Additional activities should be performed by the CAC for metam sodium applications when air temperatures are expected to exceed 100 degrees. Which of the following is NOT one of the actions?

The choice that is not one of the actions to be performed by the CAC when air temperatures are expected to exceed 100 degrees is the option regarding conducting a pre-application site inspection as soon as the CAC is notified of the intended application. In the context of applying metam sodium, it is critical to conduct site inspections as close to the application date as possible. This timing is essential because environmental conditions, particularly air temperature, can change rapidly and significantly affect the application process and its potential impact.

While early inspections can provide useful information, they do not adequately account for the specific conditions that may exist right before the application. The other actions mentioned represent proactive measures meant to ensure the safety and efficacy of the application, particularly under high-temperature conditions, which can increase the volatility and risks associated with pesticide use. Conducting thorough site checks closer to application time allows for accurate assessment of site conditions, proper management of irrigation capabilities, and monitoring of soil moisture and temperature, all of which are crucial to mitigate potential risks associated with high temperatures.
