Hi Guys,

Looking for a liquid chemical for residual control of weeds in paths & driveways.

Been using SIMZINE and I've had enough of using granulated chemicals.

Cheers

Simizine is a liquid chemical used to control winter grass.

Nah, its the main chemical in bantox, a residual path weeder. Been using it for a few years now on driveways etc. Even did a test on a heavily grassed vacant block and it nukes everything. Had very sparse grow back after 10 mths. Problem is it only comes granulated and no matter how well you premix in a bucket it still has residue that blocks the spray jets. That's why I need a liquid alternative.

I've never used it, but sounds like this might be what you are looking for?

We used to use this one in fish tank chemicals to control algae etc. use a mask when using it as it is very potent, used to get major headaches from it all the time.

Cheers, I'll look into it. Was at the chemical suppliers today and they reckon there was nothing else available.

Just bought a 20 litre bottle of Gesatop 600SC by Syngenta - $220. It's a Simizine powder in suspension, so it needs a stir before use. Just turn the bottle upside down a few times will do the trick appently. Supplier says Simizine is getting harder to get - Nufarm has discontinued theirs. Wish they sold these chemicals in 5 or 10 litre bottles as well.

These are basically Ag chemicals pitched at commercial/ broad-acre farm use and thus small packages are often not avail. Most farmers will be buying 100l or more of the stuff at a time.
Plus, look at the price premium you pay for any smaller package.
Some of it is due to transport cost - any size pack of most Ag chemise is treated as 'hazardous material' by transport/courier co's and you have to have it done by haz chem transporter who charge 'outrageous' prices compared to a standard courier.

A fact of the way commercial regulations are

Had a quick read of that label, says its a pre-emergent. It won't kill everything like Bantox does because bantox has glpho in it as well. Anyone tried using pre-emergent on crab grass infected areas on lawns, then topdressing and oversowing. I'd also like to use some on some garden beds to supress weed growth.

Had already planned on throwing in some glypho where needed. Will save me heaps of time in the long run, as it makes me a little grumpy having to continuously spray the same area every two weeks for weeds. 5 or 10 minutes on some of my jobs and 30 minutes on two commercials adds up real quick.

Reading the label indicates that it is compatible with / can be mixed with glyphosate, but keep it agitated, esp if left to stand fir awhile.
HOWEVER
what is of greater concern is that it suggests that it should not be used annually (or more often) in the same location to avoid the risk of development of plants that are resistant / tolerant to group C herbicides (the tri-azine family).
If we get development of resistance and these plants get into the agricultural areas, then we have a serious problem as then Simazine (& group C) herbicides are rendered useless.
Unfortunately, some of these resistances develop from uses in non farm situations.

I used it years ago on Paspalum. It did the job but also killed the surrounding Kikuyu. I only spot sprayed but I thought after it looks as if I've used roundup.

Spot spray with Di-grass, if they are juvenile it will probably knock them with one hit but if bigger they will take repeat sprays. Depending on quantity it may pay just to dig the bigger ones out.

I think there is a chance there may be rye grass in the lawn so i don't think I'd risk that one. Good point about the hand weeding, that can be the best way sometimes.

SIMZINE is not a weed killer, it's a water mobile soil steriliser. Its also supposedly carcinogenic. No way I'd even consider using it!

Water mobile = it travels in the soil with ground water/rainfall. As in, it travels under fences in the ground water into that yard next door with the kids playing in the mud.

I wouldn't want that on my conscience!

I would better describe Simazine as a pre-emegent herbicide in that it inhibits (some) plants seeds germinating/growing, but I would not agree that it is a soil sterilant.
It is true that it is 'water mobile' and in agricultural use relies on rainfall to leach it below the plant grow zone prior to growing a susceptible crop the following year.
It is used in our farming practice to inhibit weed growth in broad bean crops which are harvested as dry seed for high protein stock food. The bean seeds are sown and paddock immediately sprayed with Simazine. Bean seedling grow up through it will no ill effects, weeds do not.
I would also agree that it is not really a chemical suited for domestic/backyard use -- and I doubt if it is registered for such use. Also look at the withholding periods when grazing animals are involved --> possible residues in animal products.
Note that most 'garden vegetables' are highly susceptible to the effects of Simazine, so any residues (or movement in soil) --> veggies won't grow there.

I all cases read the label and follow the instructions.

Just found this thread while looking for Simazine suppliers. Noticed the comments about granular products being difficult to mix and clogging the sprayer... I am just about to switch to granular, was hoping that it would make it easier since I wouldn't have to buy spray dye separately as Hi-Light Blue granules already contain the dye. Then mixing it with a product like Simazine will give the same effects as if I was using Yates Path Weeder (which is not cheap to buy in 1L concentrate, and only mixes 5L of sprayable product!)

I have found another residual/pre-emergent product called Trimac, available in 1kg bag, prepackaged granules in 10x 100g packs, but it's not cheap either at $198. :eek: (100g pack mixes 100L though.)

Specialist Sales only have Simazine in 15kg bulk lots the last time I checked, not sure on price or the mix ratio but no doubt expensive and way more than I need...

Anyway - who else has used granular products? Do you still use them, would you recommend them? Or are they a bit of a hassle for mixing small quantities (5, 10, 15L)?

Using WEEDFORCE, WEED STOP, mixes fast, $150 for 500g -treats up to 5000 square metres, a tea spoon to a 15ltr sprayer.

Suggest you have a read of the label to see how apprpriate it is before jumping into this product. http://www.macspred.com.au/images/stories/pdf-attachments/Labels/trimac_industrial_label.pdf

The issues (to me) include
1. Packaging is in 100gm (100 litre mix) WATER SOLUBLE packets which are designed to be tossedin entirety into tank.
2. Product contains some sulphuron methyl (Same as Brushoff) so can have similar effects on non target plants.
3. Water mobile in soil-- they advise on leaving safety margins between sprayed areas and non target areas.
4. Withholding periods -- any sprayed vegetation not yo be grazed or used for stock food -- residues & toxicity??
5. Incompatible products - can't be mixed with Roundup Powermax or Glyphisate 540 products.

So read the label and do your research first is my honest opinion.
I suspect it's really an 'industrial' rather than domestic situation product.

I'm still using granular simazine as I gave up on the search. The chem boys here said to premix in a bucket well ahead of time to ensure full breakdown of the granules and that seems to work. You have to thoroughly wash the sprayer after. I still think the process is a PITA and would prefer a liquid, but I don't use a lot of path weeder and simazine stores easily.

. ........ You have to thoroughly wash the sprayer after.

Decontamination of equip after these chemicals is very important.
It's aways advisable to follow the label instructions for decontamination (eg if detergent, bleach etc necessary) as a simple water wash-up will often not be sufficient. Some of these herbicides will tenaciously 'stick' to plastics etc in the equipment, which water alone will not dislodge.
