So, I sprayed 2 acres of BEDS about 2-3 weeks ago.. Talstar .5 oz per 1000 rate, 2.25 gal per 1000.. All plants did well, very little browning or other damage.. blue cedars, evergreens of every type, and size.. non-evergreens also did well.. no problems with one exception.. Weeping Blue Atlas Cedars.. Some are only slightly browning, others are severly browning.. from the inside of the tree, tips are fine. These cedars are showing browning on at least 3 different sites, one of which is 30 miles away.. It was a hotish day, and we sprayed from 9 am til 6 pm.. same results regardless.. Any thoughts? Is the weeping blue atlas cedar a weak breed?
