In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant ADAMA Agriculture BV on behalf of ADAMA Makhteshim Ltd submitted a request to the competent national authority in Denmark to modify the existing maximum residue levels (MRL) for the active substance tau-fluvalinate in tomatoes and watermelons. The data submitted in support of the request were found to be sufficient to derive an MRL proposal for tomatoes. For watermelons, a change of the MRL recently set in the EU legislation is not required. Adequate analytical methods for enforcement are available to control the residues of tau-fluvalinate in the commodities under consideration. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the intended uses of tau-fluvalinate according to the reported agricultural practices is unlikely to present a risk to consumer health. The risk assessment shall be regarded as indicative.

During the field visits in growing season of 2022 in Dammam Region of Saudi Arabia, begomovirus-like symptoms including leaf curling, leaf cupping, leaf distortion, vein thickening and reduced leaf size were observed in squash and cucumber fields. Twenty-five samples were collected from each crop and PCR amplification was done using general diagnostic begomovirus primers (AC-1048/AV-494 and Begomo I/Begomo II). The obtained results showed desired sized amplified DNA fragments (550 bp and 1.

Three fluorescent bacterial strains, K1, K13 and K18, were obtained from watermelon () foliage symptomatic of bacterial leaf spot of cucurbits in Florida. The strains underwent phenotypic characterization, including LOPAT (levan production, oxidase activity, pectolytic activity on potato, arginine dihydrolase production and hypersensitive response (HR) on both tobacco and tomato) and pathogenicity testing on watermelon and squash seedlings. Whole-genome sequencing of the isolates was performed, and multi-locus sequence analysis (MLSA) utilizing housekeeping genes , , and placed the isolates into two distinct clades within the genus.

The regulation of non-climacteric fruit ripening by the transcription factor NON-RIPENING (NOR) is poorly understood. Here, we identified that the NOR homolog in the non-climacteric fruit watermelon (Citrullus lanatus) was located within the selective sweep and sweetness quantitative trait locus that was selected during domestication from landraces to cultivars. ClNOR knockout substantially delayed fruit ripening, and the fruits of the knockout plants had lower abscisic acid (ABA) levels, lighter colored flesh, and were less sweet compared to wild type.
