Diversified Farming Better for Wildlife

A study by scientists at Stanford and the University of California, Berkeley, published in Science, shows that evolutionarily distinct species suffer most heavily in intensively farmed areas. They also found, however, that an extraordinary amount of evolutionary history is sustained in diversified farming systems, which outlines a strategy for balancing agricultural activity and conservation efforts.

Cover Crops for Pest Management

Two small farmers in Florida are partnering with University of Florida Extension to determine how cover crops can be used to manage insect pests. In a newly funded Southern Sustainable Agriculture Research & Education On-Farm Research Grant, “Establishing and Evaluating Selected Cover Crops on Small Farms to Increase the Impact of Beneficial Arthropods on Crop […]

Bugs as Bio-Control

University of Adelaide Ph.D. student Rebecca Kittel has discovered 18 new species of tiny parasitic chelonine wasps which have potential to be used as biological control (bio-control) agents as they specifically target individual varieties of moths. The adult wasps inject their eggs into the eggs of host moths. The wasp larvae feed and develop inside […]

Neonicotinoid Risks Outweigh Benefits

Center for Food Safety released a scientific literature review which reveals that neonicotinoid insecticide seed treatments offer little benefit, do not increase crop yields and cause widespread environmental and economic damage. In particular, neonicotinods have been implicated in bee population declines and colony collapse. The authors examined 19 peer-reviewed studies of the relationship between neonicotinoid […]

Potatoes being harvested in the San Luis Valley of south-central Colorado. Rotating potatoes with cover crops provides many benefits, including nitrogen management, improved soil and water quality, and bigger potatoes and higher yields.

Three-Year Rotations Best For Potatoes

Agricultural Research Service (ARS) scientists have been investigating new cost-efficient options for increasing yields of potatoes and improving production sustainability. The researchers determined that three-year crop rotations generally helped break the host-pathogen cycle more effectively than two-year rotations. The three-year rotations provided better disease control and resulted in higher crop yields. These rotations also supported […]

Citrus Growers Use Biocontrols

Citrus growers in California are now turning to a natural solution after pesticides have been shown to be ineffective. Teams of invasive species experts have started releasing tamarixia radiate, a tiny parasitic wasp, to control the invasive Asian citrus psyllid population. Asian citrus psyllid can spread a disease which causes greening, devastating citrus production. This […]
