Benzene hexachloride as a termite repellent

Bhc (benzene Hexachloride) Formulations

Experience in Queensland has shown that when crude BHC is refined to yield products containing higher proportions of the gamma isomer, the insecticidal persistence of the BHC in soil is decreased. This process also diminishes the specific toxicity of BHC to the soldier fly pest, Alfe~nzetopon.ia rubriceps (Macq.). I t also decreases the potential phytotoxicity, since less total BHC is required ...

Benzene hexachloride poisoning; report of a case with recovery.

Garlic as a tick repellent.

In their Research Letter, Ms Stjernberg and Dr Berglund1 documented a repellent effect of garlic against an unnamed species of tick and stated that daily consumption of 1200 mg of garlic was an alternative to “other agents that might have more adverse effects.” Based on the design of their study, any conclusions concerning the relative effectiveness and safety of garlic as a tick repellent are ...

Inhibition of Growth by Benzene Hexachloride Isomers and Protective Effect of Glucose as Measured by Cell Counting Technique.

The purpose of this study is to evaluate the effects of benzene hexachloride isomers on root growth and the antagonism of these effects by selected chemical compounds. Interest has developed in gamma benzene hexachloride because it is highly toxic to insects (40). Five isomers of benzene hexachloride have been isolated (19) and the structural properties of most of them are well understood (40)....

The influence of humidity on the residual action of benzene hexachloride (BHC).

In controlled humidity chambers in the laboratory differences in the absorption velocity of BHC were observed depending on the substrate sprayed. While BHC is no longer used in Chagas' disease control this data could have relevance to spraying houses in a control programme with other insecticides.
