Tuned S-Scheme Cu2S_TiO2_WO3 Heterostructure Photocatalyst toward S-Metolachlor (S-MCh) Herbicide Removal

Cross-resistance to prosulfocarb + S-metolachlor and pyroxasulfone selected by either herbicide in Lolium rigidum.

BACKGROUND Weeds can be a greater constraint to crop production than animal pests and pathogens. Pre-emergence herbicides are crucial in many cropping systems to control weeds that have evolved resistance to selective post-emergence herbicides. In this study we assessed the potential to evolve resistance to the pre-emergence herbicides prosulfocarb + S-metolachlor or pyroxasulfone in 50 individ...

Gentry ’ s SWHE Scheme

We briefly recall Micciancio’s “cleaned-up version” of GGH cryptosystems [GGH97, Mic01]. The secret and public keys are “good” and “bad” bases of some lattice Λ. More specifically, the keyholder generates a good basis by choosing Bsk to be a basis of short, “nearly orthogonal” vectors. Then it sets the public key to be the Hermite normal form of the same lattice, Bpk def = HNF(Λ(Bsk)). A cipher...

Biodegradation of an s-triazine herbicide, simazine

Two types of simazine-degrading microorganisms were isolated from soil samples where the herbicide had been spread with the enrichment culture using simazine as the sole carbon and nitrogen source. A fungal strain, DS6F, identified as Penicillium steckii, is the first simazine-degrading fungus ever reported. Ž Simazine was gradually degraded by P. steckii DS6F in the mineral medium containing s...
