Spray effectiveness vs time to rain ?
Here is a list of insecticides and fungicides i have seen discussed here which are also readily available and wanted to get your input on how much time before it rains should these chemicals be applied to say be at least 90% effective? Also, if they should be applied in full sunlight or not? I generally spray early morning when the winds are calm.
any other chemicals?
I assume every morning there is dew on the plants so if you spray in a day there is no rain then it should be 100% effective?
I guess it would be helpful to eventually put together a chart which outlines how effective these have been at manufacturers recommended concentration for fighting various pests and also spray regiments.
PS- anyone ever try just putting out those electric bug zappers instead of spray?
