Broad mites, which are tiny and hard to detect, and thrips, which are small winged insects, are additional pests that suck the moisture from zinnias. Total genomic DNA was isolated from infected as well as healthy leaf samples. If they grow inwards, as in begin to curl rather than extend outwards, it’s best to take action early to prevent leaf burn occurring.
