Calypso: A New Neonicotinoid Insecticide for Cotton and Several Other Crops

A. M. Wyman, R. J. Steffens, A. Elbert and J. Kuehnhold


 
ABSTRACT

Thiacloprid, N-[3-(6-Chloro-pyridine-3-ylmethyl)-thiazolidine-2-ylidene]cyanamide is a highly active, novel, insect control agent with broad spectrum efficacy against sucking insects at 0.025 to 0.25 lb ai/acre depending on crop, pest and application type. Five years of field studies revealed excellent control of important pests in cotton, pome fruit, vegetables, potatoes and various other crops. Besides aphids, leafhoppers, plant bugs, and whiteflies, it is also active against various species of beetles
(e.g. Leptinotarsa decemlineata, Anthonomus pomorum), and lepidoptera such as leaf miners, codling moth, pink bollworm, and others. Thiacloprid has excellent plant compatibility in all relevant crops.

Like imidacloprid, thiacloprid acts agonistically on the nicotinic acetyl choline receptor. As a result there is no cross resistance to conventional insecticides such as pyrethroids, organophosphates, and carbamates and consequently, thiacloprid will fit well into resistance management strategies. Thiacloprid is an acute contact and stomach poison with systemic properties.

Thiacloprid has a favorable environmental profile with a short half-life in soil, and good margins of safety for birds, fish species, and many beneficial arthropods. The low toxicity to bees also allows its application during the blossom period of bee-attractive crops. Due to its low acute toxicity to mammals the product is safe for operators and consumers.
