Product Name: Topkill
Technical Name: Tembotrione 34.4% SC
Product Type: Insecticide
Brand Name: GSP
Product Overview:
Topkill is a selective, post-emergence herbicide containing Tembotrione 34.4% SC. It is used in maize crops to control a broad spectrum of both broadleaf and grassy weeds. It works systemically and is highly effective at low application rates.
Summary:
| Feature | Details |
|---|---|
| Mode of Action | 4-HPPD inhibitor - blocks carotenoid synthesis → chlorophyll bleaching → weed death |
| Crop | Maize (corn) |
| Target Weeds | Broad-leaf weeds and grassy weeds (e.g., Echinochloa spp., Trianthema portulacastrum, Brachiaria spp.) |
| Application Timing | Post-emergence of weeds; often when weeds are at 2-5 leaf stage (or early growth) |
| Dosage (approximate) | ~114-115 ml/acre for maize (varies by product/brand) |
| Water Volume / Acre | ~200 L per acre for spray dilution (varies) |
| Waiting Period / PHI | ~55 days (for maize) in some formulations. |
Benefits:
- Broad-spectrum control: It kills a wide variety of chewing and sucking insects that damage crops, including bollworms, fruit borers, aphids, and jassids.
- Fast action: As a neurotoxin, it acts quickly on the insect's nervous system, causing rapid paralysis and death.
- Dual action: The insecticide works through both contact (killing pests that touch the treated surface) and stomach action (killing pests that ingest treated foliage), ensuring higher efficacy.
- Higher yields: By effectively controlling pests, Topkill helps protect crops from infestation, leading to healthier plants and better yields.
- Cost-effective: Its high efficacy and broad-spectrum control mean that lower application rates can be effective, making it an economical choice for farmers.

Authentic Docs for great price!
The boots I purchased were Chelsea 2976 in Nappa leather (not the brown Crazy Horse, but the Black; such nice and soft leather!) and unisex size men's 7/women's 8/EU 39 (I'm normally a women's US 9/EU 40, but that's what fit best--see notes on sizing below).
Considering the price, I was a little skeptical that these were genuinely Dr. Marten's, so I ended up bring them into a store to verify before wearing them--and multiple salespeople, who had worked for the company for 7+ years, said they looked like the real deal to them, which is amazing for the price (I got them when they were $99 online, but $160 in store; may have been a sale...?).
Before ordering, I also visited the store to get the right sizing--Dr. Marten's doesn't sell my normal size in the US (EU 40), so I needed help figuring out what to buy. In the end that was either a women's EU 41 or a unisex 39. Dr. Marten's women's sizes are cut more narrow, so if purchasing women's, I needed a longer shoe to give my toes more space (EU 41, which they say is a women's US 9 but on many shoes EU 41 is a US 9.5 or even US 10). Unisex sizes are wider, so I was fine with a shorter length (EU 39). In the end, the only real difference between the women's sizing and men's sizing on the Chelsea boot was at the ankle; for some reason, the women's 41 had more of a gap at the ankle and I worried that might make it rub/blister more, so I went with unisex sizing. It might also depend on the boot, so I'd say go to the store for sizing before purchasing online.
Once I got them & verified their authenticity, I got a but of things to help with weatherizing them and breaking them in (Dr. Marten's has a great kit! And, double thick socks). I did get a bad blister wearing them too long & uphill on the first day (and I had to get used to their weight; I don't have many heavier shoes). But, I used Compeed patches for the blister (should have put them on to prevent, but it was fine once they were on) and after a week of wearing them a little bit at a time, they are now super comfortable and I love them! Highly recommend!

Function and style
Size: 11 Women/10 Men, Color: Black Blizzard Wp
Ideal boot for the winter, snow, mud, etc. Protect your feet beautifully, stylishly.
Tip: Wear with two socks to help break in for the first couple weeks.
If you are a half size, round up.
This is the model without laces, makes for easy slip on / slip off for those pesky people who insist on having you take off your shoes at their house! Ha ha, you know who you are.

Size up for a little bit of heel slip
Size: 9 Women/8 Men, Color: Black Nappa
It’s still a doc and the air sole with bottom out kinda quick but it’s comfortable at first. Size up for a little bit of heel slip so you don’t get heel blisters but not too big of a size jump. Think of it kind of like a cowboy boot size

Comfy, don't require "breaking in"
Size: 8 Women/7 Men, Color: Dark Brown Valor Wp
Great fit, and both my pairs of Chelsea boots required way less breaking in than other Dr. Martens I own. Hold up to frequent use and I love the fleece lining for colder days.
