Too bad Canine Heritage is going out of the DNA testing business. I've had 4 mixed breed dogs tested by them, two of them also by Wisdom. Didn't send any pictures to either. Canine Heritage was quite accurate on all 4, whereas Wisdom faltered on both less than at least 50%.
The lettuce root aphid is a soil dweller that attacks lettuce roots in spring and summer, causing lettuce plants to wilt and occasionally die. In fall, this species often moves to poplar trees, where it overwinters in the egg stage and produces leaf galls in spring.
There are several preventative sprays that can be used in the early spring to keep the aphids out and stop them from laying their eggs. Many of these sprays are natural and free of chemicals. Items such as sea weed, hot pepper and coriander spray are detested by aphids and many of their unwelcome friends.
