Which of the following is NOT broadly classified as a part of agrochemicals?
Fungicides
Digesicides
Insecticides
Herbicides
Digesicides
Agrochemicals are chemical products used in agriculture to enhance crop growth and protection. 'Digesicides' is not a scientific term or a recognized category of agrochemicals; the term is likely a distracter created by combining 'digestive' and 'cide' (meaning to kill).

If your garden is a house, agrochemicals are the specialized staff: Fungicides are the janitors cleaning up mold, Insecticides are the security guards keeping pests out, and Herbicides are the landscapers removing unwanted weeds.
F-I-H: Fungicides, Insecticides, Herbicides are the 'Big Three' chemical crop protectors.
LD50тАЛ тАФ The dose required to kill 50% of a test population, used to measure chemical toxicity.
Conc=volume┬аof┬аsolventmass┬аof┬аsoluteтАЛ тАФ Fundamental calculation for preparing agrochemical solutions.
Agrochemicals work through specific biochemical pathways: Fungicides inhibit fungal respiratory enzymes or cell wall synthesis. Insecticides often act as neurotoxins (e.g., organophosphates inhibiting acetylcholinesterase, or neonicotinoids binding to nicotinic acetylcholine receptors). Herbicides target plant-specific pathways like photosynthesis (e.g., photosystem II inhibition) or amino acid biosynthesis (e.g., EPSP synthase inhibition).
Agrochemicals include fertilizers, soil conditioners, and pesticides (fungicides, insecticides, herbicides, rodenticides).
Pesticide classification is based on the target organism (e.g., -cide suffix means to kill).
Proper application is critical to prevent environmental runoff and soil accumulation.
Regulatory bodies monitor the 'Maximum Residue Limit' (MRL) for food safety.
Increased crop yields and food security
Protection of crops from massive pest or disease outbreaks
Potential for soil and water contamination
Development of chemical resistance in target populations
Harm to non-target beneficial organisms like pollinators
Large-scale commercial farming
Horticulture and pest control in greenhouses
Digesicides is not a legitimate biochemical term.
Fungicides protect against pathogenic fungi, Insecticides against harmful insects, and Herbicides against unwanted vegetation.
B is correct тАФ Digesicides is not a recognized category of agrochemicals, whereas the others are standard types used in agricultural pest management.
In competitive exams, always watch for suffixes. Words ending in '-cide' (from Latin 'caedere', to kill) usually refer to pest control agents, but confirm if the root (like 'fugi' or 'insecti') represents a valid biological organism.
