Application Pages

The objectives of the dropdata pages are:

• To provide public domain resource centre for information on the application of chemical and biological pesticides
• To develop linkages between institutions and individuals, interested in the optimisation rather than the promotion of pesticide use, through more efficient application techniques
• Provide a means of exchange, for data and ideas, consistent with the above

We seek further collaboration and hope these pages will "evolve" over the coming years. We currently provide information on the following:

• Spray nozzles and their performance
• Instrumentation for assessment of pesticide sprays
• Protocols for droplet sizing (BCPC)
• Types of pesticide application equipment
• Description of terms and concepts in spray application
• Acronyms, technical terms and organisations involved in pesticide science
• Tools for calibration of sprayers
• Application of biopesticides
• A (draft) format for the exchange of spray droplet data

Often relatively straightforward measures, such as fitting appropriate nozzles and calibration of existing spraying equipment, can make substantial improvements to the efficiency of application. Here, two CATIE scientists (Eduardo Hildalgo and Adolfo Martínez) are assessing the emitted flow rate (amount per minute) of a biopesticide to a rotary ‘Micronex’ nozzle fitted to a Stihl motorised mistblower.
