This applies to all sweet corn producers. Researchers at the University of Rhode Island are currently distributing an online survey about fresh market sweet corn. If you grow fresh market sweet corn you are eligible to take this short 5-minute online survey.
Your participation and feedback are extremely valuable to the success of this research. The survey will gather information on growers’ bird damage levels to sweet corn and prevention methods used to deter bird damage.

We thank you in advance for taking this survey. If you have further questions or interested in this study please see the contact information below.

Allium leaf miner update: 04/09/20
Allium Leaf Miner
Allium leaf miner (ALM) adults were captured in higher numbers (16/week) on yellow cards in Princeton (Mercer Co.), NJ on Tuesday of this week, while lower numbers (2) were found near Milford, Hunterdon County. Additionally, a garlic field near Asbury on the Warren/Hunterdon border was found to have 64% of plants exhibiting feeding/egglaying scars. This indicates that the first (spring) flight of these flies is now in full swing, and damage is ongoing. ALM flies were observed on foliage in all fields that were inspected this week.
Growers should consider implementing 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. The diamide, Exirel, is permitted in NJ under a 2ee label as well.
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.

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.

Allium leaf miner update: 09/20/19
Allium Leaf Miner
Allium leaf miner (ALM) feeding/egglaying scars were detected in chives and scallions near Princeton (Mercer Co.), NJ on Friday of this week. This indicates that the second (fall) flight of these flies is now underway, and damage is occurring.
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 the second 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), and pyrethrin materials (Pyganic (OMRI approved)), 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 second adult generation. We will attempt to identify the end of the second flight so that growers know when the risk of infestation has abated.

Veg IPM Update: Allium leaf miner 04/10/19
Allium Leaf Miner
Allium leaf miner (ALM) feeding was detected in one commercial planting of chives near Lawrenceville, NJ on Tuesday of this week. Degree-day accumulations at this site were 46.5, base 50 F as of Tuesday. Sticky traps at this same site yielded no flies. Additionally, trap and inspection sites at Milford (Hunterdon Co. (garlic)), and Oldwick (Hunterdon Co. (garlic and chives)), had neither feeding signs nor flies on sticky cards.
Within the week, another monitoring site near Hackettstown (Warren Co.) will be added. Reasonable spring weather that we are now experiencing is conducive to the development of the first adult generation. Growers should consider initiating the control method of their choice at this time. Affected crops include chives, scallions, garlic, onions and leeks.
