Pesticide MRLs as Trade Barriers: Evidence From Vietnam's Coffee and Rice Exporters

Agribusiness, EarlyView.
ABSTRACT As tariffs have declined globally through bilateral and regional trade agreements, food safety standards have emerged as significant determinants of agricultural trade flows. This study examines the impact of maximum residue limits (MRLs) for five pesticides—Azoxystrobin, Chlorpyrifos, Chlorantraniliprole, Clothianidin, and Cyhalothrin—on ...

Synthesis and Insecticidal Activity of Lignan Analogs (III) [PDF]

Bioscience, Biotechnology, and Biochemistry, 1992
The influence of the 6-methoxy-2-methoxymethyl-3-(3,4-methylenedioxyphenyl)-1,4-benzodioxan-7-yl group on the insecticidal activity of haedoxans was studied by synthesizing an analog without the (methoxymethyl)methinoxy moiety of the benzodioxanyl group to test for its activity on the housefly.
