Available in PDF, EPUB and Kindle. Book excerpt: "What nozzle should I use?" That's a complex question. And the answer to the question is becoming more complicated, especially with greater emphasis on tank-mixtures to deliver multiple effective pesticides against target pests. Some of the many nozzles on the market can reduce particle drift. Would these nozzles be right for you? Whether a low-drift nozzle fits your program depends upon your spraying needs and operation. Drift-reducing nozzles typically produce larger droplets and penetrate the plant canopy when target plants are larger, but larger droplets may shatter and be lost to the soil surface when using contact pesticides and target plants are small. Nozzles that produce smaller droplets provide better coverage and the pesticide is retained better on the leaf surface, especially when the target plant is smaller. However, small droplets are more susceptible to particle drift. Which scenario is right for you? Probably a combination of both.

This book was released on 2016-10-14 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first update to this key reference guide in over 15 years! This revised edition contains a new format making it even easier to study for the DPR exams. In addition to the review questions found at the end of each chapter, this new edition contains knowledge expectations at the beginning of each chapter. These brief statements describe what you are expected to learn after reading that chapter, allowing you to study more effectively for DPR’s pesticide applicator licensing (QAL/QAC) exams. These knowledge expectations are also highlighted in sidebars throughout each chapter, providing a study roadmap so you know which sections of each chapter are most important. Also new: Updated pesticides table to reflect products available in CaliforniaUpdated information on nematodes, vertebrates, and pathogensExpanded information on environmental hazards, expanded information on personal protective equipment including EPA respirator criteriaUp-to-date information on worker protection standardsExpanded information on pesticide resistanceUpdated compliance guidelines for pesticide use reporting as required by California lawA dedicated chapter covering label reading, including an updated label that reflects current regulations The Safe and Effective Use of Pesticides provides detailed information for selecting, using, handling, storing, and disposing of pesticides. It emphasizes worker protection, prevention of groundwater contamination, protection of endangered species and wildlife, and reduction of environmental problems. This is a significant update to the 2nd Edition, so everyone will want to update their reference library with this new edition. The principles described in this volume apply to all areas of pest control, including agricultural, structural, landscape, greenhouse, and public health applications. Volume 1 in the Pesticide Application Compendium. This is recommended study material for all categories of the California Department of Pesticide Regulation’s (DPR) Qualified Pesticide Applicator License (QAL) and Qualified Pesticide Applicator Certificate (QAC) exams.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the nozzle types Agrotop TDXL 80-015, TDXL 80-02 and TDXL-D 110-02 were investigated to classify their drift reduction potential for downward spray applications (at 2, 3 and 3 bar spraying pressure, respectively). The uniformity of the spray distribution was tested on a patternator for the appropriate nozzle height (default height 0.50 m; for the 80-degree nozzles lowered to 0.30 m). For all three nozzle types the resulting coefficient of variation (CV) was less than 10%. Droplet size measurements were done using a PDPA system and the resulting droplet size spectra and droplet velocities were used in the IDEFICS spray drift model. Spray drift deposits on a standardized ditch were computed, as well as the corresponding drift reductions compared to the reference situation. According to the current classification system for drift reducing nozzles, the drift reduction capability of all nozzle types must be evaluated at nozzle height 0.50 m above the crop. At this nozzle height and a nozzle spacing of 0.50 m, nozzle type TDXL-D 110-02 could be classified as 75% drift-reducing (DRD75) at liquid pressure of 3 bar. At a nozzle spacing of 0.25 m, the nozzle types TDXL 80-015 and TDXL 80-02 could also be classified as DRD75, at a nozzle pressure of 2 and 3 bar, respectively. Therefore, these 80-degree nozzle types are eligible to be used as DRD75 nozzles at the given liquid pressures in the drift-reducing technique (DRT) of ‘lowered sprayer boom’.

Available in PDF, EPUB and Kindle. Book excerpt: The development and testing of drift reduction technologies (DRTs) have come to the forefront of application research in the past few years in the United States. DRTs can be spray nozzles, sprayer modifications, spray delivery assistance, spray property modifiers (adjuvants), and/or landscape modifications. A protocol for testing DRTs in high speed wind tunnels has been previously reported and was expanded to test spray nozzles. This manuscript reports on the initial implementation of the DRT program for conducting DRT evaluations of three spray nozzles under high speed conditions i.e., 45-65 m/s (100-140 mph), which are relevant to the aerial application of crop production and protection materials. The spray nozzles were evaluated in the USDA-Agriculture Research Service High Speed Wind Tunnel facility. The droplet size of each of the nozzles with different airspeeds, spray pressures, and orientation was measured with a Sympatec Helos laser diffraction instrument. The droplet size spectra for each test were input in a spray dispersion model (AGDISP), which calculates the downwind drift expected from a typical aerial application scenario. As compared to the reference nozzle, the three spray nozzles reduced spray drift by 70-84 % as compared to the reference nozzle. The nozzles generated spray droplets with volume median diameters 60-80 microns larger than the reference nozzle. One of the aerial application industry's best management practices BMPs is to not spray directly on the downwind edge of a field. The spray swath near this edge is moved upwind i.e., offset by 1/2 to 1 swath width. When this BMP was combined with the drift reductions from the spray nozzles, the amount of drift reduction was slightly increased; however application efficiencies increased to 93-96 %. These results demonstrate the possibility of combining multiple drift reduction tech.
