Introduction:
Propargite was first registered in the United States in 1969 for control of mites on a variety of field, fruit, and vegetable crops, as well as ornamental. It is manufactured by Uniroyal Chemical.
Propargite is an organic sulfuric insecticide, with a characteristic odor of sulfur gas. It has low toxicity, broad spectrum, contact and fumigation, no internal absorption and osmotic thermal conductivity. It is specific for adult spiders, nymph mite and young mite.
Propargite belongs to toxic group III. It is very little toxic to humans and livestock, less toxic to bees and spiders that are natural predators, but it is relatively toxic to fish and aquatic animals.
Physical and chemical properties:
CAS No: 2312-35-8
IUPAC: 2-(4-tert-butylphenoxy)cyclohexyl prop-2-yne-1-sulfonate
Appearance: amber viscous liquid
Molecular formula: C15H18N6O6S
Molecular weight: 410.4 g/mol
Density: 1.10 g/cm3
Fully miscible with hexane, toluene, dichloromethane, methanol and acetone
Mechanism of action:
Propargite works by inhibiting the development and function of insects reproductive organs, reducing their ability to reproduce and grow.
Propargite also affects cholinergic ganglionic, a type of ganglioside that plays a role in nerve signaling in the insect nervous system. Acting on it can help cause disorders in the insect's nervous system.
Propargite causes respiratory metabolic disorders, thus affecting the metabolism of insects.
Application:
Propargite is used to control a variety of caterpillars and spider mites in crops such as rice, cotton, coffee and tomatoes.
Propargite is also used to control beetles such as stink bugs, seafood beetles and penguin beetles and red spiders. on crops, rice and fruit trees.
