Greenhouse IPM Update 1.20.20

Trying to start out on the right foot with the 2020 IPM Updates.  A journey of a year starts with one week, right?


Speaking of resolutions, did you get a 2019 Census of Horticultural Specialties to fill out?  Please do as the information is very helpful to us in determining the research and education that is helpful to growers.  You can get an online copy, see FAQs and read what was found in previous surveys here.  Feb 5 is the deadline!


Bees have been used to deliver biopesticides in greenhouse crops (Flying Doctors from Biobest), but now there is researchthat suggests that beneficial mites like Swirskii and Cucumeris can deliver Beauveria bombs (an entomopathogenic fungus – say that 3 times fast) to thrips on foliage.  It isn’t a commercial product yet, but it might turn into one!


Application methods for biological controls evolve over time as we look for easier methods that maintain viability of the beneficials.  Bioline has a new blister pack system for Persimilis mites.  I’d like to see a mini drone for greenhouses (Toys, we need new toys!).


And speaking of toys, I mean, important equipment for your greenhouse – and it really is – do you know how to choose a pH/EC meter that works for you? e-GRO has an article on just that topic!


Confused about biostimulants?  I am but there is a useful new(ish) article out that explains them well.


Rutgers has a series of resistant cultivars and with the list is a lot of information on the research they are doing to make sure the resistance holds up.  They note that this resistance isn’t immunity but does delay the incidence of the disease so you need to consider an integrated system of management with good cultural practices to prevent the disease.


And here’s an E-Gro Edible Alert (do not lick your screen) on managing basil downy mildew in the greenhouse.


The sun is out and I am inspired to get out in it!  Have a great week!

Greenhouse IPM Update 1.18.17

Happy New Year!  And the information is rolling in . . . education events, webinars,  you name it.  So much that you might get 2 updates in one week!

For those in Western NY – a couple of cross the border events! (Eastern NYers can go, too – just more driving)
OMAFRA Intro to IPM Workshop in Vineland Feb 17th – Sarah Jandricic is at it again and her programs are great.

Nursery Growers Short Course Feb 15, 2017 in Burlington ON

IPM in the Woody Landscape on March 28, 2017 in Milton ON – Jen Llewllyn also puts on excellent programs

On the other side of the state- the Bedding Plant/Nursery Education Day in Voorheesville on Jan 20.

Growing calibrachoas this year?  Here’s some help – https://onfloriculture.wordpress.com/2017/01/16/managing-million-bells-2017-updates/#more-5790
Maybe Margery D. will weigh in on why some growers are getting Thielaviopsis outbreaks.  Remember that Canadian versions of pesticides may have different names – and may not be labeled in NYS.

No funny business –  The Dyson School’s Ag and Food Business Outlook is Tuesday, Jan 24 in Ithaca.  Nothing specific on the green industry – why not? – but some general information that might be helpful.

And to think we used to call it dirt!  Soil health potentially affects all aspects of plant growth.  The Institute of Soil Health has a Research Landscape Tool to find information on soil health topics.    Check it out and see what you find.

More resources from Canada – they were busy over Christmas, I guess – OMAFRA’s Guide to Greenhouse Floriculture Production – good info, remember the caveats on pesticides

Call to action!  EPA is reviewing pyrethrins and pyrethroids and is looking for grower input to know the needs for those products.  The comment period is open until Jan 30, 2017.  Even if you don’t comment, it is worth knowing about the ecological assessment and risk management rationale and which products are included.

New year – new pesticides.  Griffin has a Tech Tip out with information on new pesticides.  Orkestra is labeled for NYS – but not for Long Island, Segovis is not yet labeled for NYS, and BotaniGard MAXX is labeled for both.  Other topics, too.

Remember you can check on which pesticides are labeled for NYS at the DEC NYSPAD link .  They are improving the site, too.  Now you don’t have to scroll to the end to find the search section.

Water, water everywhere – but is it clean?  Learn a lot about water quality through the webinar series from Clean Water3

That’s it for today!  And this was what I was looking at last week – in addition to Monkey Puzzle trees in their native habitat.  Know where I was?
