How Many Dollars Are Falling Off Your Greenhouse Bench?

Author: Paul Thomas

Losing plants to disease and insects, nutrition or neglect happens to all of us. Our goal for publishing the e-Gro series of alerts and seminars is to give you advanced awareness of issues and potential way to address them.  Still, losses happen, and in my recent greenhouse visits, I started noticing the trash cans were staring to hold plants that had to be trashed.  From January through early March, losses are traditionally very low, and unless there was a plug shipping problem, crops seem to do pretty well.  Right about now, we start seeing the first losses due to diseases and insect issues.  As the season goes on, we add losses due to missed irrigations, mishandling, and nutritional issues.  By the end of the growing seasons, we see loses due to leggy stretched or beyond market stage plants being dumped.  When I chat with growers, the usual statement is:  “well, it’s only 2% of the crop, or we kept losses to under 10% this year…” My response?  “Oh my….”

Three Factors That Can Impact The pH Of Growth Media

Author: Brian Sparks

The pH of water used in plant production is important when it comes to mixing with pesticides and dissolving micronutrients in water. However, according to Jose Chen Lopez, a horticulture specialist with Premier Tech Horticulture, the water pH has little influence on the pH of the growing medium. Other factors impact the pH of the growing medium.

Let’s not forget 2007…


The forecast is eerily reminiscent of 2007. Let’s not forget that the last frost date for north GA is a month out! Please consider the prospect of a late freeze when considering if you should remove cold frame covering. I wouldn’t do it until April 10…


 

USDA adds seven (7) Georgia counties to the Emerald Ash Borer Quarantine Area

On February 22, 2016 The USDA Animal and Plant Health Inspection Service (APHIS) added Barrow, Cherokee, Douglas, Fannin, Habersham, Murray, and White Counties in Georgia to the list of regulated areas for the Emerald Ash Borer (EAB). The Federal Quarantine specifically regulates the interstate movement of EAB-host wood and wood products from the quarantined areas in Georgia including firewood of all hardwood species, nursery stock, green lumber, waste, compost, and chips of ash species.

 

There are now 19 Georgia counties under the EAB Regulatory Quarantine. See The Georgia Forestry Commissionhttp://www.gfc.state.ga.us/forest-management/forest-health/eab/index.cfm or Georgia Department of Agriculture website http://www.agr.georgia.gov/emerald-ash-borer-eab.aspx for a map and list of the regulated Georgia counties and for information about EAB identification, damage symptoms, photographs, life cycle and quarantine regulations.

 

The Emerald Ash Borer (EAB) is a non-native and highly invasive insect that has killed tens of millions of ash trees in 25 states and in Canada since it was first discovered near Detroit, Michigan in 2002.  It is thought that EAB was accidently introduced into the U.S. from Southeast Asia in infested shipping containers and materials. EAB kills both vigorously growing and weakened ash trees.
