You could just irrigate, or yes, apply again. Numerous instances of poor weed control occur each year because of the lack of rain or an irrigation event within 7 days of preemergence application. Additionally, irrigating-in the herbicide is an excellent method to prevent losses due to volatility and lateral herbicide leaching. Turfgrass preemergence herbicides essentially do not leach in downward direction beyond a depth of 2 to 3 inches due to binding to soil colloids and organic matter. But they can move laterally, particularly if heavy rainfall occurs shortly after application. Thus, irrigation will usually improve weed control and will help to prevent lateral movement.

It depends on how you applied, if you mixed with water and sprayed you may need to re apply. If you spread the granules then just wait for it to rain.

Hello, Michael, If you use this product in an area that won't get wet; i.e. near sprinklers, etc. one application can last two to three weeks. We spray this around the edges of our home and it really helps keep the ant population from visiting inside our home!

Covered about 100 linear feet. It lasts as long as the rain holds off. When it rains you need to reapply.

Depends on rainfall, temperature, and application conditions. About a month if you want an average.

I have not noticed any as of yet. We had a storm a few weeks back where we got over 7 inches of rain in two days. Did not see any then but if it was a very small amount it may have dried up before I took cover off at next use of grill. We are suppose to have rain tonight and tomorrow. I will check after it stops raining to make sure.Kenny

No sensor-this is how to use rain delay: When in AUTO , press + button for 24 hrs, 48 hrs, or 72 hrs. Screen will flash between clock and hoursremaining before programmed cycle resumes. To remove rain delay, turn dial to OFF and then back to AUTO.

Instructions say"let nature take its course, put it on when it's dry. If really bad, repeat after 6 weeks" it just keeps getting better and better over time. Not an instant change, but it gets lighter everyday.

The short answer is yes. If like me you have repeated fungal issues, season after season, then it's going to be necessary. A light rain - maybe you can skip one application. But after sustained rains then absolutley, yes.

According to the label, it could be good for up to one year. I would wait and see if it is still effective after all your rain. If you see white flies starting to appear again, then re-apply. I live in So. Ca and we only had 4 inches of rain total this year. When I see the insects re-appearing again, I re-apply.

You will need to give it some time to dry before it rains, but it doesn't require long. Several hours per the bottle. I think it recommends not mowing before use, and then not mowing for several days after as well. It is absorbed through the leaves so if you mow and cut them all off, you will decrease its effectiveness, and if you mow after applying the same will happen.

You want to apply 3-5 layers total and wait 5 minute between each layer. After all applications are completed, let dry for at least 8-10 hours. Then you are ready to pump the air back in and enjoy.

Apply every 10 - 14 days depending on your environment. I water every 14 days for my needs

It is primarily meant for outside. You should only have to reapply about once a month unless you really get a deluge or downpour. I use the same brand but for deer to keep them from eating my hostas, and I usually reapply every 3-4 weeks unless it storms.
