How to kill weed seeds before they get started in your fields

Adam Davis, an ecologist with USDA’s Agricultural Research Service at the University of Illinois, offers five ways to manage the weed seedbank.

As a graduate student, Adam Davis spent his Septembers crawling around on his hands and knees through crop fields trying to find and recover giant foxtail seeds for his research studies. He soon discovered that seed predators had already eaten the seeds on the soil surface. Mice, crickets, ground beetles and other organisms were doing a highly effective job at reducing the number of weed seeds.

“I began to measure weed seed predation and saw that within two days, nearly all of the seeds I’d put out in the field [to measure the amount of weed seed predation] would be gone,” says Davis, an ecologist with USDA’s Agricultural Research Service at the University of Illinois. “Over the course of a growing season, I’ve seen weed seed predators eat between 40% and 90% of the seeds produced that year. It’s an important weed management benefit that we take for granted, but which really makes a difference.”

Weed management toolbox

Davis conducted that early research to evaluate a valuable option for growers who want to manage hard-to-control weed populations: Manage the weed seedbank to prevent weeds from getting started.

The key to weed seedbank management is to reduce the ability of the seeds to germinate. Then growers either don’t have the weeds to control or they have fewer weeds to handle with other weed management tools. Here are Davis’s suggestions for managing a seedbank:

  1. Reduce seed production by either competitive crop varieties or through agronomic practices.
  2. Kill newly formed seeds by harvesting and removing weed seeds from the field with modified harvest machinery. Modified combine harvesters have been developed for removing weed seeds, and a practice known as “spray topping” uses herbicide to kill developing seed.
  3. Look at diversifying crop rotations. Crops with different growing patterns and canopy structure can also increase seed predation.
  4. Delay primary tillage. To increase weed seed predation, delay primary tillage to give predators time to eat seeds on the soil surface. Avoid deep tillage so seeds are not protected deep in the soil profile.
  5. Encourage germination of weed seeds and plan on controlling the emergence flushes completely with a stale-seedbed approach. A stale seedbed can be made through either physical (field cultivation) or chemical means. “Field cultivation is usually more effective, since it not only kills the emerged weeds, but brings new weeds to the surface to be killed in a second pass a week or two later,” Davis says.

Cover crops comeback?

Cover crops can be a tool for weed seedbank management. “Cover crops have had a long history in the Midwest, and can make a comeback should market forces and weed management realities combine to make them necessary,” Davis says. “Adding cover crops to the weed management toolkit can reduce opportunities for weed seedlings to establish, and can also provide a critical delay in weed seedling emergence so that crop competition can further suppress weeds.”

Davis says the most important element of a successful weed seedbank management strategy is to implement a diversified crop rotation so crops with contrasting life histories are grown in different phases of the rotation. “This prevents any one weed species from getting too comfortable, and makes it difficult for weeds to reproduce in the canopy of a crop with a different life history,” he says.

“We focus on killing weed seedlings because we can see them, and we have products available to do this,” Davis says. “Certainly, we don’t want to give up managing weed seedlings, but if we reduce weed seedbank population densities, managing weed seedlings becomes much easier.”

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

That’s how I do it too

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.

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.
