Dear California weeders, I organized a symposium on the business of weed control at last week's WSSA meeting which contrasted the state of the agrochemical industry with engineering companies that are developing automated weed removal technology.
I visited an onion field where I saw this interesting emergence pattern with annual bluegrass (Poa annua L.). Onion beds are listed in east-west orientation (as seen in pictures). We can see annual bluegrass emergence only on the south facing slopes and none on bed-tops or north facing slopes.
UC Rice Advisor Whitney Brim De-Forest is using a spray chamber to apply a foliar organic fertiliser to rice. She uses the chamber to make sure that they are applying a precise amount of the product. Thanks to @balde.hamady for the video! https://www.facebook.
Over the past year and a half, I have been conducting research and extension with weedy (red) rice (Oryza sativa L.), which has re-emerged as a pest in California rice fields. What makes this plant so interesting is that it is the exact same species as cultivated rice (also Oryza sativa L.).
