid prop to allow some outside air to enter the humidor. Added a photo of this as my description is probably lacking.
