Greenhouse IPM Update 6.20.16

Happy summer solstice!  I was picking strawberries at 9:00 last night to celebrate (or just because that’s finally when I got around to it!)

Hot enough for you?  Thrips biocontrol agents are also affected by temperature.  Michigan State notes that the predatory mite Neoseiulus cucumeris isn’t as tolerant of temperatures over 75 F as is Amblyseius swirskii.  And Steinernema nematodes should be applied later in the evening as they prefer median temperatures between 50 and 80 F.  Orius, however, likes it hot!

New and used – well, previous.  Ball Publishing’s webinar series.  New – June 21 on Mites in the Nursery. Archived – Root rot management for annual and perennial crops http://www.ballpublishing.com/BallPub/_Webinars.aspx

Are you hungry?  How about your plants?  A Nutrient Deficiency Refresher from Chevonne Carlow at OMAFRA   Hmmm, I think I’ll eat lunch!

It just looks like dirt and water.  It is really a whole series of methods for testing your growing media from Premier Tech. http://www.floraldaily.com/article/5506/How-to-test-growing-media  And since you just learned about nutrient deficiencies, you should try it now!

Need new toys?  Insect-dropping ‘eco-drones’ for dispersing biocontrols

How about new crops?  Michigan State is holding a tour of fruit production under high tunnels on July 5, 2016. Cornell has raspberries in high tunnels but cherries?

 

Stay cool and have a great week!

Greenhouse IPM Update 1.17.16

How the email piles up!  But lots of good stuff in there, even if I think of just deleting them all and starting over.  Is that Spring Cleaning?

Webinars for everyone – from E–GRO
January 22 – Managing Nutrient Solutions for Hydroponic Leafy Greens and Herbs is full but contact Brian Whipker for more information: bwhipker@ncsu.edu

January 29, 11-2 Eastern time – PGR University: Cutting Edge PGR Webinar https://attendee.gototraining.com/r/4737168154709094146
February 5 – 2–3 Eastern time – Blisters, Bumps and Lesions: What we know about the physiological disorders of intumescence and edema

There is much more to find at the e-GRO website –  Videos, research, alerts . . .

Want your education face to face? Plant Nutrition for Greenhouse Crops: On-site Media Testing, Feb 16, Sturbridge MA.  Click here for more information
How nice!  Handouts and information from previous events are all collected in one site,   And note the buttons for Fact Sheets, Publications and Resources, etc.

Got drips running down the back of your neck when you are in the greenhouse?  Here’s the article for you. Reducing Humidity in the Greenhouse

And that relates to botrytis and how to manage it!

Moisture levels even matter in space!

Ten ‘easy’ steps to greenhouse sanitation – NOW is the time to do it if you haven’t already.

And something else to clean in case you didn’t do it yet – how to winterize your sprayer – even if winter doesn’t really happen in your greenhouse

There may be no such thing as a free lunch but MSU has FREE Pest Scouting Bulletins to download – including Greenhouse.

And one on Commercially Available Biological Control Agents for Common Greenhouse Insect Pests!

Really being prepared!  Northeast Greenhouse Conference and Expo – November 9-10 in Boxborough, MA.

Keeping hydroponic roots happy!  Temperature, oxygen levels and beneficial microbes at optimum levels helps.

Stay warm and cuddled up to your computer watching webinars!  Have a great week!  Maybe even get out to one of the many greenhouse educational meetings this month!

Wow, suddenly it seems like there is a lot of new information out there.  So I will send it all to you – maybe not ALL . . . I don’t want anyone’s head to explode.

Get out the popcorn, again.  Plant Nutrition Research archived webinars are available from e-GRO!
Why basic fertilizers drop your substrate pH 
Revising your phosphorus fertilization strategy 
Vermicompost usage as an organic fertilizer (You go, Stephanie!)
Silicon fertilizer enhances stress tolerance of bedding and potted plants (Our own Neil Mattson)

What’s in your pesticide storage?  And do you know how cold weather affects it? MSU information on winter storage of pesticides.
And a reference from Wyoming.

Juggling temperature and light and CO2 for optimum growth – not easy. But here is a nice description of how it all works.  (You must watch out for us plant physiology geeks!)

Laser ablation electrospray ionization mass spectrometry imaging – uh, huh! It is actually using a laser to boil the contents of a cell until it explodes then analyzing the mist produced. Why? So you can determine the differences on a cell to cell basis – perhaps mapping plant metabolites that affect how plants react to insects and diseases.  Cool but practical?

Just ‘cause they are cute.  A new pink hanging basket tomatoRambling Rose

I was supposed to be in Canada but I am enjoying pretending I have 2 ‘free’ days and the weather is lovely (that’s not pretense)!

Have a great week!

Still here – although the gardens beckon!

Basil downy mildew has been reported in several locations around the state and the region and your customers might be seeing it in their gardens. Some resources to pass along: From Meg McGrath on Long IslandFrom Tina Smith and the NE Greenhouse Update.

Keep an eye on those chrysanthemums – it’s getting to be that time again. And not just for chrysanthemum white rust.  Chrysanthemums can get tomato spotted wilt virus, too – another reason for yellow blotches and brown spots. Information from MSU.

What’s it worth to ya?  Greenhouse Canada has a nice article on ‘Investing in Lab Analysis’.

Feeling the pressure? I remember learning about vapor pressure deficit long ago but why should you care?  It is a better way of determining if your plants are transpiring and likely to dry out than relative humidity is. Learn why.  Do I have to do math? Nope – here’s a handy chart!
Back to school – just like a kid with a too short summer vacation I don’t want to think about it.  But if you or your staff need some training, here are some options.
On-line courses from Back Pocket Grower from the University of Florida
Webinars, including ‘Growing Bee- Friendly Plants in the Greenhouse’ and ‘Top Diseases and Insects in Nursery Crops’, from Michigan State University
On-line courses with pesticide recertification credits for several states from PMEP and NYS IPM

I like bugs and I think this is scary disgusting . . .   On the other hand you could kill a lot with the IPM practice of stomping on them.

I hope you are all resting on your laurels from spring and summer at least a little bit AND that I will see you next week at the Floriculture Field Day!

Seems like I have been driving around the state a lot lately.  And talking or listening to talks about pollinators.

Mark Adams rocked the Pollinator Conference  last Tuesday!  Give him a microphone headset  . . . . .  He talked about Adams Greenhouses decisions to go neonic free.  And Dan Gilrein joined in with great data on pesticide alternatives that are safer for bees.  As soon as we have the video available, I’ll let you know so you can see what you missed!  (I even live tweeted the event!  I KNOW, I’m so modern!)

The State Task Force on Pollinators is working on a Pollinator Protection Plan as encouraged by the EPA.  It’s worth paying attention as what they decide may affect your production methods.  I’ll keep you posted on what I hear (NYS IPM’s Jennifer Grant is on the task force).
I received an excellent comment on Chrysanthemum white rust – which is really applicable to all pests.  Get ‘free’ scouting from your staff by showing them what the disease looks like – post pictures, for example (and let me know if you need some!).   And for this and other issues that are easily spread – ask them to take you to the affected plants rather than having staff carry them through the greenhouse to show you.  Remember we are always trying to find the first insect or lesion or whatever – and more eyes help!

LOTS of educational opportunities out there
