Reference tools

In addition to the Handbook, PMTP has developed or assemble some tools or guides that you may find useful. Here's a brief description of our tools:

Efficient Use of Speed Sprayer Technology

We developed an interactive application that allows you to enter in sprayer and orchard information to help you see the effect of driving speed on sprayer efficiency to help you determine the most efficient and effective way to use your equipment. Click on Speed Sprayer Use to use this tool.

Guide to Identifying Adult Codling Moth in Early Season Traps

We put together a visual guide to help you determine if the moth in your early season traps is really an adult codling moth or the sage moth. Click on Adult CM ID to view this guide.

Maximum Residue Levels Database

An additional complication for selecting the right pesticide for your orchard situation is knowing if you will be able to market your fruit in other countries. We briefly explain the concept of Maximum residue levels and provide links to online databases where you search on various pesticides, crops and countries to see if the chemical you wish to use is even allowed in the country you wish to market your fruit.
Part of our current project is to develop an MRL database with NHC that will be integrated into DAS. This will allow you to automatically look up the known MLS information for the pesticides listed in the crop protection guide where DAS derives its pesticide information. Click on Max.

IPM Resources links

Located in the right hand column is a list of hand picked IPM related web page resources that we feel should be useful. A couple of the pages are a bit dated, but the information is still accurate and applicable. We especially recommend the use of the Decision Aid System (DAS) to help you with your orchard pest and disease management decisions. If you haven't tried it recently, check it out. There are many new features and more to come.
