Allium leaf miner update: 03/24/20

Allium Leaf Miner

Allium leaf miner (ALM) feeding/egglaying scars were detected in chives near Princeton (Mercer Co.), NJ on Tuesday of this week.  This indicates that the first (spring) flight of these flies has now begun and damage will increase.  Additionally, extension personnel at Penn State have reported finding the first feeding scars in several southeastern PA sites within the past few days.  It is believed that all of these occurrences are very recent.

Growers should consider initiating the control method of their choice at this time.  Affected crops include chives, scallions, garlic, onions and leeks.

Floating row covers, kept on until this flight ends will help minimize access to plants.  Insecticide applications targeting adults may be helpful as well, although frequency of applications is uncertain.  Spinosyn materials (Radiant, Entrust (OMRI approved)), pyrethroids (Mustang Maxx, Warrior),  neonicotinoids (Scorpion, Venom) and the insect growth regulator Trigard are labeled for miner control.

Adult activity and observations of feeding will be reported on in the IPM Update as they occur.  At this time, all growers should respond to the first adult generation.  We will attempt to identify the end of the first flight so that growers know when the risk of infestation has abated.

ReadyAG – Dealing With Disaster May Be The Last Thing On Your Mind, But Are You Prepared?

The COVID-19 posts asking if your business could survive if you, as owner/operator/key manager, got sick reminded me that we never ‘plan to fail, but to often fail to plan’! ReadyAG is an online self-assessment tool that is meant to help you do just that. You can download the entire workbook or use the online versions to conduct your own review of your ability to deal with a disaster, make prioritized lists of items you might need to address, and create contingency plans and contacts to put all essential information into a centralized plan.

Hopefully COVID-19 avoids our farm community, but the ReadyAG workbook can be an eye opener about your farm business’s ability to cope with any disaster.
