“…Tebuconazole (TEB) is a relatively broad‐spectrum 1,2,4‐triazole fungicide against fungal diseases on cereals, fruits, vegetables, and leaf spot diseases (Yan et al, 2015). The half‐lives of TEB were ~6 days in fruit (Dong & Hu, ) and days to almost 600 days in soil (Strickland, Potter, & Joo, ; Soudamini.,2014; Cui et al, ). The compound TEB has a high potential for leaching and might be transferred to the environment, which poses a potential risk to the environment and human health (Caldas, Demoliner, Costa, D'Oca, & Primel, ).…”

The transgenerational reproductive and developmental toxicity of tebuconazole (TEB) in Caenorhabditis elegans was investigated over five generations (P0 − F4). Only parental C.elegans (P0) were exposed to TEB (0, 0.01, 0.1, 1, and 10 μg/L) for 24 h and the subsequent offspring (F1-F4) were grown under TEB-free conditions. TEB exposure caused dose-dependent reproductive defects and developmental impairments in C.elegans. In the P0 generation reproductive defects were observed such as:reduced brood size and embryo hatchability, prolonged generation time, retarded gonadal development, and slower germline proliferation, even at 0.01 μg/L, together with developmental toxicity with significant reduced body length and narrowed body width at 10 μg/L. Additionally, the brood size significantly reduced in F2, which began to recover from F3, but was still lower than the control in F4. The proportion of abnormalities increased significantly in F2 and reduced from F3, but was still higher than the control, suggesting that TEB could have cumulative potential and be passed to offspring through parental exposure. Furthermore, exposure to TEB (10 μg/L) in P0 significantly reduced the body length in F1, which began to recover from F2, and was the same level as the control in F4. There was a concentrationdependent increase in body width in F1-F4, with a significant increase only observed in F1 at 10 μg/L. Thus, parental exposure to TEB induced transgenerational defects in both reproduction and development, emphasizing the significance of considering bio-toxicity over multiple generations to conduct accurate assessment of environmental risks of toxicants.

Field and laboratory experiments were conducted to study the residues and dissipation of Fluopyram, a succinate dehydrogenase inhibitor (SDHI) and tebuconazole, demethylation inhibitor (DMI) used for the control of powdery mildew and Anthracnose diseases in grape. Residues of fluopyram dissipated with a half life of 4.04 and 5.18 days, at recommended and double dose, respectively. For tebuconazole, the half life values recorded were 4.75 and 5.42 days, respectively. The residues reached below quantification limit (BQL) on 10 th and 15 th day, in both the fungicides at recommended and double the recommended dose, respectively, which suggests a Pre-Harvest Interval (PHI) of 7.76 and 9.91 days for fluopyram and tebuconazole, respectively when applied at 75 g a.i./ha and 150 g a.i./ha.

“…According to Patel et al, 6 half life of fluopyram was 8.85 and 9.12days, respectively in recommended and double dose. Dong & Hu 15 showed half life of 6.48days for fluopyram in watermelon. In chilli, Saha (2016) 5 found a half life of 1.161 and 1.241days for single (100g a.i./ha) and double (200g a.i./ha) application rate.…”
