The Effect of Environmental Factors on the Herbicidal Activity of Pyrazosulfuron-ethyl under Paddy Conditions.

Journal of Weed Science and Technology, 1994
The effect of environmental factors on the herbicidal activity of pyrazosulfuron-ethyl was examined by pot tests in a greenhouse. Uptake site of pyrazosulfuron-ethyl in Cyperus serotinus Rottb. was determined by two application methods, i. e., surface water application for shoot uptake and soil incorporation for root up-take.

Weed Response to Different Tank-Mix Herbicide Combinations and its Impact on Winter Rice Performance in Zero Till Non-Puddled Condition

Fundamental and Applied Agriculture
Tank-mixture of two or more chemical groups of either pre- or post-emergence herbicide might play a vital role to manage weeds of a diversified community more effectively than their single or sequential application.

Weed Management in Dry-Seeded Fine Rice under Varying Row Spacing in the Rice-Wheat System of Punjab, Pakistan

Plant Production Science, 2014
Direct seeding can curtail water and labor inputs involved in rice production; nevertheless, its large-scale adoption is impeded by heavy weed infestation.

Bio-efficacy of pyrazosulfuron ethyl 10% wp against weeds in transplanted rice

Journal of Applied and Natural Science, 2017
An experiment was conducted during Kharif 2012 and 2013 at Agricultural Research Station, Dhadesu-gur, University of Agricultural Sciences, Raichur, Karnataka, India, to evaluate the phytotoxicity and bio efficacy of pyrazosulfuron ethyl 10 % WP (wettable Powder) @ 5, 10, 15 and 20 g a.i./ha against the weeds in transplanted rice.

Environmental dynamics and mobility of pyrazosulfuron-ethyl herbicide in diverse soils and their amendments

Journal of Environmental Science and Health, Part B
The nonionic herbicide pyrazosulfuron-ethyl (PYZE) has low water solubility, yet residues are frequently found in surface and groundwater, raising environmental concerns. Its soil binding and release depend on soil composition. This study examines how soil types influence PYZE sorption–desorption behavior.
