What is necessary to activate Solicam?

Solicam, which contains the active ingredient norflurazon, is a pre-emergent herbicide that requires moisture to become activated in the soil. Once it is applied, sufficient moisture helps dissolve the herbicide and allows it to bind to soil particles, creating a protective barrier that prevents the germination of weeds.

Moisture is crucial not just for activation, but also for ensuring that the chemical can properly interact with the weeds it is intended to control. Without adequate moisture, the herbicide may remain in a dormant state and fail to provide effective weed prevention, leading to inadequate control of unwanted vegetation.

In the context of the other choices, sunlight, severe pruning, and wind do not play a role in Activating Solicam's effectiveness. Sunlight may be beneficial for plant growth, but it does not affect the activation of the herbicide. Severe pruning of plants may change the conditions of the foliage but does not impact the soil-based activation of the herbicide. Wind can influence the application process or movement of herbicide but does not contribute to its activation mechanism in the soil.
