Phytotoxicity of Whole Crop Forage Rice to Benzobicyclon

Abstract

서 론Benzobicyclon은 prenylquinone 생합성 경로의 phydroxyphenylpyruvate dehydrogenase (HPPD) 효소를 억제 하여 plastoquinone 및 alpha-tocoperol의 생합성을 저해하 며, 결과적으로 신엽의 백화현상을 일으켜 식물체를 고사 시킨다 (Barta and Böger, 1996;Garcia et al., 1999;Lee et al., 1997;Pallett et al., 1997).

Evaluation of weed control efficacy and crop safety of the new HPPD-inhibiting herbicide-QYR301

“…In conclusion, results obtained from both the greenhouse and field experiments revealed that QYR301 has good potential for weed control in paddy production system as a selective POST herbicide. Benzobicyclon and mesotrione cause significant damage to paddy depending on hybrids 47 , 48 and weeds are rapidly evolving resistance to multiple herbicides with various modes of action, such as propanil, quinclorac, ALS inhibitors, ACCase inhibitors and PSII inhibitors. With those challenges, QYR301, a novel HPPD-inhibiting herbicide, may be an effective and safe chemical agent to manage the herbicide resistance of some weed species in paddy fields.…”

Selectivity of Tefuryltrione between Rice and Eleocharis kuroguwai

“…Previous studies reported that HPPD inhibitor herbicides such as benzobicyclon and mesotrione caused significant damage to rice depending on rice cultivars Kim et al, 2014;Yang et al, 2014). Most of HPPD inhibitors caused greater damage to tongil (indica × japonica) rice than japonica rice, except for tefuryltrione, which is known to cause less damage than the other HPPD inhibitors regardless of cultivars (Kwon et al, 2012).…”
