Crop biostimulant is abundant and complex in its function, causing plethora of questions on selecting, using, and evaluating its on-farm efficacy. The first and maybe the foremost step toward a more effective use of crop biostimulants among vegetable growers is to understand their current use, experience, concerns and hopes. To accomplish the task, a survey was sent out to collect the specific information from vegetable growers mainly in the San Joaquin Valley and other counties in California. I recently published the results of the survey at Progressive Crop Consultant. You can read the article following the link: https://progressivecrop.com/magazine-archive/march-april-2021/. Excerpts of figures from the article are shared here. The results was also reported in the recent Biostimulant World Congress at https://informaconnect.com/biostimulants-world-congress/speakers/zheng-wang/#science-track-session-5-the-future-of-biostimulants_voice-from-california-vegetable-growers-on-crop-biostimulants-impression-concern-and-hopes
