Pest-exclusion nets are one of the technologies for horticulture development promoted by the Horticulture Innovation Lab. The nets can be easy to use and can also serve as floating row covers to control temperature, light, relative humidity and soil moisture for plant production. Some of the pest-exclusion nets used by Horticulture Innovation Lab researchers are made and marketed locally by mosquito net manufacturers.

But why should you consider using nets for pest management? Here are 7 considerations in adopting nets for agricultural use, inspired by Sun Tzu’s The Art of War:

  1. The greatest victory is that which requires no battle:
    The nets create a barrier that protects vegetables against pests and associated diseases, and thus provide an inexpensive and safe method of managing insect pests while reducing risks associated with pesticides to both farmers and consumers. The pest-exclusion nets provide an excellent example of victory (against certain insects) which requires no battle (insecticide).  Continue reading Should I use pest-exclusion nets? 7 tips from Sun Tzu’s Art of War

5 ways relationships promote innovation – and can improve food safety

Editor’s note: This blog post by Karen LeGrand was originally a presentation given at the Horticulture Innovation Lab’s 2017 annual meeting.

LeGrand is a UC Davis researcher who helps manage a Horticulture Innovation Lab project focused on building safe vegetable value chains in Cambodia along with an international team from the Royal University of Agriculture, the University of Battambang and iDE Cambodia. Their team builds on lessons learned from a previous project in Cambodia.

What do relationships have to do with innovation and food safety? Our project is built on the idea that when we focus our work around the shared interests of a community, it can bring people together in participatory ways that result in innovation and sustainable change.

One example from the first phase of our project was a situation where a marketer wanted to purchase vegetables that were considered “safe” (free of microbiological and chemical hazards). Farmers participated with our research team to conduct trials aimed at identifying appropriate ways to change farming and postharvest practices Continue reading 5 ways relationships promote innovation – and can improve food safety

Building trust in food systems – here and in Cambodia

A version of this article originally appeared in the UC ANR Food Blog.

What is the role of trust in our food system? In the United States, our trust in food is often implicit. We can generally trust that the fruits and vegetables we buy at a grocery store or farmers market are safe to eat — and we are often free to shop without even thinking about that trust.

Between farmers and agricultural scientists too, trust often plays an important role. If you’re a farmer, you need to be able to trust that investing your time or money in a new technique or in attending a workshop will indeed improve your business.

But it can be easy to forget that trust is a critical first step in many of these agricultural relationships.
