I am half way through flower and I've found the first signs of thrips, but no adults. I'm debating if its safe to spray for them at the moment or if I should just finish the flower and then sterilize the whole room afterwards.
Old thread...I know.....But I just sprayed Safer brand bug spray on the bottoms of all my plants that had thrip damage on them at week 4 exactly. Day 28.
The buds down on the bottoms were teeny-tiny and just had very small white hair clusters. Will this poison the start of the buds so whomever smokes them will smoke chemicals.... or will the buds be ok to smoke after they grow?
I didnt spray anywhere near the nice buds in the middles or tops.
diatomaceous earth is your saving grace when thrips (WFT) are attacking your plants. I had thrips hatching every 3 days and sprayed them with spinosad many times but they would not go away. After adding diatomaceous earth there numbers almost completely stopped. Had done soil drenches of spinosad with some success but they would come back after 5-7 days. Used bombs, spinosad, pure green spray and azatrol with limited success. diatomaceous earth was my saving grace. Works great against all soft bodied insects.
Hope that helps
