Fosthiazate
Based on 1 Customer Validation
Fosthiazate is an inhibitor of acetylcholinesterase (Acetylcholinesterase, AChE). Fosthiazate exhibits significant nematicidal activity and systemic insecticidal activity. Fosthiazate is applicable to studies on plant-parasitic nematodes, root-knot diseases, agricultural pests, as well as the ecotoxicology and environmental behavior of organophosphorus compounds.

Biological Activity
Fosthiazate (both (+) and (-) isomers) exhibits weak inhibitory effects on acetylcholinesterase in the head of house flies, with an IC50 > 10-3 M[1].
The degradation half-life of fosthiazate (5 μg/g soil; 20 °C; up to 60 days) is 17.7-46.8 days in non-sterilized soil, while it is 28.4-87.7 days in sterilized soil, indicating that its degradation in soil involves both chemical and microbial processes[2].
Fosthiazate (2-25 μg/mL; 24 h) shows weak adsorption to San Emigdio sandy loam, Arlington sandy loam, and Waukegan silty clay loam, with its linear adsorption coefficient (Kd) ranging from 0.10 to 0.89[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Fosthiazate (2-20 mg/kg soil; 14 or 28 days) reduces AChE activity in Eisenia fetida in a dose-dependent manner and alters the expression of AChE-related genes[3].
Fosthiazate (7.9-31.6 mg/pot; applied to the root zone; 48 h after nematode inoculation) reduces the numbers of root galls, egg masses and nematode eggs in chili peppers infected by M. enterolobii, with the maximum reduction rates of 58.6%, 64.7% and 83.7% respectively observed in Trial 1[4]
Fosthiazate (3 kg a.i./ha; 2 applications; at transplanting and 3 months later) reduces root galls and egg counts by 39.8% and 80.1%, respectively, in the 'Super Hot' pepper cultivar, and by 59.6% and 67.5%, respectively, in the 'Amphawa Hot Pepper' cultivar, in natural root-knot nematode-infested pepper fields in Ubon Ratchathani[4].
