Herbicides adversely affect both the target plant and its environment. In this study, Helianthus annuus L. cv. “Oliva CL” was treated post-emergence with 0.3 to 3.1 mM quizalofop-p-ethyl. The peroxidase activity (POD), ascorbate peroxidase activity (APX), lipid peroxidation, pigment system and total phenolic content were then determined on the 1st, 5th, 10th and 15th days following treatment. T...

Biotechnology has enriched the strategy set available to crop managers. Suppose a manager faces a decision between applying a pre-emergence pesticide or applying nothing at all. The advent of pesticide tolerance traits in plants admits the possibility of a state-contingent post-emergence application of pesticide. The innovation adds value in large part because it provides the manager with the o...

An agronomic investigation conducted at Agricultural Research Station, Mandor, affiliated with Agriculture University, Jodhpur, Rajasthan, during Kharif season 2018. experimental design utilized a randomiz...

S-[(4-chlorophenyl) methyl]diethylcarbamothioate General information This document reviews the environmental fate and environmental effects of the thiocarbamate herbicide, thiobencarb {S–[(4-chlorophenyl) methyl] diethylcarbamothioate (C 12 H 16 ClNOS)}. Thiobencarb, also referred to as benthiocarb was developed by Kumiai Chem. Ind. Co. Ltd and introduced in the market in 1970 (Ishikawa, 1981)....

poaceous weeds are prolific and competitive in winter crops, but they are more insidious in wheat due to their similar morphology and growing requirements. herbicides are effective and efficient tools of weed management, however, they are vulnerable to resistance, and herbicides with different modes of action might check the dominance of a particular weed flora. the current study was undertaken...
