Which agronomy product is a systemic broad-spectrum herbicide commonly used in glyphosate-tolerant crops?
Glyphosate
Dicamba
Atrazine
Paraquat
Glyphosate is a non-selective, systemic herbicide widely used in glyphosate-tolerant crops. It moves within the plant to inhibit an essential enzyme pathway, effectively killing treated weeds.
Which fertilizer provides primarily nitrogen to crops?
Gypsum
Potassium sulfate
Urea
Superphosphate
Urea contains about 46% nitrogen, making it a high-analysis nitrogen fertilizer. It is widely used for its high N content and cost-effectiveness.
What is the main function of a fungicide in crop protection?
Prevent fungal diseases
Control insect pests
Control weed growth
Provide essential nutrients
Fungicides are formulated to prevent or control fungal pathogens that cause plant diseases. They can act on the surface or be absorbed systemically by the plant.
Which application tool is most suitable for applying granular fertilizers?
Airblast sprayer
Fertilizer spreader
Backpack sprayer
Boom sprayer
A fertilizer spreader is designed to distribute granular products evenly across a field. Boom sprayers and backpack sprayers are intended for liquid applications.
Which piece of safety equipment is essential when handling concentrated agrochemicals?
Steel-toe boots
Sunglasses
Ear plugs
Chemical-resistant gloves
Chemical-resistant gloves protect skin from exposure to concentrated agrochemicals and reduce the risk of absorption or chemical burns. They are a critical part of personal protective equipment.
What information is conveyed by a fertilizer labeled 10-20-10?
10% N, 20% K₂O, 10% P₂O₅
10% N, 20% P₂O₅, 10% K₂O
10% P₂O₅, 20% N, 10% K₂O
10% K₂O, 20% N, 10% P₂O₅
Fertilizer grades list percentages of nitrogen (N), phosphate as P₂O₅, and potash as K₂O in that order. Thus, 10-20-10 means 10% N, 20% P₂O₅, and 10% K₂O.
A contact fungicide differs from a systemic fungicide in that it:
Provides nutrition to the plant tissues
Works only in soil drench applications
Remains on the plant surface and protects against direct contact
Is absorbed and translocated within the plant
Contact fungicides stay on the plant surface and create a protective barrier against infection. Systemic fungicides are absorbed and move within the plant to reach pathogens.
Which soil additive is used to improve water infiltration in drought-affected soils?
Insecticide
Crop growth regulator
Soil wetting agent
Herbicide
Soil wetting agents, or surfactants, reduce surface tension of water to enhance infiltration in drought-stressed soils. They help water penetrate hydrophobic soil layers.
What is the primary role of a spreader-sticker adjuvant in spray applications?
Lower the pH of the spray mix
Prevent drift by increasing droplet size
Foam control in the tank
Reduce surface tension for better coverage
Spreader-sticker adjuvants reduce surface tension to help spray droplets spread evenly across the leaf surface and adhere better. They improve coverage and retention of the active ingredient.
Which adjuvant type buffers spray solution pH to enhance herbicide stability?
Defoamer
Drift retardant
Surfactant
pH buffer
pH buffer adjuvants stabilize the spray solution's pH, preventing degradation of pH-sensitive herbicides. This helps maintain efficacy during and after tank mixing.
Which droplet size classification is recommended to minimize drift during herbicide application?
Very fine
Fine
Coarse
Ultra-fine
Coarse droplets have enough mass to resist air currents, reducing drift potential compared to finer droplets. They are preferred when drift control is critical.
Which nitrogen fertilizer is considered slow-release due to a polymer coating?
Polymer-coated urea
Urea-ammonium nitrate solution
Ammonium nitrate
Anhydrous ammonia
Polymer-coated urea releases nitrogen gradually as the coating breaks down, improving nitrogen use efficiency. Other forms like anhydrous ammonia release nitrogen more quickly.
In pesticide formulation terminology, what does the abbreviation EC represent?
Emulsion concentrate
Extra concentrate
Emulsified compound
Emulsifiable concentrate
EC stands for emulsifiable concentrate, a formulation where the active ingredient is dissolved in oil and mixed with an emulsifier for dilution in water. It allows easy mixing and application.
If a pesticide contacts the skin, what is the immediate recommended action?
Rinse thoroughly with water and soap
Apply a barrier cream over the area
Continue application and wash later
Ignore if no irritation occurs
Immediate washing with water and soap removes pesticide residues from the skin, reducing absorption and irritation risk. Delaying washing can increase exposure and health hazards.
To improve soil structure in sodic clay soils, which amendment is most suitable?
Potassium chloride
Gypsum
Lime
Elemental sulfur
Gypsum supplies calcium that replaces sodium on soil exchange sites, improving aggregation and structure in sodic clay soils. Other amendments do not directly replace sodium.
Before large-scale tank mixing of different agrochemicals, which compatibility test should be conducted?
Jar test
Soil titration
Viscosity check
Fog test
A jar test simulates small-scale mixing of products in water to observe physical or chemical incompatibilities such as precipitation. It prevents costly application failures.
For maize, splitting nitrogen application at which growth stage improves nitrogen use efficiency?
VT tasseling stage
V6 growth stage
R1 silking stage
V3 growth stage
Applying nitrogen at the V6 stage aligns nutrient availability with peak uptake demand, enhancing efficiency and reducing losses. Early or very late applications are less synchronized.
Which type of surfactant is least likely to cause crop phytotoxicity?
Nonionic surfactant
Amphoteric surfactant
Cationic surfactant
Anionic surfactant
Nonionic surfactants are generally milder and less likely to disrupt plant cell membranes, reducing the risk of leaf burn. Cationic and anionic types can be more aggressive.
In calcareous soils with high pH, which iron chelate formulation is most effective to correct iron chlorosis?
FeSO4
Fe-EDDHA
FeCl3
Fe-EDTA
Fe-EDDHA remains soluble at high pH values and is less prone to precipitation, making it the most effective chelate for iron correction in calcareous soils. Other forms become unavailable quickly.
What document provides critical handling, storage, and transport information for a pesticide product?
Product brochure
Safety Data Sheet
Purchase invoice
Application record
A Safety Data Sheet (SDS) outlines hazards, safe handling, storage, and emergency procedures for chemicals, including pesticides. It is required by regulations for transport and workplace safety.
