Illinois Field Crop Applicators Practice Test

POST is an abbreviation for which type of herbicide application?

1. Post emergence applications

2. Pre evasive applications

3. Permanent application strategies

4. Post-planting strategies

The correct answer is: Post emergence applications

POST stands for post-emergence applications, which refers to the method of applying herbicides after the targeted crops or weeds have emerged from the soil. This timing is crucial because it allows the herbicides to effectively target actively growing weeds that compete with crops for resources such as light, water, and nutrients. By applying post-emergence herbicides, applicators can manage weed populations more effectively since the herbicides are designed to work on specific growth stages of the weeds. The other options do not accurately reflect what POST means in the context of herbicide application. Pre evasive applications, for instance, suggests a timing that does not align with the typical growth cycle of crops and weeds. Permanent application strategies imply a long-lasting solution rather than targeting specific life stages, and post-planting strategies do not specifically address the timing related to when to apply herbicides after crops or weeds have emerged.
