Lead (II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O. It occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure.

Piperonyl butoxide (PBO) is a pale yellow to light brown liquid [1] organic compound used as an adjuvant component of pesticide formulations for synergy. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone. [2]

Piperonyl butoxide (PBO) is an organic compound used as a component of pesticide formulations. It is used for the treatment of head, pubic (crab), and body lice. Piperonyl butoxide is a synergist.

Piperonyl butoxide (PBO), is a pesticide widely used along with pyrethroids as grain protector and domestic insecticide [84]. PBO is capable of increasing the gene expression of CYP1A1, a cytochrome P-450 isoform and the most active enzyme catalyzing procarcinogens [85].

Piperonyl butoxide (PBO) is a human-made pesticide synergist. By itself, PBO is not designed to harm insects. Instead, it works with bug killers to increase their effectiveness. PBO is often combined with natural pyrethrins or human-made pyrethroids.

Nov 27, 2015 · Piperonyl butoxide (PBO) is an organic compound used as a component of pesticide formulations. It is used for the treatment of head, pubic (crab), and body lice. Piperonyl butoxide is a synergist. It has no pesticidal activity of its own, but acts to increase the activity of pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.

Jan 1, 1999 · This chapter discusses the principal physical and chemical characteristics of piperonyl butoxide (PBO) and gives descriptions of several analytical methods that are each applicable to differing use patterns.

Its molecular formula is C19H300S; it has a molecular weight of 338.4 g/mol. The chemical structure is shown in Figure 205.1. PBO is a colorless to pale-yellow liquid and is moderately stable in that it is resistant to hydrolysis, oxidation, and …

This chapter outlines the history of development of piperonyl butoxide (PBO) as an insecticide synergist. Piperonyl butoxide was invented and developed in the USA in response to fears for public health because of threat by insect vectors.
