are using the 47g for broccoli, cabbage, and cauliflower mostly to
combat swede midge, which was very effective last summer and has allowed
us to reintroduce those crops after several years of leaving them out.
Seems like this fabric will last quite a few years and is versatile for
other crops slots as well like cucurbits and alliums. we have used the
60g for larger bugs and critters on cucurbits and strawberries, its
heavy enough to just lay down without many sandbags and easy to peel off
is very expensive compared to remay, though i believe worth it for its
durability and effectiveness through warmer conditions.
We love it enough that is has a nick name. The crew calls it panty hose.
It is great for second crop Brassica's (June) for flea beetles.
Significant reduction in heat stress and less blowing off. Lasts two
seasons if you are careful. Some woodchuck protection as well!
I have several customers that use our ExcludeNet
netting on vegetables. They say they will never go back to using row
cover. If you like, I can ask them if they mind if I forward their
names and contact info to you. They have purchased it for several years
in a row.
University of Kentucky is doing large scale trials at growers farms
with both 60 gram and 85 gram netting. Just weeks into the trial,
growers called me to order their own netting because they liked it so
ExcludeNet netting has a five year warranty against UV degradation. I
used the 80 gram netting on my commercial blueberry planting for six
years in a row and would have used it for a seventh year had I not
gotten a SARE Grant to do a demonstration with comparing support
structures and a new method of combining pieces (zippered panels) on the
have also used the netting on my own vegetable crops both in my tunnels
and outside. I use it on greens inside my tunnels for flea beetles and
on melons outside for the myriad of pests, including deer. It’s all
netting that I got seven years ago when I started my blueberry research,
and it’s still going strong. A fabric made of the same base material
has been used in Quebec to protect baby greens from rain and hail. They
apply it and pick it up mechanically 10 times a year in Quebec and then
ship it to Florida for 10 applications per year there. It was year 12
before they started to replace the netting.
Dan Gilrein on Long Island has successfully done research with it on cabbage and was very pleased with the results.
is confusion about the difference between ProTekNet and ExcludeNet.
ProTekNet is a name that Dubois Agrinovation came up with that applies
to all of their netting products, like SUV refers to all Sport Utility
Vehicles, no matter who makes them. So you can think of ExcludeNet as a
Subaru SUV and ProTekNet as a Hyundai SUV. I don’t know where Dubois
gets their netting from now.
is manufactured by TekKnit Industries in Montreal Quebec. Dubois used
to sell the 60 gram and 80 gram netting made by TekKnit but no longer
sells the TekKnit product. After TekKnit saw what I had accomplished
with covering my commercial blueberry planting and getting virtually
zero infestation from Spotted Wing Drosophila, they asked if I would be
their Eastern U.S. Distributor. I thought long and hard about it, and
ultimately decided that my grower experience would be of benefit to
other growers in selling this product. Since then I have suggested
three innovations for the fabric to TekKnit that has resulted in a
better product for growers.

am attaching spec sheets and price lists for the 85 gram netting and 60
gram netting and an insect pest chart. I currently have 13 foot 85
gram netting in stock here in Stephentown NY and will be getting some
more 26’ 85 gram netting in a couple of weeks. More 60 gram netting is
supposed to arrive in early June.

I started using netting 4 years ago. Initially, it was
to replace ag-15 remay for salad mix covering during the summer months. I
had found that even the lightest weight remay would still trap too much
moisture, causing massive amounts of mustard rot in my greens. The
netting solved that. It kept out insects as well as shielded the greens
from rain splash, and allowed moisture to escape, thus negating the rot
Also, the netting doubles as deer
protection. Because it has no r value, it can be left on crops all
summer long, protecting them without the crops ever getting too hot or
Lastly, I have had the same rolls for 4
years. We are careful removing and rolling it as it can rip, but it is
way more durable then remay.
I think the cost is worth it.
I use proteknet for exactly the reasons you say, covering summer-planted
cucurbits and brassicas to keep them from getting too hot. I would
estimate you get at least 5 years out of it. I've been very happy with
it, because along with solving the heat problem, it is much easier to
handle. It is much lighter than regular row cover and takes up much less
space in storage. I noticed that when cutting a roll to the correct bed
length, you should give an extra buffer at the ends, because it tends
to shrink a little once you start using it. Also, once a roll of
proteknet gets ripped, I use small portions of it in the greenhouse to
cover cucurbits and other vulnerable seedlings when there is a lot of
1) What are you using it for?
Mainly to cover broccoli, chinese cabbage, baby arugula and baby kale.
2) How many years of use do you get out of it if treated well?
know it depends on which kind of proteknet you get. I have the 25g,
which I got directly from Dubois Agrinovations in QC (it's also the kind
Johnny's offers, or at least did). I've had it a couple years, and it's
still doing well, although if it snags (jagged fingernails can be a
culprit) it'll develop a few small runs like a nylon stocking, but it
doesn't really seem to hurt it's effectiveness since it didn't actually
break the weave. I use sandbags to weigh it down, not ground staples or
anything that would shred it. Not sure about how well it would last when
edges are buried with dirt to weigh it down. The 25g is pretty thin and
stretchy, making it easy to work with and it excludes even the little
bugs, but it's not the longest lasting of the options ( I think they
rate it at 3 years ish?). I know of another farm that has a stiffer,
thicker version of proteknet that looks like it would last a really long
time, but is less see-through and less stretchy.
3) Do you notice a significant difference in quality of crop when using proteknet vs 0.5oz row cover?
The plants, especially the chinese cabbage and arugula seemed a lot less heat stressed
4) Anything else of note?
definitely pricy, but I like that it lasts multiple years. I'm pretty
small-scale, but for me, it was definitely worth it. I also really like
that it's so see-through. This is one of those things that is more
important than I thought--the out of sight, out of mind thing is really
big. Seeing through it helps me consistently assess the crop, consider
harvest time, weeds, etc (especially helpful for quick turnover baby
arugula and kale beds that need a constant eye but also need flea beetle
protection)--so much easier than with agribon/remay/covertan row cover.
I trialed sewing some cheap black landscape fabric strips along the
edges so that the landscape fabric touches the ground and is weighed
down by the bags, so the proteknet doesn't touch the ground and
deteriorate. Went pretty quickly with a simple sewing machine. Trial is
still out on whether that significantly increases the lifespan long
enough to be worth the effort, but it has worked really well so far. I
can't imagine sewing it during the spring rush though, that was
something I did during the quieter winter months, and only on a small,
