Butachlor is an extensively applied herbicide in paddy fields. However, concerns have been raised about its potential adverse effects on the biochemical and physiological processes of non-target plants. In the present investigation, butachlor-induced toxic effects in two rice cultivars, Zhejing 88 (ZJ 88) and Xiushui 134 (XS 134), treated with different butachlor treatments were evaluated. A significant decrease in growth rate, pigment concentration, and chlorophyll fluorescence and alternations in chloroplast structures were observed in both rice cultivars at higher treatment levels. The malfunctioning of antioxidant enzymes, the higher uptake of butachlor, and the downregulation of the putative fatty acid elongase gene suggested severe oxidative damage, which was also indicated by enhanced reactive oxygen species (ROS) formation (H 2 O 2 , O À 2 ), lipid peroxidation, and electrolyte leakage and reduced total soluble protein levels in cultivar ZJ 88 than in cultivar XS 134. However, higher proline accumulation and pyrroline-5-carboxylate synthase and GABA-transaminase transcript levels in ZJ 88 suggested their ameliorative role under butachlor-induced oxidative stress in the sensitive cultivar. In contrast, the stimulated activation of antioxidant enzymes, glutathione, soluble sugars, and phenolics played a vital role in protection against butachlor stress in cultivar XS 134. Thus, butachlor-induced oxidative stress tolerance in the resistant cultivar (XS 134) is related to the enhanced activation of different isoforms of antioxidant enzymes and a reduced uptake of butachlor compared to the sensitive cultivar (ZJ 88). The present work provides valuable insights into butachlor-induced toxicity in rice plants.

“…At 100 lM concentration, butachlor was found to inhibit all the above mentioned processes. At a concentration of 50 lM, the protein and RNA synthesis of rice (Oryza sativa L.) and barnyardgrass (Echinochloa crusgalli L.) root and shoot segments were inhibited (Chang et al 1985).…”

Butachlor, a chloroacetanilide herbicide, used extensively all over the world as pre-emergence control of unwanted weeds. As a consequence, concerns about its potential adverse effects on the ecosystem and toxicity have risen. Several techniques have been used or are being investigated for effective removal of butachlor from the contaminated sites. This review reports the various toxicological studies conducted so far on the butachlor and the removal technologies available for its decontamination for better understanding. A new insight was also proposed after critical analysis of the merits and demerits of the removal technologies elucidated in the literature. An attempt was made to summarize the currently available analytical techniques reported for determination of butachlor in the environmental samples.

“…It seems that BUC-treated seedlings have lower protein contents compared to those treated with BCB. This can be explained by the action of butachlor, a component of BUC which directly inhibits protein synthesis (Chang et al, 1985). A total of 17 free amino acids were detected in E. crus-galli shoots ( Table 5).…”

Alternatives to commercial chemical herbicide are currently being searched and tested due to the numerous adverse effects of commercially available herbicides to the environment. Barnyardgrass (Echinochloa crusgalli) is an important weed species around the world, especially in paddy rice fields. This study focuses on the favorable effects of mixing pyroligneous acids with commercial liquid herbicides. Seedlings were transplanted and grown under greenhouse conditions. The effect of treatment time or leaf-stage on herbicide-pyroligneous acid efficacies was checked, coupled with isolation and quantification of biochemical compounds. Results revealed that herbicide treatment at early post emergence (2~3 leaf stage) of Echnochloa crus-galli leads to effective control. Both liquid herbicides affected fatty acid, protein, and amino acid syntheses as reflected on their contents. The influence of wood vinegar (WV) or rice vinegar (RV) on these compounds was not thoroughly verified due to lack of information on the pyroligneous products. We observed that mixing WV or RV with BCB (bentazone + cyhalof-butyl) gives more favorable results than BUC (butachlor + clomazone), mixed with WV or RV. The result would indicate the potential of mixing pyroligneous acid in reducing herbicide application rate.
