Extension Vegetable Program Completed Projects
In New England, European corn borer and pepper maggot are the most common insect pests of pepper fruit. In many locations, peppers picked at the green stage are only marginally affected by ECB, but those left in the field long enough to ripen fall prey to ECB, then to soft rots. During the 2012 season, the UMass IPM team worked with several growers to see if releases of the parasitic wasp Trichogramma ostrinae could increase their yield of healthy bright red and yellow fruit. In the process, the team observed increased incidence of pepper anthracnose in the fields in which they were working.
We worked with Massachusetts growers on a broad range of activities related to Integrated Pest Management for diversified vegetable and fruit farms. One of the core components of this project is working with several 'mentor farms,' who grow both fruits and vegetables and are open to expanding their use of advanced integrated pest management techniques as well as working with us to better understand how a diversified farm can use IPM. We also conducted field trials on-farm and at our research farm on IPM methods identified by growers as their priorities each year. We shared what we learn on each of these farms by holding twilight meetings, posting pest alerts, and writing IPM articles for publication on our websites, newsletters, and facebook page.
Beginning in 2010, project participants at the Universities of Massachusetts and New Hampshire Extensions, along with two local food organizations, Community Involved in Sustaining Agriculture (CISA) in western MA and Seacoast Eat Local (SEL) in eastern NH conducted research trials, and collaborated with winter vegetable producers throughout New England on methods for production, storage, and marketing to strengthen this aspect of the regional food system.
Reduced and modified tillage (RT) systems (e.g. no-, zone-, strip) represent strategies to reduce soil degradation and erosion and protect water quality. Previous research has shown that these tillage systems can provide the environmental and economic benefits of a RT system for many vegetable crops without the harvest delays or losses observed in straight no-till.
This project focused on shelled corn, a renewable heat source that can be grown and used in Massachusetts more cheaply than fossil fuels, using available and proven technology. Changing to energy sources that can be produced locally, travel a short distance from producer to user, and that have a high ratio of energy output to fossil fuel input is key to a viable future for farming in Massachusetts.
