Mode of Action of Insecticides: (i) Systemic poison: Such type of chemicals or poisons are absorbed into plants and trans-located to whole plant system internally. [13,15–17]. e.gGesaprim Selective –a herbicide that kills small weeds and seeds but leave the crop unharmed e.g Gesagard. They are used primarily to control pests that infect cultivated plants or to eliminate disease-carrying insects. Respiration Several insecticides are known to interfere with mitochondrial respiration by the inhibition of electron transport and/or oxidative phosphorylation. The first book in two decades to address this multi-faceted field, The Toxicology and Biochemistry of Insecticides provides the most up-to-date information on insecticide classification, formulation, mode of action, resistance, metabolism, ... The book also explores how resistance to pesticides develops, how resistance can be used to illustrate the theory of evolution, and how it can be used to produce herbicide-resistant crop plants. In the aim of characterizing the nAChR subunits involved in the pharmacological IRAC is a techni-cal working group within the Global Crop Protection Federation (GCPF). In 1984 nithiazine's mode of action was found to be as a postsynaptic acetylcholine receptor agonist, the same as nicotine.
