Biostimulant Survey

Crop biostimulants are not biopesticides (suppressing pest and disease); instead, they are “substances or microorganisms that, when applied to seeds, plants, or the rhizosphere, stimulates natural processes to-- enhance or benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, or crop quality and yield”. Common active ingredients of biostimulants, which are distinct from those in biocontrol agents, comprise growth promoting bacteria and/or fungi, mycorrhizae, seaweed extract, humic substances, kelp, or plant hormones.  To better help vegetable growers with the use of crop biostimulant and implement our future research and extension programsplease spend a few minutes filling out the anonymous survey to share your experience, concerns, confusion, and hopes about an efficient use of these biologics. There are total of 8 questions. Once completed, please click “submit” to send your answers. Your response will be used for research and educational purposes only. Your participation is highly important and greatly appreciated. Questions about the survey? Please feel free to contact Dr. Zheng Wang (
