I am looking for a systemic chemical for spider mites on tropical hibiscus. A local garden center recommended Hi-Yield 38. Do you have a recommendation. I have 200+ plants.
Neither Talstar P Professional Insecticide or Hi-Yield 38 are systemic products. We are unaware of any systemic product that is labeled for use for spider-mite control as a soil drench. This pest is mainly treated with foliar sprays with something like Talstar P, Avid (which is a translaminar systemic – meaning absorbed through the leaves), or Hexygon DF.
