Scouting to Reduce Chemical Pesticide Use in Greenhouse Ornamentals
Attention Growers! Did you know that scouting your crop can help you find problem areas and allow you to make more timely interventions for management before things get totally out of control? Have you ever wanted to come up with a scouting routine or modify your existing one? The following steps and handouts will guide you step by step on how to come up with the most efficient way that works for you!
Step 1: Establishing a Scouting Program - Step by Step - This handout will guide you through how to use the following steps and supporting documents.
Step 2: Come up with early and late season Action Thresholds (Handout 1)
Step 3: Choose a scouting form that best suits your needs. Handouts 2a and 2b are intentionally blank so you can draft your own plan if you choose not to adopt one of the example forms below.
Handout 2a: Draft your own template
Handout 2b: Draft your own template
Example 1: Sticky cards only (actual numbers)
Example 2: Plants only (presence vs. absence)
Example 3: Cards & plants format 1 (actual numbers or comments)
Example 4: Cards & plants format 2 (actual numbers or comments)
Example 5: Cards & plants format 3 (infestation range)
Step 4: Map a scouting plan/route for your greenhouse. Map Template
Step 5: Scout your greenhouse!
Step 6: Keep track of your results using a graph. This Graphing Template example will allow you to keep track of
your sticky card counts.
webpage was developed to provide educational materials and survey
results from an intensive 2 day pilot IPM training session held
for growers in ME, NH and VT in March 2012.
pilot project empowered growers of greenhouse ornamentals in Northern New
England to establish formal scouting programs by training seasonal workers on
pest and disease diagnosis and soil and water testing. This thereby reduced
growers’ use of agrochemicals and increased their adoption of integrated pest
management (IPM) and biological control. The goal of the training session was
to provide participants with sufficient knowledge, confidence and expertise to
establish an effective scouting program. Data was generated from surveys
completed before the training, immediately after the training and at the end of
the season to quantify the impact of scouting in general and the usefulness of
this pilot project.
