Question

Which amongst the following is a fungicide?
A. \[2 - 4\] D
B. DDT
C. Bordeaux mixture
D. BHC

Answer 1

Hint: The chemical compounds or biological organisms which are being used to kill parasitic fungi or their spores are known as fungicides. Their growth is inhibited by a fungistatic. The growth of fungi can cause serious damage in agriculture which results in critical losses of yield, quality, and profit. The fungicides are used in both agriculture and for fighting fungal infections found in animals.

Complete answer:
Option A \[2 - 4\] D: \[2 - 4\] Dichlorophenoxyacetic acid or \[2 - 4\] D is a common systemic herbicide which is used for the control of broadleaf weeds. \[2 - 4\]-D is one of the most widely used herbicide in the world, has been commercially available since \[1945\]. Since \[2 - 4\] D is a herbicide and not a fungicide.
So, option A is not correct.
Option B DDT: Dichlorodiphenyltrichloroethane, also known as DDT, is a colorless, tasteless, and mostly odorless crystalline chemical compound. DDT is an organochlorine. This chemical compound was originally developed as an insecticide but soon it became infamous for its environmental impacts. Since DDT is an insecticide and not a fungicide.
So, option B is not correct.
Option C Bordeaux mixture: Also known as Bordo mix, the Bordeaux mixture is a mixture of copper sulphate and quicklime, which is used as a fungicide. This compound is mostly used in vineyards, fruit-farms and gardens for the prevention of infestation of downy mildew, powdery mildew and other kinds of fungi. The Bordeaux mixture is commonly used as a fungicide.
So, option B is the correct answer.
Option D BHC: Also known as gamma-hexachlorocyclohexane, lindane or gammaxene are sometimes incorrectly called benzene hexachloride (BHC). Lindane is an organochlorine chemical and hexachlorocyclohexane isomer. This compound has been used both as an agricultural insecticide and as a pharmaceutical treatment for lice and scabies. Since BHC is not a fungicide.
So, option D is not correct.

Therefore, Option C) Bordeaux mixture is the correct answer.

Note:
The residues of fungicide have been found on food for human consumption, which mostly is from post-harvest treatments. Some fungicides such as vinclozolin are dangerous to human health and have now been removed from use. Another fungicide known as Ziram, is toxic to humans with long-term exposure, and fatal if ingested. A number of fungicides are also being used in the field of human healthcare.
