Fungicides and antibiotics are chemicals that:
a. enhance yield and disease resistance
b. kill pathogenic fungi and bacteria, respectively
c. kill all pathogenic microbes
d. kill pathogenic bacteria and fungi respectively.
In agriculture, fungi are significant pathogens that inflict substantial harm upon crops, leading to decreased yield. To combat these fungi and the subsequent spread of their spores, agriculturalists utilize specific substances known as fungicides. These chemical agents are designed to eradicate or inhibit the growth of fungi. Furthermore, bacteria represent another class of microbial organisms that induce diseases in both flora and fauna through direct infiltration of their hosts or contamination of consumable substances like food and water. In order to effectively eliminate these bacteria, bacteriocides are employed, which are chemicals that exhibit bactericidal properties.
Hence, The answer is option (b) kill pathogenic fungi and bacteria, respectively.
