Utah program for growing food !
To look to food that just makes sense: organic, locally grown and healthy.
And interest in such foods is leading community supported agriculture farms -- known as CSAs -- to pick up business in Utah.
"The environmental impact of big factory farms and the cost in oil and fuel to move things from Baja, Mexico, to Salt Lake City ... it's sort of a mad system," said CSA farmer David Bell.
He and his family are offering an alternative to the "mad system," however, by harvesting vegetables by day that can be cooked up and on dinner tables within 15 miles of the growing site by night.
Bell Organic Gardens in Draper is one CSA expanding from Salt Lake City this year to serve new customers in Orem, Park City and Sandy.
As with all CSAs, customers of Bell Organic Gardens purchase a share of farm crops upfront at the beginning of the 18-week growing season. Customers then go to a designated location to pick up their weekly variety of vegetables -- ranging in variety from arugula and Asian greens to swiss chard and summer squash.
Most notable, then, is the increase in single, young people looking to participate in the CSA model, greatly varying from the stereotypical diet of Top Ramen and macaroni and cheese.

Pesticide Free Crop Protection- Organic
Biological control is a tool to be considered in constructing an integrated pest management scheme for protected crop production. In a complete integrated pest management program, diseases, weeds, and plant growth must be considered as well as insects and mites. But because we are entomologists, this discussion covers insect and mite pests of greenhouse crops only. With IPM, each crop must be considered individually. Some greenhouse crops such as tomato and poinsettia are especially suitable for biocontrol for several reasons. Tomatoes and poinsettias have relatively few insect and mite pests. They are not grown year round so there is a break in the production cycle. Biological control organisms can be used especially effectively for caterpillars, spider mites and whiteflies. Table 1 gives biological controls now commercially available. Table 2 is a list of pesticides that are compatbility with various natural enemies used for biological control in the greenhouse. Following the tables are recommended management practices that simplify the task of setting up a biocontrol program for a greenhouse crop and then there are some sources of natural enemies.
