AbstractEthyl 1‐fluoromethyl‐5‐(4,6‐dimethoxypyrimidin‐2‐ylcarbamoylsulfamoyl)pyrazole‐4‐carboxylate 1b, a new fluoromethyl analogue of the herbicide pyrazosulfuron‐ethyl la, was prepared from ethyl 1‐fluoromethylpyrazole‐4‐carboxylate 4b. The difluoromethyl and trifluoromethyl analogues 1c,d were also synthesized from ethyl pyrazole‐4‐carboxylate 2 ...

The objective of this research was to investigate the effect of wheat and rice biochars on pyrazosulfuron-ethyl sorption in a sandy loam soil. Pyrazosulfuron-ethyl was poorly sorbed in the soil (3.5-8.6%) but biochar amendment increased the herbicide adsorption, and the effect varied with the nature of the feedstock and pyrolysis temperature.

Dissipation and fate of ready mix combination of pyrazosulfuron-ethyl and pretilachlor in rice field
Indian Journal of Weed Science, 2018Application of ready-mix herbicides containing two active ingredients in rice to manage broad group of weeds is in practice currently. Among different ready mix formulations, one comprising pyrazosulfuron-ethyl and pretilachlor have been recently registered in India. Though, the persistence of each herbicide in soil under rice as single formulation was

Abstract Burning of crop residues after harvest is a quick, cheap and an easy way to manage the large quantities of agricultural biomass for timely preparation of the field for next crop. Conversion of the crop harvest residues into biochars and incorporating them back in the same field can address the issue of land clearing, waste utilization and ...

Weed control by pyrazosulfuron-ethyl and its influence on yield and economics of transplanted rice
Indian Journal of Weed Science, 2018A field experiment was conducted on a silty clay loam soil at Palampur, Himachal Pradesh during Kharif 2016 and 2017 to assess pyrazosulfuron-ethyl as an alternative herbicide to manage weeds in transplanted rice. Ten treatments comprised of company released sample of pyrazosulfuron-ethyl at 10, 15, 20 and 30 g/ha was compared to its market sample at ...
