Smart Spraying & Drenching Quiz Quiz

Discover key crop protection practices in agriculture, focusing on efficient spraying and drenching methods that help manage pests and diseases while promoting healthy plant growth.

1. Purpose of Targeted Spraying

   Which is the primary goal of targeted spraying in crop protection, such as applying insecticide only where pests are present?

   1. Increase labor costs
   2. Attract pollinators
   3. Reduce chemical usage
   4. Change soil pH

   Explanation: Targeted spraying is designed to minimize unnecessary chemical use by focusing only on affected areas, reducing costs and environmental impact. Increasing labor costs is generally not desirable. Attracting pollinators and changing soil pH are unrelated to the direct aim of targeted spraying.

2. Understanding Drenching

   In crop protection, what does 'drenching' involve when controlling soil-borne diseases?

   1. Applying solution directly to roots
   2. Pruning infected stems
   3. Spraying over leaves
   4. Using pesticides in the wind

   Explanation: Drenching means administering a liquid treatment to the soil or root zone, allowing the solution to reach plant roots directly. Spraying over leaves addresses foliage pests, pruning removes infected plant parts, and using pesticides in the wind is ineffective and environmentally risky.

3. Nozzle Choice Impact

   Which factor is most affected by the choice of nozzle during pesticide spraying in agriculture?

   1. Seed color
   2. Droplet size control
   3. Storage temperature
   4. Harvest timing

   Explanation: Nozzle selection primarily determines the size of sprayed droplets, influencing coverage and reducing drift. Seed color, harvest timing, and storage temperature are unrelated to nozzle function in spraying practice.

4. Timing of Fungicide Application

   Why is it important to apply fungicides at recommended growth stages of crops like wheat or rice?

   1. Delay crop maturity
   2. Increase fertilizer need
   3. Promote weed growth
   4. Maximize disease protection

   Explanation: Applying fungicides at the right growth stage improves their effectiveness against diseases. It does not increase fertilizer need, delay maturity unnecessarily, or promote weed growth, which are unrelated goals.

5. Safety in Chemical Application

   What is a key safety practice when preparing sprayers for pesticide application?

   1. Storing with food supplies
   2. Wearing protective equipment
   3. Applying on windy days
   4. Mixing by bare hand

   Explanation: Using protective equipment helps prevent chemical exposure and health risks. Spraying on windy days increases drift, mixing with bare hands is unsafe, and storing with food supplies can cause contamination.
