Should I use pest-exclusion nets? 7 tips from Sun Tzu’s Art of War

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

Thailand: Visiting Kasetsart University

In November, I  visited Kasetsart University and toured the Horticulture Innovation Lab Regional Center there and also the World Vegetable Center (AVRDC) demonstration garden nearby. It was great to see the new, central location of the Regional Center that showcases small-scale horticultural technologies.

Students at Kasetsart University were using the technologies in their class. Sliced bananas were drying in the chimney solar dryer (see above), next to a demonstration of solar-powered drip irrigation. Also on the site were Continue reading Thailand: Visiting Kasetsart University

Agricultural innovations at Kasetsart University, in SciDev.Net video

A video from SciDev.Net explores agriculture technologies at Kasetsart University in Thailand, aimed at the needs of smallholder farmers of horticultural crops.

The audio slideshow, “Simple agricultural innovation to empower farmers,” takes a closer look at several low-cost farming tools, including:

  • a cold room with a CoolBot for cooling fruits and vegetables after harvest
  • two solar dryers, including the UC Davis chimney dryer for drying produce
  • a solar-powered pump with drip irrigation system

Reporter Giovanni Ortolani interviewed Poonpipope Kasemsap, professor at Kasetart University, whose comments provide narration for most of the video.

“A lot of things can be done with a small investment, with innovations, in order to help the farmers so that they can live better lives,” Kasemsap says in the video. Continue reading Agricultural innovations at Kasetsart University, in SciDev.Net video

How drying beads work, in a new SciDev.Net video

Reporter Giovanni Ortolani visited with Horticulture Innovation Lab partners in Bangkok, Thailand, recently to learn about how farmers in humid climates can better save seed using drying beads. His video (below) and article “How seed-drying beads can empower farmers in the tropics” were published this week on SciDev.Net, a news website focused on science and technology for global development.

When stored in hot, humid conditions, vegetable seed deteriorates rapidly — lowering germination rates and farmers’ yields. Ortolani interviewed Patcharin Taridno, senior manager of seed technology with Rhino Research, about how the company’s zeolite-based “drying beads” can help farmers better dry seeds for storage by reducing relative humidity.
