Maize Termite Troubles Quiz Quiz

Assess your knowledge of termite control strategies in maize cultivation, including identification, prevention, and management techniques. Sharpen your understanding of effective and sustainable approaches for managing termite issues in agriculture.

1. Identifying Termite Damage

   Which of the following is a common sign of termite infestation in a maize field?

   1. Yellowing leaf tips only
   2. Chewed cob kernels
   3. Wilted plants with hollow stems
   4. Black mold on leaves

   Explanation: Wilted maize plants with hollowed-out stems indicate termites feeding on internal tissues, disrupting water uptake. Black mold on leaves is usually associated with fungal disease, while yellowing leaf tips can result from nutrient deficiency. Chewed cob kernels suggest damage by rodents or birds, not termites.

2. Cultural Control Methods

   What farming practice can most effectively reduce termite populations before planting maize?

   1. Increasing irrigation only
   2. Applying lime
   3. Planting closer together
   4. Removing crop residues

   Explanation: Removing and destroying crop residues eliminates potential food and shelter for termites, reducing their numbers before the next crop. Increasing irrigation may deter some termites but isn't a primary control method. Planting seeds closer does not affect termite presence, and applying lime targets soil pH, not termites.

3. Chemical Control Use

   When is the optimal time to apply approved termiticides to protect maize crops?

   1. During cob filling
   2. During harvest
   3. After tasseling
   4. At planting

   Explanation: Applying termiticides at planting protects young maize roots when they are most susceptible to termite attack. Using chemicals after tasseling or during cob filling is often too late, as earlier root damage may have occurred. Spraying at harvest also provides no benefit for current season plants.

4. Natural Predators and Biological Control

   Which of the following can naturally help control termite populations in maize fields?

   1. Armyworms
   2. Ants
   3. Stinkbugs
   4. Weevils

   Explanation: Some ant species are termite predators and can help suppress their populations. Armyworms, weevils, and stinkbugs are crop pests themselves and do not control termites; in fact, they can add to plant stress and damage.

5. Integrated Management

   Why is integrated pest management (IPM) recommended for termite control in maize farming?

   1. Depends solely on heavy pesticide use
   2. Focuses on single-crop systems
   3. Combines multiple strategies for better results
   4. Favors mechanical weeding only

   Explanation: IPM involves combining cultural, biological, and chemical strategies for more effective and sustainable termite control. It does not rely solely on pesticides, does not focus strictly on mechanical weeding, and actually encourages crop diversity rather than single-crop systems.
