Todd Statzer, the Vice President of Environmental Sciences at urban-gro, offers some tips for pesticide use in cannabis cultivation.
Back to the Root—The Role of Botany and Plant Physiology in Cannabis Testing, Part II: Plant-Pesticide Interactions and Plant Defense
Here we discuss the ways in which chemical pesticides interact with plant physiology.
This application note outlines a QuEChERS extraction approach coupled with either traditional dSPE clean-up versus UCT’s dSPE clean-up in a 96 wellplate format.
Up in Smoke: The Naked Truth for LC–MS/MS and GC–MS/MS Technologies for the Analysis of Certain Pesticides in Cannabis Flower
A study using LC-qTOF, GCqTOF, and GC–MS/MS to evaluate the selectivity of a model pesticide commonly found in regulatory target lists.
Right From the Grow: A Look at Sampling and Sample Preparation Methods of Solid Cannabis for Analysis
Laboratories are challenged with highly regulated and difficult sample schematics, sample preparation, extraction, and testing procedures that try to ensure accuracy and precision of testing. Accuracy in analytical testing starts at the very beginning with sampling and sample preparation prior to testing.
Too often, cannabis laboratories get different results on the same sample. There are a number of causes and solutions. In this installment, the problem is presented along with its causes.
Cannabis distillate samples spiked with known amounts of pesticides were submitted to five cannabis testing laboratories—here are the results.
LC–MS/MS with ESI and APCI Sources for Meeting California Cannabis Pesticide and Mycotoxin Residue Regulatory Requirements
How two different LC–MS/MS methods with ESI and APCI were used for low-level analysis of 72 pesticides
As more states legalize cannabis, increasingly stringent testing requirements are being developed on the state level for pesticide and mycotoxin levels in cannabis products.
For U.S. states that have legalized the recreational or medicinal use of cannabis and cannabis products, there are presale testing requirements meant to address quality and consumer safety (1–3).
