Characterization of Ground Nozzles for Pesticide Applications

چکیده
The introduction of the Drift Reduction Technology (DRT) guidelines by the United States Environmental Protection Agency has established testing protocols for nozzles, agrochemicals, application parameters, and combinations thereof, for applying agrochemicals in by certified individuals in the U.S. The Pesticide Application and Technology Laboratory in North Platte, Nebraska, USA sought to develop a large database of droplet spectrum data in regards to agrochemical applications by ground systems. The results of this study indicated that nozzle type had the greatest impact on the droplet spectra measured. DRT star ratings ranged from zero to four, depending upon nozzle selection and adjuvant inclusion. The results of this study indicated that factors that affect a droplet spectrum, which include nozzle type, tank-mixture components, and operating pressure should be tested together when submitting data to the EPA.

Comparison of field and model percentage drift using different types of hydraulic nozzles in pesticide applications
*Corresponding Author Email: [email protected] Tel./Fax: +90 322 338 6518 ABSTRACT: In pesticide applications, small droplets are desired for better coverage and uniform distribution. Yet, small droplets have a problem: Drift, the movement of droplets off-target. Low drift nozzle produces fewer drift-prone droplets, < 100 μm, compared to standard hydraulic nozzles. In pesticide applications, ...

متن کاملField data and prediction models of pesticide spray drift on coffee crop
The objective of this work was to generate drift curves from pesticide applications on coffee plants and to compare them with two European drift‐prediction models. The used methodology is based on the ISO 22866 standard. The experimental design was a randomized complete block with ten replicates in a 2x20 split‐plot arrangement. The evaluated factors were: two types of nozzles (hollow cone with...
متن کاملSummary of well water sampling in California to detect pesticide residues resulting from nonpoint-source applications.
This report summarizes well sampling protocols, data collection procedures, and analytical results for the presence of pesticides in ground water developed by the California Department of Pesticide Regulation (DPR). Specific well sampling protocols were developed to meet regulatory mandates of the Pesticide Contamination Prevention Act (PCPA) of 1986 and to provide further understanding of the ...
متن کاملMeasuring Spray Droplet Size from Agricultural Nozzles Using Laser Diffraction
When making an application of any crop protection material such as an herbicide or pesticide, the applicator uses a variety of skills and information to make an application so that the material reaches the target site (i.e., plant). Information critical in this process is the droplet size that a particular spray nozzle, spray pressure, and spray solution combination generates, as droplet size g...
