No, it's not true. Daconil works by coating the plant, so you'll want to spray all surfaces of the plant as best you can. Follow the directions on the peel-back leaflet attached to the back of the bottle as to mixing and application.

I have also heard of a nursery that used Daconil as a systemic drench but I would follow suze9 advice. Farkee

Ummm. Follow label directions.

My label directions say I should use at 7 to 10-day intervals. Does this mean I spray for 7-10 days and then stop? Or should I spray every 7 to 10 days? Thanks.

Spray thoroughly once and the wait 7 to 10 days before spraying again. Be sure to spray the whole plant, including top and underside of leaves and stems. Pay attention to the weather (don't spray right before rain or when leaves are wet; dont spray when it's windy) and time of day (any pesticide will burn plants in full sun; spray at end of the day). Read and follow the directions exactly (don't use more or less than is called for; don't add anything to the solution that isn't called for on the lable). Wash any produce from sprayed plants before eating it. Wear gloves and a mask (a kerchief will do.)
