“…Our finding agree with (9-11), The residual levels of AVMs in paprika in a field experiment from one day to seven days after the last application decreased from 18.40 to 7.59 μg/kg. The half-life (T1/2) of AVMs in paprika was 1.47 days (9). Degradation of abamectin on date palms, grown in Saudi Arabia was studied during the post-harvest interval (PHI) under the local weather and soil conditions.…”

An effective analytical method for the residue analysis of a novel acaricides abamectin and its dissipation in tomato were studied. Abamectin residues were extracted from tomato samples and the extract was cleaned up according to QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method and determined by high-performance liquid chromatography with photo diode array detector (HPLC-DAD). At fortification levels of 0.1, 0.5, and 1.0 mg/ kg in tomato, it was shown that recoveries ranged from 89.4 % to 95.6 %. The limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.02 and 0.01 mg/ kg, respectively. The dissipation half-life time of abamectin residues in tomato was 2.4 days. According to maximum residue limit (MRL) 0.5 mg /kg, the pre harvest interval (PHI) of abamectin on tomato was 8 days after the treatment. Based on the results of this study and the relevant residue regulation, abamectin residue levels will be acceptable when applied to tomato in Libya.

In this study, a fast, concise and reliable ultra-high performance liquid chromatography-fluorescence (UHPLC/FLD) detection method for simultaneous quantification of avermectins (AVMs), including avermectin (AVM), ivermectin (IVM), emamectin (EMM), moxidectin (MOX) and doramectin (DOR) in six aquatic foods was established. Based on the QuEChERS pretreatment method, the samples were extracted with 0.2% (v/v) ammonia acetonitrile. N-methyl imidazole mixed with acetonitrile (1:1, v/v) and trifluoroacetic anhydride with acetonitrile (1:2, v/v) were used as derivatization reagents. The mobile phase consists of acetonitrile and water with a flow rate of 1.0 mL/min. An Infinity Lab Poroshell 120 EC-C18 column was used for optimum chromatographic separation of target analytes at 40 °C; the excitation and emission wavelengths were set at 365 nm and 465 nm, respectively. In six kinds of aquatic foods, the limits of detection (LODs) of AVM, IVM, EMM, MOX, and DOR were 2.7 μg/kg, 1.8 μg/kg, 2.1 μg/kg, 1.2 μg/kg, and 2.7 μg/kg, respectively, and the limits of quantification (LOQs) of AVM, IVM, EMM, MOX, and DOR were 5 μg/kg, 4.5 μg/kg, 4.5 μg/kg, 3.5 μg/kg and 5.0 μg/kg, respectively. The recoveries were all above 85.38% when the samples were spiked with the target compounds at the concentration level of 5, 10, 50, and 100 μg/kg. The intra-day and inter-day relative standard deviations (RSDs) were all less than 15%. This method considers the requirements of sensitivity, accuracy, and economics of the instrument.

“…Avermectins in paprika had a half-life of 1.47 days and a quantitation limit of 2 μ/kg. (Gupta et al, 2015;Xie et al, 2006) investigated abamectin residues in cabbage at standard and double concentrations of 14.4 and 28.8 g a.i. / ha, respectively, and found that initial abamectin residues in cabbage from the two treatments were 0.495 and 0.773 mg/kg, respectively, and that both treatments reached below the detectable limit (BDL) on the third day.…”

Field trials were conducted in El-Salhia, Sharkia governorate, to assess the effectiveness of insecticides (imidaclopride, lambdacyhalothrin, and abamectin) against the two-spotted spider mite, Tetranychus urticae, on cucumber crops. The trial used a randomised complete block design (RCBD) with three treatments: T1: abamectin, T2: lambda-cyhalothrin, T3: imidaclopride, and control, which was repeated three times. At varied harvest intervals of (2h), 1, 3, 5, 7, 9-, 11-, 13-, and 15days following insecticide applications, residues and abamectin dissipation were measured. The insecticide's persistence, dissipation, half-life value, and safe harvest interval in cucumber were estimated. Additionally, the effects of abamectin residues on various quality indices (total soluble sugars, glucose, acidity, total soluble solids, ascorbic acid, -carotene, dry matter, and protein) were assessed in the last three samples (7 and 15 days after applications). The results revealed that all the treatments reduced the two-spotted spider populations. Furthermore, the results showed that the treatments sprayed with abamectin gave the highest reduction percentage (96.32%), followed by lambda-cyhalothrin (92.22%) and imidaclopride (76.93%). The halflife (t12) values in cucumber fruits were 2.99 days, and the loss percentages of initial deposits in cucumber fruits were 8.96 mg/ kg. In conclusion, we encourage farmers to use abamectin according to the Ministry of Agriculture recommendation in combating T. urticae, in integrated pest management, as cucumbers can be safely consumed after 7 days of abamectin treatment.
