too much light can kill the fungal spores

if the air temp is always humid it allows for the fungus (dew) to never leave the host which will cause disease
describe the process of herbicide activation and indicate how this process affects efficacy of soil-applied herbicides?
herbicide activation occurs when the herbicide is applied and the host absorbes the chemical. it can affect soil-applied herbicides because if the ground is too hard it will not be able to reach into the soil properly. you want the herbicide to reach atleast 2 inches into the soil.
