Foliar application of benzovindiflupyr shows non-fungicidal effects in wheat plants.

Background: The fungicide benzovindiflupyr belongs to the class of succinate dehydrogenase inhibitors (SDHIs). Certain SDHIs have shown plant physiological effects, so-called secondary effects, that appeared to be related to the plant water status. Therefore, the effect of benzovindiflupyr on transpiration of leaves and whole wheat plants was studied under controlled conditions.

The invertebrate pharmacology of insecticides acting at nicotinic acetylcholine receptors.

The nicotinic acetylcholine receptor (nAChR) is a ligand-gated ion channel composed of 5 protein subunits arranged around a central cation selective pore. Several classes of natural and synthetic insecticides mediate their effect through interacting at nAChRs. This review examines the basic pharmacology of the neonicotinoids and related chemistry, with an emphasis on sap-feeding insects from the order Hemiptera, the principle pest target for such insecticides.

Identifying the presence of neonicotinoidresistant peach-potato aphid (Myzus persicae) in the peach-growing regions of southern France and northern Spain.

Background: The neonicotinoid class of insecticides is a key component of pest management strategies used by stone fruit producers in Europe. Neonicotinoids are currently one of the most important tools for control of the peach-potato aphid (Myzus persicae). Overreliance on neonicotinoids has led to the development of resistance through a combination of metabolic and target-site resistance mechanisms in individual aphids.
