Krishikranti Asar Atrazine 50% WP is a selective pre-emergence and early post-emergence herbicide for maize, sugarcane, sorghum, and non-cropped areas. It controls both broadleaf weeds and annual grasses by stopping photosynthesis in target weeds. Spray within 0–3 days of sowing on moist soil to keep the crop weed-free for 45–60 days  the most critical period for maize and sugarcane yield. A trusted, low-cost alternative to Atrataf and other branded Atrazine 50% WP options.

Key Benefits of Asar Atrazine 50% WP

  • Controls 25+ broadleaf weeds and annual grasses in one spray
  • Dual action  pre-emergence and early post-emergence
  • 45–60 days residual weed control  covers the full critical period
  • Safe on maize, sugarcane, and sorghum at recommended dose
  • Cost-effective at ~₹250–₹400 per acre
  • Reduces manual weeding cost by 60–70%

How Asar Atrazine 50% WP Works

Atrazine is a Group 5 photosystem-II inhibitor. It is absorbed mainly through weed roots and partly through leaves. Once inside the weed, it binds to the D1 protein in chloroplasts and blocks photosynthesis. Weeds turn yellow, then brown, and die within 7–14 days. Crops like maize, sugarcane, and sorghum tolerate Atrazine because they break it down rapidly in their tissues.

Atrazine 50% WP Dose : Crop-Wise Recommendation

Crop Target Weeds Dose / Acre Dose / Hectare Water Volume Spray Timing
Maize Echinochloa, Digitaria, Amaranthus, Trianthema 500–800 g 1.25–2.0 kg 200 L Pre-emergence (0–3 DAS)
Sugarcane Annual grasses + broadleaf weeds 800–1600 g 2.0–4.0 kg 250 L Pre-emergence (0–3 days after planting)
Sorghum (Jowar) Annual broadleaf + grasses 500–1000 g 1.25–2.5 kg 200 L Pre-emergence (0–3 DAS)
Bajra Annual weeds 400–600 g 1.0–1.5 kg 200 L Pre-emergence (0–3 DAS)
Non-Cropped Area Mixed weed flora, Parthenium 1500–2000 g 4.0–5.0 kg 250 L Active weed growth stage

Spray Guidelines

  • Soil should be moist with a fine tilth at the time of spray
  • Use a flat fan nozzle for uniform soil coverage
  • Maintain a 4–6 hour rain-free window after application
  • Do not disturb soil for 25–30 days after spray
  • Use the lower dose on sandy/light soils; higher dose on heavy black/clay soils
  • Avoid spraying near soybean, cotton, vegetable, and pulse fields

Weeds Controlled by Atrazine 50% WP

Broadleaf Weeds

Amaranthus viridis (Chaulai), Chenopodium album (Bathua), Trianthema portulacastrum (Pathari), Portulaca oleracea (Lunia), Phyllanthus niruri, Digera arvensis, Euphorbia spp., Parthenium hysterophorus

Annual Grasses

Echinochloa colona (Sawan), Digitaria sanguinalis, Eleusine indica, Dactyloctenium aegyptium, Setaria glauca

What Atrazine Does NOT Control

Established perennial weeds and grasses beyond the 3-leaf stage are not effectively controlled. For these, use Glyphosate as a pre-sowing burn-down or tank-mix with a post-emergence partner.

Frequently Asked Questions

What is Atrazine 50% WP used for?

Atrazine 50% WP is a selective pre-emergence herbicide used to control broadleaf weeds and annual grasses in maize, sugarcane, sorghum, bajra, and non-cropped areas.

What is the dose of Atrazine 50% WP per acre?

The recommended dose is 500–800 g per acre (1.25–2.0 kg per hectare) in 200 liters of water for maize. For sugarcane use 800–1600 g per acre, for sorghum 500–1000 g per acre, and for non-cropped areas 1500–2000 g per acre.

What is the price of Atrazine 50% WP?

Current pack-wise price of Krishikranti Asar Atrazine 50% WP is listed on this page. Krishi Bhandar offers it at farm-gate rates lower than most branded options like Atrataf, with pan-India delivery and Cash on Delivery.

Is Krishikranti Asar same as Atrataf herbicide?

Both contain the same active ingredient  Atrazine 50% WP. Krishikranti Asar is a quality-tested generic equivalent of Atrataf and other branded Atrazine 50% WP products, offered at a more competitive farm-gate price.

When should I spray Atrazine 50% WP in maize?

Spray within 0–3 days of sowing on moist soil, before maize and weeds emerge. Late spraying after weed emergence reduces efficacy significantly.

Can Atrazine be used in soybean, cotton, or wheat?

No. Atrazine is NOT safe for soybean, cotton, wheat, pulses, or vegetables. It will cause severe crop damage. Use it only in maize, sugarcane, sorghum, bajra, or non-cropped areas.

How long does Atrazine stay active in the soil?

Atrazine has a long soil residual life of 3–6 months. This gives season-long weed control in maize and sugarcane, but means sensitive crops like soybean, pulses, mustard, and vegetables should not be sown for at least 3–6 months after Atrazine application.

Can Atrazine be tank-mixed with other herbicides?

Yes. In maize it is commonly tank-mixed with Pendimethalin for stronger pre-emergence control, or followed by Tembotrione 34.4% SC as a post-emergence partner for tough weeds. Always do a jar compatibility test first.

Wow!
Style: AVR-S770H
I had an Onkyo 5100 for a few years and experienced lots of issues with the UI over HDMI but after many many firmware updates they seemed to have resolved that and it had a great sound. Recently however the receiver started to turn itself on for no reason and I felt that it was a fire hazard. I bought this unit as a replacement and so far it is flawless. I believe that this receiver sounds even better and hopefully more reliable. The Atmos sound is excellent.

A firmware nightmare
Style: AVR-S770H
This piece of garbage has a mind of its own.  I bought it because I needed an HDR friendly device and it was highly recommended on more than one receiver list and went for a decent price.  In strictly audio terms it is a nice machine, though I wouldn't say its features are extensive.  However, IT decides when it wants to do things.  It randomly goes to zero volume without me touching anything (around once a week on average).  It randomly decides not to give me a picture when I turn it on.  This has improved since the last firmware update.  We are down from almost 20% of the time to slightly less than 10%.  Yes.  You read that correctly.  I have to turn it off and then on again, sometimes more than once before anything besides a brand name will show up on my TV.  It is supposed to have a screensaver but that never comes up unless they consider the stationary brand name a screen saver.  I have owned this thing for over 6 months and actually seen a screensaver with animation twice.  I have to turn my TV off if I am going to be away from it for any amount of time.  It has had plenty of opportunity.  The bottom line is that the people who write the firmware (operation software) don't seem to know what they are doing because this device is terrible at detecting REAL events and performing the necessary actions.  As a software/media developer, my primary device is a PC but I have been using PCs with receivers for decades and never had these kinds of problems.  Oh yeah... and the latest estimate of a firmware download is over 10 minutes.

Turned me into a Denon fan.
Style: AVR-S770H
I've only ever used Sony components for over 30 years. My latest Sony receiver experienced some problems. When I saw how much it would cost to repair it myself (circuit board swap), I decided to look at what else is on the market. This receiver costs less than the Sony replacement part with S&H. When the box showed up with full-sized, color pictures of the front and back of the receiver, I knew I was going to become a fan. Opened the box and one of the first thing I saw was a sheet of colored cable labels that includes labels for the components that will be plugged into the receiver. Pull the receiver out and see that the ports are color-coded too. Color-coded ports and labels is something I'm very serious about. I worked for years as a field engineer for a Fortune 100 computer equipment manufacturer. The low-end components started at $100k. For years, I tried - and repeatedly failed - to convince the product design teams to color-code the ports. To find everything I had fought for in a consumer-grade device was a dream come true. Not satisfied to make the cabling process as easy as paint-by-numbers, Denon embedded a video setup routine in the receiver that walks you through setting up your speakers, running the cables, and plugging in every single cable. The audio calibration process far exceeds what the Sony receivers do. In the box is a microphone with really long cable and a cardboard microphone stand you can easily assemble and disassemble. During the lengthy calibration, you place the microphone in 3 different listener positions - twice - for a total of 6 room readings. Adding components to each HDMI port was also just as easy and detailed. I have a small 'home theater PC' that it detected and gave me multiple names to assign to the port (Sony port names are fixed). I plugged my Xbox into the Game port and the top name on the list was Xbox. In no time, my home theater was back to normal - and I haven't even download the user manual to learn how to use the other features or go into the advanced settings.

Good with two annoyances
Style: AVR-S770H
It works for what I need (Xbox Series X FreeSync to an LG C3 TV and 5.1 speakers), but there are two annoying bugs. When it first turns on or changes to an input with a different frame rate, the content briefly flashes on the screen, then it goes black, then it goes back to the content taking a good 3 seconds before it's usable. And when you hold the volume buttons on the remote they go super slow for a bit then suddenly ridiculously fast. Not deal breakers, but it does get old after a while. Also no bi-amping, which I knew beforehand, but still a let down.

great product
Style: AVR-S770H
I bought the Denon S770H to replace my 20 year old Optimus receiver. I wasn't looking to go crazy on cost but wasn't afraid to put up a little extra money either so I chose middle of the road for Denon. When I put this in my cart I was expecting to pay $649 plus but was pleasantly surprised to see a $200 price drop by the time I pulled the trigger on the purchase. Product came quick and I set it up the next day. I am only using the 5.1 set up at this time but the way the on screen set up walks you through everything it is a breeze. The AVR analyzes each speaker position individually to optimize the settings and provides the best balances possible. This receiver takes my old speakers to a new level of enjoyment without buying anything else (at this time). Watching a Football game it makes the sound come as though you are actually in the stadium. Love it! Still haven't tried all of the options for inputs yet, but I'm sure there will not be any disappointments. I would highly recommend Denon.
