Are all your greenhouses tucked up for winter? And all those poinsettias sold? Just think, you could be Christmas tree producers!
Do we need another disease on chrysanthemums- especially one carried by thrips? Are growers seeing this in NYS? MSU’s research report on tomato spotted wilt on chrysanthemum.
Oh goody, another chrysanthemum disease that looks similar to TSWV! This stem necrosis virus on chrysanthemum has only been seen in Korea so far. Whew!
On the plant growth regulator front . . Information from Joyce Latimer at Virginia Tech on why PGR labels aren’t specific by crop. And e-GRO’s PGR MixMaster app to help you calculate amounts. There are lots of other reports on PGR application research at e-GRO, too.
And in preparation for next year’s poinsettias – can you really start too soon thinking about them? – an article on biocontrol for poinsettia
And information on aerial blight on poinsettias – an uncommon disease caused by our unfortunately common friend Phytophthora (so common I was forced to learn to spell it correctly) (remember to check NYSPAD for NYS labels of any pesticides)
Oh, just one more beast to keep an eye out for – and aphids are likely to pop up earlier in the spring than we like – the foxglove aphid. Getting to be much more common in greenhouses.
Well maybe another – broad mite in pepper. Do you have gnarly looking leaves? Look VERY closely for this pest.
Enough for this time!
Some lovely sunny days lately! Have a great week!
