Question

Write the full name of 2,4-D and gives its only one use in agriculture?

Answer 1

Biopesticide are toxic chemicals substances that are used to irradicate the pests and protect the useful plants and other organisms.
Depending upon the kind of pathogen or organism they destroy, the chemical substances are known as - herbicides, fungicides, bactericides, insecticides, nematicides, and acaricides.
Biopesticides are the pesticides of biological origin or the biological control agents which are used to control the weeds and pests. They are of two types - bioherbicides and bioinsecticides.

Complete answer: 2,4-D is expanded as 2,4-Dichlorophenoxy acetic acid.
1. Herbicides are the chemical substances used as eradicates of weeds.
2. There are more than 550 herbicides available.
3. The chemical method of weed control is easier, less time consuming and less expensive as compared to other traditional weeding methods.
4. The important herbicides are 2,4,5-T ( 2,4,5-trichlorophenoxy acetic acid),
MCPA (2-Methyl -4-Chlorophenoxy acetic acid ), borates, chlorates, triazines, are used to control broad-leaved weeds of cereal crops and Dalpon is usually used to control grasses in broad-leaved crops.

So, the correct answer is “2,4-Dichlorophenoxy acetic acid ”.

Additional Information: The chemical herbicides are of two types - selective herbicide and nonselective herbicides. There are several serious repercussions associated with the application of herbicides.
One of them is the persistent nature of some organic herbicides which do not breakdown easily.
Moreover, they damage the crop plants themselves and encourage the growth of resistant weeds.
Therefore the biological methods of controlling weeds are more effective and economic.

Note: As the enzymes are secreted by living cells and they speed up chemical reactions, they are known as biocatalysts. The reactant in an enzyme-catalyzed reaction is called the enzymes substrates and the substance produced in the reaction is termed as a product.
