Nano-sizing of the bioactive 1, 3, 4-thiadiazole derivatives, namely, 2-alkyl/alkenyl/heterocyclyl sulfanyl-5substituted-1, 3, 4-thiadiazoles revealed higher in vitro nematicidal activity against Meloidogyne incognita in laboratory with LC50 of 2.3–4.41 μg mL−1. Nano-sized bis-(5-amino-1, 3, 4-thiadiazole-2-sulfanyl methyl) methane was the most active with the highest nematicidal activity after 72 h with LC50 of 2.30 μg mL−1. Similar trend was observed in pot culture experiment against root knot nematode in tomato plant.
