Using plant circadian programs to optimize agrochemical use. [PDF]
New PhytolSummary Agrochemicals play an important role in maximizing agricultural yields. One class of agrochemicals is herbicides, which are used for weed control and to kill the top growth of certain crops before harvest. We examine the influence of plant circadian regulation on herbicide effectiveness to exemplify how knowledge of the circadian clock could be

Susceptibility of Phthorimaea absoluta (Meyrick) (Lepidoptera: Gelechiidae) to novel and established insecticides in Brazil: resistance survey, baseline, and implications for management. [PDF]
Pest Manag SciBaseline susceptibility of Phthorimaea absoluta to novel insecticides isocycloseram and tolfenpyrad was established in Brazil. Diagnostic doses were proposed for early resistance detection. Early tolfenpyrad tolerance and abamectin‐driven cross‐tolerance to isocycloseram via oxidases highlight cross‐resistance risks, emphasizing the need for routine ...
