“…In all the tests, the tracer used was tartrazine (Roha Europe, SLU, Torrent, Spain) at a tank concentration of 10 g L −1 . Tartrazine is a water‐soluble dye frequently used in this type of study,9, 20–24 as it offers a high recovery rate and high photostability 25. This dye is authorised in food both by the European Community (E‐102) and in the United States (FD&C Yellow No.…”

“…Positive results of using these modern nozzles corroborate experiments with fertilizing, in which it was stated that using the antidrift nozzle has a beneficial influence on foliar fertilizing of crops, especially in adverse windy conditions. Italian research, in which the antidrift nozzle was used successfully to protect grapevines, corroborates this as well (Balsari et al 2001).…”

Studies of three years (2007)(2008)(2009)) were conducted at Czesławice in southeast of Poland .The objects of research were the plants of the one cultivar of chrysanthemum: Dark Tripoli. The following agents were used for protection: Dithane NeoTec 75 WG, Sumilex 500 SC, Amistar 250 SC. The treatment was carried out with the use of two types of nozzles: standard RS-MM 110 03 and ejector type ID 120 03 C. Observation was carried out once a year: in October. The number and health status of plants were determined and diseased plants were collected for analysis. The percentage of plants with disease symptoms was estimated for each plot. The best health status and yield were noticed for Amistar 250 SC.KEYWORDS: chrysanthemum, biological efficacy, fine droplets, coarse droplets STRESZCZENIE W pracy przedstawiono wyniki doświadczenia polowego ochrony fungicydowej chryzantemy odmiany Ciemne Tripolis. Badania był prowadzone w gospodarstwie doświadczalnym w Czesławicach, położonych na południowym wschodzie Polski. Doświadczenie było prowadzone metodą blokową. Do ochrony roślin chryzantemy użyto trzech rodzajów fungicydów: Dithane NeoTec 75 WG, Sumilex 500 SC, Amistar 250 SC. Fungicydy były nanoszone metodą oprysku z wykorzystaniem dwóch rodzajów rozpylaczy szczelinowych. Rozpylacz standardowy MM 110 03 firmy (Marian Mikołajczyk), oraz rozpylacz antydryfowy eżektorowy ID 120 03C firmy (Lechler). Obserwacje stanu zdrowotności roślin przeprowadzano, co roku w październiku. Oceniano wysokość roślin, średnicę roślin i stopień porażenia. Najlepsze efekty ochrony odnotowano na poletkach gdzie był stosowany fungicyd Amistar 250C, bez względu na to, jakiego rodzaju rozpylaczem był nanoszony na rośliny.

“…Apart from the tracers mentioned above, environmentally friendly water‐soluble food dyes are also frequently used as tracers for spray deposition assessment. Tartrazine has been widely used as a tracer to measure spray deposition in various crops because it presents a high recovery rate and high photostability . Other food dyes including Green S, Erytrosine, Ponceau 4R, Indigo Carmine and Patent Blue have also been adopted as tracers.…”

BACKGROUND Quantification of spray deposition on a target crop is of vital importance to optimize pesticide application. In traditional determinations of spray deposition, a large amount of organic solvent is used to extract pesticides from the target crops. In this study, a water‐soluble food dye of Allura Red was developed as a tracer to determine pesticide spray deposition on a rice target crop. RESULTS The addition of Allura Red does not obviously alter the physicochemical properties of pesticides (viscosity, density and surface tension) and droplet spectra. An ultra‐performance liquid chromatography (UPLC) analytical method was developed and validated to determine the deposition amount of Allura Red on rice plants. Method accuracy and precision for Allura Red were found to be satisfactory with recoveries of 96.07% to 107.48%. To validate the method, comparative deposition analyses were carried out using representative systematic and non‐systematic pesticides (nitenpyram and chlorothalonil) under the same spraying scenarios using a Potter spray tower. Allura Red and pesticides showed comparable deposition under the same application conditions with ratios from 0.98 to 1.21. A field trial using an unmanned aerial vehicle sprayer further indicated that the deposition rates for Allura Red and nitenpyram on rice seedling were 13.04% and 11.07%, with corresponding relative standard deviation values (n = 5) of 16.39% and 18.79%. CONCLUSION A laboratory test and field trial confirmed that the developed method of using Allura Red as a tracer for spray deposition assessment is feasible and practicable. © 2019 Society of Chemical Industry
