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!
