1997 Onion Disease Investigation Project in Orange County
(New York State Integrated Pest Management Program, 1997)The IPM Coordinator collected seed from many growers for testing in the spring. Field data was collected on 11 Blight-Alert fields on 10 farms throughout the 1997 growing season. -
1997 Report on the Use of Sudangrass for Improved Yield and Quality of Onions Produced on Muck Soils in New York
(New York State Integrated Pest Management Program, 1997)Prior to 1996, our field research focused on cultural aspects of Sudangrass, when to plant, planting rate, mowing vs. non mowed, mowing once vs. mowing multiple times, etc. In 1996, we obtained our first yield comparison ... -
A New Approach for Detecting Insecticide Resistance in Onion Maggot Populations
(New York State IPM Program, 2002)The goal of this research is to develop a rapid assay for identifying insecticide resistance in onion maggot populations. Development of an assay in which larvae can be tested for resistance to insecticides ultimately will ... -
A New Approach for Detecting Insecticide Resistance in Onion Maggot Populations
(New York State IPM Program, 2003)The primary goal of this research was to develop a rapid assay for identifying insecticide resistance in onion maggot populations and then to use it for predicting controllability of onion maggot infestations in the field. -
Altering Planting Configurations to Manage Bacterial Bulb Decay in Large-Scale Onion Production
(New York State IPM Program, 2012)Bacterial diseases of onions have become a serious threat to the sustainability of the New York onion industry. Losses up to 40% can occur as a result of reduced onion quantity and quality. Ultimately, an Integrated Pest ... -
An Evaluation of Fall Planted Broad Leaf Cover Crops on Muck Soils
(New York State IPM Program, 2001)Many onion fields have been in continuous, unbroken production for decades. Insect and disease populations build up when no rotation is employed. Over the last few years, onion bulb mites have increased as a problem. It ... -
Analysis of Onion Fields Following Rotation on Muck Soils in Orange County, New York
(New York State Integrated Pest Management Program, 1998)On May 31, 1998, the Orange county onion growing region was hit with a severe hail storm. Damage was extensive. Scouting was suspended during the month of June while growers figured out which fields they would keep and ... -
Analysis of Onion Management Practices as they relate to levels of Aspergillus niger (Black Mold) and Development of IPM scouting protocols for Black mold
(New York State Integrated Pest Management Program, 1999)The last four years, black mold (Aspergillus niger) has increasingly been a problem for Orange county onion growers. We intended to see if the procedure of rolling early season onions with green tops, prior to harvest, was ... -
Analysis of onion management practices as they relate to levels of Aspergillus niger (black mold) and development of IPM scouting protocols for black mold
(New York State IPM Program, 2000)The summer of 1999 was very dry. For most of the Orange county onion-growing region, rainfall was well below average or practically non-existent. The entire onion crop went down early. This situation did not allow for ... -
Annual Report for Smith-Lever Funded Projects
(New York State IPM Program, 2015)Weather based pest forecast models are important tools for IPM implementation. The Network for Environmental and Weather Applications (NEWA) (http://newa.cornell.edu) provides forecasts for important pests of fruits and ... -
Baiting Onion Maggot Flies with Bt
(New York State Integrated Pest Management Program, 1997)Laboratory studies conducted Dr. Eckenrode indicated mortalities close to 100% when adult flies were fed a 10% sugar solution laced with Bt insecticide. With present onion maggot control strategies focusing on the larval, ... -
Continued Evaluation of Fall Planted Broad Leaf Cover Crops on Muck Soils
(New York State IPM Program, 2003)Many onion fields have been in continuous, unbroken production for decades. Insect and disease populations build up when no rotation is employed. Over the last few years, onion bulb mites have increased as a problem. Some ... -

Detection of Systemic and Latent Presense of Botrytis allii in Onion Transplants
(New York State IPM Program, 2006)In New York, major outbreaks of Botrytis neck rot of onion, caused by Botrytis allii have occurred in association with the recent increases in growing onions from transplants. It has been suspected that bare-root transplants ... -
Developing a Biocompatible Management Strategy for Onion Maggot Flies
(New York State IPM Program, 2006)The current goal of our research is to develop a biocompatible management strategy for onion maggot flies that would replace the use of foliar applications of broad-spectrum pesticides. Foliar sprays are used in an attempt ... -
Developing a Biocompatible Management Strategy for Onion Maggot Flies
(New York State IPM Program, 2007)The current goal of our research is to develop a biocompatible management strategy for onion maggot flies that would replace the use of foliar applications of broad-spectrum pesticides. Foliar sprays are used in an attempt ... -
Development of IPM Elements for Key Crops in New York State
(New York State IPM Program, 2004)Integrated Pest Management (IPM) methods balance economic, environmental, and human health issues in pest management decision-making. This balance is achieved by careful consideration and implementation of all appropriate ... -
Effect of Barley Windbreak Placement on Onion Maggot Damage
(New York State Integrated Pest Management Program, 1997)In this report, we will examine the effect of the presence and absence of a barley nurse crop on the number of onion maggot flies in onion fields. We will also look at the effect of planting density of the nurse crop on ... -
Encouraging Adoption of IPM in Muck Onion Production Through the Use of Demonstration
(New York State Integrated Pest Management Program, 1997)Traditionally muck onion production in New York State has relied heavily on rigorous pesticide schedules to produce a quality crop. Methods such as crop rotation have not been used because onions are a high value crop grown ... -
Identification of crops which regulate soil population levels of Burkholderia cepacia causing bacterial canker and sour skin of onions.
(New York State IPM Program, 2002)Two approaches (field sampling and miniculture) were used to identify vegetable and field crops and other plant species which regulate population levels of Burkholderia cepacia in organic soils cropped to onions, and for ...
