Poinsettia Fungicide: Prevent Defense
Thursday, September 6th, 2007Our poinsettia crop will receive their second preventative fungicide drench tomorrow and this is the application that we tend to struggle to successfully apply. In previous seasons, our poinsettias tend to start showing signs of root rot after the second fungicide drench. I concluded last year that several factors cause this outbreak of pythium but […]
Biological Control: Update
Monday, September 3rd, 2007Well it’s been about 3 weeks since I released our predatory insects and we are starting to see some results. When I released the Orius the thrips populations were starting to increase quickly. Over the next 2 weeks, our populations increased a bit more in the first week and then remained stable in […]
Poinsettia IPM: Whitefly Control
Thursday, August 23rd, 2007So it’s time to start thinking about what I will use for whitefly control this year. Actually, I’ve been thinking about it for a while now and I think I’ll try to use a spray program this year instead of a systemic imidaclorprid drench. I’ve always drenched my poinsettias with Marathon or in […]
Biological Control: Update
Tuesday, August 14th, 2007I have received and released our Orius also known as the Minute Pirate Bug(I love that name). We have our sticky cards up so we will be able to track the thrips populations in this particular house and we will be able to track the level of control. Below are pictures I took […]
Biological Control of Greenhouse Pests
Wednesday, July 25th, 2007I have decided to put together a biological control program for some of our young plants this year. I was fortunate enough to gain experience using biological controls at a previous job and I feel very comfortable using them. I haven’t started a biological control program yet because the timing and conditions haven’t been right. […]
Poinsettia Propagation IPM/Disease Control
Friday, June 29th, 2007Whenever you propagate any unrooted cuttings, disease and insect control play a big role in a growers success or failure. For poinsettias, there are a few things that I always do to help ensure a successful poinsettia prop season. As far as insects are concerned, I am only worried agout fungus gnats. If you’ve ever […]
Greenhouse IPM. Thrips, Whiteflies and Aphids.
Tuesday, June 12th, 2007One of my mentors used to say “Kill ‘em Good” whenever he saw me in my Tyvek suit ready to spray for bugs. I’ve tried to pass this wisdom on to my growers, but I’m not sure if it’s sinking in. This season has been an especially difficult one with regards to pest […]
