Comparing biological fungicides in greenhouse tomatoes

This project will assess yield and disease levels on organic greenhosue tomatoes, to provide Best Management Practices for foliar disease control using biological fungicides. J Reid, jer11@cornell.edu, 315-536-5123

Nitrogen fertility and foliar disease management with compost tea and rescue treatments in organically-grown tomato

Naturally occuring bacterial speck, powdery mildew, and Septoria leaf spot on tomato were treated with compost tea, Sonata, JMS stylet oil, and Champion WP copper. There were no significant differences found between treatments. M McGrath mtm3@cornell.edu 631-727-3595

Biopesticides for Powdery Mildew on Pumpkin

This study looked at 6 plant oil products, sulfur, and OxiDate in their ability to control powdery mildew. All products offered some control, with GC-3, Organocide, and Eco-E-Rase as effective as Microthiol Disperss, JMS stylet oil, and Bravo conventional fungicide, at 76-92% control. Other products tested were Bugitol, Sporan, and Trilogy. M McGrath mtm3@cornell.edu 631-727-3595

Compost Tea and Rescue Treatments for powdery mildew control on pumpkin

Compost tea was tried alone and in combination with Serenade, Sonata, JMS stylet oil, and Champion WP for control of powdery mildew. PM resistant variety choice offered the best disease control. M McGrath mtm3@cornell.edu 631-727-3595

Aerated compost tea and other alternative methods of disease control in pumpkins

Ground basalt, bordeaux mixture, aerated compost tea, and silica spray in various combinations were applied to pumpkins. None of the treatments had any significant difference in disease suppression of bacterial wilt, downy and powdery mildew. M McGrath mtm3@cornell.edu 631-727-3595

Biological Inoculant for disease control in high tunnel bell peppers

This project will evaluate Bio-Yield (Bacillus sp.) for disease control and yield increase in colored bell peppers in hight tunnels. J Reid jer11@cornell.edu 315-536-5123

Improving Disease Management and Production in Tomatoes

This project assesses the performance of Chickling Vetch as mulch and N source, and efficacy of Organocide and/or Copper fungicide to control foliar disease. M McGrath mtm3@cornell.edu 631-727-3595
