Can We Improve Pesticide Application in Greenhouse Ornamentals?

As anyone battelling whitefly on poinsettia this season can attest to, good pesticide coverage in ornamental crops can be challenging. Hydraulic sprayers are the industry standard, but does that mean they’re the best option? Where does sprayer technology need to go in the future to get growers better results?

This summer, Dr. Jason Deveau, OMAFRA’s official “Spray Guy”, and myself did a trial at a local greenhouse with some experimental equipment to try and answer these questions. The results were intriguing, to say the least.

For all the details on this trial, check out the link to Jason’s blog post, below.

OMAFRA CEA Webinar Series: Smart Sensors for Floriculture

Ever thought your plants were looking a little chlorotic, but didn’t want to waste time or money on tests? What if an smartphone app could tell you their nitrogen level? What if low cost sensors could help you monitor plant growth and tell you when PGRs are needed?

Having previously covered topics such as artificial intelligence and smart spraying, OMAFRA is continuing it’s CEA Webinar series, looking specifically at smart sensors. And they don’t have to be anything fancy to help you monitor your crop.

Although “floriculture” is in the title, the sensors and apps Dr. Krishna Nemali from Purdue University will discuss have applications across all avenues of controlled environment agriculture. Keep reading for details on the webinar, and how to register.

Knowing when to apply PGRs to crops like poinsettia is critical. A smart phone app could help make things easier with less staff training.

Water Treatment: What System Should I Choose?

Water media filter in a greenhouse
Media filters can be an important step in water treatment: see this article in Greenhouse Grower.

This is the 6th article in a series about water sanitation. The goal of this series is to get you reflecting on your own irrigation system before a problem occurs. 

If you’re following our series on water sanitation, you saw that previous posts covered where problems are likely to occur in your greenhouse, the types of pathogens found in waterwhere and how to sample your water and getting and interpreting a DNA test for pathogens in your water.

This post covers water treatment options, and was written by C. Dayboll with input from Phytoserv and Soil Resource Group.

Water DNA Tests: Pros, Cons and Interpreting Results

This post was written by S. Jandricic and A. Wylie.

Overhead boom irrigation

This is the fourth article in a series about water sanitation. The goal of this series is to get you reflecting on your own irrigation system before you are faced with a problem.  The first post covered where problems are likely to occur in your greenhouse ; the 2nd covered the types of pathogens found in water and the 3rd covered where and how to sample your water.

Once you’ve got your water sample, this post will cover why water DNA tests are useful, and how to interpret the results. This is the next step towards identifying and then treating your water issues to prevent unnecessary fungal or bacterial disease in your greenhouse crops, and potentially save you thousands of dollars in crop losses or fungicide applications.

These posts make good refresher resources, so make sure to bookmark them!

The Whitefly “Tipping Point”and Testing Pesticides in Poinsettia

It’s that time of year again where you have to make a choice with your poinsettia. Do you stay the course with natural enemies, or abandon your bio program and spray  for whitefly? And spray with WHAT?

This post has tips on how to test pesticides NOW, so that when it comes down to the wire, you’ll know what is – and isn’t – working.

Comparing Biocontrol to Pesticides for Bemisia Whitefly Control in Poinsettia

P1020349

T’is poinsettia sticking season once again, and the question always comes down to the same thing: do I use chemicals to control Bemisia whitefly and hope it works this year? Or do I switch to biological control?  Here we show some head to head comparisons that can help you decide.

An in-depth discussion of this topic was also captured by MSU’s “Bug Bites” last year, and I’ve included the video below.

Now that poinsettias are safely tucked into their prop trays and the threat of Erwinia (Pectobacterium) is almost over, it’s time to think about other poinsettia issues.

Root rots, nutritional issues, environmental stress and PGR mistakes can all be costly in this high-value crop.

Read on for common pitfalls and how to avoid them, and for some great video resources on poinsettia production.
