Targeting Weed Seeds at Harvest

As herbicide-resistant weeds become more common across the country, researchers and growers are looking for other ways to control weeds.

In Colorado, they’re looking to techniques and technology developed in Australia, which has significant issues with herbicide-resistant weeds.

Known as harvest weed-seed control, these IPM-friendly methods are designed to destroy or remove weed seeds during harvest to prevent them from raining down onto the soil and replenishing the weed seed bank. In Colorado wheat, weed species of concern are winter annual grasses that share the grain’s growing cycle, like jointed goatgrass, feral rye and downy brome.

“In harvest weed-seed control, the objective is to prevent those seed-bank increases,” explained Colorado State University doctoral candidate Neeta Soni. “There are a number of ways to do it, and we’re investigating to see if they could be adopted in Colorado.”

One way to destroy the weeds seeds is by directing chaff during harvest into a cage mill – imagine a giant coffee grinder – and pulverizing the chaff and weed seeds into powder. That’s the idea behind an Australian innovation known as the Harrington Seed Destructor (and a new competitor called the Seed Terminator).

Another option is to use a piece of equipment called a chaff deck to gather chaff into mounded strips behind the harvester, capturing the weed seed in those mounds of chaff. In some places those chaff strips can be burned, and in others they’re left alone to allow the weed seeds to decay without entering the soil.

A third option is to use chaff carts and collect all the chaff and captured weed seeds for off-site destruction.

“Our research is focused on finding out if there is potential to use these methods in Colorado,” explained Soni, a graduate student of assistant professor Todd Gaines. “So what we needed to know is whether, at harvest, the majority of the winter annual grass seeds are retained in the upper wheat canopy, where they would be vulnerable to the seed destructor or other methods.”

If the weed seeds have already shattered and fallen to the soil, or if the weed seeds are below the cutting height of the combine, the methods would not be as effective.

So the Weed Research Lab team measured and counted a lot of weeds.

“What we found is that the majority of seeds are still retained at harvest,” Soni said. “Downy brome is the same height as wheat, rye is taller and jointed goatgrass a little shorter, but growers could adjust their cut height to manage it.”

Soni then counted out 1,000 seeds of each weed species into a specified amount of chaff and drove to the University of Arkansas where they have a seed destructor set up on a test platform. She ran each bundle through the destructor. The pulverized material was dusted across beds of soil to see if any weed seeds germinated. Virtually none did.

“The seed destructor was 98 percent effective on downy brome and jointed goatgrass, and 99 percent effective on feral rye,” Soni said.

The Gaines lab hopes to conduct field trials with the equipment. They will also study if the strips of mounded chaff are effective in Colorado, or if the state’s dry and windy conditions enable weed seeds to survive and spread.

The seed destructor isn’t commercially available in the United States yet, but a number of researchers are testing versions in different regions and in different crops. The initial model was a tow-behind trailer, but both Australian manufacturers now offer the technology integrated into a combine harvester that retails between $120,000 and $160,000 Australian dollars.

Not every grower would need to buy one.

“It is very common that growers here have their harvesting done by a contractor,” Soni said, “so this could be an extra service they provide.”

But not at every harvest. Because whatever specific iteration of harvest weed-seed control Colorado growers may eventually adopt, it should be just one element of an integrated management strategy, Soni cautioned.

“Repeated use could lead to the selection of earlier-shattering weed seeds, or shorter weeds,” she said. “It has to be used in rotation with other integrated measures, including herbicides and crop rotation.”

In short, it should be part of an IPM program.

Easy way to get seed out of bud

Does anyone out there known of an easy way to get seed out of buds without destroying the bud itself?

nope but I know how to get bud out of seed without destroying the buds. jkd you could google “single bud pollination” and its ways to pollinate single buds but if your new to breeding id say just fuck up the whole plant. no pain no gain

If it’s seeded by accident you either don’t sell it, hash it, or discount it. There’s no practical way to de-seed without destroying the buds. I de-seed and put the remnants into the hash/trim bin.

He didn’t say but I was assuming by the question that he accidentally seeded some bud and is trying to save it.

I seed bud all the time on purpose and when I de-seed the buds, that trim left over goes into small jars. It’s then ready to roll or stick into my pipe, bonus in my books, two-for-one

Yeah either that or the hash bin if I have more around than I can smoke/vape. I’ve seen postings about how seeded bud is not as good, lmao

New German teleporter technology makes it easy to deseed and causes zero damage to buds.

Last time I had some I pushed it through a metal pasta strainer. Got back a pile of nice seeds and a pile of bud powder lol. Worked great in the vaporizer, but I didn’t like smoking it (maybe too many hull remnants). I ended up running a bunch of QWISO with most of it and that worked out great too.

easiest way to remove it is to sell it and tell people it has seeds. let them deal with it, or poke seeds out with point of scissors.

So far I haven’t got rid of any of my smoke, so I’m just doing it as I smoke it. But when I first harvested I went through and “shucked” out what was easy to get. Then I tried to push the seeded buds to the back of the queue, so now that it’s time to plant, they are what I have left. Worked out pretty good.

If its heavily seeded it can be a pain.

I bought a real seedy ounce once (someone did the “old switcheroo” on me). was a pain in the backside .. but i smoked it.

Then put in a small hydro set up and used some of those seeds..

Honestly my out door spur d that hermied due to stress is far more potent than my indoor. I’m baffled. I was wondering if you can blow it without effecting the taste so much. Or even just edible butter

I ran this auto for seeds tossed the entire plant afterwords. With hundreds of seeds genetically matching that plant never do I try to be gentle. Besides the plants long past harvest once sacs open and seeds start falling out. To me being a month or more past harvest time makes the bud no good. Unless you prefer 90% amber mixed with disintegrated trichomes

Damn I got tricked lol 2016 read never skim

put it in a contractor bag and hang it from a tree and get a bat and hit it like a piñata. keep rearranging the stalks and shaking them after you hit it a bunch of times.

Weed Seed Destructor and Other Control Methods to Be Showcased

AMES, Iowa – Controlling weeds in farm fields is an annual challenge – especially with more weeds becoming resistant to herbicides.

Fortunately, producers have a wide range of options to counter weeds, including some creative ways that may not have been employed in the past.

At this year’s Farm Progress Show, Aug. 30-Sept. 1 in Boone, Iowa State University Extension and Outreach will showcase one of the more innovative, and practical methods of controlling weeds: a weed seed destructor.

Fitted to a combine, the weed seed destructor does what it’s name implies. It pulverizes and destroys seeds so that they cannot germinate.

The weed seed destructor (by Redekop) will be attached to the back of a John Deere 680 combine and will be available for viewing outside the ISU Extension and Outreach tent. While the machine will not be operating during the show, visitors can see it in operation on a computer screen, and they can ask questions of weed science experts.

“We want to give the public a chance to see and ask about this innovative form of weed control technology,” said Prashant Jha, professor and extension weed specialist at Iowa State. “Farmers in central Iowa and in Harrison County are already using this technology and we expect more will do so in the coming years.”

Other methods of weed control will also be featured, including videos of chaff lining, a method that guides the harvested chaff into narrow bands as it flows out the back of the combine at harvest, which reduces the spread of weed seeds by more than 95% across the fields and contains weed seeds in smaller spaces.

The harvester or combine is modified with a baffle that separates the chaff (containing the majority of weed seeds) from the straw. The chaff is directed into narrow central bands using a chute at the rear of the combine.

Weed seeds in the chaff are subjected to decay, and burial of small-seeded weed species such as waterhemp in the chaff will potentially result in reduced emergence in the subsequent growing season. High application rates of herbicides or shielded sprayers can be used to selectively control emerged weeds in those narrow bands in the field.

The weed control display will also allow visitors the chance to test their knowledge of weed specimens found in the Midwest. Sixteen different species will be available for visitors to identify.

Visitors will also have the chance to learn more about waterhemp, and how it can be suppressed using cereal rye as a cover crop. Photos and sample trays will show the results of using no rye, rye terminated at 4-6 inches tall, and rye terminated close to heading.

“We’re going to be showing the potential for biomass (cover crops) to suppress weeds like waterhemp, and how the results vary based on the height of the cover crop,” said Jha.

Cereal rye has the best potential to suppress weeds because it accumulates more biomass than other cover crop species. A study that was done for the Farm Progress Show shows an incremental decrease in waterhemp based on the density of rye.

Field studies indicate cereal rye biomass of 4,500 to 5,000 pounds per acre at termination can significantly suppress waterhemp emergence in soybeans, and reduce the size and density of waterhemp at the time of exposure to postemergence herbicides.

Additionally, producers can view a map of where herbicide resistance has been documented in Iowa based on the recent survey, and ask questions to Jha and other specialists about their own experience with herbicide-resistant weeds.

Jha will be joined at the show by ISU Extension and Outreach field agronomists Angie Rieck-Hintz, Meaghan Anderson, Gentry Sorenson and Mike Witt and several weed science graduate students.
