Aphids noticed in the patch on my winter rye!
The closest I can identify these aphids is-- Greenbug (“Schizaphis graminum”)-- based on their general morphology, but it is hard to get an exact identification. The reason I want a close identification is it can help indicate what potential viruses are transmitted by the type of aphid at a higher rate. Last year, I lost my entire patch to ZYMV (Zucchini Yellow Mosaic Virus) with Green Peach Aphids being the likely vector.
Seeing these aphids in the patch does have me concerned, however they do not seem to transmit the typical viruses that infect pumpkin plants at a very high rate, but all it takes is one. So, as a precaution I have ordered Garlic Barrier as a method to try and deter the aphids from coming into the patch. Insecticides are basically useless as all the aphid has to do is pierce the plant tissue, it can die just after doing this and still transmit the virus. Idea with the Garlic Barrier is to prevent them from coming in contact with the pumpkin plants in the first place as this is the only way to prevent the infection from occurring.
