“…five days for diazinon; four days for permethrin, and 13 days for chlorpyrifos) before distributing the crops into the markets. As the previous studies showed, considering preharvest period on the fruits and vegetables decreased the level of different pesticide residues (6,(19)(20)(21)(22)(23)(24)(25). As a general trend, the current study showed that the detected pesticides on tomato and cucumber were almost similar to those of some previous studies (26-28), but gradually higher than the results of the study by Abbassy (19).…”

Background: The organophosphorus pesticides are still applied in some developing countries including most regions of Iran. It is important to make sure that the level of pesticide residues at the time of harvesting vegetable crops (e.g. tomato and cucumber) is assessed in order to control that their levels are within the permissible limit in the domestic as well as overseas markets; and most importantly the governments should ban the application of such compounds. Regarding the increasing consumption of pesticides in agriculture, the current study aimed at determining the amount of pesticide residues in crops such as tomatoe and cucumber to ensure that Codex maximum residue limit (MRL) alimentarius is not violated. Methods: A simple multiresidue method, using gas chromatography-mass spectrometry (GC-MS) and solid phase extraction, was employed to detect the pesticides with a sufficient extraction method. Results: The lowest level of pesticide residues were concerning carbaryl, fenpropat, and endosulfan in cucumber samples selected from greenhouses and fields with 11.1%, while the highest level was concerning diazinon in cucumber samples of the fields with 55.5%. Carbaryl and permethrin showed the high residue means of 0.37 and 0.72 µg/g in tomato and cucumber samples, respectively. Conclusions: Vegetables and fruits with a high level of pesticide residues, which particularly violated the MRL, are sold in markets of Tehran, Iran. Therefore, it is suggested that the application of pesticides on fields and greenhouses be controlled and their residue levels be measured using the multiresidue method before distribution. The current study findings showed that the multi-residue method with GC/MS could detect a large number of pesticide residues at the same time with high accuracy. Therefore, it is recommended that this method be employed for all vegetables and fruits in order to assess their pesticide residue levels before reaching the markets.

“…Chlorantraniliprole, [3-bromo-N-[4-chloro-2-methyl-6-[(methyl amino) carbonyl] phenyl]-1-(3-chloro-2-pyridinyl)-1H-pyrazole-5-carboxamide], is a new anthranilic diamide pesticide developed by DuPont Crop Protection ( Fig 1 ) [ 22 ]. As described previously, it has a novel mode of action called ryanodine receptor activators which can lead to the depletion of intracellular calcium stores and cause impaired muscle regulation, paralysis and insect death [ 22 , 23 ]. The pesticide exhibits remarkable insecticidal efficacy and mammalian safety, and has been widely used for pest control in agriculture [ 24 – 26 ].…”

Poorly water-soluble compounds are difficult to develop as pesticide products and face great challenges in water-based and environmentally friendly formulation development. In this study, high pressure homogenization combined with lyophilization was adopted to prepare the solid nanodispersions of chlorantraniliprole with poor solubility and high melting point. The mean particle sizes of the solid nanodispersions with different pesticide contents were all less than 75 nm, even when the content was up to 91.5%. For the 2.5% chlorantraniliprole solid nanodispersion with the mean particle size of 29 nm, the suspensibility and wetting time in water were 97.32% and 13 s, respectively. The re-dispersibility and wettability were superior to those of conventional water dispersible granules. The retention on the rice leaf of 18.7 mg/cm2 was 1.5 and 3 times that of commercial aqueous suspension concentrate and pure water. The bioassay result to diamondback moths indicated that the toxicity of the solid nanodispersion was 3.3 and 2.8 times that of technical and aqueous suspension concentrate, respectively. Moreover, the solid nanodispersion has the advantages of total avoidance of organic solvents, significant reduction of surfactants and feasibility of obtaining high concentration nanoformulations. The solid nanodispersion is an attractive candidate for improving pesticide solubility and efficacy, and its application in crop production will reduce both residues in food and environmental pollution of pesticide.

“…Tomato, Solanum Lycopersicum L. (Solanaceae), is grown throughout the globe and its berry (fruit) constitutes an important part of human diet (Gupta et al, 2011). In Egypt, tomato is cultivated in about 221 thousand hectares which represent about 34 % of the average area of vegetables, while the fruits are basic component of the daily diet (Malhat et al, 2012a). Chemical pesticides are often applied for plant protection of the crop (Singh et al, 1980;1989;Awasthi, 1986).…”

Summary A high performance liquid chromatography with the photodiode array detector (HPLCDAD) analytical method was developed to determine the residue levels and investigate the dissipation pattern and safety use of methomyl in tomato and soil. Methomyl residues were extracted from tomato and soil samples with ethyl acetate. The extract was cleaned up with the QuEChERS method. The results showed that the average recoveries were in the range of 87.1-94.5%, with RSD of 6.9-11.2%. Limits of detection (LOD) and quantification (LOQ) were 0.005 and 0.007 mg/kg, respectively. The residue levels of methomyl were best described to first order rate kinetics and half-lives ranged from 1.34 to 1.8 days in tomato and soil, respectively. The theoretical maximum residue contributions for methomyl on tomato were found to be less than the maximum permissible intake values even on zero days, therefore consumer health risks are minimal at the recommended dose on tomato.
