Plants regulate their growth and development using hormones, including a group called strigolactones that prevent excessive budding and branching. For the first time, scientists led by UC Riverside have synthesized strigolactones from microbes. The work is published in the open-access journal, Science Advances. Strigolactones also help plant roots form symbiotic relationships with microorganisms that allow the plant to absorb nutrients from …

Grower-Shipper Association of Central California (GSA) — Implementing effective disease and pest management strategies is a continual challenge for farmers. While these challenges are not new in agriculture, they impact more than just farmers. Lower yields due to disease and pest pressure affects farm employees and harvesting crews too and can also inhibit our ability to provide a steady supply of affordable …

The dining time of different insects impacts a plant’s defenses and nutritional quality—a complexity uncovered in new research with implications for pest management strategies. A piercing-sucking, virus-carrying aphid has long worried pea plant farmers, but a more innocuous-seeming weevil that only takes tiny bites from leaves was found to also play a significant role in plant health. Depending if the …

The 2020 Agricultural Chemical Use Survey of vegetable producers collected data about pesticide use as well as pest management practices on acres planted to 22 different vegetable crops. NASS conducted the survey among producers in 18 states, focusing on the states that were major producers for the surveyed crops. (Fig. 1) Data are for the 2020 crop year, the one-year period …

The third edition of a booklet to help identify noxious and invasive weeds in New Mexico is now available. “Noxious and Troublesome Weeds of New Mexico” provides information on about 67 plant species that are ranked in five categories – noxious weeds categories A, B and C, watch list, and troublesome weeds not included on the noxious weeds list. New …

It has been heart breaking to seeing wheat and alfalfa fields dry up the last few weeks.  The recent hot temperatures caused many fields to wither, while placing greater irrigation needs on the few crops being irrigated with well water.   It’s the driest year I have experienced in my 10 years in the Klamath Basin! Several people asked me about …

Sutter County grows between 300 and 800 acres of fresh-market honeydew, mixed melon and cantaloupe each year. The fields vary between furrow and drip irrigation, with many fields in the Sutter Basin only receiving a pre-irrigation. Because of the rapid growth of melons, they are competitive with weeds and one cultivation may be sufficient to control weed issues. The growing …

Scientists from the Agricultural Research Service (ARS) are working to understand how something can be equally effective as both a government-approved food additive and as a pesticide. Methyl benzoate is a naturally occurring compound produced by plants. The U.S. Food and Drug Administration long ago approved methyl benzoate for human use; its fruity and floral aroma makes it a staple …

The U.S. Food and Drug Administration (FDA) has released a report on its investigation of the Salmonella Newport outbreak that caused more than 1,600 reported illnesses in the U.S. and Canada between June and October 2020. The FDA worked with the U.S. Centers for Disease Control and Prevention (CDC), state partners, and Canadian officials (Public Health Agency of Canada and Canadian Food Inspection Agency) to …

The Organic Center — Soil fumigants that fight soil-borne diseases and ensure crop production continue to be banned to protect the health and safety of rural communities. Organic farmers and conventional farmers who can no longer use these chemical tools need effective alternatives to protect their yields. A recent study published in the journal Agronomy(link is external) demonstrates that a non-chemical alternative can be …
