Farming Tips for Enduring Historic Drought in Northern CA

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 …

Conventional Melon Weed Management in the Sacramento Valley

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 …

An Organic Alternative to Combatting Spotted Wing Drosophila

A recent study published in the journal Agronomy(link is external) demonstrates that a non-chemical alternative can be …

Fusarium Wilt of Watermelon 2021

Last year we had a lot of watermelon fields infected with Fusarium from Winterhaven to Yuma, Wellton, and Mohawk Valley. Rain, and overwatering of fields when plants set fruits might have contributed to the disease development.

Summer Sanitation is Important as Ever

It is never too early to start planning for next produce season, particularly with the threat of Impatiens Necrotic Sprot Virus (INSV) looming.

Overall, INSV incidence was very low (~1% incidence), but there were a few fields where incidence was estimates at > …

Whitefly Management on Spring Melons 2021

Now that the produce season is essentially finished in Yuma, it is time to move into melons.  Spring melon crops are rapidly growing, and so are insect pest populations. Cabbage loopers and leafminers are becoming evident in some areas, and PCAs should start ramping up their monitoring and sampling. More importantly, whitely populations are quietly becoming abundant on the spring …
