Surflan Pro Herbicide (Oryzalin 40.4%) can be applied around junipers but will not suppress dandelions per the product label instructions.

Surflan Pro Herbicide (Oryzalin 40.4%) can be effected by that much rain if the treated soil is displaced.
Surflan products are known to be pretty thick and will likely clog the hose end sprayer. The other problem with using the hose end sprayer for the Surflan application is that they are not very accurate and you can wind up dispensing more/less product than needed in a given area which can lead to less than desirable results. Surflan Pro should be applied in late fall and again in early spring for pre-emergent control. Pre-emergents work best when the temperatures have been between 55-60 Degrees for 3-5 consecutive days. In Georgia, that is usually between February - May. Please take a look at our Lawn Care Schedule guide for more assistance.
No, Surflan Pro is not safe for use on a dichondra lawn.
You could potentially apply Suflan Pro Herbicide with a post-emergent herbicide as long as neither label prohibits such use and both can be used in the same areas. However, you want to be sure that you are applying your products at the optimal time for the weeds you are targeting. Pre-emergents must be applied before weeds germinate, which is usually when soil temperatures are between 50-55 degrees. Post-emergent herbicides will be most effective when target weeds are young and actively growing; for most herbicides this is in the range of 60-85 degrees. Be sure to calibrate products properly, and if you are mixing two products that have not previously been verified to work together, it is best to do a small jar test for compatability first.
