Root-knot nematodes (RKNs) are a vital pest that causes significant yield losses and economic damage to potato plants. The use of chemical pesticides to control these nematodes has led to environmental concerns and the development of resistance in the nematode populations. Endophytic fungi offer an eco-friendly alternative to control these pests and produce secondary metabolites that have nematicidal activity against RKNs.

- The Agriculture Research Center's Sakha Agriculture Research Station conducted a study on cotton genetics between 2016 and 2018, selecting superior plants from F generations produced by crossing Giza 94 and Suvin.
- They found that over time, the mean values of traits in the cotton population increased, with F generations showing higher genetic and phenotypic variance compared to subsequent generations, emphasizing the role of genetics over environmental factors.
- The research identified specific families (9, 13, 19, 20, and 21) as the best genotypes for yield traits, indicating their potential for developing high-yield cotton varieties in future breeding programs.

We evaluated 211 vegetable samples, collected from supermarkets between March 2018 and September 2018, for a total of 80 different pesticides using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) after extraction with a multi-residue method (the QuEChERS method). The results were assessed according to the maximum residue limit (MRL) provided by European regulations for each pesticide in each commodity.
