Associations of a second-generation anticoagulant with an antibiotic and/or vitamin D are considered to be effective even against most resistant strains of rodents, though some second generation anticoagulants (namely brodifacoum and difethialone), in bait concentrations of 0.0025% to 0.005% are so toxic that resistance is unknown, and even ...
Zinc phosphide (Zn 3 P 2) is an inorganic chemical compound.It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. [5] Zn 3 P 2 is a II-V semiconductor with a direct band gap of 1.5 eV [6] and may have applications in photovoltaic cells. [7]
Phosphine is an attractive fumigant because it is lethal to insects and rodents, but degrades to phosphoric acid, which is non-toxic. As sources of phosphine, for farm use, pellets of aluminium phosphide (AlP), calcium phosphide (Ca 3 P 2), or zinc phosphide (Zn 3 P 2) are used. These phosphides release phosphine upon contact with atmospheric ...
Tributylphosphine reacts with oxygen to give the corresponding phosphine oxide (here tributylphosphine oxide): 2 P(CH 2 CH 2 CH 2 CH 3) 3 + O 2 → 2 O=P(CH 2 CH 2 CH 2 CH 3) 3. Because this reaction is so fast, the compound is usually handled under an inert atmosphere. The phosphine is also easily alkylated.
Rodentology is a branch of mammalogy for the study of rodents by a rodentologist. [1] The scientific group of rodents would include, but is not limited to, mice, rats, squirrels, etc. From the perspective of zoology , it investigates the behaviour, biology and classification of various rodent species.

The toxicity of aluminium phosphide is attributed to the liberation of phosphine gas, a cytotoxic compound that causes free radical mediated injury, inhibits vital cellular enzymes and is directly corrosive to tissues. The following reactions release phosphine when AlP reacts with fluids in the body: AlP + 3 H 2 O → Al(OH) 3 + PH 3, and
Compounds related to phosphine oxides include phosphine imides (R 3 PNR') and related chalcogenides (R 3 PE, where E = S, Se, Te). These compounds are some of the most thermally stable organophosphorus compounds. In general, they are less basic than the corresponding phosphine oxides, which can adduce to thiophosphoryl halides: [7]: 73
