Oops – what happened to Friday? I started this email but it got lost in a crazy afternoon.  And the weather went crazy, too.

May 10                 May 15

Champlain                           23                           29

Geneva                                45                           55                           10 degree increase from what was expected for the 13^th so we

must be getting warm again (hooray!)

Riverhead (LIHREC)         108                         125                         Some of this big bump is that the Riverhead LIHREC station is

back on line and they are warmer than the MCV station.  Since this is one of the warmest stations in NYS, I’ll stick with LIHREC unless they go offline again!

I’ve heard a little about bud break starting.  What species are breaking bud where you are and do you think you had cold temperature damage to any buds?

Have a great week!

I’ll start with the very annoying news because you can perhaps do something about it – Freeze warning for parts of NYS – and snow.  What you might be able to do is bring plants in.  Unfortunately there are a lot of buds out there at prime time for frost of freeze damage.

The good news – The Small Business Administration’s EIDL loans are prioritizing agriculture.  If you haven’t applied (and you meet the criteria), do!  https://www.sba.gov/page/disaster-loan-applications

The bad news –  like much of officialdom there are rules and they aren’t always clear.  The Paycheck Protection Program funds have rules that must be followed to change them from loans to grants.  Make sure you understand how the money must be spent to get it as a grant.  Check with your bank.

The loan will be fully forgiven if the funds are used for payroll costs, interest on mortgages, rent, and utilities (due to likely high subscription, at least 75% of the forgiven amount must have been used for payroll). Loan payments will also be deferred for six months. No collateral or personal guarantees are required. Neither the government nor lenders will charge small businesses any fees.

Forgiveness is based on the employer maintaining or quickly rehiring employees and maintaining salary levels. Forgiveness will be reduced if full-time headcount declines, or if salaries and wages decrease.https://www.sba.gov/funding-programs/loans/coronavirus-relief-options/paycheck-protection-program#section-header-2

Keep on doing your usual good work!  I am always impressed by NYS’s ornamental producers!

I’m not so lazy this week! And some of this is even IPM!

Ever heard of Tulip Fire?  It’s botrytis and it is doing a number on some tulips this spring. (see attached picture)

Lily Leaf Beetle are out already – so I have heard from Trumansburg. Are they wearing little wooly long underwear?

Lilioceris lilii adults overwinter in sheltered places. As soon as susceptible hosts such as Lilium spp. (Turk’s cap, tiger, Easter, Asiatic, and Oriental lilies) and Fritillaria spp. break through the ground, the adult lily leaf beetles are known to feed on the new foliage. (Note: daylilies are not hosts.) Typically, in May, mating will occur and each female will begin to lay 250-450 eggs in neat rows on the underside of the foliage. If there are only a few plants in the garden, hand picking and destroying overwintering adults can help reduce local garden-level populations at this time. For more information about this insect, visit the newly updated fact sheet: https://ag.umass.edu/landscape/fact-sheets/lily-leaf-beetle .

Want to learn more about lily leaf beetle’s life cycle and learn to recognize adults, larvae, and eggs? Take 3 minutes to watch Episode 2 of InsectXaminer, here: https://ag.umass.edu/landscape/education-events/insectxaminer .

That’s right – handpicking into soapy water works!

Impatiens downy mildew has shown up already in NYS greenhouses. It is appearing in double impatiens and also appearing in the standard bedding plant cultivars, even in relatively resistant varieties.

Consider keeping vegetatively-propagated impatiens cultivars separate from seed-grown types until you can be sure they are not infected. Remember how easily this disease spreads?

Check your impatiens for off color leaves and turn the leaves over to see the white fuzzy mycelium on the back (picture at end of message)

Also see https://s3.amazonaws.com/assets.cce.cornell.edu/attachments/2564/DM-homelandscape2-2.pdf?1409319821 for pictures of symptoms. Dispose of (carefully – the spores are airborne so don’t spread the disease on the plant’s way out) infected plants.

There are fungicides that can be used as protectants – even for the resistant cultivars if you have found impatiens downy mildew in your greenhouse. Remember – protectants work BEFORE the plants are infected.  Margery Daughtrey suggests Segovis and Stature and Segway as among the most reliable.  Other fungicides have had some resistance issues with impatiens downy mildew.

A more general statement on downy mildews:

The downy mildews are a group of oomycetes (AKA water molds) that are for the most part limited to a few host genera or to a family of plants.  So don’t expect downy mildew on rose to spread to your snapdragons. One of the most important of these diseases, Impatiens downy mildew, is limited to just the genus Impatiens, with hosts including the regular bedding plant as well as the double-flowered forms used in hanging baskets. Fortunately, though, the downy mildew of Impatiens walleriana does not bother the New Guinea Impatiens, Impatiens hawkeri.

Happy May Day!  The sun is out and I am feeling optimistic.  So here’s a more positive email!

Things to share with your customers! And tell them what you sell to help out.

I saw a great idea from Ball  – Search social media for people who are learning to garden and offer them help

especially Instagram, for #firsttimegardener, #firstgarden, #quarantinegarden and #victorygarden. Search for #ohiogarden, #michigangarden or wherever you are if you want to help someone closer to home.
