Contribution des méthodes de lutte mécanique au désherbage intégré des grandes cultures oléagineuses
Oléagineux, Corps gras, Lipides, 2009 The integrated approach of weed management refers to a combination of direct and indirect methods in order to limit chemical applications. In oilseed rape, sunflower and soybean, mechanical weed control can be an alternative or a complement to herbicides

Three mechanical weed control techniques in spring cereals
Agricultural and Food Science, 2000 An inter-row hoe suitable for cereals was developed for the study, and field experiments were conducted to compare inter-row hoeing with weed harrowing, rotary hoeing and chemical control. The treatments were performed once during the growing season. Inter-row hoeing was studied at row spacings of 180 mm and 250 mm.

Diterpenoid Diversity across Land Plants
Helvetica Chimica Acta, EarlyView.Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

International Journal of Cancer, EarlyView.What's New? Esophageal squamous cell carcinoma (ESCC) incidence varies worldwide, suggesting that local environmental and dietary factors are influential. In coastal southeastern China, food products derived from small filter‐feeding fish are important dietary components, though their consumption increased ESCC risk.

Comparison of weed management methods in organic carrot
International Journal of Horticultural Science, 2003 14 combinations of mechanical and also physical (thermal) weed management techniques are compared for organic growing of carrot. Crop of our weed management research is carrot because of its difficulties in weed management (long growing period, poor weed

Mechanical Weed Control Methods on Soybean Field
Journal of Weed Science and Technology, 1974 畑雑草の防除の効率化をはかるために, 牽引型除草機の作業条件と作業体系とを組合わせて, 機械除草の限界と雑草の種類組成ならびに大豆の生育・収量に及ぼす影響について検討した。1) 雑草本数は効果的な条件を連続して適用すると経時的に減少するが, 除草効果を高めるには, 初期に作用の大きい条件を適用する方式と経時的に作用を増す方式があることが判った。2) ホー除草に比べて機械除草区の雑草本数は0.7～4.9倍, 雑草重は1.8～16.2倍であり, 除草爪の作用深さが増すにしたがって雑草量は減少した。最適作業条件は「作用位置5cm-作用深さ8cm-連続3回掛け」の条件である。3) 除草作用は播種25, 45日後の作業で大であり, 作業前に比較して雑草本数はそれぞれ68～81%, 43～84%に減少した。4)

JSFA reports, EarlyView.Abstract Background Bacterial wilt of enset (Ensete ventricosum (Welw.) Cheesman) is a severe disease caused by Xanthomonas campestris pv. musacearum, resulting in complete crop failure and considerable damage. This study assessed the biochemical responses of two enset clones (one resistant and one susceptible) when inoculated with the pathogen and ...
