Classical Biological Control of European Corn Borer

Hoffman, Michael P. (New York State Integrated Pest Management Program, 1997)

1. Introduce and release for establishment selected natural enemies of the European corn borer 2. Survey for establishment and impact of newly introduced natural enemies

TAg (Tactical Agriculture) 1997

Sutton, Philip L. (New York State Integrated Pest Management Program, 1997)

The 1997 growing season brought many challenges - a cold spring, a summer drought, and record potato leafhopper numbers. Farmers in 11 counties across New York State armed themselves to face these challenges and many more ...

Classical Biological Control of Soil Insects in Field Corn and Alfalfa

Shields, Elson; Testa, Tony (New York State Integrated Pest Management Program, 1997)

Recent research results in New York and Pennsylvania have shown that the entomb-pathogenic nematode Heterorhabditis bacteriophora ‘Oswego’ has a significant impact on the populations of corn rootworm, clover root curculio ...

Use of Trichoderma for Control of Soilborne Pathogens in Onions

van der Heide, Jan (New York State Integrated Pest Management Program, 1997)

Soil fungicides are only partially effective in controlling some soilborne fungal pathogens in commercial onion production, especially later in the season when fungicides applied at planting time have washed out or are no ...

Exploring methods for predicting and controlling European corn borer problems in processing snap beans

Stivers, Lee; Tucker, Frances (New York State Integrated Pest Management Program, 1997)

European corn borer contamination of processing snap beans has been a problem of increasing concern over the past several years. While this pest has a negligible effect on yield, extremely low tolerances for ECB contamination ...

Encouraging Adoption of IPM in Muck Onion Production Through the Use of Demonstration

Stivers, Lee (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 ...

1997 Onion Disease Investigation Project in Orange County

Ullrich, Maire; Rusinek, Teresa; Mishanec, John (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.

Effect of Barley Windbreak Placement on Onion Maggot Damage

van der Heide, Jan; Eckenrode, Charles J. (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 ...

Baiting Onion Maggot Flies with Bt

van der Heide, Jan; Eckenrode, Charles J. (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, ...

Reexamination of Grape Berry Moth Management Practices in the Lake Erie Region

Weigle, T.; Bixby, J.; English-Loeb G. (New York State Integrated Pest Management Program, 1997)

The Grape Berry Moth Risk Assessment (GBM RA) protocol was developed ten years ago by Hoffman and Dennehy (1987) to address the possibility of reducing the number of insecticide applications necessary to manage grape berry ...

Demonstrating a Postemergence Vineyard Weed Management Program

Weigle, T.; Dunst, R.; Bixby, J. (New York State Integrated Pest Management Program, 1997)

Under the row weed management in Lake Erie vineyards have traditionally relied on the use of a pre-emergence herbicide application in the spring followed by an application of a post-emergence herbicide in June (or around ...

Novel Use of Japanese Beetle Pheromone & Floral Lures to Reduce Grub Populations in Turfgrass

Villani, M.G.; Roelofs, L.W. (1997)

There has been considerable interest in the use of traps that incorporate 2 chemical lures, the first containing (R,Z,)-5-(1-decenyl) dihydro-2(3H)-furonone that mimics the female sex pheromone of this species (attracting ...

Minimizing Spray Programs for Control of Grape Diseases Based on Phenological Stages of Susceptibility

Wilcox, Wayne F. (New York State Integrated Pest Management Program, 1997)

1. Determine the optimum timing and minimum number of sprays to reliably control black rot. 2. Determine whether two fungicide sprays, applied immediately before bloom and 2 weeks later, can provide acceptable commercial ...

Validation of a Scarab Grub Sampling Plan for Home Lawns

Villani, Michael; Nyrop, Jan (1997)

A method of sampling lawns for deciding on the need for controlling European chafer larvae was previously developed.

Impacts of Conventional Turfgrass Pesticides on the Efficacy of Composted Amendments Used for the Biological Control of Turfgrass Diseases

Nelson, Eric B.; Craft, Cheryl M. (1997)

In the past few years, biological strategies of pest control have been attracting considerable attention among turfgrass scientists as well as golf course superintendents. The approaches are being viewed as an attractive ...

Management Strategies for Optimizing Summer Fungicides Applied to Apples in New York's Upper Hudson and Champlain Regions

Iungerman, Kevin (1997)

Elements of the Gadoury degree day model for forecasting primary apple scab season end, and the NY flyspeck model developed by Rosenberger, were employed to assess their usefulness in the control of sooty blotch and flyspeck.
